Most habits fade naturally, but some need a helping hand.
Sucking on a thumb, finger or pacifier is a natural way for babies and young children to soothe themselves. Most children stop on their own as they grow. When strong or frequent sucking continues as adult teeth begin to arrive, it can push front teeth forward, narrow the upper jaw or create an open bite. Other habits, such as tongue thrusting or nail biting, can also affect teeth.
Hillcrest parents who are concerned about a habit can bring their child to our Port Dover office. The dentist will check whether the habit is affecting teeth or jaw growth and suggest supportive, age-appropriate strategies that respect your child’s feelings and fit your family’s routines at home.
Is it a concern?
Timing and frequency influence the effect on teeth.
Age and intensity matter
Many children stop sucking habits between the ages of two and four. Continuing occasionally into the preschool years may cause little lasting effect, but vigorous or frequent sucking as permanent teeth erupt is more likely to influence alignment. The dentist will look at how the teeth and jaw are developing and whether any changes have already begun, which helps guide advice.
Other habits to notice
Tongue thrusting, where the tongue pushes against the front teeth when swallowing or speaking, can contribute to an open bite. Lip sucking, cheek biting, nail biting, chewing on objects and mouth breathing may also affect teeth or gums. Mention any habits you have noticed, even if they seem minor, so the dentist can consider their potential impact.
Assessment
The dentist looks for effects and possible causes.
Teeth and bite changes
The dentist examines how the front teeth meet, whether they are pushed forward, whether there is a gap when the back teeth bite together and whether the upper jaw appears narrow. They may also look at the thumb or finger for signs of frequent sucking. These findings help determine whether the habit is causing changes that warrant action.
Underlying reasons
Habits often serve a purpose, such as comfort, falling asleep or managing stress or boredom. Mouth breathing may relate to allergies or enlarged tonsils, which might need medical evaluation. Understanding why the habit continues helps choose an approach. The dentist may ask when the habit happens most and what has already been tried at home.
Supportive strategies
Gentle, positive approaches tend to work best.
Positive encouragement
Praise your child for times they do not suck their thumb rather than criticizing when they do. Sticker charts, small rewards and talking about being a big kid can help motivate older children. Avoid shaming, teasing or punishment, which can increase stress and make the habit harder to break. Involving the child in choosing goals often makes them more willing to try.
Practical reminders
Offer alternative comfort items at bedtime, keep hands busy during habit-prone times such as watching television and use gentle reminders agreed with your child. A bandage or glove at night may serve as a reminder for some children. If stress or anxiety seems to drive the habit, addressing those feelings may be more helpful than focusing on the habit itself.
Further help
Additional support is available when needed.
Appliances as a reminder
For older children who want to stop but find it difficult, the dentist may discuss a habit appliance, a small device fitted behind the upper teeth that acts as a physical reminder. It is generally considered only when a child is ready and motivated. The dentist will explain how it works, how long it might be worn and what to expect.
Referral and follow-up
If a habit has already affected the bite or jaw development, the dentist may recommend monitoring or referral to an orthodontist. Speech or swallowing concerns related to tongue thrusting may benefit from a speech-language pathologist. Mouth breathing linked to airway issues may warrant a physician’s assessment. The dentist can help coordinate these referrals and explain what each one is for.

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 by around age four. If the habit continues as permanent teeth begin to come in, or is vigorous and frequent, it is worth discussing with the dentist. Each child is different, so the dentist will assess the effects.
Is a pacifier better than a thumb?
Pacifiers can be easier to limit and wean than thumb sucking, since they can be taken away. Both can affect teeth if used frequently and for a long time. The dentist can advise on reducing pacifier use at an appropriate age.
Will thumb sucking damage my child’s teeth permanently?
Some changes may correct themselves once the habit stops, especially if it ends before permanent teeth arrive. Longer or more intense habits may cause lasting changes that need orthodontic treatment. Early assessment helps guide decisions.
Should I use bitter nail polish?
Some parents find bitter-tasting products helpful as a reminder, but they work best when the child is willing to stop and understands why. Combining them with positive encouragement is generally more effective than relying on them alone.
What is tongue thrusting?
Tongue thrusting is when the tongue pushes forward against or between the front teeth during swallowing or speech. It can contribute to an open bite. The dentist may suggest monitoring or referral to a speech-language pathologist for exercises.
