If your teeth are not sensitive, you can do the whitening for six days consecutively until the fluid lasts. Usually sensitivity appears after the first day and if this occurs, you can leave out a few days and continue the whitening later.
You should do the whitening process until you have achieved the expected result, approximately after six uses. The whole treatment should not last more than two weeks. To keep up the good result you should avoid any red, yellow, or dark coloured food or drink or very cold or hot drink and food, while you are doing the whitening and up till two weeks after that.
Please do not drink: coffee, tea, red wine, coke. And avoid: any food that contains red or yellow food colouring i.e. tomato soup, curry, ketchup.
An at-home kit can be used to maintain the newly whitened teeth that were bleached with the chairside method. A hygiene treatment may be required before the at home kit can be applied.
