Sensitive Teeth
Are your teeth sensitive to ice cream or hot coffee? Is brushing your teeth a painful experience? Sensitivity may be caused by cavities, fractured teeth, worn tooth enamel, an exposed root or a cracked tooth.
Underneath the enamel is the dentin and pulp. The dentin contains microscopic tubules (small hollow tubes or canals). When the dentin loses its protective covering, the tubules allow heat and cold or acidic foods to stimulate the nerves and cells inside the tooth. This causes hypersensitivity and occasional discomfort. This irritation does not cause permanent damage to the pulp.
Proper oral hygiene is the key to preventing gums from receding and causing sensitive tooth pain. If you brush your teeth incorrectly or even over brush, gum problems can result.
Dr. Shaw may recommend that you try a desensitizing toothpaste, which contains compounds that help block transmission of sensation from the tooth surface to the nerve. Desensitizing toothpaste usually requires several applications before the sensitivity is reduced.
