Introduction

In general, pit and fissure sealants can last for 3 to 5 years. After applying the sealants, parents should encourage their children to develop good oral hygiene habits and reduce consumption of overly hard or sticky foods. It is recommended to bring the child for a dental checkup every six months to one year to examine whether the sealants remain intact. If the sealants are found to be脱落 or damaged, they should be reapplied promptly to maintain their protective effect.

Generally, pit and fissure sealing can last for 3-5 years. Detailed analysis is as follows:

If children frequently consume excessively hard or sticky foods, such as nuts and candies, in their daily diet, these foods can continuously rub and pull on the sealant, causing it to gradually wear or fall off. In such cases, pit and fissure sealing typically lasts about 3 years. Additionally, inadequate oral hygiene and long-term accumulation of food debris at the edges of the sealant may accelerate the wear of the sealant.

If children avoid biting hard or sticky foods with sealed teeth and maintain good oral hygiene, including brushing teeth morning and night and rinsing after meals, reducing erosion of the sealant by food debris, the wear rate of the sealant will significantly slow down. In such cases, pit and fissure sealing generally can last up to 5 years. Regular dental checkups to promptly detect and address minor damage to the sealant also help extend its longevity.

After pit and fissure sealing, parents should encourage children to develop good oral habits and reduce consumption of overly hard or sticky foods. It is recommended to schedule a dental checkup every six months to one year to ensure the sealant remains intact. If the sealant becomes detached or damaged, it should be repaired promptly to maintain its protective effect.
