Common Causes of Sensitive Teeth

Teeth sensitivity can happen to anyone. Exposed roots or eroded enamel often cause teeth sensitivity. However, teeth can get sensitive because of many other reasons as well. We have mentioned some of the common causes of sensitive teeth below.


Teeth whitening

Several people opt for teeth whitening to remove discoloration and surface stains for a whiter smile. Still, what they may not understand is that those whitening procedures can also bring teeth sensitivity. Peroxide, which is among the main ingredients in several teeth whitening products, can irritate your teeth's nerve.


Brushing too hard

If you brush hard or use a toothbrush that contains stiff bristles, they can wear out the enamel on your teeth and cause the dentin to get exposed. Brushing hard can lead to gum recession and root exposure as well. This is the reason several dentists suggests that you use a soft-bristle toothbrush.


Irregular flossing

Like brushing your teeth a minimum of twice a day, flossing is an essential part of your dental hygiene. Flossing stops plaque from developing on your teeth. This decreases the chances of gum disease, teeth sensitivity, and receding gums.



Demineralization happens when the mineral content in the teeth enamel reduces. When the enamel begins to break down, teeth get more sensitive, and it is easier for plaque to infect the teeth's vulnerable interior. The enamel is not a developing tissue; it cannot be restored or regenerated once it is gone. Acidic foods and sugary drinks are the major demineralization's cause, so it is better to avoid them as much as possible.


Teeth grinding

Do you find yourself grinding your teeth in the day or getting up in the morning with a sore jaw? Teeth grinding can wear away your teeth or possibly even crack or chip the teeth. It also causes enamel damage and exposes the dentin's inner layer. This makes your teeth more susceptible to sensitivity and decay.



Your diet can play a major role in your sensitive teeth. Frequently eating acidic foods and acidic drinks, like pickles, tomatoes, tea, and citrus fruits, can cause enamel to erode, which increases teeth sensitivity.


Solutions for Sensitive Teeth

While several factors can cause sensitive teeth, the bright side is that various dental procedures can protect sensitive teeth. If you have sensitive teeth, your dentist might suggest trying one of the solutions mentioned below.


Dental sealants

Dental sealants are a thin resin coating that a dentist paints on your teeth to help decrease sensitivity. It is essential to remember that dental sealants are a temporary solution, and they will eventually wear off.



If teeth grinding, also called bruxism, makes your sensitive teeth, your dentist may suggest that you wear a mouthguard while sleeping at night. You can buy mouth guards that you mold at home. Your dentist can create your teeth's mold and make a custom-fitted mouthguard. A mouth guard help decrease sensitive teeth' pain. It can also remove any pain in the jaw joint and reduce headaches.


Fluoride varnish

Fluoride varnish or gel is a highly concentrated form of fluoride. Your dentist applies fluoride on your teeth to decrease some teeth sensitivity's pain, and discomfort. Fluoride varnish can help strengthen your dentin and enamel.


Bonding agent

If you get sensitive teeth because the teeth' roots are exposed, your dentist may recommend utilizing a bonding agent to cover the surface of the root. For this form of treatment, your dentist applies the bonding agent on the exposed root to block its exposure and decrease your pain.


Root Canal

If the above choices do not work and your sensitive teeth decrease your quality of life, your dentist may suggest a root canal. Your dentist will take out the pulp or soft nerve tissues within your tooth at a root canal. It will eliminate the discomfort and pain caused by the tooth.


Tooth sensitivity is a prevalent problem that several people face. Now that you know some common causes and solutions to sensitive teeth, you can speak with your dentist today to get treated.
