Each of us has our own level of risk for tooth decay. Some of us are more likely to get cavities, while others seem more resistant. For this reason, some children will seem to get cavities time and again, while other children, even if they have poorer hygiene or eat more sweets, will "slide by" without problems.

Differences in risk relate to a number of factors. These include:

• The number of decay-causing bacteria in your child's mouth
• How often your child snacks between meals
• What your child eats
• Your child's access to fluoride (through drinking water, toothpaste, etc.)
• How well your child cleans his teeth

Because your son is more cavity-prone than some other children, you and he will need to work together to keep more cavities from forming. Talk to your dentist about carefully managing diet, hygiene, and use of fluorides. You also can talk with your dentist about sealants, plastic coverings for your child's permanent molars.
