Brunette man cringes in pain and touches his cheek due to sensitive teeth

Tooth sensitivity is characterized by aching discomfort or shooting pain in the teeth. Foods and drinks that are hot, cold, sweet, and/or sour can trigger it. Your teeth may even feel sensitive if you breathe in through your mouth on a cold day! There are a few possible reasons why your teeth may feel sensitive:

Cracked or Chipped Tooth

If sensitivity feels localized to a specific tooth, it’s possible you cracked or chipped it. Breaks can expose the nerves inside a tooth so any contact with triggering sensations will hurt more than usual. It’s important to see a dentist as soon as possible! Bacteria can get inside a cracked tooth and cause an infection.


Cavities form when the acid from bacteria erodes holes in your teeth. This weakens your enamel and increases sensitivity. You can prevent cavities by maintaining great oral hygiene at home and visiting us for cleanings every six months!

Teeth Grinding & Clenching

Grinding and clenching your teeth wears down your tooth enamel. When your enamel is thinner, the nerves inside a tooth are more vulnerable. Teeth grinding can be a cause or result of TMJ dysfunction, which treatments like BOTOX and TMJ therapy can help with.

Gum Desease

Gum disease can result in your gums pulling away from your teeth, exposing the sensitive tooth roots. Other warning signs include swelling, tenderness, and bleeding. If you have any of these symptoms, you should improve your oral hygiene routine and make an appointment with a dentist for a diagnosis.
