Chairside whitening is done in-clinic by a dental professional and the single session usually takes 60 to 90 minutes to complete.
Chairside whitening systems, such as Zoom, use blue wavelength light to activate the hydrogen peroxide gel to form free oxygen radicals. These oxygen radicals enter the top layer of your tooth structure, known as enamel, to bleach any discoloured substances.
The whitening gel contains only 25% hydrogen peroxide and is buffered at a near-neutral pH value that is compatible with your tooth enamel.
A whitening lamp shines a gentle, blue light on your teeth to activate the process. The procedure emits virtually no heat and no harmful UV (ultraviolet) light.
- A short preparation to cover your lips and gums, leaving only your teeth exposed
- Gel is applied and activated by the light source
- During this time, you can relax, watch movies or listen to music
- At the end of the whitening session, you can go home with a brighter, whiter smile
Teeth Whitening Maintenance
The colour achieved is not permanent and slowly fades over 8 months to a year. The speed and intensity of the fade vary according to individual and depends on your dietary, social, and teeth cleaning habits.
To upkeep your new sparkling whites:
- Have regular visits to the dentist every 6 months to a year
- Practise proper and effective tooth brushing methods and oral hygiene habits
- Maintain the results obtained with a maintenance home whitening kit
Do’s & Don’ts
What You Should Do Before Treatment
- Do Practice Good Oral Hygiene Before Whitening: If you have food build-up on your teeth, it would prevent the whitening gel from reaching those areas. As such, you might not obtain desirable results. To achieve optimum results, schedule your dental check-up and cleaning right before you intend on going through whitening.
What You Should Do After Treatment
- Avoid Food That Can Stain Your Teeth: The first few days after treatment are most crucial. Refrain from smoking and avoid consumption of dark liquids / foods. Brush and floss as normal using the desensitising toothpaste provided. An important point to note — the less you indulge in food that stain your teeth, the longer your results will last.
- Don’t Consume Acidic Food: Avoid consumption of acidic (sour) substances up to 48 hours post whitening to reduce risk of sensitivity. Do use the desensitiser gel and toothpaste provided.
