What is a fossa and why do you need this on your child's teeth?

The fossa is on the teeth, whenever you look at your teeth in the mirror, no matter if it is the upper or lower teeth, there will be a small area where the teeth bite - the surface of the teeth, there will be a small area of uneven grooves, these grooves are the fossa.

The grinding of teeth at night is not normal, but its principle is similar to that of normal eating, and the grinding of teeth means chewing and digesting the food debris inside the teeth. These food residues are mainly hidden in the fossa, because the hiding place of food residues is the fossa concave place, it is not easy to notice and it is not easy to be cleaned up when brushing teeth. Over time, food debris can erode the teeth, which can lead to tooth decay.

The fossa closure is to use some synthetic material to fill the uneven surface of the teeth flat, the current dentist commonly used filling material is a polymer material, this polymer material is non-toxic, harmless, even if not sticky solid accidentally eaten on the filler's body is completely harmless. The polymer material coated in the fossa there, is equivalent to the teeth hit a protective sleeve.

The best time to close the fossa is when the child's teeth are all grown out, but then again caries has not yet begun to grow or just a little budding. In order to reduce the child's insect teeth, in fact, the child to do fossa sealing is also a good choice. After doing fossa sealing, parents should also let their children brush their teeth morning and night, and also remember to take their children to the dentist for regular checkups.

It is worth noting that not every child is suitable for fissure sealing, so parents should consider the following situations before considering whether or not to give their children fissure sealing operations. In general, deep sockets, especially those that can catch the probe, include suspected caries in pediatric patients. Secondly, all other teeth in the patient's mouth, especially those on the opposite side of the same name that have caries or are predisposed to caries, should be closed at this time.

For those children in the clinic, their teeth can reach a better occlusal plane after eruption. At this point, it is possible to try to close the fossa in conjunction with the actual situation of the pediatric organism. It is generally recommended that the operation be performed within 4 years after the eruption of the teeth. Many people may still have little knowledge about the operation of sealing, and it is generally believed that the best time for sealing in children is 3-4 years old for milk molars, 6-7 years old for first permanent molars, 11-13 years old for second permanent molars, and 9-13 years old for bicuspids. In addition, for those children with poor oral hygiene conditions, it is appropriate to consider relaxing the age of pediatric fissure sealing.
