Extraction of the wrong tooth: Misdiagnosis, altered tooth morphology, faulty clinical examination, poor patient history, undetected/unmentioned previous extractions that may predispose the operator to consider another tooth to be a replicate of the one previously extracted are a few causes of extraction of a wrong tooth.
Because impacted teeth do not erupt, they are retained throughout the individual's lifetime unless extracted or exposed surgically. Teeth may become impacted because of adjacent teeth, dense overlying bone, excessive soft tissue or a genetic abnormality. Most often, the cause of impaction is inadequate arch length and space in which to erupt.
If unfavorable healing has occurred, the tooth can last into the medium term for 2-10+ years [30] depending on the speed of bone turnover. [34] [31] Long-term survival of the tooth only happens when favorable healing of the periodontal ligament has occurred. If this happens the tooth can be estimated to survive as long as any other tooth [33]
The management depends on the type of injury involved and whether it is a baby or an adult tooth. If teeth are completely knocked out baby front teeth should not be replaced. The area should be cleaned gently and the child brought to see a dentist. Adult front teeth (which usually erupt at around six years of age) can be replaced immediately if ...
Once a trauma has occurred dilaceration can be prevented by yearly visits to the dentist and maintaining radiographic images to note any changes that may occur. If changes do occur, treatment can be done through orthodontic treatment or the tooth may be completely extracted by a dentist to prevent impaction on permanent teeth. [10]
Secondary (permanent) teeth can be replaced and stabilised by a dentist. [23] Primary (baby) teeth are not replaced because they tend to become infected and interfere with the growth of the secondary teeth. [23] A completely avulsed tooth that is replaced within one hour of the injury can be permanently retained. [23]
