Digit Sucking / Pacifier Use

Sucking is quite normal in babies and young children. Most babies and toddlers suck their thumbs, but they may also suck on their fingers, hands, or items such as pacifiers. For the majority of children, this habit resolves on its own before it causes any lasting dental changes. When it continues past a certain age, however, it can begin to affect how the teeth and jaw develop — and that's when it's worth talking with a pediatric dentist.

The short answer: digit sucking and pacifier use are generally not a concern before age three. After that, if the habit is still active and vigorous, it's worth monitoring closely and, in some cases, addressing with a gentle intervention plan.

Why Children Suck Their Thumbs or Use Pacifiers

Sucking is a natural reflex that begins before birth. It provides comfort, helps babies self-soothe, and is a normal part of early development. Pacifiers are often introduced intentionally for this reason, and many children gravitate toward their thumbs or fingers on their own.

The habit typically fades naturally between ages two and four, as children develop other ways to manage stress or boredom. Most children who stop before their permanent teeth begin to emerge — usually around age six — show little to no lasting effect on tooth alignment or jaw structure.

When It Becomes a Dental Concern

The key factors are intensity, frequency, and duration. A child who rests a thumb passively in their mouth is less likely to cause dental changes than one who sucks aggressively for long stretches each day.

Habits that continue into the years when permanent teeth are erupting can contribute to:

• An open bite (front teeth that don't meet when the mouth is closed)
• Protrusion of the upper front teeth
• Narrowing of the upper arch
• Changes in the position of the lower teeth
• Shifts in jaw alignment over time

These changes are not inevitable, and they don't happen overnight. But they're also easier to address the earlier they're caught.

What to Expect During a Visit at Our Office

When parents bring up digit sucking or pacifier use at an appointment, Dr. Cortez will take a look at how the teeth and bite are developing and ask a few questions about the habit — how often it happens, in what situations, and whether the child has shown any interest in stopping.

There's no single visit that "treats" the habit. Instead, the conversation at that appointment shapes a plan. For younger children who are still within the normal window, the recommendation is often simply to monitor and check in at the next routine visit. For older children where the habit is more established, Dr. Cortez can discuss approaches that have worked for other families — including positive reinforcement strategies, habit reminder devices worn on the thumb, or referral to an orthodontist if bite changes have already begun.

Many families in Long Beach bring this up during a regular six-month checkup, and that's often the right time to start the conversation rather than waiting until a concern becomes urgent.

Tips for Helping Children Stop

When a child is ready and motivated, stopping is much easier. Some practical approaches that tend to help:

• Praise and positive reinforcement when the child avoids the habit, especially in situations that typically trigger it
• Identifying and addressing the emotional triggers (fatigue, anxiety, boredom) rather than focusing only on the behavior
• Using a bandage or glove as a gentle physical reminder — not a punishment
• Setting a clear, achievable goal together with the child
• Avoiding pressure or shame, which can make the habit harder to break

For pacifier use specifically, gradual weaning tends to work better than abrupt removal for many toddlers.

Frequently Asked Questions

**At what age should my child stop using a pacifier?** Most pediatric dentists recommend weaning from pacifier use by age two to three. The earlier, the lower the risk of dental changes.

**Is a pacifier better or worse than thumb sucking?** Pacifiers are often considered easier to discontinue because they can be taken away. Thumb sucking can be harder to stop but isn't inherently more harmful in the early years.

**My child only sucks their thumb when falling asleep. Is that still a problem?** Frequency and intensity matter. A passive, infrequent habit at bedtime is lower risk than active sucking throughout the day — but it's still worth mentioning at your next visit so Dr. Cortez can keep an eye on how the bite is developing.

**What if my child's teeth are already starting to shift?** Some early changes correct themselves once the habit stops, particularly in children whose permanent teeth haven't come in yet. Dr. Cortez will assess whether any follow-up with an orthodontist makes sense based on what's visible at the time of the exam.

**Do I need to make a special appointment to talk about this, or can I bring it up at a regular checkup?** A regular checkup is a fine time to bring it up. If it's your primary concern, you're welcome to mention it when scheduling so the appointment can be structured with enough time to discuss it properly.
