How To Make Saline Solution


Updated May 21, 2014

Saline solution is used to cleanse the mouth when you have a canker sore, a soft tissue laceration, are healing after oral surgery, and so on. Rinsing with warm salt water two to three times a day may help to relieve a toothache, because salt water works as an antiseptic to remove bacteria from the infected area.

Saline solution is easily prepared in your own home, and only requires two to three ingredients that almost everyone has on hand.

Prep Time: 12 minutes

Total Time: 12 minutes


  • 1 Teaspoon Salt
  • 8oz. Warm Water
  • 2 Teaspoons Baking Soda (Optional)


Start by bringing the water to a rolling boil, for 10 minutes. After boiling, leave the water to stand until it is cool enough to rinse with, but warm enough to completely dissolve the next two ingredients.

When cooled accordingly, place the salt in the water while gently stirring until the salt has been completely dissolved.

As an option, dissolve the baking soda in the water along with the salt.

Use the saline solution as directed, and discard any leftover solution.
