There are two options for teeth whitening. You can decide to go for these services from a professional dentist and have it done in a short duration of time. The other option is to do it yourself by use of products at home. The latter takes time for results to appear. When these two options are compared, the professional one tends to receive more traffic these days than the DIY. That’s because the results are guaranteed within hours. Even if it is expensive, people still go for it. It is important to understand how the procedure is done to be prepared for whatever is coming.
Not everyone is a candidate to go for professional whitening services. That’s because the people with sensitivity and other serious teeth defects need to be isolated. Whitening the teeth where there are cavities may cause issues or complications. The dentist must go through all the teeth to ensure that one is fit for the procedure.
The reason why the teeth are being whitened is the fact that the natural surface of the teeth has already been covered by tough substances or coating. Instead of covering the coatings like for the case of dental crowns, they are manually eliminated by polishing. Rough, grainy and pumice materials are used to scrape away any plaque that tends to be permanent. This opens up the surface for more whitening as appropriate.
Use of gauze and retractors
After scraping, the chemical treatment comes next. Since these are chemicals and are not supposed to be swallowed, the dentists will go for certain equipment to keep away the oral structures from contact with the chemicals. Gauze will be used to ensure that the teeth are dry throughout the procedure. The chemicals used need not be diluted by the oral saliva. Retractors can also be used to keep away other oral structures away from the chemicals. The tongue, the cheeks, and the lips all need to be kept off the chemical region.
Gum line protection
All that needs whitening is the enamel which is the white surface. The gums right beneath them don’t have a thing to do with the whitening. Furthermore, they are living structures and any exposure to the chemicals will mean harm. Barriers are hence used to protect the gums from any contact with the chemicals.
After preparation, the teeth are then covered with carbamide peroxide or hydrogen peroxide which acts as the bleaching agents. Lasers or curing light may be used to activate the chemical peroxide. The chemicals will then be left on the teeth surface for a duration ranging between 30 and 60 minutes. Cleaning up then follows by rinsing. Fluoride may be used to curb sensitivity.
Dentists recommend that you don’t use certain products like coffee and other colored foods to prevent the same problem from coming back.
