Most parents are all too familiar with the sight of their child zooming around the house, toothbrush still in hand, or sipping from a reusable straw while playing. While it may seem like harmless fun, these everyday objects can pose serious risks when used improperly.
At Mission Bay Pediatric Dentistry, Dr. Erin Shah and her team often speak with families about common household habits that can lead to injuries, and toothbrush and straw accidents are among them. By understanding the risks and learning simple prevention strategies, parents can keep oral care and nutrition routines both safe and stress-free.
Why Running with a Toothbrush or Straw Can Be Dangerous
Although toothbrushes and reusable straws are essential tools for healthy routines, they're not designed for active movement. When children run, jump, or fall with these items in their mouths, there's a risk of serious injury, especially to the soft tissues in the mouth and throat.
In rare but grave situations, a sudden impact could even result in deep tissue damage or trigger severe medical emergencies such as internal bleeding or vascular trauma. Potential dangers include:
- Lacerations or punctures to the gums, cheeks, tongue, or throat.
- Disruption of soft palate structures, which could impact swallowing or speech.
- Serious medical emergencies like an aneurysm or torn artery that may lead to stroke or airway obstruction. This risk is higher for children because their oral anatomy is closer to major vessels.
Dr. Erin Shah, a board-certified pediatric dentist with extensive training in complex pediatric care, often educates families about these lesser-known risks. Her comfort-focused practice is designed to help kids feel secure, and this includes guiding them toward safe dental hygiene habits at home.
Safe Brushing Techniques for Kids
Setting your child up for safe and effective brushing starts with age-appropriate tools and techniques. Encouraging brushing in a calm, still environment, rather than while multitasking or moving, can significantly reduce the risk of injury.
Make brushing part of a predictable and safe routine. Consider these safety tips during brushing time:
- Use child-sized toothbrushes with soft, rounded bristles.
- For littles under 3 or so who might be extra wiggly, having your child lay between your legs on the bed or couch can give you the visibility you need to both be safe and do a high-quality job. This position also allows you to support the head better against sudden movements and allows you to retract the cheek and lips for better visibility and cleaning.
- For school-aged children getting help from a parent (which should be night-time brushing for any kid under 9 years old!), having your child recline back on your lap, while you sit on the bed couch or floor.
- For older kids brushing on their own, brushing preferably at the bathroom sink or another designated spot free of distractions or hazards.
- AVOID trying to brush your child’s teeth while they are standing or sitting on the bathroom counter. This leaves the child’s head inadequately supported, and sudden movements or even a fall, could easily cause injury.
In our cozy, child-friendly dental office, we help parents and kids learn safe and effective brushing and flossing techniques. From silly sunglasses to engaging goodie bags, our kid-approved environment keeps kids excited about oral health while building safe brushing habits they can carry home.
What to Do If a Toothbrush or Straw Injury Occurs
Accidents can happen in seconds, even when you're being cautious. If your child suffers an injury with a toothbrush or straw, it’s important to act quickly and calmly. Depending on the severity, you may be able to manage minor cases at home, but more serious injuries require prompt medical or dental attention. Follow these steps based on the nature of the injury:
- Minor cuts or scrapes: Rinse your child’s mouth with water and apply a clean, damp cloth to stop any bleeding.
- Persistent bleeding or pain in the gum or lip area: Apply gentle pressure and contact your pediatric dentist or family physician.
- Deep punctures, gash or signs of bruising near the throat, roof of the mouth, back of the throat or area behind the teeth, breathing difficulty, or signs of shock: Seek emergency medical care immediately.
Dr. Shah and the team at Mission Bay Pediatric Dentistry are here to guide you through post-injury care. If you’re ever uncertain about the seriousness of an oral injury, it's always wise to call our office at (415) 825-3323 to determine next steps.
Prevention Tips Every Parent Should Know
Childhood comes with its fair share of bumps and tumbles, but many oral injuries involving toothbrushes or straws are entirely preventable with a little foresight. Creating safer routines and reducing distractions during brushing or drinking can go a long way. Try incorporating these simple prevention strategies into your child’s day:
- Designate “no running with objects” areas in your home, especially around the bathroom and kitchen.
- Switch to flexible silicone straws instead of rigid plastic or metal ones whenever possible
- Limit straw usage to seated activities like meal or snack time.
- Gently remind your child to take their toothbrush out of their mouth if they walk away from the sink.
- Use stable positioning for helping your child with toothbrushing and avoid situations where your child could become off-balance or fall with a toothbrush or other in their mouth.
