Most of our Clients teeth Whiten 2-8 shades
Some very stained teeth can whiten 12-14 shades
Be Careful of Results Claims
Results claims can be exaggerated by Unregistered Practitioners by using a 30 or 36 shade chart rather than the Global standard
16-shade VITA guide as used by Dentists and Professional Teeth Whitening Aestheticians
A claim of 10-shades may in fact be only 3-shades whiter!
We use the professional Global Standard 15-shade VITA guide, we measure your teeth shade before we start, then again after your teeth whitening.
This means you can see exactly how many shades whiter your teeth have become, rather than some exaggerated embellished claim

However, there is a difference in the New Generation Whitening Gels we use…Safety.
Our modern new generation whitening gels are 580% LESS CAUSTIC than what many NZ Dentists & Hygienists still use and therefore we can offer you considerably less risk of nasty side-effects such as sensitivity; however, to be fair, many Dentists & Hygienists globally are now switching to Catalytically Activated Low Peroxide New Generation Whitening Gels.
Professional whitening involves applying a peroxide-based gel to the teeth, which breaks down chemical bonds in stains. In-chair treatments often use an LED light to activate the gel for faster results.
