Teeth Whitening Facts

Teeth Whitening is safe when it is professionally controlled  in capable dental hands.
Teeth Whitening is effective when the process is properly dispensed, controlled and monitored.
Teeth Whitening is long lasting when the correct personalised process is provided.

Most of us start out with sparkling white teeth, thanks to the tooth’s natural porcelain-like enamel surface. Composed of microscopic crystalline rods, tooth enamel is designed to protect the teeth from the effects of chewing, gnashing, trauma and acid attacks. But over the years enamel is worn down, becoming more transparent and permitting the yellow colour of dentin, the tooth’s core material, to show through.
During routine use, the tooth’s dentin remains intact while millions of micro-cracks occur in the outer enamel. It is these cracks, as well as the spaces between the crystalline enamel rods, that gradually fill up with stains and debris. As a result, the teeth eventually develop a dull, lacklustre appearance.

Teeth Whitening Options

We have two main teeth whitening options. These both rely on varying concentrations of whitening chemicals and varying application times. Best results are often achieved with a combination protocol using both options and customising the process for each individual requirement.

1. In-office whitening

The major benefits of in-office whitening are significant colour change is achieved in a short period of time, and your dental professional is monitoring the process on the spot. The process involves the carefully controlled use of a relatively high-concentration of whitening gel, applied to the teeth by the dentist or trained hygienist after the gums have been protected with a paint-on rubber coating. Generally, the whitening gel remains on the teeth for 15 to 20 minutes. This is repeated up to four of five times in one session to achieve the optimal results. Those with particularly stubborn staining may be advised to return for one or more additional whitening sessions, or may be asked to continue with an at-home whitening system.

2. Professionally dispensed at-home whitening kits

At-home whitening kits incorporate an easy-to-use lower-concentration whitening gel that remains on the teeth for an hour or longer (most often overnight). This process is repeated for as long as it takes to achieve the desired results. The lower the whitening percentage, the longer it may safely remain on the teeth. The gel is applied to the teeth using personalised custom-made whitening trays that resemble thin mouth guards. These trays need to be very neatly fitting and are made from personal impressions of your teeth. Professionally dispensed at-home whitening kits provide good results. At-home kits are a cost effective method but do take longer, can be less comfortable, and maybe less effective than in–office procedures.


Sensitivity can be a problem with all whitening processes and is carefully monitored to reduce the effects.

Chemical buffers can be applied to reduce the problem during and after the procedures. Sometimes the in-office process may be foreshortened if the problem is severe. Your dental professional is the best person to monitor this.
