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.

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.

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 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.

Things to look out for during pregnancy

Every woman wants to maintain their own health during pregnancy and to take whatever steps are necessary to give the baby the best possible start.

There are a few factors in your oral health to look out for during this time.

One consideration is that its common for pregnant women to have the urge to eat between meals. The risk is that frequent snacking on carbohydrate-containing foods can encourage tooth decay.

Bacteria in your mouth called plaque can convert the sugar and starch in your mouth into an acid that attacks tooth enamel. After repeated attacks, tooth decay can result.

So, when you need a snack, try to choose foods that are nutritious for you and your baby such as raw fruits and vegetables and dairy products.

During pregnancy, your body’s hormone levels rise considerably. Gum problems, such as gingivitis, are especially common during the second to eighth months of pregnancy. They may cause red, puffy or tender gums that bleed when you brush.

This is an exaggerated response to plaque caused by higher levels of progesterone in your system. Your dentist may recommend more frequent cleanings at some stages to help you avoid problems.

Occasionally over growths of gum tissue, called pregnancy tumors, appear on the gums during the second trimester. These localized growths or swellings are usually found between the teeth and are thought to be related to excess plaque.

They bleed easily and are often surgically removed after the baby is born.

Studies indicate that pregnant women who have severe periodontal (gum) disease may be at increased risk for pre-term delivery, which in turn increases the risk of having a low-birth-weight baby.

So its particularly important to maintain good oral health during pregnancy. Make sure you clean your teeth carefully and visit your dentist regularly.

Is bottled or tap water better for your teeth?

With many people concerned about the taste and purity of tap water, the sales of bottled water have increased significantly in recent years.

Tap water goes through a process of purification designed to eliminate suspended materials, remove tastes and odors and kill microorganisms.

Fluoride is added to most tap water supplies with the aim of reducing cavities.

Fluoride becomes incorporated into our teeth as they develop and makes them more resistant to decay. It can reverse the progress of early cavities and reduce the need for dental treatment.

Mass water fluoridation has played an important role in reducing tooth decay.

The problem with bottled waters is that they usually don’t contain fluoride.

So there is a risk that drinking bottled water can increase the risk of cavities for some people.

If you drink a lot of bottled water, you can make up for this by using fluoride toothpaste and mouth rinse.

Your dentist may even suggest a fluoride supplement if they notice an increase in cavities.

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.

How your oral health links with your general health

Research has shown strong links between periodontitis (advanced form of gum disease) and other health problems such as cardiovascular disease, stroke and bacterial pneumonia.

And pregnant women with periodontitis may be at increased risk of delivering pre-term and/or having babies with low birth weight.

However, just because two conditions occur at the same time, doesn’t necessarily mean that one condition causes the other. The relationship could work the other way.

For example, there is evidence that diabetics are more likely to develop periodontitis and have more severe periodontitis than non-diabetics.

Alternatively, two conditions that occur together may be caused by something else.

In addition, people who smoke or use alcohol have a higher than average risk of developing periodontitis and other conditions, including oral cancer.

Research is looking at what happens when periodontitis is treated in individuals with these problems.

The aim is to find out whether periodontitis does have an effect on other health problems.

If one caused the other, improvement in periodontal health would also improve other health problems.

While the research is not yet conclusive, the potential link between periodontitis and systemic health problems, means that preventing periodontitis may be an important step in maintaining overall health.

In most cases, good oral health can be maintained by brushing and flossing every day and receiving regular professional dental care.

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.

Why a dental abscess should be treated quickly

If you have any kind of swelling in your gum, it almost certainly indicates a serious infection that should be treated urgently.

Dental abscesses result from a bacterial infection in the teeth or gums.

For example, it may come from an untreated cavity. Cavities result when some of the bacteria in our mouths mix with sugars and starches in our diet to produce acid.

This acid attacks the hard enamel coating of our teeth and, as the cavity gets deeper, it eventually infects the nerve and blood supply of the tooth.

In some cases, a dental abscess is caused by an infection of the gum. Bone loss from gum disease can create a pocket between the tooth, gum and bone.

When bacteria and other debris get into this pocket, an abscess can form.

The treatment for an abscess depends on how severe the infection is.

If the abscess has been caused by decay, root canal treatment may be needed or the tooth may even have to be removed.

If the abscess has been caused by the gum, the gum will need deep cleaning or surgical treatment. Again the tooth may need to be removed.

Sometimes, a small incision may be made into the gum to drain the abscess. If this happens, antibiotics and pain medication may be used to relieve discomfort.

If you wait until the gum is severely swollen before seeking treatment, the situation can become very serious.

The abscess at this stage can prevent you breathing properly and can be life-threatenting.

So if you have any signs of swelling in your gum, contact your dentist immediately.
