Once this outer protective layer is removed (either through decay, excessive
brushing, etc.), pain-transmitting tubules in the exposed dentinal layer
come in contact with the outside environment of the mouth. Thus, changes in
the oral environment, such as temperature and sweetness, are perceived
as pain. It's interesting to note that the nerves in your teeth only
transmit pain.
Causes of Tooth Sensitivity
- Brushing too hard - Over time, brushing too hard or using a hard-bristled toothbrush may cause excessive wear of your enamel and/or cementum, causing dentin to become exposed.
-
Gum disease - Inflamed and sore gums may cause sensitivity due to loss of supporting tissues and the resulting exposure of root surfaces.
- Gum recession - Movement of the gums away from the tooth due to periodontal disease will expose root surfaces.
-
Cracked teeth - Chipped or broken teeth may fill with bacteria and plaque resulting in decay and pain.
- Grinding your teeth - Grinding or clenching your teeth may wear down the enamel and expose underlying dentin.
-
Plaque - The presence of plaque on the root surfaces can cause sensitivity.
Home Care
Maintain Good Oral Hygiene - Continue to clean all surfaces of your teeth and mouth thoroughly. Use a soft-bristled toothbrush. This will result in less abrasion.
Use a Desensitizing Toothpaste - There are a number of desensitizing toothpastes on the market. With regular use you should feel decreased sensitivity in about two weeks. However, the sensitivity usually returns when you stop using the product.
Reconsider Your Diet - If you frequently eat foods high in acids, such as citrus fruits, you may be aggravating your tooth sensitivity. The acids found in citrus will gradually dissolve the protective outer layer of your teeth.
Use Fluoridated Dental Products
Professional Care
