Hello Dear,
I have gone though your query, I will try to give my best possible advice. I have gone through your query.
A
root canal treated tooth is like a tree with no nutritional supply since all the nutritional supply of the tooth is cut during RCT.
So to compensate this and to withstand the biting forces and to provide adequate strength, an additional support i.e. crown is recommended for root canal treated teeth.
• An infection may occur in a root canal treated tooth if there is lack of proper apical seal in the roots of that tooth and marginal leakage in the restoration.
Infection may also occur due to compromised periodontal condition of the tooth.
• In such cases ussually retreatment followed by crown is indicated.
•I advice you to get an appointment with the
dentist as soon as possible and get a thorough clinical and radiological examination so that he/she can start the needful treatment.
• Hope this will help you. If there is any more query or question regarding this in your mind, you are welcome to ask me any time.
Take Care
Regards
