I had damage to a tooth and now it needs a dental crown. My dentist is having trouble matching the crown, because all the crown colors are darker than my teeth. He says I’ve overbleached my teeth. I did get them whitened about six months ago. My dentist doesn’t do whitening (or any cosmetic work) so I went to another practice and had Zoom Whitening done. Now my dentist said that is why my crown won’t match. Is this true? I find it hard to believe that no one who whitens their teeth needs a crown done.
The problem you are facing here is your dentist doesn’t have enough knowledge about cosmetic dentistry. He probably felt his general dentistry training was enough. After all, creating a dental crown is pretty basic dentistry. The problem is not that you have whitened too much. It is that he does not understand how teeth whitening has to be factored into your crown creation.
Dentists typically use a smile shade guide, such as the one above to match a crown to existing teeth. This worked fine for many years. And then came teeth whitening…
When you whiten your teeth, the gel doesn’t just whiten away stains, it also whitens your natural tooth structure, which will enable your teeth to be whiter than even the whitest shade on the guide. Dentists who saw a lot of whitening patients realized they’d need a better shade guide, one that took into account the new more popular colors people were getting.
To accommodate that, a new shade guide was developed with some whiter additions. Your dentist may not even be aware it exists. This is the type of shade guide needed to match your dental crown.
