    Sensitive teeth


    Sensitive teeth can be anything from getting a mild twinge to severe discomfort which can last for several hours. Having sensitive teeth can be a sign of more serious dental problems.

    What we can see out of our teeth is 1/3 of the actual teeth which is above the gum line and  this part is covered by a white layer called enamel that protects the sensitive dentine underneath. If  dentine is exposed, a tooth can become sensitive and the more enamel is abraded the more sensitive is the tooth/teeth .

    Causes of sensitivity.

    Hard toothbrush – Brushing too hard, and brushing from side to side, can cause enamel to be worn away, particularly at the area where  teeth meet the gums and the deeper it is the more sensitive is the tooth.

    Acids –  Attack from acidic food or drinks or even from stomach leads to dentine exposure which may lead to sensitivity.

    Gum recession – Gums may naturally recede , and roots will be exposed. Root surfaces do not have an enamel layer to protect them.

    Gum disease – A build-up of plaque or tartar on and in between teeth can irritate and destroy the bony support of the tooth causing gum to recede and roots exposure.

    Teeth grinding – This is a habit which involves clenching and grinding teeth together. which can remove the enamel . Other causes :

     Cracked tooth or filling – a crack can run from the biting surface of a tooth down towards the root. Also removed filling can cause sensitivity as well.

     Teeth bleaching – Some patients have sensitivity for a short time during or after having their teeth bleached.

    When do you feel sensitively?

    when drinking or eating something cold, from cold air or even from air condition, and sometimes with hot foods or drinks. Some people have sensitivity when they have sweet or acidic food and drink. The pain can come and go, and some times being worse than others.


     Treatment at home?

    Many brands of toothpaste for sensitive teeth available in the market can ease the pain of sensitive teeth. Use the toothpaste twice a day to brush your teeth, but  make sure to keep the past in the mouth after brushing for at least 1-2 minutes. You can also try rubbing it onto the sensitive areas. It may take anything from a few days to several weeks to have effect. Your dentist is the only person to advise you on the proper tooth paste. And , if you have tried treating your sensitive teeth for a few weeks and have had no improvement go to your dentist.

    If you have teeth sensitivity- Avoid:

    Any thing  gives you sensitivity you should avoid it can be hot, cold, sweet, acidic drinks, or  ice cream . It is important you do not avoid brushing your teeth regularly as this could make the problem worse.

    How can to prevent sensitive teeth?
