The early years of dentistry and teeth

Although there have been huge advances in dental care in recent years, there are records of people dealing with teeth going back over thousands of years.

Here are some of the key dates from the early years in the development of dentistry.

5000 BC: A Sumerian text describes tooth worms as the cause of dental decay.

2600 BC: Hesy-Re, an Egyptian scribe, often called the first dentist, dies. An inscription on his tomb includes the title the greatest of those who deal with teeth, and of physicians.

500-300 BC: Hippocrates and Aristotle write about dentistry, including the eruption pattern of teeth, treating decayed teeth and gum disease, extracting teeth with forceps, and using wires to stabilize loose teeth and fractured jaws.

166-201 AD: The Etruscans practice dental prosthetics using gold crowns and fixed bridgework.

500-1000: During the Early Middle Ages in Europe, medicine, surgery, and dentistry, are generally practiced by monks, the most educated people of the period

700: A medical text in China mentions the use of silver paste, a type of amalgam.

1130-1163: A series of Papal edicts prohibit monks from performing any type of surgery, bloodletting or tooth extraction. Barbers often assisted monks in their surgical ministry because they visited monasteries to shave the heads of monks and the tools of the barber trade sharp knives and razors were useful for surgery. Following the edicts, barbers assume the monks surgical duties: bloodletting, lancing abscesses, extracting teeth, etc.

1210: A Guild of Barbers is established in France. Barbers eventually evolve into two groups: surgeons who were educated and trained to perform complex surgical operations; and lay barbers, or barber-surgeons, who performed more routine hygienic services including shaving, bleeding and tooth extraction.

1400s: A series of royal decrees in France prohibit lay barbers from practicing all surgical procedures except bleeding, cupping, leeching, and extracting teeth.

How sealants can give your teeth extra protection

Sealants are made from plastic material applied to the back teeth to protect the enamel from plaque and acids.

The plastic bonds into the depressions and grooves (pits and fissures) of the chewing surfaces of the back teeth – premolars and molars.

Although thorough brushing and flossing can help remove food particles and plaque from smooth surfaces of teeth, the toothbrush bristles cannot reach all the way into the depressions and grooves to extract food and plaque.

The benefit of sealants is that they protect these vulnerable areas by “sealing out” plaque and food.

Your dentist can apply sealants quite easily and it takes only a few minutes to seal each tooth.

The teeth being sealed will first be cleaned. Then the chewing surfaces are roughened with an acid solution which makes it easier for the sealant to stick to the tooth.

The sealant is then ‘painted’ onto the tooth enamel, where it bonds directly to the tooth and hardens.

Sometimes a special curing light is used to help the sealant harden.

As long as the sealant remains intact, the tooth surface will be protected from decay.
They usually last several years before a reapplication is needed. Your dentist will check the condition of the sealants during your regular visits and reapply them when necessary.

Sealants are ideal for children because the risk of developing pit and fissure decay starts early in life. However, many adults can benefit from sealants as well.

Your dentist can tell you whether sealants would help your oral hygiene program.

Root canal treatment

Root canal therapy is an important treatment that can save a tooth with a diseased nerve and which in the past would probably have needed to be removed.

Inside each tooth is the ‘pulp’ which runs like a thread down through the root and provides nutrients and nerves to the tooth. It is the soft tissue that contains nerves, blood vessels and connective tissue.

If the pulp is diseased or injured, the pulp tissue dies.

The most common cause of pulp death is a cracked tooth or a deep cavity. Both of these problems can let bacteria enter the pulp.

So, if you don’t remove it, your tooth gets infected and you could lose it.

After the dentist – or endodontist (a dentist who specializes in problems of the pulp) – removes the pulp, the root canal is cleaned and sealed off to protect it. Then your dentist places a crown over the tooth to help make it stronger.

Most of the time, a root canal is a relatively simple procedure involving one to three visits with little or no discomfort.

