For the first 24 hours after wisdom teeth removal, you should not brush, rinse, spit, or use mouthwash at all. After that initial day, you can and should start cleaning your teeth again, but the extraction sites need special care for several weeks. The key to the whole recovery is protecting the blood clot that forms in each empty socket, because dislodging it leads to a painful complication called dry socket.
The First 24 Hours: Leave Everything Alone
This is the hardest part for most people, but it’s straightforward: do nothing to your mouth for the first full day. No brushing, no rinsing, no spitting, no mouthwash. The blood clots forming in your sockets are fragile, and any suction or swishing motion can pull them out. That dark, scab-like clot sitting in the hole is exactly what you want to see. Don’t touch it with your tongue or fingers.
If your mouth feels grimy, that’s normal and temporary. You can drink water, but let it flow passively rather than swishing it around.
Brushing After Day One
Starting on the second day, you can brush your teeth, and you should. Keeping the rest of your mouth clean actually helps prevent infection at the surgical sites. But there are a few rules to follow.
Use a fresh toothbrush or replace your brush head before that first post-surgery session. Your old brush harbors bacteria you don’t want near open wounds. Brush gently with soft bristles, and completely skip the extraction areas at the back of your mouth. You’re cleaning everything except the surgical sites. If pain or swelling makes even gentle brushing too uncomfortable, it’s fine to skip a day or two.
Once at least a week has passed, you can start very carefully cleaning closer to the extraction sites using ultra-soft strokes. Some people find a sterile cotton swab easier to control than a toothbrush near those areas. Be careful not to push any food debris deeper into the socket.
Salt Water Rinses: Your Main Cleaning Tool
Salt water rinses are the safest and most effective way to keep your extraction sites clean during recovery. A clinical trial found that patients who used warm salt water rinses had a dry socket rate of just 2.5%, compared to 25% in patients who didn’t rinse at all.
To make the rinse, dissolve 1 teaspoon of salt in 8 ounces of warm water. Start these rinses the day after surgery, and use them up to four times a day, including after meals. The warm temperature is intentional: warm saline was specifically studied and shown to be effective at preventing dry socket.
Here’s the critical technique: do not swish vigorously. Tilt your head and let the salt water soak the area gently, then let it fall out of your mouth. Aggressive swishing creates the same suction forces that can dislodge your blood clot. Even rinsing too hard with regular mouthwash can knock a clot loose. Think of it as bathing the area, not power-washing it. Interestingly, the same study found that rinsing just twice a day worked about as well as rinsing six times a day, so you don’t need to overdo it.
Mouthwash Restrictions
Avoid alcohol-based mouthwash during your recovery. Alcohol irritates the raw surgical tissue, causes stinging, and can delay healing. If you want to use a mouthwash beyond salt water, choose an alcohol-free antiseptic rinse. Your surgeon may also prescribe a chlorhexidine mouthwash for extra bacterial protection, and a fluoride rinse can help protect the rest of your teeth during the weeks when brushing is limited.
Whatever rinse you use, apply the same gentle technique: no forceful swishing, just let the liquid sit against the area.
Getting Food Out of the Sockets
Once your sockets start to open up after the clot shrinks, food will get trapped in them. This is one of the most annoying parts of recovery, and it can last for weeks until the holes fully close. Resist the urge to dig food out with a toothpick, your tongue, or anything sharp.
For the first week, salt water rinses are your only option for dislodging food. Tilt and soak, then let the water drain. After the first week, you can gently brush near the area with a soft-bristled toothbrush or a cotton swab, using very light pressure.
Using an Irrigation Syringe
Your oral surgeon may give you a curved-tip plastic syringe at your follow-up visit. This is the most effective tool for flushing food particles out of healing sockets. You typically start using it three to five days after surgery, but only when your surgeon tells you it’s safe. Fill it with warm salt water, position the tip near (not inside) the socket opening, and gently squeeze. The low-pressure stream rinses out debris without disturbing the healing tissue.
You’ll likely need to use the syringe after every meal until the sockets close, which can take several weeks for lower wisdom teeth.
Flossing and Normal Routine
You can resume flossing the rest of your teeth the day after surgery, as long as you stay away from the extraction sites. Keeping your other teeth clean reduces the overall bacterial load in your mouth, which helps your surgical sites heal faster. Use the same gentle approach you’re using with brushing: normal technique everywhere except the back of your mouth where the extractions happened.
Most people can return to their full oral hygiene routine, including brushing and flossing near the extraction areas, once the sites have completely healed. That timeline varies, but the soft tissue typically closes over within two to three weeks, and deeper bone healing continues for months beneath the surface. Your surgeon will let you know at your follow-up when it’s safe to treat those areas like the rest of your mouth.
