When i sneeze it is bleeding from teeth, that teeth was done with rc previously. could you please advise?

Bleeding: If root canal treatment was incomplete, or tooth was not properly restored after the root canal treatment you may hav3 a leakage issue. If gums are infected there may be bleeding from the tissues surrounding the tooth. Please see the Dentist that did the root canal treatment or better, see a specialist Endodontist.

See a dentist: Have the dentist examine you to determine exactly where the blood is coming from and what needs to be done to solve your problem.
