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 cosmetic dentistry can change your smile – and your life

Modern cosmetic dentistry has created many opportunities that did not exist before for people to improve their appearance and change the way they feel about themselves.
Although cosmetic dentistry really did not exist a few yaears ago, it now attracts interest from a wide range of people.
There are few people who don’t want to improve their appearance by making their teeth straighter and whiter so that they look better when they smile.
New technology and procedures have created many more opportunities for dentists to help patients look better.
One of the most important opportunities for doing this is porcelain veneers.
These are custom-made wafers that the dentist places over the front of the teeth to repair damage and make them look better.
They can overcome many cosmetic dental problems such as whitening stained or discolored teeth, closing gaps between teeth or correcting a crooked smile without the need for braces.
They can also cover up chips and imperfections so that the smile looks much better.
Another important cosmetic trend is the increased use of white fillings.
White fillings now are more lifelike than ever and they last longer than previously.
They have become the material of choice for many dentists as they blend in with teeth and look better.
If you feel your smile is less than perfect, talk to your dentist about how it could be better.

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 dont 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.

Is it safe to have an X-ray while pregnant?

Some women worry about whether its safe to have an X-ray exam while they are pregnant.
This can cause them to put off treatment they need.
However, untreated dental infections can pose a risk to the fetus, and dental treatment may be necessary to maintain the health of the mother and child. Sometimes this will mean an X-ray is necessary.
Radiation from dental X-rays is extremely low but every precaution is taken to minimize radiation exposure.
For example, a leaded apron reduces exposure to the abdomen and should be used when a dental radiograph is taken.
In addition, a leaded thyroid collar can protect the thyroid from radiation, and should be used whenever possible. The use of a leaded thyroid collar is strongly recommended for women of childbearing age, pregnant women and children.
Overall there is no reason to avoid dental radiographs (X-rays) while pregnant, breastfeeding or trying to become pregnant.
Follow your dentists advice and ask questions if you have any concerns.

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.

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.

The keys to keeping your mouth healthy

A healthy mouth is a good indication of your overall health and helps you to keep a great smile and continue eating what you want for many years to come.
There are a few steps you can take to make sure your mouth is as healthy as possible:
- Brush your teeth twice a day using a good quality toothbrush
- Renew your toothbrush regularly. It will only keep your mouth healthy if the brush is in good condition and the bristles are strong. You should replace it at least every three or four months
- Clean between your teeth. Your toothbrush can’t reach everywhere and bacteria can linger between the teeth so its important to clean between them every day using floss or an interdental cleaner
- Visit your dentist regularly for professional cleaning and oral examinations
Your dentist will be able to give you tips on what other products you should consider to help improve your oral health.
For example, antimicrobial mouth rinses and toothpastes can reduce the germs in your mouth and reduce the risk of gum disease.
Also, fluoride mouth rinses can help reduce and prevent tooth decay. Studies have shown that using mouth rinses provides valuable protection over and above that provided by fluoride toothpaste alone.
Look out for the ADA seal when buying toothbrushes and other dental products. This is a sign that the product has met American Dental Association standards for safety and effectiveness.
Following these steps can help ensure that you continue to enjoy great oral health.
