dental check up in school

Today, the little bratinella went home from school with a letter from their dentist. Apparently, it was the pre-school department's dental week and each of the students were checked for any possible teeth problems. And since she's been eating sweets lately and start losing her milk teeth, her dentist's recommendation : her right side of teeth upper (E D C B A), needs filling (amalgam or light cure) asap. Very bad! and really need to act on this one fast! I don't want the little girl to have teeth problems in the future. Or even worse, if the problem persists, might be needing major dental implants. Though I heard dental implants Mexico offers a good package and service, not sure if I can afford it at this time with the new baby addition in our family.