Your restored tooth could last a lifetime, if you continue to care for your teeth and gums and enjoy regular checkups.

The process of installing Invisalign

Invisalign is a system of clear mouthguards that can be used instead of braces to help straighten teeth.

The big advantage is that Invisalign looks better and is more comfortable than braces.

However, not everyone is a candidate for using the system so you with have to check with your dentist.

If an orthodontist certified in Invisalign says you can benefit from the system, they will take impressions of your mouth, write up a detailed specification and then send everything to a high-tech lab.

Next, the lab will show the orthodontist a preview of the appliances.

The lab then makes a series of aligners – depending on the situation, you may need between 12 to 48 aligners.

After the impression of the teeth is taken, it will normally require a visit to the orthodontist every six weeks.

Some patients will be advised to wear metal braces for a period and then switching to Invisalign when their mouth is ready.

For many people Invisalign provides an ideal way of making their smile look better.

How dentistry has developed over the last 300 years

When you visit a modern dental surgery, its hard to imagine the challenges of dental treatment without all the latest technology.

Yet specialists have been taking care of peoples teeth for thousands of years.

Here are some of the key developments over the last 300 years.

1723: French surgeon Pierre Fauchard – credited as being the father of modern dentistry – publishes the first book to describe a comprehensive system for the practice of dentistry.

1760: John Baker, the earliest medically-trained dentist to practice in America, immigrates from England and sets up practice.

1790: John Greenwood adapts his mothers foot treadle spinning wheel to rotate a drill.

1790: Josiah Flagg, a prominent American dentist, constructs the first chair made specifically for dental patients.

1832: James Snell invents the first reclining dental chair.

1841: Alabama enacts the first dental practice act, regulating dentistry in the United States.

1844: Horace Wells, a Connecticut dentist, discovers that nitrous oxide can be used as an anesthesia and successfully uses it to conduct several extractions in his private practice.

1880s: The collapsible metal tube revolutionizes toothpaste manufacturing and marketing.

1890: Willoughby Miller notes the microbial basis of dental decay in a book which started a world-wide movement to promote regular toothbrushing and flossing.

1896: New Orleans dentist C. Edmond Kells takes the first dental x-ray of a living person in the U.S.

1938: The nylon toothbrush, the first made with synthetic bristles, appears on the market.

1945: The water fluoridation era begins when the cities of Newburgh, New York, and Grand Rapids, Michigan, add sodium fluoride to their public water systems.

1950s: The first fluoride toothpastes are marketed.

1960: The first commercial electric toothbrush, developed in Switzerland after World War II, is introduced in the United States. A cordless, rechargeable model follows in 1961.

Whats involved in getting a dental implant?

Dental implants are increasingly popular as a way to replace missing or damaged teeth.

Their great advantage is that they look natural and feel secure helping you to restore your smile and eat more easily.

Implants are an ideal solution for many people but they are not an option for everyone.

Placing implants requires some surgery so patients must be in good health, have healthy gums and have adequate bone to support the implant.

They must also be committed to taking action to maintain their oral hygiene and to visiting the dentist regularly.

The process for placing implants is as follows:

First, surgery is performed to place the anchor. This can take up to several hours. Following the surgery, you may need to wait up to six months for the bone to grow around the anchor and firmly hold it in place. Sometimes follow up surgery is required to attach a post to connect the anchor to the replacement teeth. Alternatively, the anchor and post may already be attached and are placed at the same time.

After the gums have had several weeks to heal, the next step is to fit specially-made artificial teeth to the post portion of the anchor. This can take a few weeks to complete as several fittings may be required.

Implant surgery can be done either in a dental office or in a hospital, depending upon a number of factors. A local or general anesthetic may be used. Usually pain medications and, when necessary, antibiotics are prescribed.

After your implants are fitted, your dentist will give you tips and advice on maintaining your oral hygiene.

Your dentist can help you decide whether you would be a good candidate for implants.

