Why do teeth become so sensitive?

There are several reasons why teeth become sensitive. These reasons can be divided into external and internal causes.

External causes:

* Tooth decay: When bacteria damage the enamel on your teeth, it can expose the dentin underneath, which is a porous material that contains tiny tubules. These tubules lead directly to the nerve center of your tooth, making them highly sensitive to hot, cold, sweet, or sour foods and drinks.

* Gum recession: As you age, your gums may recede, exposing the roots of your teeth. The roots of your teeth are not covered in enamel, so they are more sensitive to stimuli than the crowns of your teeth.

* Poor oral hygiene: If you don't brush and floss your teeth regularly, plaque and tartar can build up on your teeth. This buildup can irritate your gums and cause them to recede, exposing the roots of your teeth.

* Grinding your teeth (bruxism): Grinding your teeth can wear down the enamel on your teeth, making them more sensitive.

Internal causes:

* Dental work: Dental procedures such as fillings, crowns, and root canals can irritate the pulp of your tooth, causing sensitivity.

* Certain medications: Some medications, such as antidepressants and antihistamines, can cause dry mouth, which can lead to increased tooth sensitivity.

* Medically compromised: People who have certain medical conditions, such as diabetes or an autoimmune disorder, may be more likely to experience tooth sensitivity.

Your dentist can help you determine what the best way to relieve tooth sensitivity is.

Preventing tooth sensitivity:

There are several things you can do to help prevent tooth sensitivity, including:

* Brushing your teeth twice a day with a soft-bristled toothbrush and a toothpaste for sensitive teeth.

* Flossing your teeth once a day.

* Avoiding sugary foods and drinks.

* Drinking plenty of water.

* Seeing your dentist regularly for checkups and cleanings.

* Wearing a nightguard if you grind your teeth.
