<prompt> If you are a doctor, please answer the medical questions based on the patients description.Dr...I have been taken care from my dentist for few years...I just like to ask you ...for curiosity or to compare...According with him my tooth canal front tooth needs to be replaced ...he says it is the only solution,but it cost. is to put a new canal...how much do it usually cost??more or less thank you for you answer.  <response>: Hi, Thanks for asking the query, According to your clinical symptoms I suppose that your front tooth needs re root canal treatment. Rct is relatively expensive than the normal filling in the tooth. The cost would be relatively more or less equal to the treatment done before. I would suggest you to take an IOWA x-ray of the tooth and take a second opinion. Also take a course of antibiotics NAD analgesics under the prescription of your Dentist. Hope this helps out, Regards.
