Yesterday I had a cavity filled on the bottom left side of my mouth. The dentist gave me the usual shots of anaesthesia and all was well. Today he had to fill a cavity on the bottom right side on my mouth, but the anaesthesia just wasn’t kicking in. After a few shots he said he can’t give me anymore anaesthesia and we rescheduled for another day.
Any idea why anaesthesia would work one day and not work the next day?
Edit: I should mention that my tongue went numb, but not the area around my teeth.

The anaesthetics given to you buy the dentist is a fairly low power drug that have to be administered directly to the nerve cluster. If the dentist miss and inject it elsewhere then it is not going to have any effect and will just be distributed harmlessly through your body in a very dilluted form over the next few hours. That is the most likely case. He probably just missed the nerve cluster.
