Gums in two of my lower front teeth have risen. Why?

Hi,

Welcome to icliniq.com.

That condition of your gum is called localized gingivitis. It occurs because of the deposition of calculus and plaque on your teeth and inside the gums margins, which causes inflammation of gums that enlarged in size.

The first treatment is ideally you should visit a dentist and get the scaling, cleaning, and polishing done. Once your teeth and gums get cleaned, after you will have to maintain your hygiene, then after a few days it will become totally fine.

Right now at home you can do proper brushing and flossing and do warm saline i.e. warm water and salt rinses daily, it will heal slowly, but scaling is genuinely required.

I hope this helps.
