Sensitive Teeth
Is the taste of ice cream or a sip of hot cocoa sometimes a painful experience for you? Does brushing or flossing make you wince occasionally? If so, you may have sensitive teeth.
Possible causes include:
- Tooth decay (cavities)
- Fractured teeth
- Worn fillings
- Gum disease
- Worn tooth enamel
- Exposed tooth root
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 cementum is dentin.
Dentin is less dense than enamel and when it looses the protective covering of enamel, it allows heat and cold or acidic or sticky foods to reach the nerves inside the tooth. Dentin may also be exposed when gums recede. This can result in sensitive teeth.
Sensitive teeth can be treated. The type of treatment will depend on what is causing the sensitivity.
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.
Crown. 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 cannot be treated by other means, your dentist may recommend this treatment to eliminate the problem.
Proper oral hygiene is the key to preventing sensitive-tooth pain. Ask your dentist if you have any concerns about your daily oral hygiene routine or concerns about tooth sensitivity.
