In this brief video, Dr. Katie To warns parents that mouth breathing in children is not a harmless habit. She explains that chronic mouth breathing can alter jaw and facial development, impair sleep quality, reduce focus, and later lead to crowded teeth and other preventable health issues. Emphasizing that a child's oral structures are still developing, she advocates for early detection and intervention—such as addressing snoring, mouth breathing, or dental crowding—to redirect the child's health trajectory. The video ends with a direct call to action, urging viewers to tag other parents who need to see the message.

If your child sleeps with their mouth open, stop scrolling. I know it looks cute. I know it seems harmless. But mouth breathing in children is not normal, and most parents don't find out until it's already caused problems. When a child breathes through their mouth instead of their nose, their jaw develop differently, their face grow differently, their sleep suffers, their focus suffers, and by the time they are teenager, we're looking at crowded teeth, sleep issues, and problems that could have been prevented. Here's what I want you to know. Your child's mouth is developing right now. How they breathe, how they chew, how their jaw grows. It all matters. Early intervention can change the entire trajectory of their health, not just their teeth, their whole life. If your child snores, breathe through their mouth, or have crowded teeth, don't wait. Tag a parent who needs to see this.
