Tooth sensitivity can be disheartening: you’re always on your guard with what you eat or drink, and perhaps you’ve even given up on favorite foods or beverages.
The most common cause for this painful sensitivity is dentin exposure caused by receding gums. Dentin contains tiny open structures called tubules that transmit changes in temperature or pressure to the nerves in the pulp, which in turn signal pain to the brain. The enamel that covers the dentin, along with the gum tissues, creates a barrier between the environment and dentin to prevent it from becoming over-stimulated.
Due to such causes as aggressive over-brushing or periodontal (gum) disease, the gum tissues can recede from the teeth. This exposes portions of the dentin not covered by enamel to the effects of hot or cold. The result is an over-stimulation of the dentin when encountering normal environmental conditions.
So, what can be done to relieve painful tooth sensitivity? Here are 3 ways to stop or minimize the symptoms.
Change your brushing habits. As mentioned, brushing too hard and/or too often can contribute to gum recession. The whole purpose of brushing (and flossing) is to remove bacterial plaque that’s built up on tooth surfaces; a gentle action with a soft brush is sufficient. Anything more than two brushings a day is usually too much — you should also avoid brushing just after consuming acidic foods or liquids to give saliva time to neutralize acid and restore minerals to the enamel.
Include fluoride in your dental care. Fluoride has been proven to strengthen enamel. Be sure, then, to use toothpastes and other hygiene products that contain fluoride. With severe sensitivity you may also benefit from a fluoride varnish applied by a dentist to your teeth that not only strengthens enamel but also provides a barrier to exposed dentin.
Seek treatment for dental disease. Tooth sensitivity is often linked to tooth decay or periodontal (gum) disease. Treating dental disease may include plaque removal, gum surgery to restore receded gums, a filling to remove decay or root canal therapy when the decay gets to the tooth pulp. These treatments could all have an effect on reducing or ending your tooth sensitivity.

“We all scream for ice cream,” the saying goes. But what if eating ice cream — or any very cold or hot food — literally makes you want to scream because your teeth hurt so much?
Understanding the anatomy of a tooth helps explain what happens when a tooth becomes sensitive to heat and cold. A tooth is composed of three types of tissue: a hard outer shell of enamel, the body of the tooth composed of the dentin, and an interior tissue of the pulp.
Enamel: The enamel forms the outside of the crown, the part of the tooth you normally see. Made of densely packed crystals of calcium, it is resistant to wear. It is not living tissue, and does not contain nerves, but it is capable of transmitting temperature like hot and cold.
Dentin: Inside the tooth's crown and root is a living tissue called dentin, which is a porous structure similar to bone. It is composed of microscopic tubules containing living cells, which are encased in a hard substance made of calcium crystals.
Pulp: The living dentin transmits sensation through to the pulp, which is in the center of the tooth and contains the tooth's blood vessels and nerves.
A tooth's enamel normally protects the dentin from exposure to extremes of temperature and pressure. If you wear away the enamel and expose the dentin, it will pass sensation through to the nerves in the pulp more directly. The result can range from a twinge to an excruciating pain.
Of course, if the problem is caused by tooth decay, make an appointment with us to remove the decay and place a filling in the sensitive teeth.
