Dental Common Access System Is It Common That My 6 Year Old Daughter Will Need Major Dental Work?

Is it common that my 6 year old daughter will need major dental work? - dental common access system

I have them in the dentist for the 1st Viewed today, and I knew what our Pratices teeth are not perfect. But the dentist said that he had cavities so they need to "save as" to employment, especially for your comfort. Is this normal? I am also afraid, deprived of professionals and experts who can do everything that they do.
