Zoom Teeth Whitening is a clinic-based LED light-assisted chemical bleaching performed by our dental team to lighten the natural colour of your teeth.
This process only works on natural teeth and will not lighten existing fillings, veneers or crowns.
Tooth discolouration may be caused by external stains from smoking and the consumption of coffee, tea, red wine, soy sauce or dark-coloured fruit juices. Ageing also causes your teeth to slowly yellow over time as the enamel layer wears down.
Other sources of tooth discolouration are internal, such as tetracycline antibiotic staining, dental decay, enamel defects, leaking amalgam fillings or necrotic pulp stains (in a dead/root canal-treated tooth). These may not respond that well to Zoom and other treatment options may be more suitable in order to achieve the desired result.
Step 1: Consultation
A thorough examination is required to assess if you are suitable for the Zoom whitening treatment. The bleaching gel should not be applied on decayed teeth/open cavities, around inflamed gums, or on extremely worn teeth. So these conditions should be treated first, before the whitening can be done safely.
We will advise you on how much your teeth will lighten with Zoom and maintenance instructions will also be given to help you keep your smile as bright for as long as possible.
It is also common for our patients to have custom teeth whitening trays made so that it is easy to maintain the whiteness of teeth at home, with a lower concentration gel.
Your starting teeth shade will then be chosen together with you.
Step 2: Preparing your Teeth
Your teeth will be carefully cleaned to remove plaque and debris. A protective gel barrier is applied to the gum margins and the rest of the soft tissues are covered to prevent irritation from the Zoom lamp and the bleaching gel.
This allows us to use the maximum strength of hydrogen peroxide bleaching gel (25%), which is only available to licensed dental professionals.
In some cases, you may also be given an oral painkiller to reduce sensitivity during the procedure.
Step 3: Zoom Whitening Procedure
After applying the bleaching gel onto your teeth, a strong LED light is used to accelerate the chemical bleaching process. As the bleaching gel is exposed to the light, it breaks down stain molecules within the tooth structure into colourless compounds. The depleted gel is removed and fresh gel is reapplied at the start of each 15 min cycle. 2-4 consecutive cycles of 15 minutes are normally required.
Step 4: Whitening Complete!
The bleaching gel and barrier material will be removed at the end of the procedure.
Some patients experience increased tooth sensitivity after Zoom. A desensitizing gel and desensitizing toothpaste is recommended for the first 1-2 days after Zoom, and we will instruct you on how best to apply these to your sensitive teeth.
IMPORTANT: Avoid exposing your teeth to coloured cosmetics (lipstick/lip balm), coloured food and beverages for the first 48 hours.
Your dentist may review your bleaching after 1-2 weeks to assess the final shade. It is normal to experience some fading after Zoom as your teeth rehydrate.
Some patients also have bleaching trays made for 3 monthly top ups using home bleaching gel.
In recent years, provision of aesthetic dental treatment (teeth whitening, veneers, braces) by non-dental professionals has increased. Therapists and beauticians operating out of salons, spas, beauty parlors and some even from their own homes, offer such treatment. These providers offer what seems to be the same treatments as those performed by licensed dentists at a much lower fee, promising similar results.
The short answer is, whitening or other dental procedures not carried out by licensed dental professionals is done at your own risk. There is no guarantee of predictable success and there is increased risk of material harm (from unlicensed bleaching chemicals being used in your mouth and soft tissue burns). You will have no recourse should the procedure go awry.
