Thumb sucking, pacifier use and similar habits are a normal part of early childhood, and most children outgrow them without any lasting effect. A few habits last long enough to push on developing teeth and jaws, though. Knowing the difference helps parents decide when to wait and when to have a child’s bite evaluated.
Sucking Habits Can Change How Teeth Fit Together
Prolonged sucking puts steady pressure on a child’s teeth and jaws, and that pressure can change the bite. The American Association of Orthodontists explains that these changes can show up as early as 18 months, and its guidance on pacifiers and thumb sucking lists protruding front teeth, an open bite and a crossbite as common results.
An open bite leaves a gap between the upper and lower front teeth when the back teeth are closed. A crossbite means some of the upper teeth sit inside the lower ones. Either problem can affect speech, swallowing and the way the jaw grows.
Most Children Stop on Their Own
The same source notes that most children give up these habits somewhere between ages two and four. Parents of younger children rarely need to step in. Gentle reminders, praise and distraction at the moments a child reaches for a thumb or pacifier usually work better than pressure or scolding.
A habit that continues well past that window deserves attention. A front tooth that tilts outward, a gap that does not close or a child who chews mostly on one side are all worth mentioning to a Vestavia Hills orthodontist for kids, who can judge whether the bite is changing.
Other Habits Worth Watching
Sucking is not the only habit that can influence a growing smile. Parents may want to keep an eye on the following:
- Thumb or finger sucking that continues into the school years
- Pacifier use at nap time and bedtime well past toddlerhood
- Mouth breathing that happens most of the day, which a pediatrician may want to evaluate for allergies or airway concerns
- Pushing the tongue against the front teeth while swallowing or speaking
None of these habits means a child will need braces. They give an orthodontist more to consider when judging how the teeth and jaws are developing, and an evaluation with a Vestavia Hills orthodontist for kids can settle whether a habit has affected the bite at all.
Early Evaluation Opens More Options
According to the AAO, an orthodontist can help correct harmful oral habits, guide jaw growth and lower the risk of injury to protruding front teeth. Those benefits are easier to reach while a child is still growing, because young jaws respond to treatment more readily than fully grown ones.
Families who want to understand the timing can read about a child’s first visit to an orthodontist and what to expect when it happens.

A Local Practice With Decades of Experience
Dr. Dominique Backus has treated children and teens for 27 years, and Backus Smiles Orthodontics is conveniently located near Vestavia Hills in the Birmingham area. Her training includes a specialty certificate in orthodontics, and she volunteers with local children’s organizations, including Camp Smile-A-Mile.
Treatment Grows With the Child
Many children need nothing more than periodic monitoring while their permanent teeth come in. Others benefit from a small appliance that widens a narrow upper jaw, and the question of palate expanders comes up often for that reason.
When treatment is needed, the plan depends on age and on how the bite is developing. Younger patients may start with the options described under children’s orthodontics in Vestavia Hills, where the focus is on guiding growth while baby teeth are still present.
Older children can move toward clear braces or traditional appliances as their permanent teeth finish coming in. Every plan is built around the child’s own bite, so two children with the same habit can end up with very different treatment.
Habits that linger deserve attention, and parents who want a clear answer about a child’s bite can reach out to the team at Backus Smiles to talk through what they are seeing and what the next step might be.
