Common Pediatric Dental Issues and How to Prevent Them

From that first baby tooth to the teenage years, your child’s smile is constantly changing—and so are the dental concerns that can pop up along the way. At Dentistry 4 Children in Southlake, Dr. Rohini Bajaj is here to help you understand the most common pediatric dental issues—and how to stay one step ahead with prevention, healthy habits, and regular checkups.

1. Tooth Decay (Cavities)

Tooth decay is one of the most common chronic conditions in children—and it can start earlier than many parents expect. Cavities can form when sugars from food and drinks feed harmful bacteria in the mouth, leading to acid that wears down enamel.

• Brush twice daily with a fluoride toothpaste to strengthen enamel and remove bacteria.
• Begin flossing when two teeth touch to clean between tight spaces.
• Limit sugary snacks and drinks—especially juice, gummies, and sticky snacks.
• See Dr. Bajaj for regular checkups starting by age 1. Professional cleanings and fluoride treatments can offer added protection.

2. Early Loss of Baby Teeth

Baby teeth serve more than a temporary purpose—they help guide permanent teeth into position. If baby teeth fall out too soon due to decay or injury, it can lead to spacing issues or crowding.

• Keep baby teeth healthy with consistent brushing, flossing, and cleanings.
• Use mouthguards during sports or physical play to protect against injury.
• If a tooth is lost too early, Dr. Bajaj may recommend a space maintainer to preserve alignment until the adult tooth is ready.

3. Thumb Sucking or Pacifier Use Beyond Age 3

These habits are perfectly normal in infancy, but if they continue past age 3–4, they can begin to affect the shape of the jaw or how teeth line up. Prolonged sucking pressure may cause open bites, overbites, or speech issues.

• Begin gently discouraging thumb sucking or pacifier use around age 2–3.
• Offer comfort items or praise for going without.
• Need support? Dr. Bajaj can help with personalized advice or appliance options if habits are hard to break.

4. Dental Injuries (Chips, Cracks, Knocked-Out Teeth)

From playground falls to unexpected tumbles, dental injuries are a common concern. Even baby teeth can cause pain or infection if damaged, and permanent teeth need immediate care if knocked out.

• Always wear a mouthguard during sports and high-energy activities.
• Supervise play in toddler years and childproof sharp furniture corners.
• In case of a dental emergency, contact our office immediately—quick treatment makes all the difference.

5. Orthodontic Concerns: Overcrowding, Bite Issues

Even before all permanent teeth come in, early signs of orthodontic issues may appear. Crooked, crowded, or protruding teeth can make it harder to brush properly, increase the risk of decay, and impact speech or self-esteem.

• Dr. Bajaj monitors your child’s growth and bite alignment at every checkup.
• We recommend an orthodontic screening around age 7—even if things look fine on the surface. Early intervention can reduce the need for more complex treatment later.
