Do you have occasional sensitivity to cold in your teeth?

Well, it could be a problem with a cavity, filling, cracked tooth, or just exposed dentin. How do you tell which it is? If you have had us look at your teeth in the last 6 months or so, you most likely can rule out the cavity or filling problem. A cracked tooth can hurt to cold, but it usually hurts primarily to chewing.

Dentinal hypersensitivity (sensitive root) is caused when the enamel or gum disappears and the underlying dentin is exposed. This exposed dentin is caused by tooth brushing, wear, or acid erosion. Sometimes the problem is aggressive enough to cause a notch in the tooth. Surprisingly the size of the notch is not related to the level of sensitivity. I have seen people with severe dentin sensitivity even when the dentin is barely visible.

The good news is that you can help reduce the sensitivity quite easily, without paying me to fix it. First, avoid acidic foods that will strip off the protective enamel or surface of the tooth. Examples of these are: pineapple juice, tomatoes, lemons, and lemonade. Sour candies are the worst! Examples are: Sour Patch Kids, Sweet Tarts, Jolly Ranchers, Spree, and Tangy Taffy. Secondly, use a desensitizing tooth paste. There are many brands out there and the all work. My favorites are Aquafresh sensitivity, Crest sensitivity, and Colgate Sensitivity. They all contain the active ingredient: potassium chloride. Avoid tarter control tooth pastes that contain sodium pyrophosphate. This chemical will make your teeth even more cold sensitive.

There you go! Watch the acidic foods and use a desensitizing toothpaste for a pain free ice cream cone.
