What causes bitter chemical taste in the mouth after root canal?
Patient: I have a bitter chemical taste in my mouth after the first stage of a root canal filling. Is this normal? Is it due to the chemicals used to clean the tooth or not all of the infection was removed and it is leaking into my mouth? The taste isn't removed with eating,  drinking or mouthwash. Doctor: Hello.Read through your query and accordingly I must say that it is just usual to have change in taste after the rootcanal trearment.Its due to the medicines used to clean the tooth and oral cavity.It will be reduced gradually within few days after treatment.You should drink lots of water and also do chlorhexidine mouthrinse so that it will be tasting little pleasant.Hope you are benefitted something from this reply.Have a healthy day!!!
