Sensitive teeth can be a problem, but there are ways to tackle the issue.

Millions of people suffer from sensitive teeth every day and the problem can be very severe and impact on quality of life for sufferers.

However, the Hindu Times reported 46 per cent of people who suffer from sensitive teeth are aged between 30 and 40, but there is very little awareness of the fact that desensitising toothpastes are now available.

The toothpastes work by filling small channels in the dentine of teeth that lead directly to the nerve endings. When this dentine is exposed and comes into contact with cold substances, the heat transfer can cause the nerve to fire creating pain.

Elsewhere, dietician Elaine Hastings recently claimed children should eat a healthy mix of foods in order to keep their teeth as strong as possible.

She noted drinking lots of milk is important, as the calcium contained in the drink is needed – especially when children’s teeth are developing – to ensure enamel stays strong.
