7.  Gargle a salt solution

Gargling with a salt solution can also help. It is simple, just dissolve a small amount of salt in a glass of warm water, then take a sip of the solution and swish it inside your mouth for around 30 seconds and then spit it all out. Repeat the procedure for several times. Salt water acts on reducing the swollen gums and takes out the infection out of any abscess. You can incorporate this mouth wash in your daily brushing routine.
