Understanding your wisdom teeth

Many patients ask whether wisdom teeth are really necessary since so many people have them removed.

The fact is that wisdom teeth are a valuable asset to the mouth when they are healthy and properly positioned.

However, problems can occur that sometimes make it better to have them removed.

For example, when the jaw isn’t large enough, the wisdom teeth can become impacted – misaligned or unable to grow in properly. They may grow sideways, emerge only part way from the gum or remain trapped beneath the gum and bone.

The reasons wisdom teeth may have to be extracted include:
– The teeth have only partially erupted. This leaves an opening for bacteria which cause infection.
– There is a chance the wisdom teeth will damage adjacent teeth.
– A cyst forms which may destroy surrounding structures such as bone or tooth roots.

Ask your dentist about the health and positioning of your wisdom teeth.

Your dentist will tell you if there are any issues and will recommend any steps needed.

The difference between canker sores and cold sores

Although canker sores are often confused with cold sores, there is a difference.

Canker sores occur inside the mouth, and cold sores usually occur outside the mouth.

Canker sores are small ulcers with a white or gray base and a red border. There can be one or more sores in the mouth. They are very common and often recur.

They usually heal in a week or two and rinsing with antimicrobial mouthrinses may help reduce the irritation.

Cold sores – also called fever blisters – are composed of groups of painful, fluid-filled blisters that often erupt around the lips and sometimes under the nose or chin.

Cold sores are usually caused by herpes virus type I and are very contagious. They usually heal in about a week.

Over-the-counter topical anesthetics can provide temporary relief and prescription antiviral drugs may reduce these kinds of viral infections.

How braces help both children and adults

Crowded or crooked teeth – known as malocclusion – not only spoil your smile, they also increase your risk of dental health problems.

Corrective procedures and appliances such as braces straighten teeth and correct jaw alignment.

Malocclusions are often noticed around ages 6 – 12, when the adult teeth begin to erupt.

The process of straightening out teeth, known as orthodontic treatment, often begins between ages 8 and 14. The best results are obtained when a child begins treatment while they are still growing.

This means it’s a good idea for a child to have an orthodontic evaluation by age 7. At this stage, they have a mix of baby teeth and adult teeth.

It’s possible for braces to work later � and even in adults � but there are many advantages in starting as soon as possible.

Your dentist will be able to spot problems with emerging teeth and jaw growth early on, while the primary teeth are present.

That’s why regular dental examinations are important.

For adults, it’s not too late to correct problems such as crooked or crowded teeth, overbites, underbites, incorrect jaw position or jaw-joint disorders. The biological process involved in moving teeth is the same at any age.

The difference is that adult treatment takes a little longer than a child’s treatment. As an adult’s facial bones are no longer growing, certain corrections may not be accomplished with braces alone.

But, whatever your age, it’s never too late to improve your dental health and improve your smile.

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 it’s 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 overgrowths 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 it’s particularly important to maintain good oral health during pregnancy. Make sure you clean your teeth carefully and visit your dentist regularly.

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 to make your smile brighter

Your smile makes a huge difference to what people think about you and how you feel about yourself.

And there are many options available to help you improve the look and brightness of your smile, including:

In-office bleaching: During chair-side bleaching, the dentist will apply either a protective gel to your gums or a rubber shield to protect the oral soft tissues. A bleaching agent is then applied to the teeth, and a special light may be used to enhance the action of the agent.

At-home bleaching: There are several types of products available for use at home, which can either be dispensed by your dentist or purchased over-the-counter. These include peroxide bleaching solutions, which actually bleach the tooth enamel. Peroxide-containing whiteners typically come in a gel and are placed in a mouth guard.

Whitening toothpastes: All toothpastes help remove surface stain through the action of mild abrasives. “Whitening” toothpastes include special chemical or polishing agents that are more effective at removing stains. However, unlike bleaches, they don’t alter the intrinsic color of teeth.

Start by speaking to your dentist. He or she will tell you if whitening procedures would be effective for you as whiteners may not correct all types of discoloration.

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.

How to overcome problems with teeth grinding

When under stress, many people find themselves grinding their teeth or clenching their jaws.

This habit actually has a name – bruxism – and often it’s something we do when we sleep.

It can be caused by stress and anxiety and it can also be due to sleep disorders, an abnormal bite or missing and crooked teeth.

It can lead to symptoms such as dull headache or a sore jaw.

Your dentist can fit you with a mouth guard to protect your teeth during sleep.

Severe grinding can lead to painful or loose teeth and this can lead to fractures in your teeth.

Taking stress out on your teeth in this way can lead to long term damage so, if stress is the cause, you need to find a way to relax!

Relaxants, counseling and even exercise may help reduce stress and tension and can be a big help to your teeth.

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.

Some tips on overcoming nerves when going to the dentist

Some people get a bit nervous about the idea of going to the dentist.

As a result of the major progress that has been made in diagnosis and treatment, the process gets more comfortable all the time. So you may be worrying unnecessarily.

But, if you’re in any way tense or anxious, tell your dentist and the dental staff.

They will understand and will be able to adapt the treatment to your needs.

It can also help if you choose a time for your dental visit when you’re less likely to be rushed or under pressure. Dashing out from a busy day at work may make you feel more stressed.

For many people, that means making an early-morning or a Saturday appointment helps a great deal.

There are also other steps than can help. If the sound of the drill bothers you, take a portable audio player and headset so you can listen to your favorite music.

You can also help to relax by simply visualizing yourself somewhere you feel relaxed.

Sometimes these simple steps can help you feel a lot better. So why not give it a try on your next visit?
