Yellow Teeth

Why Do Kids Have Yellow Teeth? It can be surprising for parents to notice their child’s teeth looking yellow. While we often expect bright white smiles, it’s important to know that yellow teeth in children are fairly common—and not always a cause for concern. One of the most common reasons is the natural color difference between baby and adult teeth. Permanent teeth are usually larger and have a thicker layer of dentin beneath the enamel, giving them a slightly more yellow appearance compared to baby teeth. This is especially noticeable when new adult teeth erupt next to whiter baby teeth. Plaque buildup and staining are also factors. Inadequate brushing and flossing can leave behind plaque that hardens into tartar, which looks yellow. Drinks like soda or juice, and even certain foods, can cause staining over time. Other causes include weak enamel, the use of some antibiotics in early childhood, or too much fluoride exposure (fluorosis). In rare cases, yellow teeth may indicate developmental issues with enamel. The good news is that most cases are manageable. Encouraging twice-daily brushing with a fluoride toothpaste, regular flossing, and dental checkups can help keep your child’s smile healthy. Professional cleanings also remove stains that at-home brushing can’t. If you’re worried about the shade of your child’s teeth, your dentist can determine whether it’s a natural variation or something that needs treatment. Remember, healthy teeth come in many shades—and what matters most is keeping them strong and cavity-free.
