Your teeth might be sensitive if the tooth dentin is exposed because of : tooth decay, gum disease and recession, tooth grinding.

Dentin is the material that makes up the part of the tooth below the gums,the root, and is found under the enamel layer. It is a much softer material than enamel.

When this material is exposed to the air, cold, acidic drinks or infected with decay, the tooth may exhibit signs of discomfort.

What can be done to relieve the discomfort?

• Use a desensitizing toothpaste and fluoridated dental products. Visit Canadian Dental Association's website, www.cda-adc.ca, and look on the CDA Seal of Recognition page for a list of recommended desensitizing products.
• Use a soft toothbrush and brush gently using a circular motion.
• Reduce your intake of acidic foods and sugary snacks and drinks.
• Discuss options of bonding (more permanent fix where an insulating layer of tooth-coloured composite resin is applied to exposed, sensitive roots) and application of in office fluoride varnish.
• If grinding your teeth at night has caused tooth enamel to wear away, your dentist might suggest making you a close-fitting, thermoplastic nightguard to protect your teeth while you sleep.

See your dentist at once if:

• Your teeth are also sensitive to pressure.
• Your teeth sensitivity doesn't decrease after using a desensitizing toothpaste for a few weeks.
• The pain from tooth sensitivity lasts longer than one hour.
• The gums around your sensitive teeth appear to be changing colour.
