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.

How sugar in your diet affects your teeth

The sugar content in the food you eat has a big effect on your teeth and gums.

When bacteria (plaque) come into contact with sugar in the mouth, acid is produced, which attacks the teeth for 20 minutes or more. This can eventually result in tooth decay.

Thats why drinking sugar-filled sodas, sweetened fruit drinks, and non-nutritious snacks can take a toll on teeth.

This is particularly true for children as their eating patterns and food choices affect how quickly they develop tooth decay.

Foods that contain sugars of any kind can contribute to tooth decay. However, almost all foods, including milk or vegetables, have some type of sugar. Many of them also contain important nutrients that are an important part in our diet.

To help control the amount of sugar you consume, read food labels and choose foods and beverages that are low in added sugars. Soft drinks,candy, cookies and pastries often contain added sugars.

Common mouth sores: causes and cures

Mouth sores can be very annoying and painful and can have many causes.

The causes can range from infections – bacterial, viral or fungal – to a loose orthodontic wire or a denture that doesn’t fit or a sharp edge from a broken tooth or filling.

But mouth sores may be symptoms of an underlying disease or problem.

So, if you’ve had any mouth sore that lasts a week or longer, it’s a good idea to get your dentist to check it out.

Here are some of the most common mouth sores:

Canker sores: These are small ulcers with a white or gray base and a red border. They appear inside the mouth and are not contagious though they often return. Problems such as poor immune systems, viruses or fatigue and stress may be involved. They usually heal on their own after a week or two.

Cold sores: Cold sores are annoying and painful. They are also known as fever blisters or Herpes simplex and are groups of fluid-filled blisters. They often erupt around the lips and sometimes under the nose or around the chin. Cold sores caused by herpes virus type 1 are very contagious and the virus stays in the body. Cold sore blisters usually heal in a week by themselves.

Candidiasis: This fungal infection (also called moniliasis or oral thrush) occurs when the yeast Candida albicans reproduce in large numbers. It is common among denture wearers and people who have dry mouth syndrome are very susceptible to it. The focus is on preventing it or controlling the conditions that caused the outbreak.

Any mouth sores that last more than a few days should be checked with your dentist.

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.

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.

Common questions about dental insurance

Understanding what’s covered by your dental insurance is an important part of making sure you get the best oral care possible.

Here are some common questions that arise when people want to understand their cover better.

– If treatment my dentist recommends is not covered by my insurance, does that mean it’s not necessary?

Some plans make exclusions such as sealants, pre-existing conditions, adult orthodontics, and specialist referrals. This depends on your dental plan and you should not let the level of cover determine whether you need treatment.

– My dental benefit will only pay for a large filling but my dentist recommends I get a crown. Which should I choose?

Some plans will only cover the least expensive solution but it may not be the best option for your needs. You should decide based on your health needs and not on your insurance cover.

– My dental plan says it will pay 100 percent for checkups and cleanings but the insurance company says I owe for part of the dentist’s charge. How can this be?

Some plans provide cover based on a “customary fee” for each procedure. So, if your dentist’s fee is higher, your benefit will be based on a percentage of the customary fee instead of your dentist’s fee. Although these limits are called “customary,” they may not accurately reflect the fees that dentists charge in your area.

– Will my plan cover the care my family will need?
If your employer offers more than one plan, check the exclusions and limitations of the coverage as well as looking at the general benefits. It’s a good idea to discuss your family’s likely needs with your dentist before choosing a plan.

The plan document should specify who is eligible for coverage under the plan.

Plans offered by the same provider or employer can vary according to the contracts involved so your dentist will not be able to answer specific questions about your benefit or predict what the coverage for a particular procedure will be.

If you have specific questions about coverage, talk to your plan provider.

Your saliva and why its so important

You probably don’t give too much thought to the saliva in your mouth but, if you think of it like a bloodstream you’ll realize how important it is.

Like blood, saliva helps build and maintain the health of the soft and hard tissues.

It removes waste products from the mouth and offers first-line protection against microbial invasion that might lead to disease.

Saliva is derived from blood and therefore can also be used to detect disease.

Saliva enhances enamel protection by providing high levels of calcium and phosphate ions. It contains the minerals that maintain the integrity of the enamel surface and helps protect against caries.

When salivary flow is reduced, oral health deteriorates – much in the same way body tissues suffer if blood circulation is disrupted.

Patients with dry mouths (xerostomia) experience difficulty chewing, speaking and swallowing. A major cause of dry mouth is medication – almost eighty percent of the most commonly prescribed medications lead to dry mouth.

Chewing gum after a snack or meal stimulates salivary flow, clearing food from the mouth and neutralizing plaque acid.

Your saliva is important to your oral health both for preventing disease and in helping to diagnose problems.
