Dental mineralization can be seen in the teeth by long-term wear and other external stimuli caused by the pulp cavity mineralization, generally need to remove the bad external stimuli, adjust the bite to prevent excessive wear and tear of the teeth. When the tooth is subjected to long-term external stimuli, night grinding or bad biting habits, long-term wear of the tooth is likely to lead to thickening of the wall of the pulp chamber, or the appearance of pulpite in the root canal, usually X-ray film can be observed in the wall of the pulp chamber thickening. It is necessary to remove external stimuli, make jaw pads to wear for nocturnal grinders, adjust the occlusion if there is an occlusal high point, and consider making crowns to protect the teeth if they are overly worn out. Mineralization in the pulp chamber of the tooth can block the root canal and cause poor root canal treatment later, so it is recommended to deal with the problem as soon as possible after detection.