How dental x-rays help improve your oral health

Many diseases of the teeth and surrounding tissues cannot be seen when your dentist examines your mouth so an X-ray examination can reveal important additional information:

For example, X-rays can help show:
– Small areas of decay between the teeth or below existing fillings
– Infections in the bone
– Gum disease
– Abscesses or cysts
– Developmental abnormalities
– Some types of tumors

The way they work is that more X-rays are absorbed by the denser parts (such as teeth and bone) than by soft tissues (such as cheeks and gums). This creates an image called a radiograph.

Tooth decay, infections and signs of gum disease appear darker because of more X-ray penetration. The interpretation of these radiographs allows the dentist to safely and accurately detect hidden abnormalities.

The frequency of X-rays (radiographs) will depend on your specific health needs.

Your dentist will review your history, examine your mouth and decide whether you need radiographs and what type.

When you are a new patient, the dentist may recommend radiographs to establish how the hidden areas of your mouth currently look to help identify changes that occur later.

X-rays can help identify and treat dental problems at an early stage and so can save time, money and unnecessary discomfort.

The risks of oral piercing

Young people today choose to make a variety of fashion statements affecting not just the clothes they wear but also their bodies through tattoos and piercing, for example.

Oral piercing may be something they feel looks good but it can lead to problems where they end up needing medical or dental treatment.

Oral piercing can often lead to symptoms such as pain, swelling, infection, increased saliva flow and injuries to the gum tissue.

There can be severe bleeding if a blood vessel is in the path of the needle during the piercing.

Swelling of the tongue is also a common side effect and, in extreme cases, this can block the airway and lead to breathing difficulties.

Other possible problems include chipped or cracked teeth, blood poisoning or even blood clots.

Infection is a very common complication of oral piercing because of the millions of bacteria in your mouth.

Of course, the jewelry itself also causes risk. It can be swallowed or cause damage to your teeth.

So, while young people may feel piercings in the mouth look cool, a great smile will look a lot better in the years to come.

How Invisalign can replace metal braces

The Invisalign system is a series of clear, thin, mouthguards that fit over the teeth and can gradually straighten them.

These have been called invisible braces as they can be an effective alternative to metal braces in some circumstances.

The big advantage of Invisalign is much improved appearance and comfort.

Invisalign mouthguards can be removed during eating and when brushing and flossing. As traditional braces may trap food and plaque, this is another major benefit of Invisalign.

While the system has advantages, it also has some drawbacks.

For example, it is more expensive – costing 25-50 percent more than metal braces.

Also the fact that you remove the mouthguards more often means that you may forget to wear them and it could take longer for you to achieve the desired results.

Invisalign is better suited to some people than others – for example, it may be particularly suitable for adults who have slight to moderate spacing or crowding of their teeth.

Your dentist will be able to tell you if you might be a suitable candiate for Invisalign.

You will get more detailed advice from an orthodontist who has been certified in the Invisalign system.

How to stop your dentist using too much jargon

Having a good relationship with your dentist means they should be able to explain things clearly to you and talk to you in language you understand.

The challenge for the dentist is that, as with any type of medical and professional training, they have to learn many unusual and technical terms.

This jargon has a purpsoe as it allows professionals to communicate clearly with each other on the same basis.

But often there is no need to use this terminology with the patient. Using these terms becomes a habit and they forgat to translate for the patient.

Soemtimes. it’s easier to say what you are thinking to a patient rather than have to translate it into something he or she will understand. And the dentist is usually thinking using the jargon.

Many common dental words such as restoration (filling), dentition (set of teeth) and occlusion (how the teeth come together) can easily be translated into terms patients understand.

Your dentist wants to help you understand as much about your dental health as possible so they would prefer that you stop them and ask what terms mean or simply ask them to speak in plain English.

They often slip into jargon out of habit or because it allows them to communicate more easily with others on the team.

They want you to get the treatment you need and be satisfied. So they won’t mind if you stop and remind them to communicate more effectively.

