What about 5 year old toothache?

An oral examination is required. The first permanent molar is erupting, and the gums covered by the crown surface are inflamed. 3% hydrogen peroxide solution can be used to rinse, and iodine can be applied to promote inflammation. Second, the adjacent relationship of deciduous teeth is poor, causing food fiber to be impinged, causing gingival papilla inflamed. 3. when x-ray shows that deciduous teeth form deep caries, a spoon can be used to remove large pieces of decay, prepare a hole shape, place zinc polycarboxylate cement at the bottom of the hole, and fill it with glass ion cement.4. if pulpitis occurs in deciduous teeth, infected pulp can be removed under local anesthesia, rinsed and disinfected, and calcium hydroxide paste can be used to seal root canals and repair crowns.
