Can sensodyne help with sore teeth?

Yes: If cold water/air etc make your teeth sensitive then sensodyne will help.

Sometimes.: Depending on the reason for the soreness, solutions vary. Sensodyne makes a number of different products all intended for different specific applications; one of these may work for you. If the soreness persists, ask your dentist to evaluate it and help you find a solution to your specific condition :).

Sensodyne: It depends on what you mean by soreness. If you are tallking about a toothache soreness then no toothpaste will likely help with this as it is a sign of a bigger problem. If you are talking about sensitivity to temperatures, or touching the tooth where the tooth meets the gum then strontium chloride or potassium nitrate is found in sensodyne has been shown to reduce sensitivity.
