What's Involved in Teeth Whitening?
First, your dentist will determine whether you are a good candidate for teeth whitening, and also what bleaching system would provide the results you want.
At your initial appointment, we'll make impressions of your teeth to fabricate a mouthguard appliance for you.
Your mouthguard is custom-made for your mouth. It is lightweight and can be worn while you are awake or sleeping, and thin you should be able to talk and work while wearing it.
At the next appointment, you will be given your mouthguard and the necessary dental teeth-bleaching materials. Your dentist will provide you with instructions on how to apply the gel and how long you need to use it each day.
Most bleaching systems require 10-14 days to achieve the desired whiteness.
How Does Teeth Whitening Work?
The active ingredient in the majority of our whitening agents is carbamide peroxide (CH4N202). When water comes into contact with this white crystal, the hydrogen peroxide lightens the teeth.
Is Teeth Bleaching Safe? Are There Side Effects?
Bleaching should be safe and effective. Some patients may experience minor gum irritation or tooth sensitivity which should resolve itself when the treatment ends.
What Can I Expect From Teeth Whitening?
Dental teeth bleaching can only provide a change in the colour of natural teeth; from grey to a lighter shade of gray, for example.
Bleaching won't change the colour of materials such as resins, silicates or porcelains.
If you are having major restorative work done (such as implants, crowns, veneers, and bridges), we recommend you do a course of bleaching prior to having the work done.
If the restorative work is matched to the yellow or grey teeth, there is no way to change the colour.
How long does it last?
Results typically last from one to five years, and the longevity of your whiteness depends partly on your personal habits, such as the frequency with which you drink coffee and tea.
With our cosmetic teeth bleaching kits, most patients will have at least one vial of bleaching gel left over from their initial course of bleaching. These leftover vials can be used in future to "touch up" your smile.
If you drink a lot of coffee, tea, or wine, you may have to do touch-ups every six months.
You can continue to use your custom mouthguard and buy vials of bleaching gel separately as you need them.
Re-treatment should take much less time than the original treatment, often only taking 2-3 applications to restore the desired level of whiteness.
Is teeth bleaching for you?
If your teeth are darkened from age, coffee/tea drinking, or smoking, teeth whitening may be a good choice for you.
Generally, yellow, brown, or orange discolourations respond better to bleaching than 'grey' stains caused by fluorosis, smoking or tetracycline.
If you have highly sensitive teeth, periodontal disease, or teeth with thin enamel, we may discourage bleaching and recommend porcelain veneers.
