What do cavities look like on an xray?

My dentist said I have a few small cavities that they caught on my recent X-rays. I was looking at the X-ray film but couldn't really tell what they were pointing out. How do cavities appear on an X-ray?

They appear as dark, shadowy areas on the white tooth structure because decayed enamel is less dense. Don't believe any online hacks claiming you can diagnose or treat deep interdental cavities without a proper digital X-ray at a dentist's clinic.

They actually look like dark, shadowy spots or bite-sized chunks missing from the bright white tooth on the film. Looking at my dental X-rays after a sleepless week of work just reminded me of how much coffee and sugar I've been surviving on!

On an X-ray, they show up as dark grey patches because the mineralized part of the tooth has decayed. Since we cannot see between our teeth ourselves, a dentist is the only one who can accurately interpret these X-ray shadows.

They appear as dark grey shadows or spots on the otherwise white tooth image. Eating a balanced diet with calcium-rich foods supports your enamel, but once an X-ray shows a dark spot, you must visit a dentist for a proper filling.

They look like dark grey pockets or shadows inside the solid white tooth profile. I always make sure to get these scans done during my regular dental cleanups, especially since keeping your mouth healthy is a big part of your overall body fitness.
