Porcelain teeth may hurt your teeth when they are bonded on and then removed. Because porcelain teeth are bonded to the teeth with a cement, it is normal to cause some damage to the teeth when they are put on or taken off. However, the damage is usually not particularly severe and patients do not need to worry too much. When a porcelain tooth is bonded on and then removed, it needs to be separated from the real tooth. Generally, a deep groove is ground in the center of the porcelain tooth along the direction of tooth growth with a water drill lathe needle, and the whole porcelain tooth is ground from the buccal side to the lingual side. During the removal process, it is normal for the real teeth to be slightly damaged. If the damage is severe enough to cause gum damage or tooth sensitivity, treatment is required. However, patients do not need to worry too much, minor damage is normal, most of the care can be self-recovery. If serious pain, inflammation, tooth sensitivity occurs after the removal of porcelain teeth, it is recommended that patients go to the hospital in time for treatment.
