Do your teeth feel sensitive to hot cold or sweet food???

Why does someone develop sensitivity??

There could be two reasons for sensitivity to develop

1.The outer most covering of the tooth is called Enamel. Enamel is the hardest part of the human body, harder than bone. It is impervious to oral fluids. But when enamel wears off it exposes dentin (erosion) which has tubules in it and conducts the temperature in the mouth on to the nerves in the pulp. This cases sensitivity.
2.Sometimes root surface may be exposed in people (due to various reasons like faulty brushing, drinking soda etc.,) and the root is covered by cementum not enamel and may be the reason for sensitivity.

Causes for erosion:
1.Faulty brushing habits
2.Night grinding
3.Acidic diet
5.Gastric acidity with lot of belching
6.Excessive tooth whitening procedures
7.Bulimia etc.,


1.The dentist has to identify if there is a cavity
If yes : it needs to be filled
2.If No: then your dentist may recommend some desensitizing tooth pastes to be used and may be some fluoride varnish application. Some dietary modifications like eliminating soda and acidic food from your routine may also be advised.
3.Cervical aberrations (cavities in the neck of the teeth) can also be identified and filled
4.If the tooth cannot be restored with fillings it may need Root canal treatment
5.You will be advised on oral hygiene maintenance
Sensitivity can be quite annoying interfering with your daily life. At times it may be difficult to differentiate between sensitivity and pain.
It is recommended that in case you are experiencing any discomfort please meet the dentist at the earliest
