Teeth whitening can cause temporary sensitivity in some people. This usually feels like a short, sharp response to cold air or drinks and often settles after treatment stops.
Why sensitivity happens
Whitening gel passes through the outer tooth layer and can temporarily irritate the inner nerve. Stronger products, longer contact time and existing sensitivity can increase the chance.
Who may be more sensitive?
- People with worn enamel or exposed roots.
- Teeth with cracks or cavities.
- Gums that have receded.
- People who already react to cold drinks.
How can it be reduced?
The dentist may change the strength or timing of the whitening product, use a sensitivity gel, or recommend toothpaste for sensitive teeth. Cavities and gum problems should be treated first.
When should you stop?
Stop and contact the dentist if pain is strong, affects one tooth, continues for a long time or is joined by swelling. Whitening should not be used to hide a dental problem.
