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 routine to maximize your oral hygiene.

How cancer treatment can affect your oral health

More than 1 million Americans are diagnosed with cancer each year and many of them will develop problems with their oral health as a result of their cancer treatment.

While it’s natural that they’ll be focused on their cancer treatment, it’s important not to overlook the importance of a dental examination as part of the process of maintaining overall health.

For example, radiation therapy of the head and neck area may lead to certain complications such as dry mouth, sensitive lesions in the oral cavity, hypersensitive teeth, rapid tooth decay and difficulty swallowing.

Chemotherapy and other medication can also have significant effects in the mouth.

To help prevent, minimize and manage such problems, the dentist and oncologist can work together – before and during cancer treatment.

Many medications lead to dry mouth, which can lead to a higher risk of gum disease and other problems.

The dentist may therefore recommend a saliva replacement, an artificial saliva that is available over-the-counter at pharmacies.

Frequent fluoride applications may also be recommended.
If you are receiving treatment, schedule regular screenings with your dentist and contact your dentist or physician immediately on any sign of mouth infection.

This may have serious implications for your overall health.

Your dentist and physician both want your treatment to be as safe and effective as possible.

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.

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.

How a healthy diet can help you have healthy teeth

Eating the right food plays an important role in developing healthy teeth and gums.

If your diet lacks certain nutrients, it may be more difficult for tissues in your mouth to fight infection and this can contribute to gum disease.

Although poor nutrition does not cause gum disease directly, the disease may progress faster and could be more severe in people with diets which are low in nutrients.

The U.S. Department of Agriculture makes recommendations on the nutrients, vitamins and minerals needed by your body – including your teeth and gums – to promote health and prevent disease.

We have different needs at various stages life and depending on our physical activity. The DOA website provides more information and your dentist will be able to discuss how your diet affects your teeth.

Here are some steps you can take to make sure what you eat doesn’t harm your teeth.
– Maintain a healthy diet
– Drink plenty water
– Limit the number of between-meal snacks. When you must snack, choose nutritious foods that are low in sugar
– Keep a food diary for a week recording every item you eat and drink

It will also help if you brush your teeth twice a day and floss regularly. Schedule regular dental checkups and professional cleanings and talk to your dentist about how your diet affects your teeth.

Solving the problem of bad breath

Bad breath – which is also known as halitosis – is a worrying problem that can also be embarrassing.

But there's no need to put up with it. If you suffer from bad breath, your dentist will be able to suggest a range of solutions.

Your dentist will be able to spot problems such as gum disease, dry mouth or other disorders. That's why its important to maintain good oral hygiene, schedule regular visits to the dentist and have professional cleaning.

Make sure you brush your teeth twice a day and clean between your teeth each day using floss or interdental cleaners. Don’t forget to brush your tongue, too!

If your dental check up shows that your mouth is healthy, your dentist may refer you to your family physician as sometimes bad breath can be a sign of other health problems.

If the odor is due to periodontal (gum) disease, sometimes professional periodontal cleaning is needed to remove the bacteria and plaque that accumulate. And your dentist may recommend a special antimicrobial mouth rinse.

Keeping your mouth healthy and stopping periodontal disease are essential to reducing bad breath.

So make sure you schedule regular dental visits for a professional cleaning and checkup.

What to do if your tooth cracks

While our teeth are normally very strong, they can crack for a number of reasons.

Reasons could include tooth decay, trauma/injury, grinding of the teeth or a stress fracture.

Sometimes, our jaw may be stronger than our teeth and the teeth can fracture when we bite heavily on food.

We can protect our teeth in some circumstances – for example it may be advisable to wear a mouthguard during sports.

Taking proper care of the teeth and regular visits to the dentist will help keep your teeth in good shape.

If a tooth cracks, it may become painful if the nerve is exposed and the area can become tender.

If this happens, rinse your mouth with warm water to clean the area and apply a cold compress to reduce swelling. Then call your dentist immediately.

Treatment will depend on where the tooth has fractured, how close it is to the nerve and the overall condition of the tooth.

A cracked tooth may be repaired with silver alloy, gold, porcelain or plastic. Or it may require a crown or overlay or bonding, which applies porcelain or enamel to the fractured tooth.

If you contact your dentist quickly, they will be able to take the most appropriate action to preserve the tooth as much as possible.
