If you take care of your teeth and are aware of what caused the stain and discolouration in the first place and try to avoid them in the future then the answer is
Brush your teeth twice daily with a recommended tooth paste or tooth serum.
If not, the results will generally last for one to two years but with regular gentle top-up treatments you can maintain the original treatment's effect.
Our recommended protocol for maintaining the desired effect is:
Year One: overnight whitening top-up with a home custom fitted whitening tray and recommended whitening agent every two months
Year Two: overnight whitening top-up every four months
Year Three and beyond: overnight whitening top-up every six months.
At the Ryde Studio we have many patients that follow this protocol are very happy with the maintained results.
