Tooth sensitivity is a sharp, short pain from cold, heat, sweets, or brushing. It usually happens when the inner layer of the tooth, called dentin, is exposed. Common causes are worn enamel, gums that have pulled back, a cavity, a cracked tooth, or recent whitening. Most sensitivity improves with the right toothpaste or a simple treatment. Have it checked if it lasts more than a few weeks or centers on one tooth.
Common causes and fixes.
| Cause | Clues | What usually helps |
|---|---|---|
| Gums pulling back | Sensitivity near the gumline; teeth look longer | Sensitivity toothpaste, fluoride, bonding over the root, gum care |
| Worn enamel | Several teeth; acidic drinks or hard brushing | Soft brush, sensitivity toothpaste, fluoride |
| Cavity or old filling | One tooth; sweets set it off | A filling |
| Cracked tooth | Pain when biting or letting go | Bonding or a crown |
| Recent whitening or filling | Started right after treatment | Usually fades within days to a few weeks |
| Clenching or grinding | Flat, worn edges; sore jaw in the morning | Ask us about protecting your teeth |
What you can try at home.
- Use a sensitivity toothpaste twice a day for two to four weeks. Spit, but don’t rinse.
- Brush gently with a soft brush. Scrubbing hard wears gums and enamel.
- Limit soda, sports drinks, and citrus, or drink them with a straw.
- Wait about 30 minutes after acidic food or drinks before you brush.
- Keep brushing and flossing. Skipping them makes things worse.
When to have it checked.
- The pain is in one tooth.
- Pain lingers more than about 30 seconds after cold or heat.
- It hurts to bite.
- You notice swelling or a bad taste.
- Sensitivity toothpaste hasn’t helped after a few weeks.
- Exam
We test the sensitive area and check gums, fillings, and bite. New patient? See your first visit.
- Find the cause
Photos and x-rays show whether it is a cavity, crack, worn enamel, or gum recession.
- Simplest fix first
Often a fluoride treatment or toothpaste change. Sometimes a small filling or bonding.

Check my coverageCommon questions
Why are my teeth suddenly sensitive?
Sudden sensitivity can come from a new cavity, a crack, a lost filling, recent whitening, or gum irritation. If it centers on one tooth or doesn’t fade, have it checked.
Does sensitivity mean I have a cavity?
Not always. Worn enamel and gum recession are common causes too. An exam is the only way to know.
Does sensitivity toothpaste really work?
For many people, yes. It works slowly, so use it twice a day for two to four weeks before judging, and don’t rinse right after brushing.
Can whitening make my teeth sensitive?
Yes, for a short time. It usually fades within a few days. Read more on our teeth whitening page.
Is sensitivity to heat a bigger concern than cold?
Pain from heat that lingers can be a sign the nerve is inflamed. Call us if hot drinks cause pain that lasts. See toothache.
Can gum recession be fixed?
We can often cover and protect exposed roots with bonding and treat the cause, like hard brushing or gum disease. Some cases need a gum specialist. We’ll tell you which applies.
Do kids get sensitive teeth?
Yes, often from a cavity or new adult teeth coming in. Call us if your child avoids cold foods or complains when brushing.
Will I know the cost before treatment, and when do I pay?
Yes. Before any treatment beyond your exam and cleaning, you get a written plan with a cost estimate. If you have insurance, we check your benefits first and file the claim for you. Your portion is due at the time of service. We accept cash, check, major credit cards, and financing through CareCredit or Cherry for larger treatment. See insurance and payment.
