Sensitive teeth are a widely common condition seen mostly in people of twenty to forty-five years. Women are more likely to be prone to sensitive teeth when compared to men. It can start at any point in your life and can be pretty devastating to deal with in day to day life. Each tooth is protected by a layer of enamel that protects the dentine texture beneath. If this particular dentine texture is affected by the loss of enamel that covers it, then the tooth becomes sensitive.
