Teeth may turn grey following trauma-induced pulp necrosis (death of the pulp). [2] This discoloration typically develops weeks or months after the injury and is caused by incorporation of pigments released during the breakdown of the pulpal tissue and blood into the dentin.
Occurs due to a localized and limited injury to the root surface or periodontium. It is a transient, self-limiting process of resorption that ceases after removal of the traumatic stimulus and is followed by healing of root surface, cementum, and periodontal ligament. [16]
Pulp necrosis is a clinical diagnostic category indicating the death of cells and tissues in the pulp chamber of a tooth with or without bacterial invasion. [1] It is often the result of many cases of dental trauma, caries and irreversible pulpitis.
Trauma is the most common cause of loss of permanent incisors in childhood. Dental trauma often leads to complications such as pulpal necrosis, and it is nearly impossible to predict the long-term prognosis of the injured tooth; the injury often results in long-term restorative problems.

grinding of teeth and a bad habit of chewing on things, such as pencils, pens, etc.; due to stresses caused by the seal. Expansion over time of the silver amalgam creates stress in the body of the dental unit. This process contributes to chipping and even deep longitudinal cracking, up to and including breaking the tooth in half.
Dental avulsion is a type of dental trauma, and the prevalence of dental trauma is estimated at 17.5% and varies with geographical area. [36] Although dental trauma is relatively low, dental avulsion is the fourth most prevalent type of dental trauma. [37] Dental avulsion is more prevalent in males than females.
After having patients describe in painful detail what caused their moral injury, therapists asked them to choose someone they saw as a compassionate moral authority and hold an imaginary conversation with that person, describing what happened and the shame they feel. They were then asked to verbalize the response, using their imagination.
The expansion of the field of regenerative endodontics was also dependent on the contributions from important studies in dental trauma. It has been proven that the vitality of dental pulp in immature teeth is preserved and it is free of signs and symptoms of disease even though it has sustained traumatic injuries such as avulsion and intrusion.
