Most children outgrow sucking habits, but some need a little support.
Thumb sucking, finger sucking and pacifier use are natural self-soothing behaviours for babies and toddlers. Most children stop on their own between ages two and four. When habits continue as permanent teeth arrive, they can push teeth forward, create an open bite or affect jaw development. Other habits, like tongue thrusting or lip sucking, can have similar effects.
Brantford parents with concerns about a child’s oral habits can discuss them during a checkup at our Port Dover office. The dentist will look for any effects on the teeth and bite, explain whether action is needed now and suggest gentle, encouraging strategies that respect your child’s pace.
When to be concerned
Age and intensity matter more than the habit itself.
Normal stages of sucking habits
Sucking is common and comforting for young children, and in the early years it rarely causes lasting problems. Concerns tend to increase if the habit continues after permanent front teeth begin coming in, usually around age six. How often and how hard a child sucks also matters, since gentle, occasional sucking has less effect than frequent, vigorous habits.
Signs the habit may be affecting teeth
The dentist may notice upper front teeth tipping forward, a gap between upper and lower front teeth when biting, a narrow upper jaw or changes in speech. Calluses on the thumb can also indicate frequent sucking. If these signs appear, the dentist will explain how the habit may be contributing and whether guidance or monitoring is recommended.
Supporting change
Encouragement works better than pressure.
Positive reinforcement
Praise your child when they are not sucking, rather than scolding when they are. Sticker charts, small rewards for habit-free days and involving your child in setting goals can motivate change. Avoid shaming or punishment, which can increase anxiety and make the habit harder to break. Children respond best when they feel supported and in control.
Understanding triggers
Notice when the habit happens, such as when tired, bored, anxious or watching television. Offer alternatives, like holding a soft toy or keeping hands busy. Comfort your child during stressful times in other ways. Understanding triggers helps you address the reasons behind the habit, not just the behaviour itself.
Professional guidance
The dental team can add encouragement and options.
Talking with your child
Sometimes hearing from the dentist helps children understand why stopping matters. The dentist can explain in simple terms how the habit affects teeth and offer encouragement. Children often respond well to a neutral adult. This conversation works best when the child is ready and motivated rather than pressured into stopping.
Appliances and referrals
For persistent habits, the dentist may discuss a habit appliance, which makes sucking less satisfying and serves as a reminder. These are usually considered only when other approaches have not worked. If tongue thrusting or speech concerns are present, referral to a speech-language pathologist or orthodontist may be suggested.
Monitoring progress
Regular checks show whether teeth are adjusting.
Checking development over time
Once the habit stops, some bite changes may improve on their own as teeth and jaws continue to grow. The dentist monitors development at regular checkups and explains whether orthodontic evaluation is needed. For Brantford families, these checks can happen during routine visits without requiring extra trips to Port Dover.
Celebrating success
Celebrate milestones and acknowledge your child’s effort. Relapses are common, especially during stress, and are not a reason for discouragement. Continue gentle support and share progress with the dentist at each visit. Patience and encouragement usually help children move past these habits successfully over time.

Oral 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 between ages two and four. Concerns increase if the habit continues as permanent teeth come in, around age six. The dentist can assess whether the habit is affecting your child’s teeth and offer guidance.
Is a pacifier better than thumb sucking?
Pacifiers can be easier to limit and wean, but prolonged use can also affect teeth. Gradually reducing pacifier use as your child grows is often recommended. The dentist can suggest timing and strategies.
Will my child’s teeth go back to normal?
Some changes improve once the habit stops, especially at younger ages. Others may need orthodontic treatment. The dentist will monitor development and explain whether intervention might be needed later.
Should I use bitter nail polish?
Some families find it helpful as a reminder, but it works best alongside encouragement and understanding triggers. Avoid making it feel like punishment. The dentist can suggest options that suit your child.
What is tongue thrusting?
Tongue thrusting is when the tongue pushes against or between the teeth during swallowing or speech. It can affect tooth position. The dentist may suggest a speech-language pathologist for assessment and exercises.
