Yes and no. Cavities themselves are not likely to impact the permanent teeth when they grow in, but the behavior that caused the decay in the first place can result in more problems.

In other words, if you don’t address whatever habits contributed to the cavity, your child’s permanent teeth will be at greater risk for decay once they come in. So talk to your dentist about what might be at the root of the dental decay, and take steps to change any risky behavior.

For example, children who frequently snack and drink sweetened beverages (including fruit juice) between meals are at a higher risk for decay than those who primarily eat only at mealtimes and drink water between meals.

In addition, some decay-inducing oral bacteria can be transferred to your child by sharing a cup or spoon. So minimize the saliva swap -- and maintain your own oral health -- and you’ll help safeguard your kids’ smiles as the years go by.
