A tingling, numb lip and tongue for a few hours after tooth removal is very common. Knowing the normal time helps you feel at ease and recognise when to speak up.
- A numb lip and tongue for a few hours after extraction is normal because the anaesthetic has not worn off, usually within two to four hours.
- While numb, do not eat or chew and avoid biting the lip, cheek or tongue.
- Numbness lasting beyond 24 hours or getting worse is a reason to tell the dentist.
- After the numbness fades, eat soft cool food and care for the socket as instructed.
Leaving the clinic after a tooth is removed, many people find the lip, cheek or tongue still numb, speech slightly slurred and water dribbling when drinking. This feeling is usually just the anaesthetic that has not worn off, but a few things are worth knowing.
How long is numbness normal?
Anaesthetic usually wears off gradually within about two to four hours after the procedure, sometimes a little longer if the lower jaw was numbed. The lip and tongue lose feeling, and as feeling returns there may be a tingling or mild prickling before things go back to normal. You may also read whether anaesthetic for extractions and fillings is safe and how long it lasts.
What should you do while still numb?
- Do not bite or chew on your lip, cheek or tongue, since you cannot feel pain and can injure them easily.
- Do not eat hard or hot food. Wait until the numbness is gone before eating normally.
- Sip water in small amounts and avoid very hot drinks that may burn without you noticing.
- For young children, parents should watch that they do not bite their lip or cheek.
When is prolonged numbness a concern?
Rarely, especially after removal of a lower wisdom tooth, the nerve close to the root is irritated or pressed so the lower lip, chin or tongue stays numb longer. Most cases recover gradually, but you should tell the dentist if:
- The lip, chin or tongue is still numb after 24 hours.
- The numbness is not fading and seems to be getting worse.
- It comes with a lot of pain, large swelling or fever.
The dentist will check and advise how to monitor it. You may also read how long bleeding lasts after tooth extraction and when to return.
Care once the numbness is gone
When the numbness has worn off, eat soft, cool food and care for the socket as instructed. See what to eat after a tooth extraction for faster healing.

Frequently asked questions
How long does a numb lip last after a tooth extraction?
Usually about two to four hours, once the anaesthetic wears off. It may last a little longer when the lower jaw was numbed.
Is it a problem if the lip is still numb the next day?
If numbness remains after 24 hours or is getting worse, tell the dentist so you can be checked. Rarely, a nerve near the root is irritated and causes longer numbness.
How can I avoid biting my lip while numb?
Do not eat until the numbness has gone, sip water in small amounts and watch young children so they do not bite their lip or cheek.
