If the bite is incorrect because of the newly restored denture, the patient will feel more comfortable if the bite is adjusted to normal by the treating doctor. If the patient has a toothache or feels that one side is high and the other side is low for their natural teeth, they need to be diagnosed promptly. It is likely that the high side of the tooth is inflamed, causing the tooth to float upward. If the inflammation is clear, root canal treatment can be performed on the affected tooth in time. After the root canal treatment, the periapical inflammation disappears, the floating feeling of the tooth will improve or even disappear completely, and during the treatment, the doctor will also adjust the bite for the patient to reduce the biting pain.
