Most habits fade, but some need a little help.
Thumb and finger sucking, pacifier use, nail biting, lip sucking and tongue thrusting are common in young children and often provide comfort. Many children stop on their own. When habits continue as permanent teeth arrive, or are particularly intense, they can affect how teeth line up and how the jaws develop.
Selkirk parents who are unsure whether a habit is a concern can raise it at their child’s checkup at our Port Dover office. The dentist can look for any effects on the teeth and bite, explain whether action is needed now, and suggest gentle strategies that suit your child’s age and temperament.
When to be concerned
Context determines whether a habit needs attention.
Age and intensity matter
Thumb sucking and pacifier use are normal in infancy and toddlerhood. Many children stop between ages two and four. Habits that continue as permanent front teeth come in, around age six, are more likely to affect alignment. How often and how intensely a child sucks also matters; passive resting causes less pressure than vigorous sucking.
Signs of effects on teeth
Front teeth that tip forward, a gap between upper and lower front teeth when biting, a narrow upper jaw or changes in speech may be signs that a habit is affecting development. Calluses on the thumb can show how frequently it is sucked. The dentist will examine your child and explain any effects they see.
Gentle strategies
Support works better than scolding.
Positive encouragement
Praise your child for times they are not sucking their thumb, rather than criticizing when they do. Sticker charts, small rewards and celebrating milestones can motivate some children. Involve your child in deciding to stop, especially if they are older. Gentle reminders and patience often work better than pressure, which can increase anxiety and the habit.
Understanding triggers
Notice when the habit happens, such as at bedtime, while watching TV, when tired or when anxious. Offering a comfort object, keeping hands busy or adjusting routines can help. If the habit seems linked to stress, addressing the source of worry may help. The dentist can suggest strategies tailored to your child’s patterns.
Further help
Some children need extra support.
Reminders and appliances
For children who want to stop but find it difficult, gentle reminders such as a bandage on the thumb or a glove at night may help. In some cases, the dentist may discuss a habit appliance, a small device placed in the mouth that makes sucking less satisfying. This is usually considered only for older children who are motivated to stop.
When to involve other professionals
Tongue thrusting or speech concerns may benefit from assessment by a speech-language pathologist. If habits seem related to anxiety or other behavioural concerns, your child’s physician may be able to help. If the bite has been significantly affected, an orthodontic assessment may be recommended once the habit has stopped.
Monitoring development
Many effects improve once the habit stops.
Regular checkups
Keep up with your child’s regular dental visits so the dentist can monitor how teeth and jaws are developing. Let the team know whether the habit has changed. Photos or records may be used to track progress. If concerns develop, the dentist can recommend next steps at the right time, including early orthodontic assessment.
When teeth improve on their own
If a habit stops before permanent teeth are fully in, some changes in tooth position may improve naturally. Others may need orthodontic treatment later. The dentist will explain what to expect for your child. Celebrate progress and stay patient, as breaking a comfort habit can take time and a few setbacks are common.

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 between ages two and four. Habits that continue as permanent front teeth come in, around age six, are more likely to affect the bite. The dentist can assess your child and advise whether it is time to encourage stopping.
Are pacifiers better than thumb sucking?
Pacifiers can also affect teeth if used for a long time, but they may be easier to wean because they can be taken away. The dentist can discuss strategies for reducing pacifier use at an age-appropriate time for your child.
Will thumb sucking damage my child’s teeth?
Prolonged or intense thumb sucking can cause front teeth to tip forward or create an open bite. Some effects improve once the habit stops. The dentist will examine your child and explain whether any changes need monitoring or treatment.
Should I use bitter nail polish to stop the habit?
Some families try it, but its effectiveness varies and some children find it upsetting. Positive encouragement and understanding triggers often work better. Discuss options with the dentist to find a strategy that suits your child’s age and personality.
What is a habit appliance?
A habit appliance is a small device placed in the mouth to make thumb sucking less satisfying. It is usually considered only for older children who want to stop but struggle. The dentist will explain whether it is appropriate for your child.
