Some people's teeth are more sensitive to cold, often near the gumline. This can happen for a lot of different reasons.
Sometimes people are simply more sensitive to cold and hot temperatures.
Other causes may be recession of the gum tissue, abrasions of the teeth, large metal restorations, or decay. Sometimes the outer protective layers of the tooth become worn, and the exposed dentin becomes sensitive. There can also be increased sensitivity if a filling has been lost or has become loose or the tooth root has become exposed due to gum recession.
There are many ways to treat tooth sensitivity. Some range from simple changes you can make at home, and others will involve some time in the dental chair. But the good news is that you should be able to do something about tooth sensitivity. Here are some of the possibilities for treatment:
- Brushing with toothpaste that is specifically made for sensitive teeth
- Applying fluoride treatments either at home or in the office
- Changing your diet to avoid the triggers for sensitivity
- Covering an exposed area of the tooth with crowns or fillings
- Using grafting to cover receding gum areas
- Treating an infection or severe decay with root canal therapy
