Our teeth can discolour through the years as our enamel wears down. The wear of enamel allows dentine, a yellow coloured substructure that makes the core of our teeth to show through.
This is what gives our teeth a yellowish tint.
Teeth whitening, also known as teeth bleaching, helps restore teeth to a shiny white colour through the use of safe bleaching agents.
How it is done
There are 2 popular teeth whitening options available in our practice.
The first, in-office teeth whitening, produces a significant colour change in your teeth in a short amount of time, usually within an hour. The procedure is done at our dental clinic by applying a high concentration bleaching gel on the teeth after they are protected with a special shield.
The bleaching agent is activated with a special ‘laser’ light.
The second method involves the use of home whitening kits with custom made trays. These are purchased from our clinic for use at home. The concentration of the gel used in these kits is usually lower than that used for in-office whitening, and thus the gel has to be applied for,longer periods of time.
Typically, the trays are worn a few hours a day or overnight for a few days or weeks depending on patient and product.
It is best to consult Dr Ang regarding the best whitening option for you.
