What this symptom means
Tooth sensitivity is a short, sharp response to a trigger such as cold air or drinks. Occasional mild sensitivity is common, but persistent or worsening sensitivity should be evaluated to rule out decay, cracks, gum recession or a problem with an existing restoration.
Common possible causes
- Enamel wear from acidic foods, drinks or aggressive brushing
- Gum recession exposing tooth roots
- Dental decay
- A cracked tooth or leaking filling
- Recent dental work
- Grinding or clenching
Warning signs to take seriously
- Sensitivity that lingers well after the trigger is removed
- Pain when biting or chewing
- Visible discoloration or a rough edge
- Sensitivity localized to one tooth
When it may be urgent
Sensitivity is not usually an emergency. Seek prompt evaluation if there is severe pain, swelling, fever or bleeding.
Safe temporary comfort measures
- Use a soft-bristled toothbrush and gentle technique
- Consider a toothpaste formulated for sensitive teeth as directed on the label
- Limit very hot, very cold and highly acidic foods and drinks
- Avoid brushing immediately after acidic foods
What to avoid
- Whitening products on sensitive teeth without professional guidance
- Brushing too hard or using a stiff-bristled brush
- Ignoring sensitivity that worsens over days or weeks
How a dentist evaluates the problem
A dentist typically reviews your triggers, examines the teeth and gums, checks bite pressure and may use cold testing or imaging when clinically appropriate.
Possible treatment categories
Recommendations depend on the underlying cause and the results of an examination. Possible treatment categories may include:
- Desensitizing agents applied in the office
- Fluoride treatment when clinically appropriate
- Repairing a filling, crown or exposed area
- Treating decay, cracks or gum inflammation
- A night guard when grinding contributes to sensitivity
Factors that can affect cost
- Whether restorative work is needed
- Whether imaging is required
- Materials used for any repair
- Whether more than one tooth is involved
