My ten year old son hit his mouth on a metal apparatus at a park. He chipped one permanent front tooth and horizontally broke the other front tooth and the one next to it leaving the root on both. Recommendation was to bond chipped tooth and have a root canal and crown for the two broken teeth. I am concerned that this procedure isn't the proper one for him considering he is ten and is still growing. I fear that there will be spacing later due to growth. What do you suggest?
