Preventive dental care is important for children, pregnant women, and older adults. Despite their busy schedules, children should visit a dentist every six months for a cleaning and checkup. Tooth decay can lead to other health issues such as a broken jaw or even sepsis. Therefore, it's important for you to eat a balanced diet with plenty of vitamins and minerals to nourish your child's growing teeth. A dental checkup is also necessary, as you may already have some gum disease or cavities.
