The ideal timing for fissure sealant application varies based on tooth eruption:
- For primary molars: The best time is after the complete eruption of primary teeth, typically around age 3, when the child is comfortable sitting in the dental chair for treatment.
- For permanent first molars: These teeth usually erupt around age 6, making this the recommended time for sealing.
- For permanent second molars: The ideal time is around 11-12 years of age when these teeth emerge.
- For premolars: Sealant application should follow their eruption, typically between ages 9-12.
The average lifespan of fissure sealants is 10-12 years, though this may vary depending on the material used and individual habits.
Fissure sealants are recommended for all children, regardless of their cavity risk. However, it is important to note that in children with poor nutrition, a diet high in carbohydrates, and inadequate brushing habits, sealants alone are not sufficient to prevent cavities. Proper oral hygiene and a balanced diet are still essential.
