Everyone has experienced a sensitive tooth. Actually, some level of sensitivity is considered normal since teeth are enervated with pain nerves. However, when teeth become abnormally sensitive, a cause is usually detected. The most obvious source is dental decay, which destroys enamel and dentin, causing pain when the irritants produced are liberated, reaching the nearby pulp nerves. Obviously, the treatment here is to remove the decay and replace it with a restoration (filling). It should be stressed that teeth
since this disease destroys the supporting tissue surrounding the teeth, which again exposes the roots. Another source of sensitivity occurs when enamel (which contains no nerves) is lost thereby exposing the sensitive dentin below, where nerve endings are present. Enamel can be lost from excessive bruxing (grinding), or from a diet too rich in acids such as carbonated beverages and most citrus fruit drinks, which dissolve enamel. What measures can you take if you suffer experience excessive sensitivity?

Brushing too vigorously, and improperly will lead to the eventual loss of some gingiva and\or enamel, thereby exposing the root where nerves are again irritated; cold air or liquids will irritate these areas. This type of sensitivity is becoming more common as people become more conscious of there dental health. You should only brush with a toothbrush made of soft bristles. Periodontitis (gum disease) is an extremely common source of sensitivity since this
apply desensitizing agents such as fluoride as well as other products which can help to decrease sensitivity. A toothpaste made to combat sensitivity, (Sensodyne, Prevident), and home fluoride rinses, (ACT or Flourigard), can help to some degree. Should these measures prove ineffective and the offending tooth remains intolerable, your dentist may perform root desensitization via an applied medication or root sealant to almost instantaneously relieve the problem. The only stipulations are that there is a minimal cost and the treatment may need to be redone in 6-12 months if and when it begins to recur. If everything else fails, in the worst case scenerio, a root canal treatment (removal of pulp nerves) which would render the tooth completely insensitive to any hot or cold stimulus could be performed, if absolutely necessary.If you presently suffer from sensitive teeth, only your dentist can evaluate your situation and provide a treatment specific to your needs.
