I am getting a dental crown on a white tooth and I want to do a touch-up on my teeth whitening before I get it. I asked my dentist how long I would have to whiten my teeth each day and for how many days to get them back to their original color when I first whitened them three years ago. He couldn’t tell me so I am wondering if there are some tips you have.

Dear Bethany,

 

I am going to help you with this, but before I do I want to let you know that I am concerned that your dentist was unable to answer these type of questions. Teeth whitening is a fairly straightforward procedure. If he can’t deal with that I would not trust him to place a dental crown on your front teeth. We’ll go over how to find a dentist who can in a moment.

The Basic Principles of Teeth Whitening

The main idea behind whitening your teeth is the longer you wear the whitening gel, the faster your teeth will whiten. You can wear them one hour a day, but they whiten faster than if you wear them several hours a day or overnight. Because each person’s teeth are different in the amount of staining and how white they want them, there is no way to quantify a number of days/hours. The one constant is you want to leave a week between when you stop your teeth whitening and when you begin the procedure for your dental crown. This is because the teeth will continue to whiten during that time period.

Getting a Crown on a Front Tooth

Crowns on back teeth are no big deal. The color doesn’t have to match exactly. However, matching a single crown to a front tooth is a completely different story. All the light hits your front teeth making all the differences much more visible. Even the best cosmetic dentists will do a couple of try-ins before settling on it being just so.

Ideally, you would want an expert cosmetic dentist to do this. Look for a dentist who is AACD accredited. Then you can be certain they will get it right. If your dentist cannot tell you about teeth whitening, I would not let him near this crown.
