What is serial extraction?
If your permanent front teeth do not have enough room to grow in properly, it is sometimes advisable to remove certain baby teeth in sequence. Removing baby teeth is like robbing Peter to pay Paul. Room is gained for the front permanent teeth by borrowing room from the teeth along the sides. Eventually the borrowed/loaned space must be repaid, by using orthodontic appliances to increase the space or by taking permanent teeth out.

Because carefully timed early extractions may prevent unfavorable positioning of permanent teeth and damage to the roots of adjacent teeth.
