Eventually, teeth in the mouth are connected to the gum via ropes and when spacers are pushed away cause pain in the teeth. The braces spacers are kept for a period of one or max two weeks as they work quickly. Teeth are not able to bear the extra pressure and surrenders to the spacers. After the spacers are removed, you need to put braces on it to relieve pain or irritation.
If the space is not preserved, the other teeth may drift causing difficult to treat crowding and orthodontic problems. If it is a front tooth then you don't need a space maintainer. However, you can place a Pediatric Partial to replace the teeth for cosmetic reasons. Now Spacers may be in there for a while, but they are not permanent. They are removed when the new tooth (usually a bicuspid) erupts or the abutment teeth get loose.
