Lip Biting and Mouth Sores: Understanding Why Kids Do It and How to Help

As a parent, noticing your child biting their lips or developing small mouth sores can be concerning. Luckily, kids dentistry experts in Paradise Valley, AZ are here to guide parents on understanding why this happens and how to manage it effectively.

Why Do Kids Bite Their Lips?

Lip biting is surprisingly common among children and can happen for several reasons:

Nervous Habits or Anxiety – Some kids bite their lips when they’re stressed, anxious, or even bored. It’s similar to nail-biting and often happens subconsciously.

Teething or Dental Changes – As children grow and their teeth shift, the lips may feel more sensitive, prompting occasional biting.

Oral Sensory Needs – Some children bite their lips to explore sensations in their mouth. This is especially common in younger kids.

Understanding the root cause helps parents respond calmly rather than punishing the habit.

Common Mouth Sores in Kids

Mouth sores can appear for various reasons, from minor injuries to viral infections. The most common include:

Canker Sores – Small, painful ulcers inside the mouth that are not contagious.

Cold Sores (Herpes Simplex) – Blisters that typically appear on the lips and are contagious.

Irritation from Lip Biting – Repeated biting can cause red, sore areas on the lips or inside the mouth.

Recognizing the difference between these conditions is key. If you’re unsure, a visit to a kids dentistry professional in Paradise Valley, AZ can provide peace of mind and proper care.

How to Help Your Child

Here are some effective strategies parents can use:

Positive Reinforcement – Praise your child when they avoid lip biting instead of scolding them.

Provide Alternatives – Offer sugar-free gum or chewy toys to satisfy oral sensory needs.

Maintain Oral Hygiene – Clean the lips and mouth gently, especially if sores appear, to prevent infection.

Use Protective Balms – A child-safe lip balm can reduce dryness and irritation that triggers biting.

Address Underlying Stress – If lip biting is anxiety-related, gentle conversations or relaxation techniques can help.

When to See a Professional

If sores are persistent, unusually painful, or your child develops fever or swelling, it’s important to consult a kids dentistry specialist in Paradise Valley, AZ. Early evaluation ensures proper treatment and prevents complications.

Bottom Line:

Lip biting and common mouth sores are frequent in children, but with awareness and simple strategies, parents can help their kids maintain healthy, happy smiles. Paying attention to habits and oral hygiene is key to preventing pain and promoting confidence in your child’s smile.
