Are you afraid to enjoy your favorite ice cream because your teeth hurt? Does the first sip of hot coffee send a shooting pain through your teeth? You’re not alone — research suggests about one in every eight Americans suffers from tooth sensitivity. The good news is that it’s treatable. Here’s what causes sensitive teeth and how to get rid of the problem.
What Causes Tooth Sensitivity?
Teeth become sensitive when their outer protective layer — the enamel — is damaged. Healthy enamel is a highly mineralized shell that protects the softer layers underneath: the dentine and the pulp. When oral hygiene is neglected, bacteria in plaque and tartar release acids that gradually wear the enamel away, exposing the dentine and pulp, which contain nerves and blood vessels. Once those layers are exposed, anything hot or cold triggers sudden, sharp pain — a condition called dentinal hypersensitivity.
Besides poor oral hygiene, the American Dental Association lists these common causes:
- Dental cavities
- Worn dental fillings
- Dental trauma that damages the enamel
- Gum disease
- Congenitally weak enamel
What Happens If I Don’t Treat Sensitive Teeth?
Tooth sensitivity is often the first stage of a chain of dental complications. Exposed dentine is prone to developing cavities; over time, infection can reach the interior of the tooth and require root canal treatment. If the infection progresses far enough, the tooth may need to be extracted. Sensitivity should never be taken lightly — the earlier it’s treated, the simpler the fix.
How Is Tooth Sensitivity Treated?
- Oral hygiene maintenance — regular flossing, brushing, and dental checkups are the first step. They won’t restore lost tooth structure, but they prevent further damage. Limiting acidic foods helps too.
- Desensitizing toothpaste — these contain compounds like calcium, phosphate, fluoride, and arginine that replenish lost minerals and plug the exposed dentinal tubules. Very effective for early-stage sensitivity.
- Fluoride gels and varnishes — professionally applied fluoride reinforces weakened teeth, typically once or twice a year. Prescription fluoride supplements for home use may also be recommended.
- Dental restoration — when sensitivity comes from a damaged tooth with exposed dentine, restoring the structure is the answer: bonding or inlays for small defects, or an onlay or biomimetic restoration for larger ones.
- Gum grafting — when receding gums expose the tooth roots (which are less mineralized than enamel and far more sensitive), a gum graft restores the gum height and covers the exposed root.
- Root canal treatment — the last resort for a grossly damaged tooth with irreversibly inflamed pulp. The inflamed tissue is removed, the canals are disinfected and sealed, and the tooth is restored with a permanent filling and, if needed, a crown.
Tooth sensitivity affects nearly everyone at some point, but it’s easy to prevent with good oral hygiene and regular checkups.
