The short answer
Local anaesthetic usually leaves the mouth numb for a period after wisdom tooth removal, while sedation or general anaesthesia affects alertness for a separate period determined by the medicines used.
Why can the mouth stay numb after local anaesthetic?
Local anaesthetic blocks nerve signals around the tooth and may numb the lip, cheek, tongue, or gum. Sedation does not simply extend local numbness, so discharge instructions must cover both sensation and alertness.
What should you avoid while your mouth remains numb?
Do not chew while the lip or cheek is numb, and follow the clinic’s instructions about driving, supervision, food, and medicines after sedation. Ask when normal sensation and activities should return for your specific anaesthetic plan.
When does persistent numbness need dental review?
Contact the clinic if numbness is not improving as instructed, or if there is severe pain, swelling, breathing difficulty, or another unexpected symptom.
What should you ask about the anaesthetic and numbness?
Ask which anaesthetic was used, which tissues may be numb, what activities are restricted, and when the clinic wants you to report persistent altered sensation.
