Teeth whitening uses products or procedures to lighten the colour of natural teeth. Results depend on the cause of discolouration, the method and existing restorations. Capilano Mall Dental lists teeth whitening among its Edmonton services.
Why tooth colour changes
Tooth colour can change with age and may be affected by foods, drinks, tobacco or other causes. Whitening does not address every type of discolouration. The Canadian Dental Association advises discussing the cause with a dentist, especially when a tooth has a crown, filling or root canal history.
Whitening options and limitations
Whitening products and methods differ in strength and application. A dentist can explain which options are available and what results may be realistic for the teeth involved. Whitening changes natural tooth colour but does not lighten crowns or fillings in the same way. Tooth sensitivity or gum irritation can occur with some methods.
Questions before whitening
Ask which method is being considered, what instructions to follow and what to do if sensitivity develops. Discuss existing restorations and any untreated dental concerns before starting. Request a written estimate that identifies assessment, materials and follow-up. Avoid guaranteed shade or duration claims; results and maintenance vary.
Common questions about teeth whitening
Is teeth whitening suitable for everyone?
No. Suitability depends on oral health and the cause of the colour change. A dentist can assess the teeth and discuss options.
Will whitening change crowns or fillings?
Whitening affects natural tooth colour but does not lighten crowns and fillings in the same way. Ask how existing restorations may affect your plan.
Can whitening cause sensitivity?
Sensitivity or gum irritation can occur with some whitening methods. Ask the dentist which method is being considered and how to respond to side effects.
