Generally speaking, there are two types of teeth whitening kits – “take home” and “in-chair”. As the names suggest, it all depends where the whitening takes place. Take-home whitening kits include upper and lower custom-made whitening trays and 4 tubes of whitening gel that lasts up 12-24 months in your fridge. This method allows you to top up the whiteness and brightness of your smile at your own pace. When you’re all out of whitening gel, you can buy more whitening gel from us at a reduced price as you’ll already have your custom whitening trays. The other method is in-chair bleaching, and this is done in the dental chair at our clinic as a one-off appointment. In this method, a higher percentage of gel is utilised to achieve results in a shorter amount of time. Sometimes, this method can cause increased sensitivity. When your appointment is done, please note this is as light as your teeth will go. As such, your dentist may recommend the take-home whitening kit for you to achieve ongoing optimum results. Due to the extra time you spend with us in the clinic, the cost of in-chair whitening is more than a take-home kit.