Oral cancer: Why early detection is so important

Although thousands of Americans die every year from oral cancer, there is a high chance it can be cured if it is caught early enough.

Each year, more than 30,000 Americans are diagnosed with oral cancer and only half of those diagnosed survive more than five years.

But nowadays, dentists have the skills and tools to ensure that early signs of cancer and pre-cancerous conditions are identified.

If it is caught early, there is a much higher chance that, with your dentists help, you could win a battle against oral cancer.

The key is to know the early signs and see your dentist regularly.

Oral cancer often starts as a tiny, unnoticed white or red spot or sore anywhere in the mouth.

It can affect any area of the oral cavity including the lips, gum tissue, cheek lining, tongue or the palate.

Other signs include:
– A sore that bleeds easily or does not heal
– A change in the color of the oral tissues
– A lump, thickening, rough spot, crust or small eroded area
– Pain, tenderness, or numbness anywhere in the mouth or on the lips
– Difficulty chewing, swallowing, speaking or moving the jaw or tongue
– A change in the way the teeth fit together

Oral Cancer most often occurs in those who use any form of tobacco. Smoking combined with alcohol use greatly increases the risk.

However, oral cancer  which is most likely to strike after age 40 can occur in people who do not smoke and have no other known risk factors.

Diets with a lot of fruits and vegetables may help prevent its development.

Oral cancer screening is a routine part of a dental examination so regular checkups with an examination of the entire mouth  are essential in the early detection of cancerous and pre-cancerous conditions.

How Osteoporosis medications can affect your dental health

Osteoporosis is a disease that weakens bones and increases the risk of fractures.

It affects about 10 million Americans of whom 8 million are women and another 34 million are at risk of developing it.

So this is a disease that affects more women than cancer, heart disease and stroke combined.

But what does it have to do with your dental care?

Well, many people in these categories are treated with a group of prescription drugs called oral bisphosphonates. Studies have reported that these drugs reduce bone loss, increase bone density and reduce the risk of fractures.

But some people have been alarmed and confused by recent news reports about oral bisphosphonates because of uncommon complications that have been linked to these drugs.

The drugs have been associated with osteonecrosis of the jaw (ONJ), a rare but potentially serious condition that can cause severe destruction of the jawbone.

The true risk posed by oral bisphosphonates remains uncertain, but researchers seem to agree that it appears very small.

Given the risks associated with osteoporosis and the proven benefits of oral bisphosphonate therapy, you should not stop taking these medications before discussing the matter fully with your physician.

If your physician prescribes an oral bisphosphonate, its important to tell your dentist so that your health history form can be updated.

In this case, some dental procedures, such as extractions, may increase your risk of developing ONJ, so your dentist needs to be able to take your full health picture into account.

Different types of fillings and restorations

Nowadays, thanks to advances in dental techniques and materials, patients have a much wider range of choices when they have to repair missing, worn, damaged or decayed teeth.

For example, materials such as ceramics and polymer compounds that look more like natural teeth help dentists create pleasing, natural-looking smiles.

The traditional materials such as gold, base metal alloys and dental amalgam are still widely used as they have many advantages.

The strength and durability of traditional dental materials continues to make them useful in many situations. For example, they are good when fillings are required in the back teeth because the pressure of chewing is high in that area.

The choice of the best option will depend on several factors such as the patient’s oral and general health, where and how the filling is placed and the number of visits needed to prepare and adjust the restored tooth.

The choice about which option is best depends on each individuals needs so you should discuss the options with your dentist.

Your restored tooth could last a lifetime, if you continue to care for your teeth and gums and enjoy regular checkups.

What Causes Sensitive Teeth?

If you sometimes find the taste of something hot or cold painful on your teeth, you may suffer from sensitive teeth.

Sensitive teeth is a common problem which may be caused by cavities and fractured teeth.

But it can also be caused by worn tooth enamel, a cracked tooth or an exposed tooth root.

