How does Professional Teeth Whitening work?

How long does whitening teeth take ?
In the majority of patients, teeth appear whiter within a few days. Optimum results are usually achieved within 2 weeks.
How long do teeth whitening results last?
With good maintenance, results can last for years. On average, teeth will begin to fade back towards their original colour slowly after a few years. However, a simple top-up procedure can help to maintain the initial results. Usually, application of whitening gel for 1 or 2 days is sufficient. Whitening gel syringes are purchased from the clinic. Good homecare allows results to be maintained for longer. Avoid smoking and reduce the consumption of certain foods and drinks. Limit the intake of red wine, turmeric, coffee and tea. Regular dental hygiene professional cleanings will help avoid stain build up and maintain your white smile.
Teeth whitening for sensitive teeth: Is it safe?
Yes. Professional teeth whitening is a safe procedure when provided by our dentist. Patients who have sensitive teeth prior to teeth whitening are more likely to have sensitivity during the process. This can be managed by the use of certain toothpastes and other simple procedures we recommend before the whitening process. Philips Zoom NiteWhite also has the advantage of containing special ingredients. These help reduce sensitivity and protect the enamel. Your initial consultation and exam allow us to assess if you are a suitable candidate for teeth whitening.
