There are a variety of teeth whitening methods, each which varies in efficacy and speed of results. One such version utilizes a tray filled with special whitening gel. This gel then bleaches your teeth gradually, every time you wear the trays. Sometimes they will want to monitor this in the beginning to see if any changes need to be made to your tray, but most of the time, after the initial procedure, you will be able to do the rest yourself.
For example, sometimes the dentist will give you a custom-fit tray filled with the special gel so you can insert it yourself. You may wear it throughout the day, depending on whether you can do this or not, or else you may have to put it in at night so the whitening can work throughout the day.
In some other procedures, this may involve strips instead. Sometimes a dentist will also recommend that you use special toothpaste. The main approach involves taking off stains.
