Most habits fade naturally, but some need a little help.
Sucking on a thumb, finger or soother is a natural comfort behaviour for babies and young children. Many children stop on their own in the preschool years. When the habit continues as adult teeth arrive, or is very intense, it can affect how the teeth and jaws develop. Other habits, such as tongue thrusting or nail biting, can also play a part.
Nanticoke parents who are wondering whether a habit is affecting their child’s teeth can ask at a checkup at our Port Dover office. The dentist can look for changes and suggest gentle, age-appropriate ways to help your child move on.
When to be concerned
Timing and intensity matter more than the habit itself.
Normal stages
Sucking habits are common and generally harmless in infants and toddlers. Many children stop between ages two and four. Concern increases if the habit continues when adult front teeth begin to come in, usually around age six, or if it is very frequent or forceful. Every child is different, so the dentist will look at your child’s mouth.
Signs it may be affecting teeth
Signs that a habit may be affecting development include front teeth that stick out, an open bite where front teeth do not meet, a narrow upper jaw or changes in speech. Calluses on the thumb may show how intense the habit is. The dentist can explain whether changes are present and if they are likely to self-correct.
Other habits
Other habits can influence teeth too.
Tongue thrusting and mouth breathing
Tongue thrusting, where the tongue pushes against the front teeth when swallowing or speaking, can contribute to an open bite. Mouth breathing, often related to allergies or enlarged tonsils, may affect jaw development. If you notice these, mention them. The dentist may suggest a referral to a physician or other specialist.
Nail biting and chewing objects
Nail biting, chewing pencils or clothing and grinding can wear teeth or cause chips. These habits are often linked to stress or boredom. Gentle redirection and helping your child find other outlets may help. The dentist can look for signs of wear and suggest strategies suited to your child’s age.
Helping your child
Encouragement works better than pressure.
Positive approaches
Praise your child when they are not sucking their thumb rather than scolding when they are. Identify triggers such as boredom, tiredness or anxiety, and offer comfort in other ways. Reward charts, gentle reminders and involving your child in the goal can help. Patience is important, since habits can take time to change.
When more help is needed
If a habit persists and is affecting the teeth, the dentist may suggest additional strategies or, in some cases, an appliance that discourages the habit. Referral to an orthodontist may be considered. The dentist will explain the options and discuss what is most suitable for your child’s age and situation.
Monitoring
Ongoing checkups track your child’s progress.
Regular checkups
The dentist will monitor your child’s teeth and bite at regular checkups. Many changes caused by habits improve after the habit stops, especially if it stops before adult teeth are fully in. Keep the dentist informed about how your child is progressing at home.
Supporting healthy development
Healthy development also depends on good oral hygiene, a balanced diet and regular dental visits. If an early orthodontic assessment is recommended, the dentist will explain why and what to expect. Working together, parents and the dental team can support your child’s growing smile.

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 on their own between ages two and four. If the habit continues as adult front teeth come in, usually around age six, it is worth discussing with the dentist to see whether it is affecting the teeth.
Can thumb sucking damage teeth permanently?
Prolonged or intense thumb sucking can affect tooth position and jaw development. Many changes improve after the habit stops, especially at a younger age. The dentist can assess your child and explain whether any treatment is likely to be needed.
Is a soother better than a thumb?
Soothers can be easier to take away than a thumb, but prolonged use can also affect teeth. The dentist can offer advice on when and how to reduce soother use as your child grows.
Should I use bitter nail polish or thumb guards?
Some families find these helpful as reminders, but they work best combined with positive encouragement. Ask the dentist for advice suited to your child’s age, personality and how strong the habit is.
What is tongue thrusting?
Tongue thrusting is when the tongue pushes forward against the teeth during swallowing or speaking. It can contribute to an open bite. The dentist may suggest a referral to a speech therapist or other specialist if it is affecting your child.
