How to Rinse With Salt Water After a Tooth Extraction

A tooth that is chipped, rotted or otherwise damaged beyond repair is removed by a dentist or oral surgeon via extraction 2. A similar procedure is also used to eliminate unnecessary wisdom teeth from the mouth. While a tooth extraction is a simple procedure, patients still experience discomfort and are also at risk for infection once the tooth is removed 2. Rinsing with salt water on a daily basis after the extraction prevents infections, heals cuts and other wounds and speeds up overall recovery time.

Wait 24 hours after the extraction before rinsing. This keeps you from experiencing severe pain while rinsing.

Repeat Steps 2 through 5 right when you wake up, after each meal and right before you go to bed to avoid infection.


Rinse your mouth with salt water for a week or two, or as directed by your dentist or oral surgeon, to avoid infections and speed up healing time.

Remember to drink plenty of fluids (if/when your doctor gives you the OK to do so), as rinsing with salt water dries out your mouth and skin.


Contact your dentist or oral surgeon if you experience excess pain, bleeding or swelling or any high fevers 48 hours after the extraction.
