What can I do about my front tooth? It is rotting from the top; how can I fix this and what would it cost? (Photo)

From what I see, you have 2 issues with that area. First, there probably is a cavity on the root of your tooth. That's an easy fix by removing the decay, followed by putting a tooth colored filling there. The other issue is the the tooth has a significant amount of gum recession on it and that's one reason why the tooth decayed as well. That problem should  be addressed also. The filling might cost several hundred dollars, depending on the dentist. the more significant fee would be for the gum treatment. You might even need to see an Orthodontist, too. ( Sorry about answering your question and more)

Hi and Thank you for your question:

It appears from the photograph that you have decay that is affecting the root of tooth #6 (canine). The location of the decay is such that it would be difficult to correct and it may even mean getting a root canal and therefore a crown afterwards. The recession of the gum those not help and because your smile line is high this would cause a significant esthetic defect. My suggestion would be to remove the tooth and place an Implant in an appropiate location. Please visit an Oral and Maxillofacial Surgeon for consultation regarding the implant and your dentist for crown on implant. Good Luck to you from your friendly Oral Surgeon!!!

Great Question--the dark area looks to be decay at the gum line--this should be easily restored with tooth colored composite --fees vary with the dentists office. Good luck!
