We only have one chance of changing our set of teeth from milk to permanent. When we get our permanent set of teeth, everything else we put inside our mouth like food and drinks, will affect our teeth throughout the remaining days, months and decades of our lives. If we cannot take care of our teeth or our children’s teeth well enough, it is more probable that we need to see a dentist several times in our (or their) lives.

Candies cannot be avoided unless you really are not into it. It is not actually the candy that does the ruining of the teeth but the length of stay of the sweet around the teeth due to prolonged delay in brushing our teeth. If that becomes a habit then teeth are bound to call for a dentist.
Dentists or Denture clinics are not expensive. Good thing there is such a thing as dental plan like Ameriplan which is a program that makes our payment easy and our teeth fully taken care of. That way regular checkup, cleaning and everything else can be done as necessary without the fear of having to spend out of the budget for something else. As the saying goes, if you fail to plan, you plan to fail.
