Sensitivity to Hot and Cold Drinks and Foods

Ever taken a sip of your favourite warm or cold drink and felt a jolt of pain in your teeth? You have sensitive teeth. Here’s what you need to know!

What causes tooth sensitivity?

In the vast majority of cases, the cause of sensitive teeth is very simple: Your dentine is being exposed. Dentine is the “inner” layer of your tooth; it sits underneath the enamel, the outer layer, and has countless microscopic tubes leading to the nerve in the centre of your tooth.

Hot and cold drinks and foods will then reach the exposed dentine, travel through the tubes and stimulate the nerve in your tooth, causing you pain.

The most common causes of exposed dentine are enamel erosion and receding gums, both of which can be prevented through a thorough dental health routine, brushing correctly and flossing regularly.

Overbrushing – brushing too hard, for too long, with a hard toothbrush – is particularly hard on your enamel, and will contribute to scrubbing your enamel right off your teeth.

Other common ways to damage enamel include food and drinks with high acid or sugar content, and overuse of teeth bleaching agents.

What can you do?

If your teeth always hurt when you drink cold or warm drinks, you should make an appointment to see a dentist. It’s important that you do this as soon as you notice discomfort with hot and cold drinks because it’s easier for us to treat the earlier it is discovered.

Sensitive teeth can sometimes also be caused by a cavity or an infected dental pulp, which will require immediate professional attention

Only a qualified dentist will be able to treat the symptoms problems associated with exposed dentine. Solutions include simply applying temporary bonding to protect the exposed dentine, and a full root canal, removing the inner pulp and nerve of the tooth.
