Dental plaque – what it is and how to avoid it

You’ve probably heard people talking about plaque and maybe you’ve some idea of what it is.

But its useful to know a bit more about it so that you can do whats necessary to minimize the risks.

Plaque is a sticky film of bacteria that forms on teeth and gums.

When you’ve eaten a meal or snack, the bacteria in plaque release acids that attack tooth enamel. When this happens regularly, the enamel can weaken. This eventually leads to tooth decay.

The food we eat often causes plaque bacteria to produce acids. So, if you eat a lot of snacks, your teeth may be suffering acid attacks all day.

If you don’t remove the plaque through effective daily brushing and cleaning between the teeth, it can eventually harden into calculus or tartar.

Another effect of plaque is that it also produces substances that irritate the gums, making them red and tender or causing them to bleed easily.

If you want to prevent tooth decay and gum disease, make sure you have a balanced diet and avoid having too many snacks between meals.

When you feel like a snack, go for foods such as raw vegetables, plain yogurt, cheese or a piece of fruit.

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.

The power of panormaic x-rays

X-rays are extremely valuable for helping dentists identify issues that may not show up on normal oral examination.

The three most common types of dental X-rays are the bitewing, periapical and panoramic X-rays.

Panoramic X-rays give a broad overview of the entire mouth – supplying information about the teeth, upper and lower jawbone, sinuses, and other hard and soft tissues of the head and neck.

Unlike other X-rays, where the film is placed inside the patients mouth, the panoramic film is contained in a machine that moves around the patient’s head. So they are very easy to use.

Panoramic X-rays are often used to check wisdom teeth but they will also reveal deep cavities and gum disease. They are also useful to help patients with past or present jaw problems or those who require full or partial removable dentures, dental implants, or braces.

They can also be valuable in assisting people who are suspected of having oral cancer or have had recent trauma to the face or teeth.

Panoramic X-rays play an important role in thorough dental examinations and are recommended at least every five years or so for most patients.

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 secrets of brushing and flossing your teeth effectively

Though many of us say we brush our teeth regularly, you get the best results by making sure you brush properly.

Here are the steps you should follow:

First, place the toothbrush at a 45-degree angle to your gums.

Then, move the brush back and forth gently in short (tooth-wide) strokes.

Brush the outer tooth surfaces, the inner tooth surfaces, and the chewing surfaces of the teeth.

Use the “toe” of the brush to clean the inside surfaces of the front teeth, using a gentle up-and-down stroke.

Finally, brush your tongue to remove bacteria and freshen your breath.

As well as brushing your teeth, you should floss them every day. Heres how to floss for best results.

Break off about 18 inches of floss and wind most of it around one of your middle fingers.

Then wind the remaining floss around the same finger on the opposite hand. This finger will take up the floss as it becomes dirty.

Hold the floss tightly between your thumbs and forefingers.

Guide the floss between your teeth using a gentle rubbing motion. Never snap the floss into the gums.

When the floss reaches the gum line, curve it into a C shape against one tooth. Gently slide it into the space between the gum and the tooth.

Hold the floss tightly against the tooth. Gently rub the side of the tooth, moving the floss away from the gum with up and down motions.

Repeat this method on the rest of your teeth.

Don’t forget the back side of your last tooth.

If you have difficulty handling dental floss, consider other types of interdental cleaner such as special brushes, picks or sticks.

Your dentist or hygienist will be able to give your further tips on how to brush and floss for best results.

Why dry mouth can be a problem and what to do about it

Your saliva plays an important role in your oral health and reduced saliva flow can lead to health problems.

Reduced saliva flow can lead to a dry mouth and this is a common problem among older adults.

It can be caused by various medical disorders and is often a side effect of medications such as antihistamines, decongestants, pain killers and diuretics.

Dry mouth can be associated with various problems such as a constant sore throat, burning sensation, problems speaking, difficulty swallowing, hoarseness or dry nasal passages.

Drying irritates the soft tissues in the mouth, which can make them inflamed and more susceptible to infection. Without the cleansing effects of saliva, tooth decay and other oral health problems become more common.

So, if dry mouth is not treated, it can damage your teeth.

Without adequate saliva to lubricate your mouth, wash away food, and neutralize the acids produced by plaque, extensive decay can occur.

Your dentist can recommend various methods to restore moisture. Sugar-free candy or gum stimulates saliva flow, and moisture can be replaced by using artificial saliva and oral rinses.

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.

How smoking affects your teeth

While the general effects of smoking on your health are well-known, it can also have significant effects on your oral health.

Here are some of the ways smoking can harm your oral health and hygiene:

– Oral Cancer
– Periodontal (gum) disease
– Delayed healing after a tooth extraction or other oral surgery
– Bad breath
– Stained teeth and tongue
– Diminished sense of taste and smell

Research suggests that smoking may be responsible for almost 75% of adult gum disease.

Tobacco products damage your gum tissue by affecting the attachment of bone and soft tissue to your teeth. One effect is receding gums which expose the tooth roots and increase your risk of tooth decay or to sensitivity to hot and cold in these unprotected areas.

Cigar smoking is equally a major risk and even smokeless tobacco products contain a variety of toxins associated with cancer. Smokeless tobacco can also irritate your gum tissue.

Giving up smoking will provide a significant boost to your oral health as well as giving you the chance to live longer.

Maintaining proper nutrition as an older adult

Maintaining proper nutrition is important for everyone, young or old but many older adults find it difficult to eat a balanced diet.

They may avoid meats, raw vegetables and fresh fruits because they have trouble chewing or swallowing.

These problems can be caused by painful teeth, ill-fitting dentures, dry mouth or changes in facial muscles.

Others find their sense of taste has changed, sometimes due to a disease or certain medications.

As a result, older adults often have diets lacking in calcium, protein and other nutrients essential to dental and overall health.

A balanced diet has to be based on the five food groups:
– Milk and dairy products
– Breads and cereals
– Meats and dried beans
– Fruits
– Vegetables

Sometimes a multi-vitamin or mineral supplement will help but its best to use supplements only after discussion with your physician.

If your teeth are stopping you from eating the food you enjoy or that you need for good health your dentist will be able to help you find a solution.

Fixing crowded and crooked teeth with orthodontics

Correcting problems with crowded and crooked teeth not only gives you a better smile, it also leads to a healthier mouth.

Malocclusion, also known as bad bite, involves teeth that are crowded or crooked.

Sometimes, the upper and lower jaws may not meet properly and, although the teeth may appear straight, the individual may have an uneven bite.

Problems such as protruding, crowded or irregularly spaced teeth may be inherited. But thumb-sucking, losing teeth prematurely and accidents also can lead to these conditions.

As well as spoiling your smile, crooked and crowded teeth make cleaning the mouth difficult. This can lead to tooth decay, gum disease and possibly tooth loss.

A bad bite can also interfere with chewing and speaking, cause abnormal wear to tooth enamel and lead to problems with the jaws.

Orthodontic treatment can help correcting these problems giving you a better smile but, more importantly, creating a healthier mouth.

Your dentist will advise you on how orthodontic treatment could help you.
