The process involves taking impressions of your teeth, from which we make special gum shields called trays which have a reservoir for the bleaching gel.
The trays are filled with a special gel and then placed over the teeth. This is worn at night, or can be worn for shorter periods during the day if night wear is uncomfortable or you are unable to tolerate it.
If you have any tooth coloured fillings in the teeth to be bleached these will not change colour, and therefore it may be necessary to replace these to match the new colour of the teeth once the bleaching is complete.
You will probably need to 'top up' the bleaching every six months for a couple of applications, you use the same trays and the cost of the gel is relatively inexpensive, the initial expense in related to the making of the trays.
There are other ways of whitening teeth, but this is the most reliable and flexible way and allows you to choose when they are light enough and when you need to repeat the procedure. It is also illegal for anyone who is not a dental professional to do tooth whitening. There are reasons why your teeth might not be suitable for tooth whitening or there may be underlying disease so it makes sense that this should be assessed before you embark on tooth whitening.
