I had a root canal on my front tooth, my dentist put a crown over it. It's nice and the newest type of crown no black showing around the tooth except on top of the tooth. My dentist said that's because of the root canal that my tooth turned black. Is there anything he can do for that not to show? thank you.
Answer: Replacement of crown There are a few things to consider. Roots of teeth sometimes turn dark (even turned black), so even the gum tissues on top may shift color. Nothing can really help with that. The crown can be replaced and the edge of the crown can be put below the gumline, but gums may recede and reveal the root again anyway. There is also a method to trough internally and bond a white material that will "shine thru like a contact lens" to lighten the root internally. This works well, but DOES require replacement of the crown.I generally suggest NOT doing this, as the tooth has been weakened from the root canal therapy and may fracture when replacing the crown.

Answer: Black showing on top of crown When a tooth has a root canal then it can be discolored internally and can show through. There is an internal bleaching procedure that can lighten it up so that it shows less. Or if the tissue is very thin where it shows through then the tissue can be thickened with a graft and that may make it less obvious. Good Luck!

Answer: Black Line Above A Crown It is true that your tooth can turn very dark following a root canal. There are a few reasons that you may have that darkness at the gumline.

Answer: Black root showing The only practical way to improve the appearance is to lighten the shade of the tooth. The way to do this is to do internal bleaching, which involves placing whitening solution inside the root of the tooth and sealing it in and letting you walk around over a period of a few days. This will unfortunately involve damaging your crown if you were to request it now, so I normally do this whilst the temporary crown is in place. Attempts to simply make the crown longer to cover more of the root always fail because the higher up the root you go, the darker it tends to get. Some recession (the gum moving away from the crown) is almost inevitable and so this way there will always be a black line - but only higher up the root. Good luck with whatever you decide to do -Kind regardsThomas Dey, BDS, MSc
