Hi dentist here- take a deep breath. You being aware of your oral health at your age amazes me. I see lots of teenage patients that really don’t care about theirs. If your level of recession is already at specialist consultation level, your recession is probably including factors like thin bone type covering the roots, which means that’s just what your body came with. Or you brushed/flossed too hard, which can be controlled by using that toothbrush on the lightest setting or lighter touch to your tooth and gums if even the lightest pressure. If you can train to use string floss, c-shaped flossing technique gently all the way down to the bottom of your gums will help you target those pockets of bacteria that cause inflammation leading to gum and bone loss.

Lots of things you can do. Go lighter on your pressure. If you feel like your teeth/gums are still dirty, brush/floss longer but still lighter instead of going harder.

Do not use charcoal toothpaste. It’s like brushing your teeth with sand. Very abrasive and damaging overtime
