We recommend using our Step by Step Colgate Optic White Whitening Guide.

  1. Thoroughly brush your teeth with fluoride toothpaste.
  2. Place a small drop of Colgate Optic White Gel in the tray, for each tooth that needs to be whitened (small pen drop).
  3. Place the mouth tray with gel into mouth and over teeth. Press gently against the mouth tray with your fingers to put tray in place.

My dentist did not provide a full amount of whitening gel to get through 30 days treatment. The cost of an extra gel from my dentist was high. I looked online and found THE HOUSE OF MOUTH. I ordered three extra gel syringes for the price of one from the dental surgery. Identical products 1/3 of the cost - WOW... THE HOUSE OF MOUTH has a great website and 5 STAR service. Thanks to all at THE HOUSE OF MOUTH.

I don't normally write reviews, but am making an exception for House of Mouth. The reason is that they provide a top notch service at a cost far less than you'd pay at the dentist. It costs a bundle to get a dentist to make those bleaching trays to whiten your pearlies. House of Mouth will do a perfect job for way less. And you don't have to go into an appointment - you can do it all by mail. Dan is lovely to deal with. And the whole process is easy.
