Teeth Whitening

Teeth Whitening Johor Bahru Before After

Teeth whitening or bleaching is a cost effective and minimally invasive way to improve your smile. White smile is often desirable. When teeth become yellowish over time, our dentist can lighten the shade of natural teeth without drilling or adding to the tooth structure.


Hydrogen Peroxide (H2O2) is the most commonly used active ingredient in whitening product. It is often delivered as either hydrogen peroxide or its predecessor carbamide peroxide. When in contact with water, carbamide peroxide converts into hydrogen peroxide at a ratio of 3:1. For example, whitening product containing 30% carbamide peroxide has about 10% of hydrogen peroxide.


As a powerful oxidising agent, hydrogen peroxide diffuses into the tooth, breaking down to produce free radical oxygen. These unstable free radical then attach to the organic pigment molecules to form smaller and less pigmented molecules which reflect less light to give whitening effect.
