With most local anaesthetics, your tooth will be numb for 2-3 hours, while your lips and tongue will be numb for 3-5 hours after the time of injection. As the blood flow carries away the anaesthetic from the injection site to be metabolized or broken down, the numb feeling will gradually fade away.
Dental anesthesia is a common and safe procedure, but before its administration, the dentist should know a patient’s complete medical history to avoid any possible complications.

“It’s a reversible coma, but it’s nevertheless a coma,” says Emery Brown, a professor of anesthesiology at Harvard Medical School and coauthor of the paper. General anesthesia before major surgery dips brain activity (as measured by electroencephalogram, or EEG) down to levels akin to brain-stem death.
Ingestion of lidocaine can cause numbness of the mouth and throat, which can lead to trouble swallowing and even choking. If a substantial amount is ingested , enough can be absorbed into the bloodstream to affect vital organs, primarily the brain and heart.
Early symptoms are circumoral numbness , tongue paresthesia , and dizziness . Sensory complaints may include tinnitus and blurred vision . Excitatory signs, such as restlessness, agitation, nervousness, or paranoia, may progress to muscle twitches and seizures.
Now, two startling studies suggest that the effects of anesthesia linger for a year or longer, increasing the risk of death long after the surgery is over and the obvious wounds have healed.
