Most habits fade on their own, but some need support.
Sucking a thumb, finger or pacifier is a natural soothing behaviour for babies and toddlers. Most children stop on their own as they grow. When a habit continues as permanent teeth begin to arrive, it can affect how front teeth line up and how the palate develops. Other habits, such as tongue thrusting or nail biting, may also matter.
Parents in Port Ryerse can ask about oral habits during their child’s visit to our Port Dover office. The dentist will look for any effects on teeth and bite and suggest supportive approaches, keeping in mind that pressure and punishment rarely help.
When to be concerned
Age and intensity both matter.
Normal in early childhood
Thumb and pacifier sucking are common and usually harmless in infants and young toddlers. Many children give up the habit by preschool age. During this period, the dentist will typically observe rather than intervene, unless sucking is very vigorous or changes are already visible.
When habits persist
If a habit continues as permanent front teeth erupt, often around age six, it can push teeth forward, create an open bite or narrow the upper jaw. Frequency, duration and intensity all influence the impact. The dentist will assess whether the habit is affecting development.
Effects on teeth
Look for these changes over time.
Changes in the bite
Upper front teeth tipping forward, a gap between upper and lower front teeth when biting, a narrow upper jaw or a crossbite can result from prolonged sucking habits. These changes may affect chewing, speech and appearance. Early detection allows more options for guidance.
Other signs
Calluses on the thumb or finger, speech changes such as a lisp, tongue thrusting when swallowing and mouth breathing can accompany oral habits. Mention these to the dentist, as they may relate to how teeth and jaws develop or suggest other factors worth checking.
Helping your child
Encouragement works better than pressure.
Positive approaches
Praise your child when they are not sucking rather than scolding when they are. Identify triggers such as tiredness, boredom or anxiety and offer alternatives like a comfort toy. Reward charts, gentle reminders and involving the child in setting goals can help. Patience is essential.
When extra help is needed
If a habit persists despite encouragement and is affecting teeth, the dentist may discuss reminder appliances or refer you to an orthodontist. These are typically considered only for older children who want to stop. Speech or swallowing concerns may involve a speech-language pathologist.
Follow-up
Monitoring tracks progress and development.
Regular checkups
The dentist will observe teeth and jaw development at routine visits. Photos or notes may be used to track changes. If the habit stops early, mild changes often improve on their own as permanent teeth come in. Continue to encourage good habits at home.
Long-term outlook
If changes persist after the habit stops, orthodontic treatment may be considered later. Early assessment can help plan timing. Keep the dentist informed about any changes you notice, such as difficulty chewing or speech concerns.

Thumb sucking and habit questions
Have a question about your situation? Our team can help you plan a visit.
When should my child stop thumb sucking?
Many children stop by preschool age. If the habit continues as permanent teeth arrive, it is worth discussing with the dentist, who can assess any effects.
Are pacifiers better than thumbs?
Pacifiers can be easier to wean from because they can be removed. Both can affect teeth if used for long periods. The dentist can advise on timing for stopping either.
Will thumb sucking damage permanent teeth?
Prolonged, intense sucking can affect the position of permanent teeth and the shape of the palate. Stopping early reduces the chance of lasting changes.
Should I use bitter nail polish?
Some families find reminder products helpful, but positive reinforcement is often more effective. Discuss options with the dentist and choose approaches your child agrees with.
Can habit appliances help?
For older children who want to stop but find it difficult, a reminder appliance may help. These are usually considered after other approaches have been tried.
