Why cavities arent just for kids

Tooth decay or cavities result from destruction of the tooth enamel and can lead to a range of problems from toothache to bad breath.
Cavities occur when foods containing carbohydrates (sugars and starches) such as milk, sugared drinks, cakes or candy are frequently left on the teeth.
Bacteria that live in the mouth thrive on these foods, producing acids as a result. Over a period of time, these acids destroy tooth enamel, resulting in tooth decay.
Many people associate cavities with children but the changes that occur with aging make cavities an adult problem, too.
Recession of the gums away from the teeth, combined with an increased incidence of gum disease, can expose tooth roots to plaque.
Tooth roots are covered with cementum, a softer tissue than enamel. They are susceptible to decay and are more sensitive to touch and to hot and cold. The majority of people over age 50 have tooth-root decay.
Decay around the edges of fillings is also common to older adults. As many of them did not benefit from fluoride and modern preventive dental care when they were younger, they often have a number of dental fillings.
Over the years, these fillings may weaken, fracture and leak around the edges.
Bacteria accumulate in these tiny crevices causing acid to build up which leads to decay.
You can help prevent tooth decay by following these tips:
– Brush twice a day with fluoride toothpaste
– Clean between your teeth daily with floss or interdental cleaner
– Eat nutritious and balanced meals and limit snacking
Its also worth asking your dentist about supplemental fluoride, which strengthens your teeth, and about dental sealants, a plastic protective coating which is applied to the chewing surfaces of the back teeth to protect them from decay.
In addition, its important to visit your dentist regularly for professional cleanings and oral examination.

Diabetes and your dental health: How your diet can affect your teeth

When diabetes is not controlled properly, high glucose levels in saliva may create problems that lead to an increased risk of tooth decay.
Your teeth are covered with plaque, a sticky film of bacteria. After you eat food that contains sugars or starches, the bacteria react with these sugars to release acids that attack tooth enamel. This can cause the enamel to break down and may eventually result in cavities.
Brushing twice a day with fluoride toothpaste and cleaning between your teeth with floss or an interdental cleaner helps remove decay-causing plaque.
Plaque that is not removed can eventually harden into calculus, or tartar. When tartar collects above the gumline, it becomes more difficult to clean thoroughly between teeth. This can lead to chronic inflammation and infection in the mouth.
Because diabetes reduces the bodys resistance to infection, the gums are among the tissues likely to be affected.
Periodontal diseases are infections of the gum and bone that hold your teeth in place. Patients with inadequate blood sugar control appear to develop periodontal disease more often and more severely, and they lose more teeth than those who have good control of their diabetes.
Because of the lower resistance and longer healing process, periodontal diseases often appear to be more frequent and more severe among persons with diabetes.
You can help reduce these risks through good maintenance of blood sugar levels, a well-balanced diet, good oral care at home and regular dental 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.

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.

How braces can be made to look good

Orthodontic appliances such as braces can be used to help straighten out crooked and crowded teeth.
This is not just about looking better; it also helps improve your dental health.
How they look may determine how you feel about wearing them but, these days, braces can be as inconspicuous as you want.
Brackets the part of the braces that attaches to each tooth can sometimes be attached to the back of the tooth, making them less noticeable.
The brackets can be made in a wide range of different materials such as metal, ceramic or plastic.
They can also be designed to look appealing. For example, they may be clear or tooth-colored. There can also be shaped in a variety of ways like hearts and footballs or created in favorite colors.
You could even go for gold-plated braces or glow-in-the-dark retainers!

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.

How mouth protectors can save your teeth

If you take part in sports that carry a significant risk of injury, you should wear a mouth protector.
Accidents can happen during any physical activity and, if you participate in sports such as football, hockey, basketball, baseball, gymnastics and volleyball, you might be grateful for the extra protection one day.
Something as simple as a misdirected elbow in a game, or a spill off a bicycle, can leave you with chipped or broken teeth, nerve damage to a tooth or even tooth loss.
Mouth protectors usually cover the upper teeth and they can cushion the effect of a blow to the face, reducing the risk of broken teeth and injuries to the soft tissues of the mouth.
In addition, if you wear dental appliances such as braces on your lower jaw, your dentist may suggest a mouth protector for these teeth as well.
A properly fitted mouth protector will stay in place while you are wearing it, making it easy for you to talk and breathe. The three main types of mouth protectors are:
Stock: These are inexpensive and come ready to wear. But they often don't fit very well and they can be bulky making breathing and talking difficult.
Boil and bite: These can also be bought at many sport stores and may fit better than stock mouth protectors. You first soften them in water, then insert them and allow them to adapt to the shape of your mouth.
Custom-fitted: Protectors that are specially made for you by your dentist are more expensive but are likely to fit better than one you buy off the shelf.
Choosing to wear the right mouth protector can help you avoid serious long-term damage to your teeth and mouth.
