Usually you can go on eating after the fissure closure without any effect on your diet. This is because the material of the fossa seal itself is a photocoagulable curing material that is fluid until it is irradiated by a special light, but after it is irradiated it becomes very hard and does not come off easily, so it does not interfere with eating. The material for fissure sealing is coated on an area that basically receives no biting force, so even if you eat, the area is basically free of force, so you can safely and boldly proceed to eat after the sealing is done. However, it is important to note that you will not be able to eat on the affected side until the treatment is completely finished. Therefore, if you are not sure about the treatment, please consult your doctor after the treatment is completed and follow the doctor’s instructions.
