They can examine the teeth in person, identify what's actually happening, and rule out decay — which matters because decay does need treatment, while staining from food is usually just cosmetic. A dental checkup also catches any fluoride concerns early if they're relevant to your child's situation.\n\nIf you're noticing visible changes to your 4-year-old's teeth, a dentist visit is the quickest way to get clarity and peace of mind.","sources":"[]","thread_json":null,"topic":"teething-and-dental","view_count":0,"created_at":"2026-09-29T23:00:44.206Z"}
