If a mouthful of ice cream or a sip of hot tea makes a person wince, it is likely that they are suffering from sensitive teeth. Normally, teeth are not sensitive, but when enamel is worn away or gums recede, the underlying layer of dentine can become exposed. When stimuli such as hot or cold food and drink comes into contact with the exposed nerve endings inside the teeth, the result is the sudden, sharp pain associated with sensitivity. Common causes of sensitive teeth include:  

• Tooth decay
• A tooth which is cracked, chipped or worn
• Worn or cracked fillings

Tooth roots which are exposed as a result of receding gums or gum disease. Frequent consumption of acidic drinks, incorrect tooth brushing technique and brushing teeth with a very abrasive toothpaste can also lead to the loss of tooth enamel. Sensitive teeth can be treated €“ decayed teeth can be filled, and worn or cracked fillings replaced. Sufferers can also opt to use a special toothpaste for sensitive teeth (e.g. Sensodyne, Colgate Sensitive). Using a mouthwash for sensitive teeth (e.g. Listerine Advanced Defence Sensitive, Oral-B Sensitive Mouthrinse, Sensodyne Gentle Mouthrinse) may also help.
