Choose Restorations Resistant to Whitening
When used properly under the guidance of a Columbus cosmetic dentist, teeth whitening is safe for your teeth. However, in some cases, teeth-whitening compounds (usually a form of peroxide) can have a negative effect on your restorations.
Teeth whitening compound can cause some restorations to:
Peroxide will attack the molecules in the bonding cement, which can weaken the bond between your tooth and the restoration. This can cause your restorations to come off. This is a risk with most types of bonding cement, so it’s important to limit the amount of whitener you get behind your restorations.
Whiteners can attack the surface of some restorative materials. Like acid, this etches the material, giving it a rough surface. The rough surface causes it to lose its shiny luster, may make it feel “fuzzy,” and may make it more susceptible to staining.
Even worse, the whitener can soften your restorations. This will make them more likely to break or wear, leading to early failure. Composite restorations are the most susceptible to this, but some ceramics are, too. The most resistant materials are lithium disilicate and zirconia, so ask for these types if you expect to do a lot of whitening after you get your restorations (see “staining habits” below).
