Home Teeth Whitening Kit

Instructions for use.

This procedure involves the use customised bleaching trays corresponding to the outside surfaces of your teeth, filled with small amounts of Hydrogen Peroxide whitening gel.

  • Clean your teeth thoroughly before each use, including use of floss or specialist brushes. Rinse any toothpaste away.
  • Fill the supplied bleaching trays with a small amount of the whitening gel sufficient to cover the dimples/reservoirs on the inside of each tray.  Care must be taken not to overfill the tray, as this could be forced out over your gums when inserted.
  • Excess material should be removed from the gums with a tissue, cotton wool or a dry toothbrush after insertion of the trays.
  • The filled trays are worn for 30 mins -8 hours (overnight) each day as directed. You should not eat, drink or smoke whilst wearing the trays. If they are removed during this process, then the tray will need to be refilled with new gel. The whitening process works at different rates for each individual, but most patients report that a noticeable effect after just 1-2 weeks. Sufficient gel is given for the initial process to work with some remainder for topping up after six months or a year.
  • Rinse your mouth with lots of lukewarm water to remove any remaining gel when the trays are removed. Wash the tray with cold water and dry thoroughly with tissues before storage.
  • Do not drink or eat for 30 minutes after removing trays.
  • Sensitivity is a normal feature of the whitening process. It usually lasts only for a few days after the duration of the whitening period. Due to this sensitivity, you may choose to wear the trays every other day or less to achieve a gradual change in appearance.
  • It is possible to over-lighten the teeth. Stop using the trays and gel when you are happy with the colour. Remember that the natural colour of teeth is never pure white. The whitening gel will lighten your teeth, but not necessarily remove internal stains; in these circumstances the teeth may never achieve a harmonious colour. The gel will not lighten crowns, veneers or fillings. If you have any of these restorations then the teeth should be lightened prior to their replacement.
  • It is not necessary to lighten the back or molar teeth, the tray may not even cover these areas.



  • Sensitivity is a normal feature of the whitening process. It usually lasts for a few days after the duration of the whitening period. Due to sensitivity, you may choose to wear the trays every other day or less.
  • If sensitivity is intense, then the trays can be filled with sensitive toothpaste, such as ‘Duraphat’ or ‘Sensodyne’ toothpaste and worn for a few hours.
  • If the gel comes into contact with skin, wash with soap and water. If you swallow a significant amount of gel drink large amounts of water or milk.
  • Refrigerate the gel for storage and keep out of reach of children.
  • In rare cases, an allergic reaction to the gel may occur. You will have widespread swelling of the mouth and some discomfort. Discontinue use and contact your dentist.
  • Avoid or limit food that can stain your teeth such as: chocolate, carrots and oranges.
  • Avoid or limit drink that can stain your teeth such as: tea, coffee, strong fruit squashes and red wine.
