Causes of Sensitive Teeth

Tooth sensitivity affects around 1 in 8 adults in the United States. Sensitive teeth can cause pain for people when they drink hot or cold foods and beverages.

In the most basic sense, tooth sensitivity is caused by the outer layer of enamel being worn away from the tooth, exposing the second layer of the tooth, known as the dentin.

That is a basic explanation, but what causes the outer layer of enamel to wear away from your teeth? In this post, we will list some of the root causes of sensitive teeth.

Using a toothbrush with hard, stiff bristles

Brushing too hard with a very stiff toothbrush can wear away your tooth enamel over time. It can even cause your gums can pull away from tooth roots. It is not necessary to brush your teeth so hard. Gently brushing your teeth is effective enough and won’t damage your enamel

Overuse of acidic mouthwash

Sometimes people can be too enthusiastic about using mouthwash. Some mouthwashes and rinses may contain alcohol and acidic compounds that can make already-sensitive teeth worse.Try limiting your rinsing to once or twice a day or skip the mouthwash and be better about flossing instead.

Worst Foods for your Teeth

Eating too many acidic foods

Eating too many acidic foods such as tomatoes, citrus fruits and juices can wear away at your enamel. Besides cutting down on the amount of them you consume, you can try cutting the acid in your mouth with a piece of cheese or glass of milk after eating.

Using a tooth whitening toothpaste

Many special teeth whitening kinds of toothpaste can have chemicals that may cause sensitivity in people. You may need to switch to one without whitening agents or ask your dentist for a recommendation.

Grinding your teeth

Over time, grinding or clenching your teeth can wear down your outer layer of enamel, causing tooth sensitivity.

Receding Gums

The roots of your teeth are usually covered by a layer of gum tissue. If you have periodontal disease, the gums can begin to recede away from the root of the tooth and expose the sensitive part of your teeth, resulting in a sensitivity to temperatures.

Recent dental work

Teeth cleanings, replacement crowns, tooth restorations, and root planing can all cause tooth sensitivity. These should only be temporary until your teeth have had time to recover. If it doesn’t go away, call your dentist to make sure there is not an infection.
