3. Use saltwater mouthwash.
Add 1 tsp of sea salt to a cup of lukewarm water. Stir to dissolve the salt. Swish a sip of it in your mouth for about 30 seconds and spit it out. Do this 4-5 times. And do it twice a day, once in the morning and once before bed. Saltwater reduces swelling in the gums, and aids in stopping gum bleeding. It also creates a temporary high alkaline environment inside the mouth thereby making it difficult for bacteria to survive.
4. Try an oral irrigator.
An oral irrigator is a device that shoots water jets to clean the gums thoroughly. You can also add mouthwash to it for better antibacterial effect. Having the gums clean reduces the chances of infection that can make your gums bleed.
