Do your teeth twinge when you eat or drink certain things? You could be suffering from sensitive teeth.

In most cases, the sensation occurs when the fluids within dentine, the soft bit of­ the tooth under the enamel, are affected by hot, cold, sweet or acidic foods or drinks. This triggers your nerve endings to fire with the resulting sensation ranging from a mild tingle to severe discomfort and pain.

Sensitivity is a common dental problem. Usually, sensitive teeth are a short term issue that may arise from brushing too hard, dietary issues or the use of certain dental products, such as teeth whiteners.

Desensitising toothpastes are a great way to treat the problem at home, however if sensitivity is present for a long period of time or causes severe discomfort, it may be time to get to the bottom of this painful condition.

You should consider making an appointment with your dentist if:

• sensitivity is limited and persistent in one tooth or area of the mouth,
• there is no decrease in sensitivity after using at home treatments,
• your gums are discoloured or swollen around the sensitive area, or
• if you have a history of tooth decay, or gum problems.
