Is this a cavity?
Tooth #7 was shaved down and is mainly a composite now that’s why it’s short (it’s not showing here since I believe they used the composite that doesn’t have the radiopaque element yet when they placed it) - I have a bit of recession because of braces as well.
This tooth has been bothering me so much, I’m starting to see brown spots inside my gum on my tooth and it is incredibly sensitive to cold air/water. And I mentioned this before to my dentist but they brushed it off and said it’s just a stain though it’s starting to look like a decay to me. I’m curious because there’s a huge triangle in that area and the composite has been 7 years now. I see minimal plaque on the mesial side but I’m wondering if that dark part is cavity?
