Sensitivity to hot, cold, sugary or acidic foods is common but what causes this pain and how can it be treated?

Our teeth are covered by a layer of hard enamel that protects the softer dentine underneath. If the dentine is exposed this can cause sensitive teeth – usually where the tooth meets the gum and the enamel is thinner. There are a number of reasons why this might be the case including; Toothbrush Abrasion resulting in the enamel being worn down; Dental Erosion where the enamel has been worn down as a result of acid attack; naturally occurring Gum Recession exposing unprotected areas below the original gum line; Gum Disease which also causes the gums to recede; or Tooth Grinding that has resulted in the enamel being worn down. Additional causes of tooth sensitivity might be a Cracked Tooth or Filling or Tooth Bleaching that can sometimes result in sensitivity either during or after the treatment – your dentist should go over this with you prior to any whitening treatment. 

Does bad dental hygiene contribute to sensitive teeth?

Bad dental hygiene is one of the main causes as it can lead to receding gums, gum disease and loss of enamel. As well as brushing incorrectly, excessive brushing and the use of an over-abrasive toothpaste can contribute. Acidic drinks such as pop or even healthy fruit juices can also attack the enamel and tooth grinding and chipped teeth may expose the dentin.

What can I do to treat sensitive teeth?

The first step to rectifying the problem is to consult with a dental professional to establish the cause and agree the best solution.

A good brushing technique and using proper equipment should be things you do as a matter of course but, if not, these will help –use a suitable toothbrush which should be changed at least every 3 months and a toothpaste specially formulated to help reduce sensitivity. There are a number of toothpastes that are readily available for the treatment of sensitive teeth and about which your dentist can advise you – use these at least twice a day when brushing (they can also be rubbed onto the affected area). It may take anything from a matter of days to a few weeks to see results.

Avoid too many acidic drinks and try and remember to consume them with a meal and leave an hour before brushing as the enamel remains soft for this time.

Your dentist may also recommend other treatments such as fluoride gels, rinses or varnishes to give your teeth additional protection. Failing this it may be necessary to seal or fill the exposed dentine and in extreme cases root-filling may be needed.
