No it's not a cavity. The crown on your front tooth is a type called a PFM or porcelain fused to metal crown. The black line you're seeing is the area at the gum line where the porcelain gets very thin and you can see the metal showing through. Ideally if you do this type of crown in the anterior you prep the tooth with the margin deep enough under the gums that the line is hidden by the gingiva. (your gums). The only way to get rid of it is to have the crown redone with either full porcelain (which can sometimes not be possible depending on the tooth) or have it redone where the gum is placed subgingival.

Please add to your question and give us some answers to:
Which tooth is this?
Is the "crown" in question your natural tooth or an artifical crown that was placed on your tooth?
Where is the black line? How long is it?
How long has the black line been there?
How old are you?
When is the last time you had your teeth cleaned professionally?
Thanks. Someone will be able to give you a better answer if we have all of this information.

Decay and stains do not show up as lines.
If the live is vertical, its stain in a crazed part of the enamel. It does not always mean the tooth is cracked, & since your tooth doesn't hurt, it probably isn't.
A horizontal crack is usually the metal under a porcelain crown as the previous people said.
A black line can show up around a tooth colored filling, that means the filling is leaking and will need replacing soon.

Its the metal on the inside of the crown. If its a front tooth, they should have put an all porcelain crown on (more expensive but esthetics's are nicer). Your gums are receeding and starting to show the margins of the crown. Try to not brush so hard, you probably wont be able to get your gums to grow back over it but it will not get any worse.

Maybe I am misunderstanding, it is a crown on your tooth? If so that is normal for certain crowns. If it's on your natural tooth, you should go see your dentist before it does either hurt or hurt your tooth. Good luck and sorry I didn't get it the first time. Nana

If it is an actual "crown" around your tooth with a black line that is the metal substructure of the crown. porcelain crowns are baked to a metal substructure and the metal will show around the bottom of the tooth that is completely normal.

If it's what i think, it's definitely some form of tartar. A simple cleaning by a dentist will remove it.
It's nothing to be scared about. It's just that brushing does not always clean everything.

Some people get iron deposits on their teeth. It may not be a cavity. Depending on what you eat. If you take vitamins this may be it. Or if you eat things that are full of iron.

Sounds like labial decay. Do you drink lots of soda or coffee with sugar? Better see your dentist and get it fixed. And no more Mountain Dew!

Definitely a cavity. It may not hurt now but it will. You need to go to the dentist ASAP.
