Thumb-sucking. Pacifiers. Snoring.
If you’re a parent, you’ve probably dealt with at least one of the “big three” (if not all of them).
These habits may be incredibly common in early childhood. However, are they really a harmless phase or are they a cause for concern — how long is it really before these habits start affecting your child’s growth, sleep, and long-term oral health?
During Children’s Dental Health Month, Drs. Elizabeth and Jeff Eggert want parents to feel empowered when it comes to supporting children’s oral development. That means understanding what’s typical, what’s not, and which signs may be worth a closer look.

Let’s break it down together.
The Big Picture
When most people think of children’s dental care, they think of candy-induced cavities and teething pains. But the truth is, children’s oral development is about much more than teeth.
Your child’s mouth, jaw, tongue, airway, and facial muscles all work together to support things like:
- Healthy breathing through the NOSE
- Clear speech development
- Proper swallowing patterns
- Balanced facial and oral growth
- Comfortable and restful sleep
- Strong, aligned teeth and jaws
These early years are a major growth window. That’s why childhood habits like thumb-sucking, pacifier use, or chronic mouth breathing influence not just your child’s smile, but their overall development too.
Pacifiers and Thumb-Sucking: When to Start Paying Attention

If your baby uses a pacifier or sucks their thumb, take a deep breath. Many people find comfort in being able to soothe their children.
These habits can be soothing and developmentally normal in the earliest of childhood development. And, many babies naturally outgrow the need to use these interventions without any stress.
That said, the timing does matter. At some point, thumb-sucking and pacifiers do become cause for concern. Generally, concerns increase when:
- The habit continues as teeth begin coming in
- The habit becomes very frequent or intense
Some children may keep sucking habits longer than expected, especially during stressful transitions (new sibling, starting preschool, changes in routine). If that’s the case in your home, you’re not alone. It may simply be a sign that your child needs a little extra support and a gentle, consistent plan.
Drs. Elizabeth and Jeff Eggert often remind families it’s not about shame or pressure — it’s about guiding development at the right time and starting as early as possible to help the child break the habit.
The Long-Term Impact of Prolonged Sucking Habits
Thumb-sucking and pacifier use don’t automatically cause problems, but when they last too long or happen too often, they influence how the mouth grows.
Some possible changes include:
- Open bite (front teeth don’t touch when biting down)
- Protruding front teeth
- Narrower palate (roof of the mouth)
- Crowded teeth
- Changes in jaw growth patterns
These changes can affect more than appearance. They may impact chewing, speech development, cognitive development, and how easily teeth stay clean.
The earlier these issues are noticed, the easier it can be to support healthier growth patterns with simple, proactive guidance.

