As we get older the hard enamel coating on our teeth can wear away naturally, exposing the more sensitive dentine layer underneath, and this can mean our teeth become sensitive to hot and cold foods.  Teeth are particularly vulnerable to sensitivity at the point where the gum and tooth meet, as this is where the enamel layer is thinnest.

What Causes Sensitive Teeth?

A number of factors can cause sensitive teeth including over brushing and brushing with a side to side action, which can wear away the enamel coating, and also dental erosion, which is caused by acids from both the food we eat and the plaque and tartar that can build up naturally on our teeth.  Gum disease can also cause sensitive teeth, as this can make the gums recede exposing the more vulnerable root area which is much more receptive to pain than the main tooth.  Another cause of tooth sensitivity is grinding your teeth, which is a habit normally triggered by stress and results in grinding and clenching teeth together particularly during sleep which can wear the enamel coating on the teeth away.

If you have a cracked tooth or cavity then you will also most likely experience some tooth sensitivity as the vulnerable root area will be exposed and dental whitening treatments can also cause tooth sensitivity, especially in patients will pre-existing problems with thin enamel and exposed dentine.

Treating Sensitive Teeth

There are a number of toothpaste brands available over the counter which can help to treat sensitive teeth and these work by building up a protective layer over sensitive areas and can take from around a few days to several weeks to take effect.  You can also ask your dentist is there are any other treatments available for sensitive teeth.
