Hello: I had a cavity filled for a left-side bottom back tooth on about a week ago. The local anesthetic I received in the back jaw area has resulted in some swelling and stiffness to the point of problems opening my mouth wide, even to eat. I consulted with my dentist and I was told to exercise my mouth. Sincerely, Mike B.

  • Some times local anaesthesia causes muscle stiffness or trismus when it is administered or the infection is there. Your dentist is right. You should exercise your mouth muscle till the opening is normal or you can have difficulty in opening the mouth which can increase. Maintain good oral hygeine also. for more info on local anaesthesia you can visit the followinghttp://www.identalhub.com/article_local-anaesthesia-and-sedation-in-dentistry-416.aspx link....
