Teeth Whitening Before and After PhotoAs it’s name suggests Tooth Whitening is a process of restoring a clean white colour to teeth. This process is required for teeth that have stained and yellowed over time.

What Is Tooth Whitening and How Does it Work?

There are a number of methods currently available, some as simple as using a particular toothpaste, through to bleaching procedures. Some methods can be done at home while some must be done professionally. Different methods fall under two general categories:

1. Bleaching

Methods involving bleaching endeavour to remove the colour of the stains on the teeth and allow the natural white to be seen again. There are a number of treatments available, some are done in the dentist chair, others can be done at home using several applications over a period of time.

2. Physical Removal

This method uses abrasion to physically and sometimes chemically take away surface stains. This is generally what a dentist does when you have a clean and polish.


Is Tooth Whitening Safe?

Yes. When whitening was in it’s infancy, high strengths of bleaches would sometimes cause the teeth to become very sensitive, but not permanently.

Today, after over a decade of research and clinical testing, bleaching methods have been refined and now lower concentrations allow the temporary sensitivity to be reduced. There is no more danger in tooth whitening than in drinking a cup of coffee.

Is Tooth Whitening Permanent?

Not necessarily. Staining of the teeth occurs over time and is a result primarily of drinks such as coffee, red wine, soft drinks, high sugar content foods, lollies and chocolates. If after a whitening treatment you are able to avoid all stain causing food and drink then you may not need whitening again. With proper care and dental hygiene the whitening will last longer.
