It's not that cut and dry. Just because you have a small carie doesn't mean it's only going to get worse. That's the reason for fluoride in our water, in our toothpaste and in the wax the dentists applies at the end of your cleaning (that for some reason, insurance never wants to pay for).
Fluoride treatments and good dental hygiene can reverse carries. Carries should only be treated if they're large, or if they're still growing after discovery and alerting the patient.