Tooth enamel is the strongest substance in the body and it protects the crowns of healthy teeth. A layer called cementum protects the tooth root under the gum line.

The part underneath the enamel and the cementum is called dentin, which is less dense than enamel or cementum.

The dentin contains small hollow tubes or canals called tubules. When the dentin loses its protective covering, the tubules allow hot, cold, acidic or sticky foods to reach the nerves and cells inside the tooth.

This causes hypersensitivity and occasional discomfort but fortunately, the irritation does not cause permanent damage.

Following proper oral hygiene helps prevent the gums from receding and causing the pain of sensitive teeth.

Brushing your teeth incorrectly or even brushing too much can cause gum problems.

Your dentist will advise you on the best daily routint to maximize your oral hygiene.

What dentists are doing to improve services for older adults

As people are living longer and enjoying good health for many years, dentists are increasingly offering improved services to recognize the special needs of older adults.

This growing segment of the population is wearing fewer dentures and they are keeping their natural teeth longer. They are also concerned to maintain good health and a great smile for many years.

However, patients in this group sometimes require special consideration because reduced mobility and dexterity may make daily oral hygiene difficult.

And certain medical conditions and impairment may make them more anxious when visiting the dentist.

For example, problems with vision or hearing loss may cause worry. Always let the dentist and staff know if you have any concerns so that they can adjust their treatment and their pace to meet your needs.

Older patients can sometimes put up with problems such as toothaches, bleeding gums and clicking dentures because they are not aware of the wide range of treatments and techniques now available.

Dentists are increasingly sensitive to the special needs of and the importance of dental health in the older patient.

As many older patients are more health conscious than ever before, regular visits to the dentist ensure their oral health is an important part of their overall health.

The facts about oral cancer

Oral cancer is not as well known as other types of cancer but it can represent a life-threatening risk if not identified early.

– It strikes an estimated 35,000 Americans each year
– More than 7,500 people (5,200 men and 2,307 women) die of these cancers each year
– More than 25% of Americans who get oral cancer will die of the disease
– On average, only half of those diagnosed with the disease will survive more than five years
– African-Americans are especially vulnerable; the incidence rate is 1/3 higher than whites and the mortality rate is almost twice as high

Although the use of tobacco and alcohol are risk factors in developing oral cancer, approximately 25% of oral cancer patients have no known risk factors.

There has been a nearly five-fold increase in incidence in oral cancer patients under age 40, many with no known risk factors.

The incidence of oral cancer in women has increased significantly, largely due to an increase in women smoking. In 1950 the male to female ratio was 6:1; by 2002, it was 2:1.

The best way to prevent oral cancer is to avoid tobacco and alcohol use.

Unusual red or white spots can form in and around the mouth. These are often harmless but they can be cancerous or pre-cancerous.

Identifying and removing these early enough is a major factor in reducing the incidence of cancer.

So knowing the risk factors and seeing your dentist for regular examinations can help prevent this deadly disease.

Treating Sensitive Teeth

Sensitive teeth is a common problem that causes many people to feel discomfort with hot or cold foods and drinks.

It can also make it uncomfortable to brush or floss the teeth and therefore can lead to further oral problems.

However, sensitive teeth can be treated.

If you suffer from this, your dentist may suggest that you try a desensitizing toothpaste, which contains compounds that help block transmission of sensation from the tooth surface to the nerve.

For desensitizing toothpaste to work, you normally have to make several applications.

If the desensitizing toothpaste does not help, your dentist may suggest further solutions.

For example, fluoride gel – which strengthens tooth enamel and reduces the transmission of sensations – may be applied to the sensitive areas of the teeth.

If the sensitivity is caused by receding gums, your dentist may use bonding agents that “seal” the sensitive teeth.

The sealer is usually made of a plastic material.

If there is severe hypersensitivity which cannot be treated by other means, there is the option of endodontic (root canal) treatment.

Sensitive teeth is a problem that can stop you enjoying your food but is one that can often be solved.
