RCT Local Anesthetic causes TMJ?
My husband went in for a root canal.
The dentist gave him a shot in the inside of his cheek. A week later, he can not open his mouth very well to even eat. He went back and told the dentist.
The dentist said he now has TMJ. He has never had problems until he received that shot. Seems like a muscle in his jaw was messed up.. ...Visitor from LA
The shot inside the cheek can cause trismus or a spasm of the muscle fibers caused by the injection.
It will subside eventually and advil type non-steroidal anti-inflammatories and moist heat will help.
If the source of the pain is from the TMJ it is most likely from having his mouth open for a
prolonged period of time during the root canal procedure. This will usually subside over time as well with anti-inflammatories, soft diet, heat and time.
Follow up with your dentist - a shot won't cause TMJ problems..
