Usually dental trauma causes no harm because teeth are resilient that it can readily recover with sufficient healing time. However, if the trauma causes severe injury to the tooth that it affects the nerve within the tooth, the nerve will slowly die and the nerve is said to be necrotic. The tooth won’t get the nutrient it needs. Overly, the tooth will become darker in color because the deaden nerve causes intrinsic changes to the internal tooth structure and as the result, the tooth would lose its original luster.
This type of changes in tooth color is called intrinsic staining. Simply external bleaching the tooth is not effective in alleviating the problem. The deadened tooth needs root canal therapy and then dentist can use the internal bleaching technique to change the tooth color from the inside. This internal bleaching could improve the appearance of the tooth. However, for a more complete masking of the darkened color, dentist could put on a dental porcelain crown.
