Study notes
A 7-year-old boy named Sam comes in because his lower front adult tooth is growing behind his baby tooth. This looks like 'shark teeth.' The dentist looks at the 'chronology' and sees the baby tooth should have fallen out by now. Diagnosis: Retained Deciduous Tooth (the baby tooth didn't shed). Treatment: The dentist gently numbs the area and removes the baby tooth. This clears the path for the adult tooth. Follow-up: Two months later, the tongue's natural pressure has pushed the adult tooth forward into its correct spot.
