I had very white teeth and was ready to take the next step in improving my smile by getting a smile makeover. I spoke to my dentists and he suggested six porcelain crowns on my upper front teeth. I selected the whitest color available to me. Yet, when the crowns were put in, they did not seem to be the whiteness I had intended for them. Now, to top it all off, the dental crowns are starting to turn yellow. I haven’t even had these a year yet. Can I whiten them along with my teeth? How do I keep them from turning yellow again?
First, I want to make sure your dentist is using the updated shade guide. Before teeth whitening, the whitest shade was B1. Now, with the popularity of teeth whitening, the shade guides have been updated and BL1 is now the whitest. That may be the issue with the color discrepancy.
That doesn’t, however, explain the new staining. If your crowns are truly porcelain crowns they should be very stain resistant as long as the glaze on the porcelain is intact. This leaves me to wonder if something happened during one of your dental appointments to damage the crowns. Two possibilities are if the hygienist used an acidulated fluoride or a power prophy jet.
With the acidulated fluoride, it will etch the surface of the crowns, leaving the crowns very susceptible to staining. The power prophy jet can remove the glazing, causing staining take place even faster. Unfortanately, teeth whitening only works on natural teeth, so that would not be a good solution for you. The first step is to find out if the glazing has been damaged. I recommend seeing a good cosmetic dentist who can examine your crowns and ask them to give you an idea of why these are picking up stains.
One other quick question. I’m curious as to why your dentist chose crowns for this smile makeover. The standard for that type of procedure is porcelain veneers because it removes much less tooth structure. Was there damage to these teeth that required crowns?
