Children develop oral habits for many reasons, and most of them are completely normal in the early years. The challenge is when those habits continue long enough to change the way the jaw grows and the teeth come in. Thumb sucking, tongue thrusting, and prolonged pacifier use are among the most common culprits, and addressing them at the right time can prevent the need for more extensive orthodontic treatment down the road.
At McCullum Orthodontics in Jeffersonville, Indiana, habit cessation is part of our broader approach to early interceptive orthodontics. Dr. Heather McCullum has advanced clinical training in identifying how oral habits affect jaw development and in providing the right tools to help children break those habits gently and effectively. She earned her DMD degree summa cum laude from the University of Louisville, graduated as valedictorian of her dental class, and brings over a decade of experience treating growing patients of all ages.
Oral habits are considered a concern when they persist beyond the age at which the jaw and teeth are most vulnerable to change. Many children stop thumb sucking and pacifier use on their own between the ages of two and four. When these habits continue past that window, however, they can begin to alter the shape of the palate, the position of the front teeth, and the relationship between the upper and lower jaws.
The American Association of Orthodontists notes that prolonged thumb sucking and pacifier use can cause protruding front teeth, open bite, and crossbite, all of which can create speech and swallowing difficulties and increase the risk of dental injury. Tongue thrusting, another common habit where the tongue pushes against the front teeth during swallowing or speech, can produce similar alignment problems if it is not addressed. The earlier these habits are identified and managed, the simpler and less invasive the correction tends to be.
Oral habits vary from child to child, and some are more immediately concerning than others. Dr. McCullum evaluates each child individually to determine whether a habit is likely to cause harm, how long it has been present, and what the most appropriate response is given the child’s age and jaw development.
The habits we most commonly address at McCullum Orthodontics include the following.
Identifying the right habit and understanding its impact on the developing bite is the first step toward an effective plan.
When behavioral approaches and gentle reminders are not enough to help a child break a persistent habit, Dr. McCullum may recommend a habit appliance. These are custom-made orthodontic devices, worn inside the mouth, that interrupt the habit by making it physically difficult to perform or by reducing the satisfaction the child associates with it.
Habit appliances can be either fixed or removable, depending on the child’s age, the severity of the habit, and how cooperative the child is likely to be with a removable device. Fixed appliances are cemented to the teeth and are generally more effective for younger patients or situations where consistent compliance is important. Removable appliances give older children more flexibility but require a higher level of consistency to work well.
Dr. McCullum will discuss which option makes the most clinical sense for your child and walk you through exactly what the appliance does and what to expect throughout the process. Habit appliances are temporary tools, and once the habit is broken, the focus shifts to monitoring how the teeth and jaw respond. In many cases, the jaw has enough natural flexibility to self-correct once the habit is eliminated. In other cases, palatal expanders or other early intervention treatments may be recommended to guide the jaw back toward healthy development.
If your child is still sucking their thumb or fingers past age four, using a pacifier regularly beyond age three, or if you have noticed their front teeth beginning to shift or a gap forming when their mouth is closed, it is worth scheduling a consultation. You do not need a referral from your child’s dentist to come in, and Dr. McCullum welcomes children for evaluations at any age. Early information is always better than waiting until a problem becomes more difficult to address.
