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.

Making your teeth look better with veneers

Everybody wants the best smile possible and there’s no need to have it spoiled by gaps in your teeth or by teeth that are stained or badly shaped.

Whether the problem was caused by nature or by an injury, you may be able to have a veneer placed on top of your teeth to restore or improve your smile.

Veneers are thin, custom-made shells crafted from tooth-colored materials designed to cover the front side of teeth.

Your dentist will usually make a model of your teeth and the veneers will be made by a specialist dental technician.

A small amount of enamel has to be removed from your teeth to accommodate the shell so having veneers is usually an irreversible process.

In order to make the most of your veneer, your dentist may suggest that you avoid foods and drinks that could discolor them, such as coffee, tea or red wine.

It’s also possible that veneers might chip or fracture.

But, for many people, veneers are well worth it as they give them a completely new smile.

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.

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, Alzheimer’s 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 person’s 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 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 dental implants can give you a better smile

If you have missing teeth, you don’t just have to rely on crowns, conventional bridges and dentures.

Many people are now choosing dental implants as the best way to restore their smile and solve dental problems.

Implants are placed below the gums during a series of appointments. They fuse to the jawbone and provide a base for individual replacement teeth, bridges or a denture.

As they are fused to the bone, they offer greater stability. And, because they are integrated into your jaw, your replacement teeth will feel more natural.

This secure fit often also makes them more comfortable than other solutions.

In order to have implants, you need to have healthy gums and adequate bone to support the implant.

To find out whether you could be a candidate for dental implants, talk to your dentist about what they could do for you.

Daily dental tips to cut down on plaque

Plaque is a sticky film of bacteria that forms on teeth and gums. If you let it build up on your teeth, it can lead to several problems.

The best way to remove plaque from the tooth surfaces is by brushing and cleaning between your teeth every day.

You should brush your teeth twice a day, with a soft-bristled brush. The brush should fit your mouth comfortably, allowing you to reach all areas easily.

When you use toothpaste that contains fluoride, this helps protect your teeth.

You can help even more by cleaning between the teeth once a day with floss or interdental cleaners. This removes plaque from between the teeth in areas the toothbrush can’t reach.

By taking a few steps each day to look after your teeth – and visiting your dentist regularly, you’ll be able to enjoy healthy teeth and a great smile all your life.

How medication and anesthesia can help make your visit to the dentist easier

Your dentist will do everything possible to make your visit as relaxed and comfortable as possible.

Depending on the treatment you are receiving, there are several medications available to help.

Some drugs control pain, some help you relax and others put you into a deep sleep during dental treatment.

The best approach will depend on the type of procedure being undertaken, your overall health – including any history of allergies – and the degree of anxiety you feel.

Some of the options your dentist might discuss include:

Analgesics: These are the most commonly used drugs for relief of toothache or pain following dental treatment. They includes aspirin, acetaminophen and anti-inflammatory drugs such as Ibuprofen. There is a separate category of ‘narcotic analgesics’ – such as those containing codeine – which are used for more severe pain.

Local anesthesia: Topical anesthetics are applied to mouth tissues with a swab to prevent pain on the surface level. They may also be used to soothe mouth sores. Injectable local anesthetics prevent pain in a specific area of your mouth during treatment by blocking the nerves that sense or transmit pain and numbing mouth tissues.

In other cases, your dentist many recommend sedation or general anesthesia.

Your dentist will discuss the best approach to suit your needs.

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.

How sugar in your diet affects your teeth

The sugar content in the food you eat has a big effect on your teeth and gums.

When bacteria (plaque) come into contact with sugar in the mouth, acid is produced, which attacks the teeth for 20 minutes or more. This can eventually result in tooth decay.

That’s why drinking sugar-filled sodas, sweetened fruit drinks, and non-nutritious snacks can take a toll on teeth.

This is particularly true for children as their eating patterns and food choices affect how quickly they develop tooth decay.

Foods that contain sugars of any kind can contribute to tooth decay. However, almost all foods, including milk or vegetables, have some type of sugar. Many of them also contain important nutrients that are an important part in our diet.

To help control the amount of sugar you consume, read food labels and choose foods and beverages that are low in added sugars. Soft drinks,candy, cookies and pastries often contain added sugars.
