I've never seen anything like it.

I had my wisdom tooth pulled and I know there was an infection but what is this black/grey sand like substance that was under my gums aheared to it?

It Is forming on the surfaces of the tooth growing out not in like a typical cavity.

is this a cavity? getting braces this month

I realise I have a big cavity on my tooth (currently waiting to see dentist), but i am just wondering does anyone have any idea if there is a possibility this tooth could be saved?

Thanks in advance for your help!

Just noticed this today and thought it was a popcorn kernel, tried to use my nail to get it off and that definitely hurt. It doesn’t hurt to eat or drink though, or just on its own it’s fine. What could this be?

I do floss and water floss once and brush twice a day, am I not doing a good job at it? I don’t drink anything besides water acidic food rarely last time deep cleaning ,may, my dentist insisted that I don’t have enamel problem or boneloss problem I’m so scared of gum disease since 2024 it’s been like this red and puffy gums it’s gets better a little after deep cleanings but never fully recover

So I was just brushing my teeth like normal and noticed a weird black line near my gums in the mirror. Idk what it is. Googled it, but couldn't really find an answer. Does anyone know what it could be?
