The treatment of gaps in fillings usually involves the use of molding sheets and wedges to assist in restoring the normal form of the tooth, leaving a gap between the two teeth.
Fillings that involve the adjacent surfaces of the teeth often require the use of other instruments such as molding sheets and wedges to restore the normal form between the two teeth, which can ensure that the adjacent surfaces of the teeth are filled in a form that is smooth and close to the natural tooth, while at the same time allowing the floss to pass through. The decayed portion of the adjacent surface is usually removed by grinding with specialized instruments, then cleaned, bonded and shaped using bonding agents and resins, and finally light cured and polished to the gap.
The most important thing about filling the gap is to restore the tooth abduction gap, and it is recommended to go to a professional dental hospital for treatment.
