I’ve been getting these dark lines at the top of my teeth, near the gumline. It’s on all the teeth that have dental crowns. Will teeth whitening solve this problem?

Stacy,

Unfortunately, the problem isn’t your teeth, it’s your crown. You can’t whiten dental crowns using teeth whitening. It sounds like your dentist gave you porcelain fused to metal crowns. Eventually, they all develop a dark line at your gumline.

The only way to fix this problem is to get new crowns. This time get all porcelain crowns. They’ll be more natural looking and you won’t get a gray line. However, because you realize that dental work can’t get whitened, you might consider getting your teeth whitened before you re-do the crowns. Then, you can get the all-porcelain crown to match your new sparkly white smile.
