One common reason for tooth extraction is when a baby tooth has abnormal roots, preventing it from naturally falling out. In such cases, removing the baby tooth becomes necessary to pave the way for the eruption of a permanent tooth. Additionally, advanced decay in a tooth can pose a threat to neighboring teeth, making extraction and replacement with a bridge or implant a viable solution.

Infections, orthodontic issues or problems with wisdom teeth are other common factors that may necessitate tooth removal. Infected teeth can not only cause pain but can also lead to more severe health problems if left untreated. Orthodontic corrections sometimes require the removal of overcrowded or misaligned teeth to create space and achieve proper alignment. Wisdom teeth, often causing discomfort and complications due to their late eruption, frequently require extraction to prevent oral health problems
