Baby teeth are just like adult teeth. They are vulnerable to plaque and tartar, and they can develop cavities and become infected, which can make your child uncomfortable and less likely to eat. Tooth decay, left untreated, can continue to progress, potentially leading to tooth loss.
It's important to keep in mind that, while baby teeth won't last forever, they play a vital role in how your child's permanent teeth will emerge. Baby teeth falling out prematurely can result in the surrounding teeth shifting into the gap. That can lead to crooked adult teeth or a crowded mouth, potentially requiring orthodontic treatment down the road.
Plaque and tartar left sitting on your child's teeth can cause bad breath and gum disease (periodontal disease), which is characterized by swollen, bleeding gums. The health of your child's smile matters, so don't forget to schedule a professional cleaning!
