Dental Anesthesia

Novacaine Reaction



I went to the dentist a week and 1/2 ago for a procedure. When He was giving me the injection he said the syringe was leaking and asked for another one. I remember him swabbing the liquid from my tongue. Now, 8 days later I still have a tingling sensation on my tongue, not painful, but very uncomfortable. How long can I expect this to last and is there anything i can do?


This is unusual as there are rarely any permanent effects from local anesthetic topically applied, intentionally or otherwise, to the oral tissues. I would see your dentist to ensure there is not another concern here. This is unexpected.
