What Is Laser Teeth Whitening?
Laser (or light-activated) whitening is an in-clinic procedure. A professional whitening gel is applied to the teeth and a laser or light is used with it. The gel does the whitening; the light is intended to support the process. It lightens staining from coffee, tea, smoking and ageing in natural tooth enamel.
What Happens During the Treatment?
- Your teeth and gums are checked first, because decay, gum problems or exposed roots need attention before whitening
- Gums and lips are protected with a barrier
- The whitening gel is applied and activated, usually in several short cycles
A session usually takes around an hour.
What One Session Can and Cannot Do
- A change in shade is often visible after one session, but how much depends on your teeth and the type of staining
- Some staining, such as grey or tetracycline-type discolouration, responds less well
- Whitening does not change the colour of fillings, crowns or veneers, so these may need replacing afterwards to match
- Results are not guaranteed to reach a specific shade
Sensitivity
Temporary sensitivity during or after whitening is common. It usually settles within a day or two. Tell the dentist if you already have sensitive teeth.
How Long Do Results Last?
Results fade gradually. How long they last depends on diet, smoking and oral care; regular cleaning and limiting staining food and drink help. See teeth whitening: benefits and considerations for the wider options, including home whitening.
Is It Right for You?
Whitening is generally considered for adults with healthy teeth and gums. Whether it suits you, and which whitening method is appropriate, is decided by the dentist who examines you.
