Tooth Sensitivity
Why teeth become sensitive and what you can do about it.
What is Tooth Sensitivity?
Tooth sensitivity, or dentin hypersensitivity, is a common condition causing sharp, temporary pain in teeth when exposed to certain triggers like hot, cold, sweet, or acidic foods and drinks.
Causes
Sensitivity occurs when the dentin (inner layer) becomes exposed:
- Worn tooth enamel from aggressive brushing
- Gum recession exposing tooth roots
- Cavities or cracked teeth
- Worn fillings or dental work
- Teeth grinding (bruxism)
- Acidic foods eroding enamel
- Recent dental procedures (temporary)
Treatment Options
Several treatments can help:
- Desensitizing toothpaste (Sensodyne, etc.)
- Fluoride gel or varnish at dental office
- Bonding to cover exposed roots
- Surgical gum graft for severe recession
- Root canal for severe, persistent sensitivity
Home Care Tips
Manage sensitivity at home:
- Use a soft-bristled toothbrush
- Brush gently in circular motions
- Use desensitizing toothpaste consistently
- Avoid acidic foods and drinks
- Wear a night guard if you grind teeth
- Wait 30 minutes after eating acidic foods to brush
Frequently Asked Questions
How long does it take for desensitizing toothpaste to work?
Desensitizing toothpaste typically takes 2-4 weeks of consistent use twice daily to show significant results. Some people notice improvement sooner, but full effectiveness usually requires regular use over time.
Is tooth sensitivity a sign of a cavity?
Sensitivity can be a symptom of a cavity, but not always. If sensitivity is limited to one tooth, persists, or is accompanied by pain, see your dentist to rule out decay or other issues.
Can sensitive teeth go away?
Yes, with proper care and treatment, tooth sensitivity often improves. Using desensitizing products, addressing underlying causes, and maintaining good oral hygiene can significantly reduce or eliminate sensitivity.
