Generally speaking, minors under 18 are not encouraged to do all-ceramic tooth restoration, because the pulp cavity of minors under 18 is immature, and it is necessary to grind the original tooth a layer before making all-ceramic teeth. If the teeth are not fully developed at this time and the pulp cavity is wide, it is easy to hurt the pulp. Once it is done, secondary repair is likely to occur.
In addition, all-ceramic tooth restoration will also involve the root. If you are too old, it is likely to be affected by gingival atrophy, loose teeth, general condition and psychological factors.
