In your case, it is impossible to wash your teeth at one time. It is recommended to go once every six months.
Dental calculus can irritate the gums, and you have serious periodontal problems now. If you continue to stimulate for a long time, your teeth will fall out.
I suggest you wash your teeth first and get rid of tartar. As for your root, it will be exposed at that time, and it is hard to say that it will fall off. So it's better to wash it off anyway. After all, it won't irritate the gums after washing, and it won't necessarily bleed. It is recommended that the gums climb up after washing, pay attention to eating and don't chew.
Having said that, my advice to you is that you must brush your teeth ~! It won't hurt very much, but after all, you have to endure your severe pain. You are only 22 years old. I don't want to see you lose all your teeth because of tartar irritation. After tooth cleaning, apply iodine glycerin to the gums to reduce inflammation. Maintain good oral hygiene. I hope my answer is helpful to you.
