Can you see cavities without x rays?

Actually, you can see some cavities if they are on the chewing surface as black or brown spots. But honestly, the ones hiding between your teeth are hard to spot without a proper checkup.

Yes, large cavities are easily visible to the naked eye when you look in the mirror. But for smaller, early-stage decay, a dentist's clinical exam is necessary so it doesn't grow bigger.

I also keep looking in the mirror with my phone flashlight worrying about spots. Yes, some are visible, but please don't stress yourself out too much trying to self-diagnose. Just get a quick dentist opinion to be safe.

I ignored a tiny black dot on my molar thinking it was nothing since there was no pain. Ended up needing a painful root canal later. Please go get it checked immediately even if it looks small.

Yes, my doctor showed me a cavity on my back tooth using a small dental mirror and camera. But for the tooth next to it, she had to do an x-ray because the gap was too tight to see.
