Four Causes of Tooth Sensitivity

July 16, 2013

Tooth sensitivity is a common complaint of dental patients, but there’s no single cause. In today’s post, we’ll detail some of the most common culprits and explain how treatment or prevention might be possible.

Aggressive Brushing

One part of achieving a healthy smile is brushing on a regular basis, but there’s a difference between brushing thoroughly and brushing aggressively. Patients who brush too hard with a hard-bristled brush can damage their teeth and gums, causing sensitivity. To prevent sensitivity caused by aggressive brushing, don’t be afraid to ask Dr. Goldstein of Randolph Dental Care for brushing tips. We’re dedicated to educating our patients and helping them achieve effective daily care.

Teeth Grinding

The medical term to describe a teeth grinding problem is bruxism. Patients who struggle with bruxism grind their teeth unconsciously, often while asleep. Bruxism is triggered by stress and the affliction can seriously damage teeth. Under the right conditions, teeth can even become cracked, making it possible for bacteria to get inside a tooth and exposing the porous layer of dentin beneath the outer layer of enamel. If you struggle with teeth grinding, talk to Dr. Goldstein. Bruxism can be effectively treated with a custom-made night guard.

Gum Recession/Gum Disease

Gum recession is one of the most common causes of sensitivity, which itself is caused by advanced gum disease. As the gums recede, more of the patient’s teeth are exposed, including that crucial layer of dentin. Things that are hot, cold, or acidic can send shockwaves through the dentin to the inner pulp, or the nerve of the tooth. To prevent sensitivity caused by gum recession, see Dr. Goldstein for periodontal therapy at the first sign of gum disease. Treating gum disease early will help you preserve your oral health and protect against sensitivity.


Patients between the ages of 25 and 30 experience more sensitivity than patients of other ages. If you’re in your mid-twenties and have noticed any changes in how sensitive your teeth are, Dr. Goldstein may be able to help.
