ToothSensitivityFAQs

It can start with a simple twinge or be as severe as excruciating pain. From time to time, we have patients asking questions about tooth sensitivity — what causes it? What can be done about it? For these reasons, we have put together the following list of frequently asked questions (FAQs) so that you can develop a healthy understanding about this painful and often avoidable condition.

What is tooth sensitivity?

The first layer of protection of the teeth is enamel. Enamel is a dense crystalline structure, the hardest substance produced by animals. It is an inert substance that has no nerve supply and thus it protects the teeth from temperature and pressure changes. When it is compromised, worn thin, or exposed due to gum recession, it leaves the dentin exposed and vulnerable. Unlike enamel, dentin is living and has delicate nerve fibers within it.

What triggers tooth sensitivity?

Once dentin is exposed, it can become sensitive. It typically occurs when the dentin comes in contact with heat, cold, or the “double whammy” combination of both cold and sweets. Even the bristles of a soft toothbrush can irritate exposed dentin causing sensitivity and pain.

What can be done to minimize tooth sensitivity?

One of the simplest ways to minimize or prevent sensitivity is by teaching proper brushing techniques so that teeth are cleaned without causing either sensitivity or damage. Brushing too hard is a frequent culprit. Being overzealous can literally cause gum recession, leave dentin, and wear it away leaving it grooved. Another step to minimize sensitivity is to use a toothpaste containing fluoride. Fluoride increases the strength of tooth surfaces and thus makes teeth more resistant to attack by acids and sweets. If severe, we may need to apply a barrier to cover the sensitive areas. These barriers may range from concentrated fluoride varnishes to replacing lost tooth structure with filling materials.

GoodOralHygieneMadeAlltheDifferenceforBallroomDanceStarCherylBurke

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.

If it has been a while since you or your children have seen us for a cleaning and check-up, or you just want to learn more about preventing tooth decay, please contact us to schedule an appointment for a consultation.
