1, tooth decay will destroy the anatomical shape of teeth, affect the appearance of front teeth, and reduce the chewing efficiency, which may cause indigestion.
2. When the cavity reaches the dentin, it will be painful to be stimulated by cold, heat, acid and sweetness, which will interfere with chewing and eating.
3, the caries formed on the adjacent surface of the crown is easy to be embedded in food residue, which stimulates the swelling of the gingival papilla and sometimes forms an abscess.
4. When dental caries reach the pulp and cause acute pulpitis or periapical periodontitis, it can cause severe pain and even affect sleep.
