Recovery After Wisdom Tooth Extraction: Bleeding, Brushing, Meals and Daily Precautions

The key to recovery after wisdom tooth extraction is protecting the blood clot that forms in the socket. In Korea, the Korea Disease Control and Prevention Agency (KDCA, 질병관리청) advises biting gauze firmly to stop bleeding, not using straws for 3 days, brushing around the surgical site for 1 to 2 days and not chewing on that side for about a week. Pain peaks in the first 1 to 2 days and swelling around 48 hours, and if symptoms get worse instead of better after 3 days, infection is suspected and you should return to the dentist.

What should you observe on the day of extraction?

Right after extraction, bite the gauze firmly and talk less. The KDCA wisdom tooth guidance says to keep it in for about 30 minutes and the general extraction guidance says about 1 hour 30 minutes, so there is a difference; just follow the time your dentist gives you. It is better to swallow blood and saliva in the mouth rather than spit, since frequent spitting creates pressure in the mouth and can prolong bleeding.

Do not use a straw for about 3 days, and do not touch the extraction site with your tongue or fingers. If the blood clot comes loose, bleeding stops later and the risk of infection rises. Until the anesthesia wears off it is easy to bite your cheek and tongue, so avoid hot or hard food. Blood may show for about a day after extraction, and occasional blood after meals or brushing can continue for about a week.

When can you start brushing and rinsing?

For 1 to 2 days after extraction, brush only the other teeth and avoid the surgical site, then begin to brush gently around the extraction site. Rinsing the mouth hard can dislodge the blood clot, so for the first few days only hold water lightly and let it out.

Even if food gets caught in the extraction socket, do not dig it out with a toothpick or finger. If trapped food keeps bothering you, it is safer to ask the dentist to irrigate it at your follow-up visit.

What should you eat and what should you avoid?

The KDCA advises avoiding chewing on the surgical site for about a week and eating soft, non-irritating food. The general extraction guidance explains that soft, cold food is best for the first 12 hours. Rough or hard food can interfere with wound healing or restart bleeding.

First 12 hours: cold, soft food
First week: easy-to-chew food such as porridge, steamed egg or tofu, chewed on the opposite side
Avoid: hot, spicy or salty food, and hard or crumbly food such as nuts
Avoid: drinks through a straw, and alcohol

What should you be careful about in daily life?

Depending on the extent of surgery, resting for 1 to 2 days is advisable. The KDCA advises avoiding hot baths, saunas, strenuous exercise and work during this period, because a sudden rise in circulation can make the clotted site bleed again.

Smoking and drinking slow early recovery and can lead to complications such as infection, so the KDCA advises avoiding them for about 7 to 10 days after extraction. Sleeping with your pillow slightly higher than usual helps reduce swelling. The prescribed medicine is usually 3 to 5 days' worth, and you should take it as directed even if you feel better.

When should you go back to the dentist?

Pain is usually strong for 1 to 2 days and then gradually fades. If the pain is severe even with medication, see the dentist even before your appointment date. The KDCA explains that infection should be suspected if pain or swelling increases, or if difficulty opening the mouth continues, after 3 days.

Visit the dentist immediately if your face is badly swollen and your mouth barely opens, if it is hard to swallow, or if you have chills and fever with pain deep in the throat. If severe pain returns with a bad smell around days 3 to 5 after extraction, it may be dry socket (alveolar osteitis).

Common myths and facts

Myth: After extraction, you must keep spitting out the blood for it to stop sooner.

The KDCA advises swallowing blood and saliva. Spitting repeatedly can instead prolong bleeding because of pressure in the mouth.

Myth: Once the pain fades, you can stop taking the prescribed medicine.

Prescribed medicine is usually 3 to 5 days' worth and is best taken as directed. If you want to change how you take it, ask the dentist first.

Myth: You can exercise as usual from the day after extraction.

The official guidance is to rest for 1 to 2 days depending on the extent of surgery, avoiding saunas and strenuous exercise during this time.

Frequently asked questions

What if bleeding continues after I take the gauze out?

Place new gauze on the extraction site and bite down firmly again to apply pressure. A little blood mixed in saliva is common, but contact the dentist if blood keeps pooling even after biting new gauze.

When can I go back to work or school after extraction?

It depends on the extent of surgery, but the KDCA recommends rest for 1 to 2 days. Seated work is often possible from the next day, but it is better to put off physical work for a few days.

When does the hole where the tooth was fill in?

The gum covers it over several weeks, and the bone underneath takes longer to fill in. Food may get caught in the meantime, so manage it by rinsing gently, and the dentist checks the progress at your follow-up.

Can I fly after extraction?

If a hole has opened into the maxillary sinus after an upper wisdom tooth was pulled, the KDCA advises avoiding sneezing and nose blowing for about 3 to 4 weeks. In that case, it is best to discuss flight plans with the dentist first.

Is it normal that my mouth does not open well?

The KDCA explains that difficulty opening the mouth after extraction often appears temporarily along with early swelling and resolves on its own. If it continues or gets worse, you should be checked for infection or a jaw joint problem.
