How do cavities look on x rays?

I was just reading about this and apparently, because decay makes the tooth less dense, X-rays pass right through it. That is why cavities look like dark, fuzzy shadows compared to the solid white of healthy teeth.

They look like dark spots on the scan. If your dentist recommends an X-ray, go for a local clinic where it costs just 200-300 rupees. Finding the cavity early on the scan saves you from the heavy cost of a root canal later.

I just saw my dental X-ray yesterday. The tooth looks bright white, but the cavity is like a dark gray triangular shadow creeping in from the side. It is super obvious once the doctor points it out.

They show up as dark, less dense areas on the X-ray. Since managing thyroid issues can sometimes affect saliva flow and bone health, I make sure to get these dental scans done during my regular health follow-ups every year.

Seeing those dark spots on my X-ray made me feel so bad, like I had failed at taking care of myself. But the dentist explained that some teeth just have deep grooves. Seeing the dark shadows is actually helpful so we can treat it before it hurts.

Exactly, they look like dark shadows. Just trust what your dentist shows you on the screen.
