Introduction

In general, pit and fissure sealing does not affect tooth replacement. If discomfort occurs, it is recommended to seek timely treatment at a qualified hospital. After undergoing pit and fissure sealing, care should be taken to avoid biting hard foods with the sealed teeth to prevent the sealant from becoming dislodged. Daily tooth brushing should be maintained to keep the mouth clean, and regular check-ups are needed to ensure the sealant remains intact. If the sealant becomes脱落 (dislodged), prompt reapplication is advised.

Generally speaking, pit and fissure sealing will not affect tooth replacement. If discomfort occurs, it is recommended to seek timely treatment at a regular hospital. Detailed explanation is as follows:

Pit and fissure sealing involves applying a layer of sealant onto the pits and fissures of the tooth surface to form a protective membrane. Its function is solely to prevent dental caries and it does not invade the internal structure of the teeth, nor does it affect the development of the tooth roots or alveolar bone. For children who have undergone pit and fissure sealing on their baby teeth, the sealant will naturally fall off along with the normal shedding of primary teeth, without hindering the position or timing of permanent tooth eruption. After pit and fissure sealing on permanent teeth, the sealant bonds closely to the tooth surface, does not interfere with the normal growth and replacement process of teeth, and therefore does not negatively affect tooth replacement.

After undergoing pit and fissure sealing, one should avoid biting hard foods with the sealed teeth to prevent the sealant from falling off. It is important to maintain daily tooth brushing and oral hygiene, and to periodically check whether the sealant remains intact. If the sealant becomes detached, it should be reapplied promptly. Moreover, even after pit and fissure sealing, attention should still be paid to the tooth replacement process, and any abnormalities should be reported to a dentist as soon as possible.

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.
