Tooth Whitening Frequently Asked Questions

How does tooth whitening work?

The active ingredient (either carbamide or hydrogen peroxide) is broken down, allowing oxygen to enter the enamel and dentin, causing the stains to be lightened. The strength of the active ingredient helps to determine the maximum lightening shade possible.

How white will my teeth get?

This will depend on your teeth - everyone's teeth are different. If your teeth are heavily stained from coffee or smoking, you will probably see a big change. If your teeth are not heavily stained, the change will not be as great.

Do all teeth whiten evenly?

With all products there is an overall whitening of all teeth. The biting edges of the teeth are more likely to whiten faster than the areas adjacent to the gum. BriteSmile will produce the most uniformed result, followed by dentist administered power whitening. It should also be noted that in some patients, whitening can result in a frosty, chalky appearance of the teeth, this is due to areas of concentrated fluoride and will revert to it's previous more natural appearance after several weeks.

Are my teeth more easily stained now that they have been whitened?

No, the chance of staining your teeth are not increased once they have been whitened.

What causes teeth to stain again after bleaching?

The same things that made them stain in the first place, i.e. general ageing, red wine, smoking, tea, coffee, coloured foods etc.

Will my crowns, veneers and fillings get whiter?

No, only your natural teeth will.

Are there any side effects to tooth whitening?

For the majority of patients there are none. However, some will experience temporary sensitivity (dull or sharp) on the teeth and / or the gums. This sensitivity will subside after several hours of stopping the treatment. Abstain from carbonated drinks, citrus foods and beverages to avoid sensitivity a few hours after the treatment.
