How dentists really find decay
Early decay starts as a chalky white spot, then turns brown and finally becomes a hole. At the white-spot stage it can often be stopped with fluoride and better cleaning.
Decay between teeth cannot be seen in the mirror. On an X-ray it shows as a dark shadow because the softened tooth lets more X-rays pass.
Small cavities usually need only a simple filling. Waiting until a tooth hurts often means a bigger treatment — regular check-ups keep it small.
