Most habits fade on their own, but some need a little help.
Sucking a thumb, finger or soother is natural for babies and toddlers and often comforts them. Many children stop on their own in the preschool years. When the habit continues as adult teeth arrive, or is very intense, it can push front teeth forward, narrow the upper jaw or create an open bite. Other habits, like tongue thrusting, nail biting or lip sucking, can also affect teeth.
Long Point parents wondering whether a habit is affecting their child’s teeth can ask our Port Dover team. The dentist can assess the effects and suggest supportive, age-appropriate strategies.
Should you worry?
Timing and frequency matter most.
Age and intensity
Occasional thumb sucking in toddlers usually causes no lasting harm. Concerns increase when the habit continues as permanent teeth erupt, happens often during the day or is vigorous enough to leave marks on the thumb. The dentist will ask about when and how often your child sucks their thumb or uses a soother.
Signs of changes in the teeth
Front teeth that tip forward, a gap between upper and lower front teeth when biting, a narrow palate or speech changes may suggest the habit is affecting development. The dentist examines the bite and may suggest monitoring, habit strategies or referral if changes are significant.
Strategies
Encouragement works better than pressure.
Positive reinforcement
Praise your child for not sucking their thumb rather than scolding when they do. Sticker charts, small rewards and gentle reminders can help. Involve your child in setting goals. Pressure or punishment often increases anxiety and may make the habit harder to break.
Understanding triggers
Notice when the habit happens, such as at bedtime, when tired, bored or anxious. Offering a comfort object, keeping hands busy or adjusting bedtime routines can help. If anxiety seems to drive the habit, addressing the underlying stress may be more effective.
Other habits
Several habits can influence growing teeth.
Tongue thrusting and mouth breathing
Tongue thrusting, where the tongue presses against the front teeth when swallowing, can contribute to an open bite. Mouth breathing may be linked to allergies or enlarged tonsils and can affect jaw development. The dentist may suggest a referral to a physician, speech therapist or orthodontist if needed.
Nail biting and lip habits
Nail biting can chip teeth and introduce bacteria. Lip sucking or chewing can push teeth out of position. These habits often respond to awareness and positive reinforcement. The dentist can explain whether they are affecting your child’s teeth and how to help.
Next steps
Some children benefit from extra support.
Habit appliances
If a habit persists despite encouragement and is affecting the teeth, a habit appliance may be discussed. These fit inside the mouth and serve as a reminder. They are typically used for older children who want to stop. The dentist will explain how they work and any drawbacks.
Ongoing monitoring
Regular checkups allow the dentist to track changes in the bite as your child grows. Many changes improve once a habit stops. If problems persist, an orthodontic assessment may be recommended. Keep visits consistent even if your family spends only part of the year at Long Point.

Oral habit questions
Have a question about your situation? Our team can help you plan a visit.
When should my child stop sucking their thumb?
Many children stop on their own in the preschool years. If the habit continues as adult teeth come in, or is very frequent, ask the dentist whether it is affecting the teeth.
Is a soother better than thumb sucking?
Soothers can be easier to wean from because they can be removed, but prolonged use can still affect teeth. Ask the dentist about timing and strategies for reducing use.
Will my child’s teeth go back to normal after stopping?
Some changes improve once the habit stops, especially in younger children. Others may need orthodontic treatment. The dentist will monitor and advise based on your child’s development.
Do bitter nail polishes help?
Some families find them useful as a reminder, but they work best alongside positive reinforcement. Discuss options with the dentist to choose an approach suited to your child.
What is a habit appliance?
It is a device placed in the mouth to discourage thumb sucking or tongue thrusting. It is usually considered when other strategies have not worked and the habit is affecting the teeth.
