Why are my teeth sensitive?

Why you should pay attention to sensitive teeth

sensitive teethSensitive teeth is a symptom that indicates there have been some changes that the teeth are not happy with. Sensitivity usually is the result of exposure of surfaces of the teeth that would not typically be exposed in a healthy state.

These changes to teeth can be:

  • Due to wear and the resulting exposure of the next layer of the tooth beyond the enamel, which is dentin.
  • Due to recession of the gums that can be accelerated by unfavorable forces on teeth
  • Due to cracks in teeth that are caused by forces or trauma that exceeds what the teeth can handle or restorations can withstand.
  • Due to decay that has invaded the deeper layers of the tooth

What elicits sensitivity?

Usually the sensitivity can be elicited by thermal changes, such as cold beverages, or even biting pressure when chewing food that offers resistance, such as a bagel or a nut.  In essence it’s a cry for help that lets us know that something is wrong.

What should I do?

source of sensitivityThe solution is often two-fold. First your dentist will identify the location and cause of the sensitivity.  Any solution without management of why it happened in the first place will only ensure that the sensitivity will return and probably get worse.  Second, depending on the damage that has resulted in the sensitivity, there may be a variety of solutions.
A common source of sensitivity is recession of the gums around the teeth and the exposure of the root surfaces and/or dentin. Solutions may include:
  • The use of desensitizing or prescription fluoride- toothpastes to help protect the areas causing the sensitivity
  • The application of desensitizing solutions applied by the dentist or dental hygienist
  • The use of a dental laser to alter the surfaces of the teeth to reduce sensitivity
  • The restoration of the teeth to resurface areas of exposed dentin or to eliminate decay.

Proactive prevention is always more cost-effective and easier.
