Does the taste of cold ice cream or a sip of hot coffee cause a painful experience for you? Does brushing or flossing make you wince occasionally? If so, you may have sensitive teeth.
In healthy teeth, a layer of enamel protects the crowns of your teeth—the part above the gum line. Under the gum line a layer called cementum protects the tooth root. Underneath both the enamel and the cementum is dentin.
Dentin is less dense than enamel and cementum and contains microscopic tubules (small hollow tubes or canals). When dentin loses its protective covering of enamel or cementum these tubules allow heat and cold or acidic or sticky foods to reach the nerves and cells inside the tooth. Dentin may also be exposed when gums recede. The result can be hypersensitivity.
Possible causes include:
- Tooth decay (cavities)
- Fractured teeth
- Worn fillings
- Gum disease
- Worn tooth enamel
- Exposed tooth root
Sensitive teeth can be treated. The type of treatment will depend on what is causing the sensitivity.
Your dentist may suggest one of a variety of treatments:
- Desensitizing toothpaste. This contains compounds that help block transmission of sensation from the tooth surface to the nerve, and usually requires several applications before the sensitivity is reduced.
- Fluoride gel. An in-office technique which strengthens tooth enamel and reduces the transmission of sensations.
- A crown, inlay or bonding. These may be used to correct a flaw or decay that results in sensitivity.
- Surgical gum graft. If gum tissue has been lost from the root, this will protect the root and reduce sensitivity.
- Root canal. If sensitivity is severe and persistent and cannot be treated by other means, your dentist may recommend this treatment to eliminate the problem.
To prevent sensitive teeth from recurring, your dentist might offer suggestions to help you maintain your oral health. Twice a day, brush your teeth with a soft-bristled toothbrush and fluoride toothpaste. Floss daily. Avoid vigorous or harsh scrubbing, highly abrasive toothpaste, and excessive brushing and flossing. If you grind your teeth, ask your dentist about a mouth guard. Grinding your teeth can fracture your teeth and cause sensitivity.
Proper oral hygiene is the key to preventing sensitive-tooth pain.
