Tooth sensitivity is an all too common problem among dental patients. If eating certain foods or simply touching a tooth causes you pain, you should know why this may be happening and what can be done about it.
Tooth sensitivity occurs in most cases because the portion of the tooth known as the dentin has been exposed. The dentin contains nerve fibers that inform and alert the brain about the current environment of the tooth (temperature or pressure changes). The enamel protects the tooth from environmental extremes.
Receding gums are the most common cause for dentin exposure — the enamel only protects the crown of the tooth and is not present on the root of the tooth. Acids in certain foods can then begin to erode the dentin around the roots and expose nerves. Sweet items (mainly sugar) and temperature shifts irritate the nerve endings, causing pain.
While receding gums (most commonly caused by brushing too hard and too often) may be the most common cause for sensitivity, it isn't the only one — tooth decay may also lead to it. Untreated, decay works its way into the tooth pulp and irritates the nerves. Treating the decay and filling the tooth may also cause sensitivity unless the dentist places a lining designed to minimize it temporarily while the area heals.
Alleviating pain from sensitivity begins with how you brush your teeth. Remember: the goal of brushing is to remove plaque, which does not require vigorous action. Brush gently with a soft-bristled brush and not too often. We might even recommend not brushing a very sensitive tooth for a few days to give the tooth a rest. You should also brush with a toothpaste containing fluoride, which will help strengthen the tooth surface against the effects of acids and sweets.
During an office visit, we can also apply a fluoride varnish or use certain filling materials that will serve as a barrier for the sensitive area. For cases where decay has irreversibly damaged the tooth pulp, a root canal may be the best treatment.
Tooth sensitivity isn't necessarily something you have to live with. There are treatments that can relieve or lessen the pain.

Growing up with a dentist stepdad, Cheryl Burke of Dancing with the Stars heard a lot over the years about the importance of good oral hygiene — in particular, the benefits of using dental floss.
“My dad would say, ‘make sure you floss,’ but I never really listened to him. I was very, very stubborn,” Cheryl told Dear Doctor magazine recently in an exclusive interview. Cheryl admits this stubbornness took its toll, in the form of tooth decay. “I definitely had my share of cavities,” Cheryl recalled.
Cavities can form when food particles, particularly sugar and carbohydrates, are not effectively cleaned from the spaces between teeth. These particles are then broken down by bacteria naturally present in the mouth, resulting in the production of acids that attack the tooth enamel.
When she reached her twenties, Cheryl decided she really needed to step up her oral hygiene and cultivate an asset so important to a professional dancer: a beautiful smile. And once she did, cavities became a distant memory.
“I think when you do floss frequently, it helps to reduce the chances of getting cavities,” Cheryl said. “It took me a while to figure it out.” Now Cheryl flosses after every meal. “I carry floss with me wherever I go. I have no shame busting out my floss in the middle of a restaurant!” She declared.
Dental decay is actually a worldwide epidemic, especially among kids. Untreated, it can lead to pain, tooth loss, and, because it is an infectious disease, it may even have more serious systemic (whole body) health consequences. The good thing is that it is entirely preventable through good oral hygiene at home and regular professional cleanings here at the office.
