What is tooth whitening?
It is a bleaching process that lightens discolorations of enamel and dentine. It uses a mild solution retained in custom-fitted trays that is worn over your teeth. Tooth Whitening is one of the easiest cosmetic treatments and can give fantastic results in a short period of time, as most teeth lighten within a few weeks.
What causes tooth discoloration?
There are many causes to include aging, consumption of staining substances (coffee, teat, colas, tobacco), trauma, nerve degeneration, and old restorations. During tooth formation, consumption of tetracycline or excessive fluoride may also cause discoloration.
Who may benefit form tooth whitening?
The vast majority of people will benefit from tooth whitening. However, there are some cases when treatment may not be effective. A dentist may determine viable candidates for the process through a thorough oral examination and diagnosis. Darker stains such as those caused by antibiotics may take longer to respond to treatment. The degree of whiteness will vary from patient to patient, depending on the structure of the teeth, the number of applications, and/or the duration of time that the system is used.
Is the process safe?
Yes! Research and clinical studies indicate that teeth whitening with carbamide peroxide or hydrogen peroxide under the supervision of a dentist is safe for teeth and gums. Infact many dentists consider this whitening process to be the safest cosmetic dental procedure available today.
How does it work?
The whitening gel is placed in a thin bleaching tray that fits over your teeth. As the active ingredient in the gel is broken down, oxygen enters the enamel and dentine and bleaches the coloured substances. The structure of the tooth is not changed; only the tooth colour is made lighter.
How long does it take?
Results are usually seen after the first application. Maximum results generally occur when the process is continued over 10-14 days.
Are there any side effects?
Some people experience temporary increased tooth sensitivity to cold during the treatment. These symptoms disappear within 1-3 days after interruption or completion of the treatment.
How long do the results last?
The teeth will always be lighter than they once were; however, some patients may need a tooth whitening ‘touch-up’ for 1-2 days, once or twice a year. In order to maintain the whitest tooth shade possible, it is best to avoid substances like coffee, tea, red wine and tobacco.
Tooth Whitening at Alexandra Park
At Alexandra Park we offer two types of whitening systems.:
The ‘home whitening’ system is where you are given custom made trays to take home with you. The trays are used in conjunction with a special gel and are worn for two hours daily. If life is hectic and you don’t manage to do this everyday then it doesn’t matter, they can be whitened when it fits in with your schedule but just takes a little longer.
The system we use is Nite White ACP. It is a state of the art whitening system that not only whitens teeth in matter of days but it also restores enamel luster. It is the only take-home whitening brand with patented ACP(Amorphous Calcium Phosphate) technology which fills tooth surface defects to restore the enamel surface.
At Alexandra Park, we use Zoom 2! Whitening Technology. It takes approximately 45 minutes and your teeth will become dramatically whiter. After your whitening treatment, your teeth should continue to be lighter than they were before the treatment.
During the procedure, your teeth will be exposed to Zoom! gel as well as the Zoom! Light. This light helps the gel penetrate into your tooth and as such improve your results. A study has shown that the average improvement is by up to 8 shades lighter! The only way to achieve these dramatic results is under the close supervision of our dentists.
During bleaching your tissues in the mouth will have to be completely protected from the light, so a short preparation for this is required. After your Zoom! Session, a short 3 day course of home whitening in custom made trays is recommended to help preserve your new white smile.
Protective eye wear is required and will be provided for the Zoom 2! treatment.
