What is the safest effective way to whiten your teeth?

The most predictable whitening approach is chosen after checking enamel, dentine, gums, existing restorations, and the source of staining.

Why can whitening cause sensitivity or gum irritation?

Sensitivity and gum irritation depend on gel concentration, contact, duration, tray fit, and individual susceptibility. Whitening does not change most restorations.

What should you do before and during whitening?

Have an examination first, follow product directions, keep gel off gums, and stop if significant irritation develops. Ask whether trays or in-office treatment suit the stain.

When should whitening symptoms be checked by a dentist?

Seek care for severe sensitivity, chemical irritation, pain, uneven darkening, or a single dark tooth. Do not whiten over untreated decay.

What should you ask about your whitening treatment plan?

Ask what caused the colour, whether restorations will match, and what concentration, fit, and schedule are appropriate.

Frequently asked questions

Can whitening remove every stain?

No. Some internal stains and restoration colours need another approach.

Why are gums sore afterward?

Gel contacting gum tissue or a tray edge can irritate it.
