Tooth sensitivity is a painful reaction to hot, cold, sweet, or sour foods and drinks. This pain can be sharp, sudden and shoot deep into the nerve endings of your teeth.
Apart from a cavity or a missing filling, the most common cause of tooth sensitivity is an area of the root of your tooth that has become exposed.
Exposed root surfaces can be caused by:
- Brushing too hard
- Recession of the gums
- Gum disease
Other causes of sensitive teeth:
Grinding your teeth – Grinding or clenching your teeth may wear down the enamel and expose underlying dentin.
What to do at home:
- Maintain proper oral care habits
- Use a soft bristled toothbrush
- Use desensitizing toothpaste
- Use a fluoridated mouth rinse
- Avoid acidic foods, such as lemons
Ask your dental hygienist about professional products that may be used to help reduce sensitivity.
Some of the most common professional treatments used are:
- White fillings to cover exposed root surfaces
- Fluoride varnishes applied to the exposed root surfaces
- Dentin sealers applied to the exposed root surfaces
