Introduction

If the pit and fissure sealing procedure is performed improperly, with inappropriate material selection or inadequate postoperative care, it may lead to several adverse effects. These mainly include secondary caries in the sealed area, irritation of oral tissues by the sealing material, impaired occlusal function, loss of sealant leading to failure of protection, and overreliance on sealants potentially causing other dental problems. When undergoing pit and fissure sealing, it is advisable to choose a qualified hospital and have the procedure performed by an experienced dentist.

Generally, if the pit and fissure sealing procedure is performed improperly, inappropriate materials are selected, or post-operative care is inadequate, some adverse effects may occur. These mainly include secondary caries in the sealed area, irritation of oral tissues by the materials, impaired occlusal function,脱落 of the sealant leading to loss of protection, and over-reliance causing other dental problems. Detailed explanations are as follows:

1. Secondary caries in the sealed area: If food debris and bacteria in the tooth fissures are not thoroughly removed during the procedure or microgaps exist between the sealant and the tooth margins, bacteria can continue to proliferate beneath the sealant, gradually eroding the dental tissues and causing secondary caries in the sealed area.

2. Irritation of oral tissues by materials: Some sealant materials may contain irritating components. If the material overflows onto the gums, buccal mucosa, or other areas during application and is not promptly cleaned, or if some individuals are sensitive to the material's components, it may cause redness, swelling, stinging, and other discomforts in the oral mucosa.

3. Impaired occlusal function: If the sealant is applied too thickly, the surface is uneven after curing, or the dentist does not adjust the occlusal height in a timely manner, a noticeable foreign body sensation or high occlusion may occur during biting. Long-term issues may lead to temporomandibular joint discomfort, such as joint clicking and facial muscle pain during chewing.

4. Sealant脱落 leading to loss of protection: If the tooth surface is not thoroughly cleaned, etching is insufficient, or hard or sticky foods are frequently chewed after the procedure, the sealant may wear down, chip, or even脱落.

5. Over-reliance leading to other dental problems: Some individuals may excessively rely on the protective effects of the sealant after undergoing pit and fissure sealing, neglecting daily oral hygiene practices such as reducing tooth brushing frequency or not using dental floss.

When undergoing pit and fissure sealing, one should choose a reputable hospital and have the procedure performed by an experienced dentist. Post-operative care instructions must be strictly followed, regular follow-up visits conducted, and improper procedures or care avoided to prevent complications and ensure the sealant effectively provides protection and maintains dental health.

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.

When should children receive pit and fissure sealants?

Under normal circumstances, children can receive pit and fissure sealing at the age of 6 to 7 years. After the procedure, it is important to avoid letting the child chew excessively hard foods, such as nuts or bones, with the sealed teeth for 24 hours post-treatment, to prevent dislodgement of the sealing material. Additionally, it is important to supervise the child's daily oral hygiene, ensuring they brush their teeth at least twice daily for no less than three minutes each time.
