What Causes Sensitive Teeth?
Tooth Sensitivity is Caused by the Exposure of Dentine
Tooth sensitivity is caused by the gradual exposure of the softer part of your tooth that lies under the tooth enamel, called dentine. Dentine has tiny tubes (tubules) that are filled with fluid. Eating or drinking foods and drinks that are hot, cold or sweet can cause this fluid to move. This fluid movement causes the nerve endings in your teeth to react in response, triggering a twinge of discomfort or a short, sharp pain.
Where are the common dental conditions?
You will find some useful answers about teeth sensitivity on this website but if you are concerned that your sensitivity may indicate a more serious condition, make sure to also schedule an appointment with your dentist or dental hygienist.
- e.g. from tooth grinding or overly frequent tooth brushing
The sensitivity which can be experienced during and after professional tooth whitening (bleaching) treatments is different from dentinal hypersensitivity why/how?.
