Professional teeth whitening steps
Checking the shade
The dentist will first record the shade of your teeth. That is to get an idea about the degree to which your teeth have to be whitened. It will also help the dentist to figure out how concentrated the whitening solution has to be to get that shade.
Cleaning and polishing
The dentist will clean and polish your teeth.
Cleaning your teeth also helps to remove of any existing plaque from your teeth, before whitening. The dentist will then use retractors to keep your gums, tongue, and lips from interfering with the whitening agent.
Coating with the whitening agent
Hydrogen peroxide solution, which is the best bleaching agent known for teeth whitening will be used to coat your teeth. The frontal side of your teeth will be coated, while the posterior side will be left out. This is because the purpose of whitening your teeth is just to improve the aesthetics of your smile, and the backside of your teeth doesn’t show no matter how wide you smile!
The solution temporarily opens up the pores in your teeth, penetrating them and fighting off the stains from within to whiten your teeth. The coating would stay on your teeth for nearly half an hour before the dentist decides to proceed to the next step.
Rinsing
Your mouth will then be rinsed, thoroughly.
