  • Bleaching is the most effective method of whitening teeth.
  • the bleaching compound works by oxidising coloured unsaturated compounds into carboxylic acids and alcohols.
  • legal limits are imposed on their use.
  • many commercial bleaching products attempt to work up to the maximum limit and then accurate dosing becomes critical. Without accurate dosing any device would have to operate well clear of any legal limits and thus reduce their effectiveness.
  • Preferred bleaching compound are hydrogen peroxide, sodium percarbonate peroxide and carbamide peroxide.
  • the bleaching is enhanced by the presence of a catalyst.
  • the device For peroxide bleaching to be most effective it needs to left on the teeth for up to 30 minutes. This may be impractical for an applicator device. Therefore it is preferred that the device also delivers a catalyst which accelerates the whitening process.
  • One preferred catalyst is the iodide ion, which may be provided for example by potassium iodide.
  • the addition of the iodide to a peroxide in a basic medium yields free radical oxygen and water, generating large amounts of heat and depleting the hydrogen peroxide in a matter of minutes.
  • the free radical oxygen generated in this reaction can be utilised to oxidise the organic molecules responsible for staining which causes them to become colourless and soluble in water.
  • the iodide ion is therefore a convenient method of providing potent bleaching without the need for external energy supply such as light, lasers, heat sources etc.
  • Another possible combination is bleaching agent and peracid. This unstable combination gives excellent whitening when used in the device according to the present invention.
  • the fast catalytic reaction is part of the reason why so-called whitening toothpastes are less effective than separate applicator techniques.
  • the present invention permits the use of a catalyst to give much greater whitening effect but also with the convenience of a toothbrush applicator.
