I took my 6 month old daughter in when I saw yellow spots in the enamel of her front teeth. The dentist advised that this was just a developmental error from inutero and advised that just continue care as usual. Six months later her father took her for a follow-up and she was diagnosed with Caries and recommended for surgery with full anesthesia for a cleaning and capping. We went to several other dentists following this recommendation and they each agreed that it was a developmental error from inutero and advised that just continue care as usual. Short story - these doctors are not beyond reproach. Always seek a second opinion before undergoing any drastic procedure like surgery.
