What Causes Sensitive Teeth?

If you sometimes find the taste of something hot or cold painful on your teeth, you may suffer from sensitive teeth.

Sensitive teeth is a common problem which may be caused by cavities and fractured teeth.

But it can also be caused by worn tooth enamel, a cracked tooth or an exposed tooth root.

Tooth enamel is the strongest substance in the body and it protects the crowns of healthy teeth. A layer called cementum protects the tooth root under the gum line.

The part underneath the enamel and the cementum is called dentin, which is less dense than enamel or cementum.

The dentin contains small hollow tubes or canals called tubules. When the dentin loses its protective covering, the tubules allow hot, cold, acidic or sticky foods to reach the nerves and cells inside the tooth.

This causes hypersensitivity and occasional discomfort but fortunately, the irritation does not cause permanent damage.

Following proper oral hygiene helps prevent the gums from receding and causing the pain of sensitive teeth.

Brushing your teeth incorrectly or even brushing too much can cause gum problems.

Your dentist will advise you on the best daily routint to maximize your oral hygiene.

How braces can be made to look good

Orthodontic appliances such as braces can be used to help straighten out crooked and crowded teeth.

This is not just about looking better; it also helps improve your dental health.

How they look may determine how you feel about wearing them but, these days, braces can be as inconspicuous as you want.

Brackets the part of the braces that attaches to each tooth can sometimes be attached to the back of the tooth, making them less noticeable.

The brackets can be made in a wide range of different materials such as metal, ceramic or plastic.

They can also be designed to look appealing. For example, they may be clear or tooth-colored. There can also be shaped in a variety of ways like hearts and footballs or created in favorite colors.

You could even go for gold-plated braces or glow-in-the-dark retainers!

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 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.

Caring for people who have special needs

People at any age can have a condition that makes it difficult for them to look after their own dental health.

This could affect people who suffer from a wide range of conditons such as stroke, spinal cord injury, multiple sclerosis, mental retardation, Down syndrome, genetic disorders, Alzheimers disease or arthritis.

However, people in all of these categories have the same dental needs as everyone else – they need daily brushing and flossing, regular dental visits and a balanced diet.

There are some steps caregivers can take to make it easier to look after people in those categories.

If the person is uncooperative or uncontrollable, try to explain what you are about to do and schedule the task for a time of day when they are rested.

Move in a calm, slow, reassuring manner to avoid startling them. Give praise and encourage them when they help themselves.

Support the persons head, and take special care to prevent choking or gagging when the head is tilted back.

If the person is unable or unwilling to keep their mouth open, your dentist will explain how you can make and use a mouth prop.

Ask your dentist for advice on how to care for people with special needs and check if they have facilities for caring for these needs in the dental office.

How older adults can handle dry mouth and taste problems

Reduced saliva flow that results in a dry mouth is a common problem among older adults.

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

Some of the common problems associated with dry mouth include:
– Constant sore throat
– Burning sensation
– Problems speaking
– Difficulty swallowing
– Hoarseness or dry nasal passages

Left untreated, dry mouth can damage your teeth. Without adequate saliva to lubricate your mouth, wash away food, and neutralize the acids produced by plaque, extensive cavities can form.

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

Another issue that can affect older adults is a loss of appetite due to a change in your sense of taste. Besides an age-related decrease in the sense of taste and smell, certain diseases, medications and dentures can contribute to a decrease in your sense of taste.

Whether you are suffering from dry mouth or problems with your sense of taste, your dentist will be able to make suggestions to help.

Why its not inevitable that youll lose your teeth as you get older

Advancements in dental techniques and the increased focus on preventive dentistry means older adults are keeping their natural teeth longer than ever before.

A survey by the National Institute of Dental and Craniofacial Research showed that the rate of toothlessness in the 55 to 64 age group has dropped 60 percent since 1960.

Whatever your age, its important to practice good oral hygiene at home and to visit your dentist regularly. A few simple steps can help you maintain good oral health throughout your life.

Plaque, the sticky, colorless layer of bacteria that causes tooth decay and gum disease, can build up quickly on the teeth of older adults, particularly when they neglect oral hygiene. This can increase the risk for tooth decay and periodontal disease.

So its important to brush your teeth twice a day with fluoride toothpaste, and clean between your teeth daily with floss or interdental cleaners.

Regular dental checkups are also an important part of caring for your teeth.

This can help you save your teeth and gums and prevent other dental problems. It will save you time and money in the long-run as well.

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.

How cancer treatment affects oral health

When someone is undergoing cancer treatment, its important that they involve their dentist in their program of care.

They should schedule a dental exam and cleaning before the treatment actually begins and then repeat it periodically during the course of treatment.

Its important that they tell the dentist that they are being treated for cancer and that they also discuss any dental procedures, such as extractions or insertion of dental implants, with the oncologist before starting the cancer treatment.

Its therefore a good idea to ensure that the dentist and oncologist have each others details to enable them to discuss any issues to help the patient.

And the dentist and physician should be informed about any issues such as bleeding of the gums, pain, or unusual feeling in the teeth or gums, or any dental infections.

Maintaining excellent oral hygiene during cancer treatment is vital to reduce the risk of infection and to help aid the treatment process.
