Examination
We identify which teeth are sensitive and examine them for decay, cracks, gum recession, and enamel wear.

Tooth sensitivity
My Tooth Is Sensitive
Tooth sensitivity is one of the most common dental complaints — and one of the most treatable. You don't have to live with pain every time you eat or drink.
What is this condition?
Tooth sensitivity is a sharp, sudden pain or discomfort triggered by hot, cold, sweet, or acidic foods and drinks — or sometimes just cold air. It occurs when the inner layer of the tooth (dentin) becomes exposed, allowing stimuli to reach the nerve. Sensitivity can affect one tooth or many, and it ranges from mild to severe.
Why might I have this?
- Enamel erosion from acidic foods and drinks
- Gum recession exposing the sensitive root surface
- Teeth grinding (bruxism) wearing down enamel
- A cracked or chipped tooth
- Tooth decay or a cavity
- A loose or failing filling
- Gum disease causing the gum to pull away from the tooth
- Temporary sensitivity after dental treatment (normal and resolves on its own)
What symptoms should I watch for?
- Sharp pain when eating or drinking hot or cold foods
- Pain when eating sweet or acidic foods
- Discomfort when breathing cold air
- Sensitivity that lingers for more than a few seconds after the trigger is removed
- Pain localized to one specific tooth (may indicate a cavity or crack)
- Sensitivity that is getting progressively worse
What happens during treatment?

X-Rays
X-rays help us rule out decay, infection, or other underlying causes that may be contributing to sensitivity.
03
Diagnosis
We determine the cause of your sensitivity and recommend the most appropriate treatment.
04
Treatment
Options include desensitizing agents, fluoride treatments, bonding to cover exposed roots, a night guard for grinding, or treatment of any underlying decay or gum disease.
Will it hurt?
Most sensitivity treatments are painless. If a filling, crown, or other restoration is needed, we will use local anesthesia to ensure your complete comfort.
How long does it take?
A sensitivity evaluation takes 30–45 minutes. In-office desensitizing treatments are quick — often completed in the same appointment. More complex treatments (fillings, crowns) require additional time.
What happens after treatment?
- Use a soft-bristled toothbrush and brush gently
- Use a sensitivity toothpaste containing potassium nitrate or stannous fluoride
- Avoid highly acidic foods and drinks (citrus, soda, vinegar)
- Wear a night guard if grinding is a factor
- Attend regular cleanings to prevent gum recession from worsening
What happens if I don't treat it?
Sensitivity that is caused by decay or a crack will worsen over time. What starts as mild sensitivity can progress to severe pain, infection, and the need for a root canal or extraction. Sensitivity caused by gum recession will continue to worsen as the gum tissue recedes further.
Possible treatments
Preventive Care
Fluoride treatments and sealants strengthen enamel and reduce sensitivity.

Restore teeth damaged by decay or cracks that are causing sensitivity.

When sensitivity is caused by an infected nerve, a root canal eliminates the pain.
Learn moreNight Guards
Custom night guards protect enamel from grinding-related sensitivity.
