5 Common Dental Problems in Kids and How to Avoid Them

April 13, 2025

While it’s easy to focus on brushing and flossing, many children still face common dental issues that can affect their comfort, confidence, and overall well-being. The good news is most of these issues are completely preventable. Continue reading to learn about five of the most common dental problems in children.

  1. Tooth Decay (Cavities)

Tooth decay is the most prevalent chronic disease in children. If left untreated, cavities can cause pain, infection, and difficulty eating or speaking. This problem is especially common in young children due to frequent snacking, sugary beverages like juice or soda, and inconsistent brushing routines.

How to avoid it:

  • Encourage brushing twice a day with fluoride toothpaste.

  • Help younger kids brush to ensure they reach all tooth surfaces.

  • Limit sugary foods and drinks, especially sticky snacks that cling to teeth.

  • Introduce healthy snacks like fresh fruits, vegetables, and cheese.

  • Schedule regular dental checkups and professional cleanings.

  • Ask your pediatric dentist about fluoride treatments or dental sealants for added cavity protection.

Preventing cavities early on is one of the most important steps in managing your kids dental problems and treatments over time.

  1. Gum Disease (Gingivitis)

Gingivitis is another common condition in children, though it’s often less advanced than in adults. Signs of gingivitis in kids include red, swollen, or bleeding gums, especially when brushing or flossing.

How to avoid it:

  • Teach children to brush gently along the gum line with a soft-bristled toothbrush.

  • Introduce flossing as soon as two teeth touch.

  • Make brushing and flossing a consistent part of the daily routine.

  • Visit the dentist regularly for cleanings to remove plaque and tartar buildup.

Addressing gum disease early is key to avoiding more complex kids dental problems and treatments in the future, such as periodontal disease.

  1. Tooth Sensitivity

Tooth sensitivity can cause discomfort or pain when your child eats something hot, cold, sweet, or sour. While this issue is often temporary, it may indicate underlying problems like enamel erosion, cavities, or even new permanent teeth erupting.

Kids may not always verbalize sensitivity, but they might avoid certain foods or flinch when brushing.

How to avoid it:

  • Use toothpaste designed for sensitive teeth, under your dentist's recommendation.

  • Avoid overly acidic foods and drinks, like citrus fruits or soda.

  • Use a soft-bristled toothbrush and teach gentle brushing techniques.

  • If your child complains of sensitivity, schedule a dental appointment to rule out cavities or other concerns.

Tooth sensitivity is one of those kids dental problems and treatments that may seem minor but can also point to bigger issues.

  1. Teeth Grinding (Bruxism)

Teeth grinding or clenching, known as bruxism, is surprisingly common among children. It can be caused by stress, misaligned teeth, or even certain medical conditions. Over time, grinding can wear down enamel, cause headaches, or lead to jaw pain. You might notice your child grinding their teeth at night, or a dentist might identify worn tooth surfaces during a routine exam.

How to avoid it:

  • Monitor your child for signs like jaw soreness, morning headaches, or unexplained tooth wear.

  • Reduce stress with calming bedtime routines or relaxation techniques.

  • If needed, ask your pediatric dentist about a custom mouthguard to wear at night.

  • Address any bite issues or alignment problems early through an orthodontic evaluation.

Proper treatment for teeth grinding can prevent long-term damage and is a vital part of managing kids dental problems and treatments.

  1. Orthodontic Issues

Many children experience orthodontic issues such as crooked teeth, crowding, or bite misalignment. While genetics often play a role, habits like thumb-sucking, extended pacifier use, or early loss of baby teeth can contribute as well. 

How to avoid it:

  • Discourage thumb-sucking and pacifier use after age 3.

  • Ensure your child visits a dentist regularly to monitor the eruption of permanent teeth.

  • Follow your dentist’s recommendation for early orthodontic evaluations, typically around age 7.

  • Address problems early to reduce the need for more invasive treatment later on.

Preventing or treating orthodontic issues early on can significantly reduce the common dental problems in children.

Healthy habits and regular dental visits go a long way in preventing most common dental issues in children. From cavities and gum disease to teeth grinding and misalignment, staying informed allows you to take proactive steps to protect your child’s oral health.
