What you are talking about is a common method to solve the imbalance of anterior teeth in orthodontics, which is called extraction of adjacent teeth. Usually, before doing it, you should explain it clearly to the patient and ask his permission before doing it. You should not bully others. Usually, four mandibular incisors are polished to change them from inverted triangle to rectangle, which can leave a gap to align the incisors and solve the problem that the Bolton index of the upper and lower incisors is not adjusted, and the gap will be closed after the teeth are aligned. The biggest complication is that the grinding area is rough in a short time, which is easy to cause plaque and tartar accumulation, thus leading to dental caries. Therefore, after the adjacent surfaces are glazed, we should pay attention to oral hygiene and brush our teeth carefully, especially the glazed parts, so as to avoid dental caries.
So don't be too afraid, just pay attention to oral hygiene.
