Teeth Whitening
Lightening by several shades in one in-clinic session or at home with custom trays, without harming the tooth.
- Session length
- 60–75 minutes
- Sessions
- 1 session (in-clinic) or 2 weeks (home)
- Afterwards
- Avoid strongly coloured food and drink for 48 hours
Whitening lightens discolouration on and within the tooth with peroxide-based gels. How much lighter depends on the starting shade and the cause; tea, coffee and smoking stains usually respond well.
In-clinic or at home?
In-clinic whitening gives a result in one session. At home, custom trays are worn daily for two weeks — slower, but with less sensitivity. Both can be combined.
Good to know
Fillings, crowns and laminates do not whiten. If you have fillings on your front teeth, they may need replacing after whitening.
How does the treatment go?
- Check-up and cleaning
Any decay or tartar is treated first; the starting shade is recorded.
- Gum protection
The gums are covered with a protective barrier.
- Whitening gel
The gel is refreshed in 15-minute applications.
- Afterwards
Fluoride is applied for sensitivity; the new shade is recorded.
