The color of your teeth may vary from white to yellow and even brown. In time, your teeth become stained and naturally darker. This is because they age and, also, because of other factors such as smoking, food or drink habits, and drugs like tetracycline and iron supplements.
One of the most popular methods these days is the home teeth whitening kit. This implies wearing a mouth tray or guard with hydrogen peroxide gel inside. This will reduce the dischromy, offering a whiter, brighter smile.
After making sure there’s no tartar build-up and plaque on your teeth, your dentist takes an impression of your dentition. This will help the fabrication of a mouth guard or tray. During the second visit, your dentist will show how to apply gel on the mouth guard and how to position it on your teeth. The time you’ll need to wear it is function of your teeth’s dischromy and gel concentration: the process can be as short as a few minutes or it can expand to as long as a few hours. A regular treatment consists of a two-day application, for one or two hours, for two weeks.
The whitening effect
The effects of home teeth whitening can last a few months or a few years. The degree of whitening you can get also varies from one person to another, depending on your teeth, their condition, and the bleaching gel used. However, preserving the effect depends on your eating, drinking and smoking habits. There is no such thing as a permanent color change of your teeth. You have to understand that the effect of whitening your teeth, however spectacular, cannot last forever and cannot prevent future staining.
What are the risks?
Because of the reduced concentration of hydrogen peroxide in the gel, there are minor risks related to home teeth whitening. The most common effect is related to teeth sensitivity.
