Why are my teeth so sensitive when I brush them or drink something cold?
If you have sensitive teeth, it could be for the following reasons:
- Your tooth enamel has become worn down. This can be because you are using a hard-bristled toothbrush or brushing too aggressively.
- Your teeth might be eroded from foods and beverages that are high in acid.
- You might have a cavity, a broken tooth, or an old filling that is leaking, all of which can expose the dentin portion of the tooth.
- Your gums have receded and your tooth root is exposed.
- You might be grinding your teeth at night.
If you have recently had dental work done, such as a filling or crown, or you have undergone teeth whitening, this can cause sensitivity although it is usually temporary.
You can decrease tooth sensitivity by protecting your enamel. Use a soft-bristled toothbrush and make sure you are not brushing too hard. There are several desensitizing toothpastes on the market that can also help decrease sensitivity. We can also provide a fluoride treatment or application of a desensitizing agent after cleaning to help.
