Most oral habits fade naturally, but some need a little help.
Sucking thumbs, fingers or soothers is a natural way for babies and toddlers to comfort themselves. Most children stop on their own between the ages of two and four. When habits continue as adult teeth begin to arrive, they can affect how the teeth line up and how the jaws develop. Other habits, such as tongue thrusting, nail biting or lip sucking, can also have effects.
Langton parents who are wondering whether a habit is a concern can ask at their child’s checkup at our Port Dover office. The dentist will look for any changes in the teeth or bite, talk about your child’s routines and suggest supportive, age-appropriate ways to encourage change when needed, without shame or pressure.
When to be concerned
Age and intensity determine whether a habit matters.
Habits in early childhood
In babies and toddlers, sucking habits are normal and rarely cause lasting problems. As children approach school age and adult front teeth begin to erupt, frequent or vigorous thumb or finger sucking becomes more likely to influence tooth position. How often, how long and how hard a child sucks all play a role in whether changes develop.
Signs of effects on teeth
Signs that a habit may be affecting the mouth include front teeth that flare forward, a gap between upper and lower front teeth when biting, a narrow upper jaw or changes in speech. Calluses or red skin on the thumb can show how often the habit occurs. The dentist can check for these signs during regular visits.
Types of habits
Different habits affect the mouth in different ways.
Thumb, finger and soother use
Thumb and finger sucking place pressure on the front teeth and the roof of the mouth. Soother use generally has similar effects, though soothers can be easier to limit gradually. Using an orthodontically shaped soother and weaning by around age two or three may reduce effects. Never dip soothers in sugar, honey or syrup, which can cause decay.
Tongue thrusting and other habits
Tongue thrusting, where the tongue pushes forward against the teeth when swallowing or speaking, can contribute to an open bite. Nail biting, lip sucking, chewing on objects and teeth grinding may also affect teeth. Mention any habits you notice, as some may benefit from guidance by the dentist, a speech-language pathologist or other professionals as needed.
Helping your child
Encouragement works better than punishment.
Positive strategies
Praise your child when they are not sucking their thumb rather than scolding them when they are. Identify triggers, such as boredom, tiredness or anxiety, and offer alternatives like a favourite toy or a hug. Sticker charts and small rewards can motivate older children. Involving your child in setting goals helps them feel in control of the change.
Extra support
If gentle strategies do not work and the habit is affecting the teeth, the dentist may suggest reminders such as a bandage on the thumb at night or, in some cases, a habit appliance that makes sucking less satisfying. These are typically used only when a child is old enough and willing to stop. The dentist will explain the options.
Follow-up
Watching development over time is key.
Regular checkups
Regular dental visits allow the dentist to monitor tooth position and jaw growth as your child grows. Many minor changes caused by early habits improve on their own once the habit stops, especially if it ends before adult teeth fully arrive. The dentist can show you any changes and explain what to watch for at home.
When to involve an orthodontist
If the habit has caused significant changes in the bite or jaw, or if changes do not improve after the habit stops, the dentist may recommend an orthodontic evaluation. Early assessment can help determine whether treatment is needed and when it would be most effective. Ask about timing and what an orthodontist would look for.
Planning your appointment
Ask about habits from Langton.
Mention thumb sucking, soother use or other oral habits when you book your child’s checkup at our Port Dover office. The dentist can assess any effects and suggest practical next steps that suit your child’s age.
Note when and how often the habit happens, as this helps the dentist understand its likely impact on your child’s teeth.

Oral habit questions
Have a question about your situation? Our team can help you plan a visit.
At what age should thumb sucking stop?
Many children stop on their own between ages two and four. If thumb sucking continues as adult front teeth arrive, usually around age six, it becomes more likely to affect tooth position. The dentist can advise based on your child’s situation.
Are soothers better than thumb sucking?
Soothers can be easier to limit and wean than thumbs, but both can affect teeth if used for long periods. Weaning from a soother by around age two or three is often recommended. Avoid dipping soothers in sweet substances.
Will thumb sucking damage baby teeth?
Early thumb sucking rarely causes lasting damage to baby teeth. Concerns increase if the habit continues as adult teeth come in. Many changes improve once the habit stops, especially if it ends early in childhood.
Should I use a bitter nail polish?
Some families find bitter-tasting products helpful as a reminder for older children who want to stop. They work best alongside positive encouragement rather than as punishment. Ask the dentist whether this approach suits your child.
What is tongue thrusting?
Tongue thrusting is when the tongue pushes forward against or between the front teeth during swallowing or speaking. It can contribute to an open bite. The dentist may suggest an evaluation by a speech-language pathologist or orthodontist.
