Introduction

In general, pit and fissure sealing can prevent dental caries. If you have any questions or discomfort, it is recommended to consult a professional dentist promptly. After undergoing pit and fissure sealing, avoid chewing excessively hard foods on the treated side for a short period to prevent the sealant from dislodging. It is important to maintain good oral hygiene by brushing teeth thoroughly on a daily basis, and to visit the hospital regularly for check-ups to ensure the sealant remains intact. If the sealant becomes dislodged, it should be reapplied promptly.

Generally, pit and fissure sealing can prevent dental caries. If you have any questions or discomfort, it is recommended to consult a professional dentist promptly. Detailed explanation is as follows:

The principle of pit and fissure sealing involves applying a specialized sealing agent onto the pits and fissures of the tooth's occlusal surface, forming a protective barrier. Deep pits and fissures tend to accumulate food debris and bacteria easily, which are difficult to clean thoroughly through regular brushing, leading to dental caries over time. After the sealing agent solidifies, it isolates food particles and bacteria from contacting the pits and fissures, preventing acid production by bacteria that can erode the tooth structure, thus reducing the likelihood of developing caries. This procedure is simple, does not damage dental tissues, and is suitable for children after their permanent teeth erupt, providing long-term protection for the teeth.

After pit and fissure sealing, avoid chewing hard foods on the sealed side for a short period to prevent the sealant from falling off. It is important to brush teeth thoroughly in daily life, maintain good oral hygiene, and regularly visit the clinic to check if the sealant remains intact. If the sealant becomes detached, it should be reapplied promptly. Even after undergoing pit and fissure sealing, maintaining a healthy diet and reducing intake of sweet foods are still necessary to lower the risk of dental caries.

When should pit and fissure sealing be done?

In general, pit and fissure sealing is performed within one year after the tooth erupts. After undergoing pit and fissure sealing, certain precautions should still be observed. For several days following the procedure, avoid chewing excessively hard or sticky foods with the sealed teeth to prevent dislodgement of the sealant material. It is important to maintain good oral hygiene by thoroughly brushing teeth twice daily and using dental floss or other tools to clean the interproximal surfaces of the teeth.
