The Treatment

What does LED teeth whitening involve?

A solution is applied to teeth, before a plastic mouthpiece is inserted. An intense light will then be directed at teeth, designed to reduce yellow staining and return teeth to their earlier, natural colour.

How long will the session last?

A 60-minute appointment includes a consultation, whitening procedure, desensitisation and aftercare advice.

Does the treatment lighten crowns?

No, only natural teeth will be affected. Crowns, fillings and other dental work will remain the same colour, although some surface stains may be removed.

What does the aftercare involve?

Clients should not eat or drink dark, staining substances for 24 hours after the session. These include coffee, tea, red wine and coke; smoking should also be avoided.

G: What is your background in dentistry? What made you want to work in the industry?

"Coming from a family of three generations of dentists, dentistry runs in my blood.

The satisfaction of being able to restore a smile on someone's face every single day makes me want to work in this industry."

G: What do you enjoy most about your work?

This challenge to harmonise developing aesthetic sensibility and acquiring scientific knowledge makes my job enjoyable and satisfying."

G: What are some simple ways in which people can improve the health of their teeth, day to day?
