My daughter broke off half of her front permanent tooth at 8. Is a crown the best option now at almost 16? (Photo)

She broke half her front permanent tooth off in the second grade at school. They tried a cap, but the tooth ended up needing a root canal within a few months of the trauma. She has had a resin filling over the tooth since then, but her teeth have grown and the tooth is much shorter than her others. She is nearly 16 and her pediatrician says she is finished growing, so we were thinking it would be a good time to get a crown done. Is this the best route? How long does the resin typically last?
