Can salt water rinse heal gum infection? (Does salt water help receding/swollen gums?)

If your gums are red, sore, and swollen, you may be wondering if simply swishing with salt water can treat infected gums. While salt water rinses have benefits, relying on them alone to cure gum disease would be misguided.

Gum disease happens when plaque bacteria cause irritation and infection of the gums and supporting structures.

It commonly progresses through these stages:

  • Gingivitis: Mild gum inflammation that causes swelling, reddening, and bleeding.
  • Periodontitis: More advanced infection affecting gum tissues and jawbone. Can cause receding gums and serious damage without treatment.
  • AbscessSevere infection of the gums and bone causing pus-filled pockets, pain, and swelling.

While a salt water rinse can provide temporary relief and contribute to reducing associated symptoms, it’s important to understand that it cannot fully heal a gum infection on its own. You must address the plaque bacteria buildup. So how does a salt rinse work?

The Antimicrobial Properties of Salt 

Salt acts as a gentle antiseptic by drawing out fluid through the process of osmosis. Swishing with warm salt water can help:

  • Temporarily reduce gum inflammation and pain
  • Cleanse between teeth and around the gumlines
  • Remove debris in periodontal pockets
  • Draw out excess moisture from gum abscesses

Salt water rinses work by promoting osmosis, which draws out excess fluids and can help reduce swelling temporarily.

However, gum infections involve bacterial buildup below the gumline and in periodontal pockets, which cannot be effectively addressed solely with a salt water rinse. It offers short-term relief but does not cure gum infections.

Does salt water help receding gums and swollen gums?

Yes, a salt water rinse can help provide some relief for both receding gums and swollen gums, but it is important to understand its limitations.

For receding gums:

Rinsing with salt water can help reduce inflammation and provide temporary relief for receding gums. The mild antiseptic properties of salt water can help soothe the gums and alleviate discomfort. However, it’s important to note that salt water alone cannot reverse or heal receding gums.

Receding gums often result from more complex issues such as gum disease, aggressive brushing, or genetic predisposition. To effectively address receding gums, it’s advisable to consult a dentist who can diagnose the underlying cause and recommend appropriate treatments.

For swollen gums:

Swishing with salt water can also be beneficial for swollen gums. The osmotic effect of salt water can help draw out excess fluids and reduce swelling temporarily. This can provide relief from discomfort caused by swollen gums. However, like with receding gums, addressing the root cause of swollen gums is essential for long-term improvement.

Swollen gums are often a sign of gum inflammation, which can result from factors such as poor oral hygiene, gum disease, or other health conditions. Consultation with a dentist will help determine the cause of swollen gums and guide appropriate treatment options.

How to prepare an effective salt water rinse

Preparing a salt water rinse for mild gum issues is a simple and cost-effective way to provide temporary relief. Here’s how you can make and use a salt water rinse:

  • Gather Your Ingredients: Ensure you have warm water and table salt ready (preferably non-iodized)
  • Measure the Ingredients: For a salt water rinse, you’ll want to use about half a teaspoon of table salt for every 8 ounces (240 ml) of warm water. This creates a balanced solution that is not too strong.
  • Dissolve the Salt: Add the measured salt to the warm water and stir well to dissolve the salt completely. You can use a clean spoon for stirring.
  • Swish and Rinse: Take a small sip of the salt water mixture and swish it around your mouth gently. Tilt your head back slightly and let the solution reach all areas of your mouth, including your gums and the back of your throat.
  • Continue swishing the solution for about 30 seconds to one minute. Avoid gargling, as this can cause discomfort.
  • Spit Out the Solution: After swishing, spit out the salt water solution into the sink. Do not swallow it.
  • Rinse with Plain Water: Rinse your mouth with plain water to remove any residual salt taste.
  • Repeat as Needed: You can use a salt water rinse a few times a day, especially after meals and before bedtime. However, do not use it excessively, as excessive salt exposure may have adverse effects on oral tissues.


  • Make sure the water is comfortably warm, not too hot.
  • Use table salt without iodine or additives.
  • If you’re concerned about the taste, you can add a drop of natural mouthwash or a small amount of honey to the mixture for flavor.
  • A salt water rinse should not replace regular brushing and flossing or professional dental care.

When to See the Dentist

While salt rinses can supplement your oral care routine, visiting the dentist when you notice symptoms is critical to treat gingivitis or periodontitis before major damage occurs.

Signs that require professional dental care include:

  • Swollen, bleeding gums
  • Persistent bad breath
  • Receding gum lines
  • Loose or shifting teeth
  • Pus pockets around teeth

Treating gum infections requires:

  • Deep cleanings to remove plaque below the gumline
  • Antibiotics or antimicrobial rinses and other medication
  • Dental surgery to clean and reshape gum tissue

Don’t wait when suffering from gum infections – a salt water rinse can support healing, but is no substitute for professional treatment. Partner with your dentist to resolve gum disease.

Final Thoughts

While salt water rinses can offer temporary relief, they should be viewed as a supplementary measure to good oral hygiene practices and professional dental care. If you experience persistent issues with receding or swollen gums, seeking advice from a dental professional is recommended for proper diagnosis and treatment.
