Over a quarter of the UK adult population have had cosmetic treatments.1 The nation’s top teeth concern is yellow stained teeth. Worries about yellowing or stained teeth prey on the minds of four in ten adults, making cosmetic issues the most prevalent oral health concern.2
Philips Zoom! is chosen by millions – trusted by over 4 million patients worldwide already. The WhiteSpeed lamp in Philips Zoom! works to accelerate the whitening process.

The dual barrel system, unique to Philips Zoom!, means products do not require refrigeration
The optimal pH level for chemical reactions is around pH 7-9. Generally at this pH peroxide is unstable and therefore requires refrigeration. Philips Zoom! has developed a unique dual barrel system where the peroxide is held in a separate chamber at a stable pH of 4-5 without the need for refrigeration. This is then mixed with the ‘activator’ to raise the pH to 7-9 at point of use.

How ACP works
The shade of a patient’s teeth is the result of organic colour molecules within the otherwise whitish materials which make up the dentine and enamel. These molecules are coloured because they have sections called chromophores that absorb certain wavelengths of light, and reflect others.
The colour arises from a long chain of alternating carbon single and double bonds within the chromophore, which can absorb light energy. The length of this chain determines the colour that is absorbed – the longer the chain, the longer the wavelength which is absorbed, and the stronger the colour.
Applying hydrogen peroxide breaks double carbon bonds within the chromophore making the teeth appear whiter. This disruption of the double bonds in the chain disrupts the conjugation length, and it is now so short that the molecule appears colourless. The stains have in effect been “decolourised”.
Chromophores in tooth stains absorb blue light, which is why they appear to be yellow/red.
Since blue light is quite naturally absorbed by the yellow-red stains in the tooth, we make use of this energy in the whitening process. The electrons in the in chromophore are excited to a state of increased energy by the natural blue light absorbtion. “Excited” chromophores react with the hydrogen peroxide radicals far more rapidly and thoroughly than they would otherwise do, decolouring the molecule in much the same way, only much more effectively.
Note: these reaction steps effectively occur simultaneously
Using the WhiteSpeed lamp adds energy to the molecules, speeding up the reaction.
Sceptical?! - This photochemical principle is actually very similar to that used in standard blue light cured dental restoratives. In that case, added yellow pigments in the bonding resin absorb blue light in just the same way, but the light energy is now purposefully directed into reactions which cure the resin rather than into self-reaction with bleaching agent.
