Dr. Mahmoud Abu Zainah – Teeth Sensitivity

Teeth sensitivity can occur when you consume hot, cold, sweet or sour foods and drinks. Pain can be sharp, sudden and shoot deep into tooth nerve endings. Treatments include fluoride, desensitizing toothpaste and dental bonding.

What is teeth sensitivity?

Teeth sensitivity usually occurs when the underlying layer of your teeth — the dentin — becomes exposed. This can happen due to erosion (wear and tear) and gum recession (when your gum tissue pulls away from your teeth, exposing the roots).

Dental sensitivity can also be a symptom of other issues, including cavities, gum disease or a cracked tooth.

What causes sudden tooth sensitivity?

  • Brushing too hard
  • Gum recession
  • Gum disease: Inflamed and sore gum tissue
  • Cracked teeth
  • Teeth grinding: Grinding or clenching your teeth may wear down the enamel and expose underlying dentin.
  • Acidic foods: Regular consumption of foods with a high acid content, such as citrus fruits, tomatoes, pickles and tea, can cause enamel erosion.
  • Recent dental procedures can get sensitive teeth after fillings, teeth cleanings and dental restoration placement.

How do you stop sensitive teeth pain?

Treatment depends on the cause.

To reduce your risk of teeth sensitivity caused by normal wear and tear:

  1. Use desensitizing toothpaste: There are several brands of toothpaste for sensitive teeth. With regular use, you should notice a decrease in sensitivity.
  2. Maintain good oral hygiene: Continue to follow proper brushing and flossing techniques to thoroughly clean all parts of your teeth and mouth.
  3. Use a soft-bristled toothbrush: This will result in less toothbrush abrasion to the tooth surface and less irritation to your gums.
  4. Watch what you eat: Frequent consumption of highly acid foods can gradually dissolve tooth enamel and lead to dentin exposure. They may also aggravate the sensitivity and start the pain reaction.
  5. Use fluoridated dental products: Daily use of a fluoridated mouth rinse can decrease sensitivity. Ask your dentist about available products for home use.
  6. Avoid teeth grinding: If you grind or clench your teeth, use a mouth guard at night.
  7. See your dentist regularly: Get routine professional exams, cleanings and fluoride treatments.
