When do I need to do the vomerontal treatment? Since permanent teeth erupt at different times, it takes several sessions to complete. The focus is on the early eruption of the molars and the need for fissure closure. Sixth-aged teeth are the first teeth to be closed, followed by the second molars (which erupt around age 12) and finally the bicuspids (which erupt around age 13). The first year after the eruption of the permanent teeth is the most susceptible to caries. As long as the teeth are not yet decayed, the treatment of sulcus closure is necessary. How easy is it to perform the treatment? The operation of the treatment is simple, painless and without anesthesia. The operation is done in two steps: 1. Clean and keep the tooth dry. Before the operation, all bacteria and food residues are removed from the tooth surface, otherwise the sealant will come off easily. After the teeth are cleaned and treated with acid etching, cotton rolls are placed around the teeth to ensure that they are dry. 2.Apply the sealant to the tooth surface and cure it. The sealer is a liquid flowable resin that is placed on the occlusal surface of the tooth and can be fully filled in the tooth sockets. A special light-curing lamp cures the sealer well in the tooth sockets, forming a protective film.
