You can experience tooth sensitivity for various reasons—some serious, some not so serious. However, if you notice ongoing tooth sensitivity or if it increases, we recommend contacting your Brentwood, TN dentist to schedule a checkup.

Causes of Tooth Sensitivity

The most common causes of tooth sensitivity include:

  • Aggressive brushing
  • After dental work (temporary)
  • Tooth or gum infection and decay
  • Bruxism
  • Periodontal disease

Aggressive Brushing

Your dentist near me recommends a soft-bristled toothbrush. You should brush every tooth gently to the gumline, taking care to clean all surfaces. It is not necessary to “scrub” with your toothbrush. Instead, use a gentle circular motion.

After Dental Work (Temporary)

In some cases, you may experience sensitivity following dental treatments, including professional teeth whitening. But this is temporary and should resolve within a few days. If it does not, please let us know, and we will get you taken care of.

Tooth or Gum Infection and Decay

A deep root infection or decay often causes tooth sensitivity that can escalate to severe pain without treatment. If you notice tooth sensitivity or pain, a blister on the gum, or other oral health changes, we encourage you to call our dental office as soon as possible.


Bruxism is a sleep habit that causes you to grind and clench your teeth. Symptoms can include headache, neck pain, shoulder pain, jaw, and toothaches. Without treatment, you can wear away your tooth enamel, which may lead to sensitivity. Your dentist may recommend a nightguard to prevent bruxism destruction.

Periodontal Disease

Periodontal disease can cause many symptoms, including bad breath, tooth and gum pain, loose teeth, and even body health issues. Tooth sensitivity is a common association. Periodontal disease needs treatment to save your smile and your wellness.