Snoring, Mouth Breathing, and Children’s Oral Development

This is a big one, and it’s often overlooked.
Many parents assume snoring is “just cute,” especially if their child seems otherwise healthy or if their pediatrician doesn’t say anything. But in pediatric dentistry, snoring is a HUGE red flag into letting us know that developmental issues are occurring.
Why Snoring Deserves a Closer Look
Oxygen is essential for every system in the body. Your child’s brain, immune system, growth, and mood all depend on steady, high-quality breathing — especially at night when their body and brain are doing so much of their development and repair.
Snoring is a sign that your child’s airflow is partially blocked. That can lead to lighter, more disrupted sleep, even if your child stays in bed all night. Over time, poor sleep quality can show up as daytime symptoms that don’t seem connected at first, such as fatigue, irritability, trouble focusing, or hyperactive behavior.
Mouth Breathing Changes How the Mouth Grows
When kids cannot breathe comfortably through their nose, their bodies will adapt to get enough air. This manifests as mouth breathing.
Mouth breathing matters because it affects more than airflow. It changes the way the tongue, lips, and jaw rest throughout the day and night. The tongue is designed to rest gently against the roof of the mouth, where it supports healthy palate development and guides both how the jaws grow as well as how the nasal airway grows. When the tongue rests low instead, the palate develops higher and narrower and the jaws grow with less space for teeth and proper alignment.
Over time, mouth breathing contributes to:
- A narrow palate and crowded teeth
- Bite issues (such as open bites or crossbites)
- A longer, more vertical facial growth pattern
- Dry mouth (which increases plaque buildup and cavity risk)
- Gum irritation and inflammation
- More plaque buildup due to reduced saliva protection
Understanding Orofacial Myofunctional Disorders
Orofacial myofunctional disorders (OMDs) involve how the tongue, lips, and facial muscles function at rest and during swallowing and speech. These patterns often develop alongside chronic mouth breathing and can impact everything from speech clarity to bite development.
Eggert Family Dentistry in North Oaks, Minnesota explains this in more detail here: Orofacial Myofunctional Disorder and Its Effect on Breathing
Airway Issues Affect More Than Sleep
When breathing is disrupted at night, parents may notice signs like:
- Daytime fatigue (even after a full night in bed)
- Difficulty focusing or brain fog
- Behavioral changes or irritability, including signs and symptoms of ADHD
- Bedwetting
- Teeth grinding
This is why Dr. Elizabeth Eggert and Dr. Jeff Eggert encourage parents to take snoring seriously. It influences children’s oral development, sleep quality, and overall health as they grow.

Simple Steps Parents Can Take at Home
You don’t need to panic, or do everything at once. Small steps make a big difference, especially when they’re consistent.
Helping Kids Move Away From Thumb-Sucking and Pacifiers

If your child is still thumb-sucking or relying heavily on a pacifier past the age of 6 months to one year, a gentle, supportive approach is often the most effective. Kids tend to use these habits for comfort; with the right plan, they can transition away from them without stress.
The first step is to simply spot the pattern. Pay attention to when your child typically starts reaching for that thumb or pacifier. It’s often during bedtime, screen time, car rides, or stressful moments.
Once you know what triggers it, you can respond more intentionally instead of feeling like you’re constantly correcting it. Try supportive strategies like:
- Praise progress, not perfection
- Offer comfort replacements (stuffed animal, blanket, sensory toy)
- Use a simple reward chart for “thumb-free” time
- Create a bedtime routine that reduces anxiety
Avoid punishment or shaming. It should feel like you and your child versus the thumb or pacifier — not you versus your child. Many kids don’t even realize they’re doing it, much less that it’s a problem.To your child, it feels good, they don’t understand the implications of altered growth.
Encouraging Nasal Breathing and Better Sleep
Breathing through the nose and keeping the tongue in a healthy resting position play a bigger role in children’s oral development than most parents realize.
If you want to encourage better habits at home, start with small, realistic changes:
- Have your child use saline nasal spray daily to keep the nasal airway clear and open
- Address allergies with your pediatrician if needed
- Use gentle “lips together and breathe through your nose” reminders
- Encourage side sleeping so your child’s tongue doesn’t block their airway
- Use a humidifier to reduce nighttime congestion
- If other options aren’t working, use Myobrace Therapy with Dr. Elizabeth Eggert [link to myobrace blog and this month’s patient of the month blog]
These small habits can support better sleep, healthier facial growth, and a more balanced bite.
When It’s Time to Ask a Professional

Some habits simply fade with time. Others can quietly shape how your child’s mouth, jaw, and airway develop. Well before these become long-lasting habits with emerging side effects, it is worth scheduling an evaluation with Eggert Family Dentistry so you can catch concerns early and get guidance that’s specific to your child.
Consider scheduling an evaluation if you notice:
- Frequent snoring
- Mouth breathing during the day or night
- A pacifier or thumb-sucking habit that isn’t improving with time
- Bite changes (open bite, teeth shifting forward)
- Speech concerns
- Tongue thrusting
Even if everything turns out to be normal, having Dr. Elizabeth Eggert or Dr. Jeff Eggert take a look can give you clarity and peace of mind. Sometimes the best next step is simply getting answers and reassurance
