The Science of a Teeth Whitening Kit

If you have ever thought about whitening your teeth, today we will examine the science of how a tooth whitening kit works.  We will look in detail at how a teeth whitening kit interacts with your teeth to remove stains and keep them looking bright and white. 

What is the makeup of a human tooth?

Our teeth are made up of four different types of tissue.

  1. PULP This is the centre part of a tooth, it is made up of connective tissue, blood vessels and cells.
  2. DENTIN contains microscopic tubes.  When dentin loses its protective covering (Enamel) the tubes allow heat and cold and sticky foods to stimulate the cells causing sensitivity.
  3. ENAMEL is a hard coating protecting the tooth from temperatures and chemicals.
  4. CEMENTUM is a hard connective tissue covering the tooth root.

What is a teeth whitening kit?

       The teeth whitening kit as an inexpensive option that can be used at home to whiten your teeth instead of taking a trip to the dentist.  The kit usually contains a powerful dental grade teeth whitening solution which uses a whitening gel applied to the teeth, which is then activated by a LED light.  The kit offers multipole uses. Each session usually is around forty minutes.

The Science of a Teeth Whitening Kit

Teeth whitening kits contain phthalimidoperoxycaproic acid (PAP) to bleach the teeth, potassium nitrate to desensitise the nerves, and sodium chlorite for stain removal. These ingredients can lighten stains on the surface of the tooth. These kits use the same blue light technology as your dentist. The led light activates the whitening formula and breaks down and removes stains after each session.  Usually, you can see obvious results after one your first session.
