Many adults suffer from sensitive teeth or dentine sensitivity. In the UK over 20mllion people suffer from it. This condition is common when enamel covering the crown of the tooth is worn away and the root surfaces of teeth are exposed. The main causes are increases in gum recession and toothbrush abrasion due to inappropriate tooth brushing techniques.
The main core of the tooth consists of many tubules running from the outer edge of the tooth to its inner center which contains the tooth nerve. These tubules contain fluid which when exposed move under the influence of the cold or heat and stimulate the nerve, causing pain and discomfort.
To treat sensitive teeth you should use toothpaste that is designed to work with sensitive teeth. These toothpastes can take around 3 weeks to take affect.
