Teeth Sensitivity: What Causes It?

Do you ever experience sensitivity or pain when you bite into something too hot or too cold? Are you ever hesitant to talk or smile because you worry about exposing your teeth to the cold? Did you know that regardless of how long you’ve dealt with tooth sensitivity, there may be something you can do to alleviate your discomfort? But before you can address sensitive teeth, you should know what causes it.

One of the most common causes of sensitivity comes from brushing your teeth. More specifically, your teeth can be sensitive if you brush too hard. You may think that you need to brush hard to get all the plaque off your teeth, but this isn’t the case. In fact, you should choose a toothbrush with soft or medium bristles to keep your teeth safe. If you brush too hard for too long, you could wear down your enamel (the outer layer of your teeth). This will expose your dentin—and because dentin is linked to your nerves, exposed dentin leads to sensitivity.

Similarly, your teeth could be sensitive because you grind your teeth. Unfortunately, many people unknowingly grind their teeth while they are sleeping. When you grind, the ligaments that connect your jaw and teeth get inflamed. This aggravates your nerves and makes your mouth more vulnerable to temperature sensitivity.

Fortunately, there are a few things you can do to combat sensitivity. For example, you can change your diet. Particularly, you should have a diet that is high in calcium which will strengthen your teeth. You should also avoid highly acid foods and drinks.

If your problems come from grinding, a dentist can create a custom mouthguard that can stop you from grinding. You should also visit Dr. Swati Agarwal regularly for routine cleanings and checkups.
