To understand tooth sensitivity lets take a closer look at the layers of a tooth.
A tooth is composed of 3 main layers; enamel, dentin and pulp. The pulp is the innermost layer and houses all of the tooth's living components, nerves and blood vessels. Dentin is the middle layer; the bulk or largest layer of the tooth. Lastly, the outermost layer is called enamel; the hardest, most mineralized tissue in the body.
Inside the dentin, or middle layer, are thousands of tiny tubes. These tubes extend from the outer layer of pulp to the outer layer of dentin. If left exposed, thousands of nerves are open to the surface. When enamel is worn away or gums have receded, leaving the dentin uncovered, nerves are triggered and pain is felt.
Tooth sensitivity is one of the most common complaints of dental patients, and studies have found that about 40 million Americans suffer at some point from sensitivity.
So what can you do?
Toothpaste
Sensodyne, Colgate and Crest offer a wide range of sensitivity toothpastes. These products contain ingredients that work by either blocking the opening of the tubes or desensitizing nerve endings. The most common mistake people make with sensitivity toothpaste is only using it when they feel sensitive! Most of these toothpastes need a few weeks to begin working and require continued long term use.
Fluoride
A fluoride treatment can be done in-office and is a quick, useful remedy. Fluoride puts back all the minerals and vitamins into the tooth; strengthening it. This treatment is done every 4-6 months and has great success!
Desensitizing Agent
Your dentist can also prescribe a prescription strength fluoridated paste to use at night. These products are great for those who will consistently use them daily. The most common of these prescription products are Clinpro and Prevident.
Acidity
Several drinks and foods are very acidic and will break down the enamel on your teeth, causing sensitivity. If you are experiencing sensitivity, take a look at your diet. Sodas, lemons, sports drinks, energy drinks; using these daily or long term could be the culprit of your sensitivity.
Clenching or Bruxism
Bruxism is a nocturnal habit of grinding your teeth, and most are unaware that they do it! Some signs of clenching or grinding are: flattened tops of teeth, "dished" out tops of molars, jaw pain, frequent headaches or gum recession.
Recent Dental Treatment
If you have had recent dental treatment done you may be experiencing sensitivity. This is normal! Don't worry! This sensitivity should be acute and go away within a few days. If sensitivity is lingering, call your dentist for a consultation.
There are several things you can do daily to help prevent or lessen the sensitivity response. First, make sure your toothbrush has soft or extra soft bristles, and brush gently! Most people brush vigorously and end up "brushing" off their enamel. A good way to know if you are brushing too hard is to take a look at your toothbrush. If the bristles are spread sideways, you are brushing too hard.
Get into your dentist for a dental cleaning twice a year. Some tooth sensitivity can be stemming from decay, a dying tooth, or clenching at night. Your dentist can give you a proper diagnosis by taking radiographs and doing a thorough exam.
Don't live with tooth sensitivity! There are several treatment options or ways to relieve the pain depending on your situation! Talk to your dentist or dental hygienist about ways that they can help you.
