[/INST] Hello & welcome, Protruded teeth are more to get traumatized or broken as compared to normally aligned teeth specially in children. But as you had an accident leading to breakage of the front teeth, Root canal treatment followed by placement of three unit bridge was correct decision. If natural teeth were protruded, then while making bridge this alignment can slightly be improved by adjusting the placement of the bridge. But this carries physiological limits with it. If the bridge is in the place properly, then never think that it will let the underneath teeth to protrude more than present. This is because bridge itself is an obstruction for teeth movement. But still movement can occur only if the abutment teeth are peridontically weak or patient presents with poor oral hygiene. Keep your cleaning habits proper. Visit your dentist regularly for clinical examination so that any slight movement can be anticipated & treated immediately. Take care. </s>
