At Home Teeth Whitening System – How Does It Work?
You have decided to try a teeth whitening system at home. It is not clear how all this works, so in this article we will explore what goes on with the very popular procedures to make sure it is correct for you.
Before you buy a kit you should know not everyone will get good results. That is one reason to see your dentist before you make a purchase. Sometimes people who have white spots, infected gums, or decaying teeth may not be good candidates. The same problem could impact those who have fillings that are not all the same color. Another conflict could arise if you have caps or crowns on the front teeth. For this reason, if you have any doubts about your situation, you need to check it out with a dentist before proceeding.
Some at home whitening systems involve the dentist to get started. The dentist will take an impression or mold of your mouth. Then he will create a tray to apply the whitening agent to your teeth.
Most at home systems contain a 10% to 20% concentration of carbamide peroxide as the bleaching agent. Some have included a sodium fluoride to help with sensitivity and strengthening the teeth.
A thin application is applied to the trays you had molded. These are normally worn for 2 hours a day or during the night. The average time the process goes on is about 2 weeks. But some people require a longer duration to get the results they want.
The carbamide peroxide is effective because stains from substances like tea or coffee have penetrated the porous enamel layer of the teeth. The carbamide peroxide is also absorbed, and as a bleaching agent, creates an oxidation reaction that breaks down the stains.
For a huge number of people these at home teeth whitening systems work well. But in some instances, where perhaps a person is having problems with a sensitivity to the whitening agents, a dentist can devise a more comfortable process.
