Supportive guidance can help children move past oral habits.
Sucking a thumb, finger or soother is a natural way for babies and young children to comfort themselves. Most outgrow the habit on their own. When it continues as adult teeth begin to arrive, though, it can affect how the teeth and jaws develop, sometimes leading to protruding front teeth, an open bite or a narrow upper jaw. Other habits, like tongue thrusting, can have similar effects.
Parents in Windham Centre who are unsure whether a habit is becoming a problem can ask our Port Dover dentists for advice. The dentist will look at your child’s teeth and bite, explain whether any changes are developing and suggest gentle, age-appropriate strategies to help your child stop when the time is right.
When to be concerned
Age and intensity matter more than the habit itself.
Normal comfort habits
Thumb and soother sucking are common and usually harmless in babies and toddlers. Many children stop on their own between ages two and four. Light, occasional sucking is less likely to cause problems than vigorous, frequent sucking. There is no need to panic if your preschooler still sucks a thumb at bedtime, but it is worth mentioning at checkups.
Signs a habit is affecting teeth
If the habit continues as permanent front teeth begin to erupt, typically around age six, it may start to affect their position. Signs include front teeth that tip forward, a gap between upper and lower front teeth when biting, or changes in the roof of the mouth. The dentist can spot these early and explain what they mean.
Other habits
Several habits can influence how a mouth develops.
Tongue thrusting and lip habits
Tongue thrusting, where the tongue pushes against the front teeth when swallowing or speaking, can contribute to an open bite or spacing. Lip sucking or biting can also affect tooth position. These habits are often subtle, so you may not notice them until the dentist points out changes. Mention any speech concerns, since a speech therapist may also be helpful.
Mouth breathing and nail biting
Frequent mouth breathing, often linked to allergies or enlarged tonsils, can influence jaw growth and tooth position over time. Nail biting and chewing on pencils can chip teeth or stress the jaw. If you notice these habits, mention them at your child’s visit. The dentist may suggest a check with your family doctor for breathing concerns.
Helping your child
Support usually works better than pressure.
Positive encouragement
Praise your child when they are not sucking their thumb, rather than scolding when they are. Many children suck for comfort when tired, anxious or bored, so offering other comforts, such as a favourite toy or a cuddle, can help. Reward charts, small goals and involving your child in the decision to stop often work better than strict rules or reminders.
Practical aids and timing
For night-time sucking, a glove or soft bandage on the hand can serve as a gentle reminder. Choose a calm period to work on the habit rather than during big changes like starting school or a new sibling. If the habit persists and is affecting the teeth, the dentist may discuss a habit appliance as a further option, explaining how it works.
Monitoring progress
Regular checkups help track changes.
Checking teeth and bite
The dentist will monitor your child’s bite and tooth position at regular visits, especially as adult teeth come in. Many minor changes improve once the habit stops, particularly in younger children whose jaws are still growing. Bringing up any progress or setbacks at each visit helps the dentist give advice that fits how things are actually going at home.
When to consider orthodontics
If the habit has caused significant changes, or a bite problem remains after the habit stops, the dentist may recommend an early orthodontic assessment. Not every child needs treatment, but early evaluation can help you understand options and timing. The dentist will explain any referral and what you and your child can expect from that appointment.
Planning your appointment
Ask at your child’s next visit.
Call our Port Dover office to discuss your child’s oral habits, or raise your questions at their next checkup. Windham Centre parents can describe when the habit happens and how long it has been going on.
Note when and how often the habit occurs, and mention any speech or breathing concerns you have noticed at home or school.

Oral habit questions
Have a question about your situation? Our team can help you plan a visit.
At what age should my child stop thumb sucking?
Many children stop on their own between two and four. Ideally the habit fades before adult front teeth erupt, around age six. If it continues beyond that, talk with the dentist about gentle ways to help your child stop.
Is a soother better than a thumb?
Soothers can be easier to wean from, since you can control their use. Both can affect teeth if the habit is prolonged. Avoid dipping soothers in sugar or honey, and aim to reduce use gradually as your child grows.
Will my child’s teeth move back after the habit stops?
Minor changes often improve, especially in younger children. More significant changes may need orthodontic treatment. The dentist will monitor the bite and let you know if an orthodontic assessment would be helpful at some stage.
What is a habit appliance?
A habit appliance is a small device fitted inside the mouth that makes thumb sucking less satisfying or reminds the tongue to stay in place. It is usually considered only when other strategies have not worked and the habit is affecting the teeth.
Should I worry about mouth breathing?
Frequent mouth breathing can be linked to allergies, enlarged tonsils or other airway issues. It may affect jaw growth over time. Mention it to the dentist, who may suggest a visit with your family doctor to explore the cause.
