Caring for La Salette patients at our Port Dover office
See every dental service for La SaletteGentle habit help
Most children outgrow sucking habits, but some need a little help.
Thumb sucking, finger sucking and soother use are natural ways young children comfort themselves. Many stop on their own by preschool age. When habits continue as adult teeth come in, they can affect how teeth line up and how the jaws grow. Other habits, like tongue thrusting or nail biting, can also influence oral health.
Parents in La Salette can ask about oral habits during their child’s checkup at our Port Dover office. The dentist can look for effects on the teeth and bite and suggest supportive strategies that suit your child’s age and temperament.
When to be concerned
Age and intensity both matter.
Normal habits in young children
Sucking habits are common in babies and toddlers and usually cause little lasting effect. Many children naturally stop between two and four years of age. Light, occasional sucking is less likely to affect teeth than frequent, vigorous sucking.
Signs a habit is affecting teeth
If a habit continues as permanent front teeth come in, typically around age six, it may cause front teeth to tip forward, an open bite or a narrow upper jaw. The dentist will check for these signs and discuss whether intervention is recommended.
Other habits
Some habits are less obvious but still important.
Tongue thrusting and mouth breathing
Tongue thrusting, where the tongue pushes against the front teeth during swallowing or speech, can contribute to an open bite. Persistent mouth breathing may be linked to allergies or enlarged tonsils and can affect facial growth. The dentist may suggest evaluation by your child’s physician.
Nail biting and chewing objects
Nail biting, chewing pencils or other objects can chip teeth and stress the jaw. Lip biting or cheek chewing can cause sores. Mention any habits you notice so the dentist can check for effects and suggest ways to reduce them.
Helping your child
Support works better than pressure.
Positive encouragement
Praise your child when they are not sucking their thumb rather than scolding when they are. Children often suck their thumb when tired, bored or anxious, so offering comfort in other ways can help. Reward charts or small incentives may motivate older children.
Practical reminders
Gentle reminders, such as a bandage on the thumb or a soft glove at night, can help children who want to stop. Involve your child in the decision so they feel ownership. If a habit persists despite efforts, ask the dentist about additional options.
Further steps
Sometimes extra help is recommended.
Habit appliances
For persistent habits causing changes to teeth or the bite, the dentist may discuss a habit appliance, a small device placed in the mouth that makes sucking less satisfying. These are usually considered for older children who want to stop but find it difficult.
Monitoring development
Regular checkups allow the dentist to monitor how teeth and jaws are developing. If changes have occurred, they may improve on their own once the habit stops. In some cases, an orthodontic assessment may be recommended to evaluate the bite.

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 between two and four years of age. If the habit continues as permanent teeth come in, around age six, it may begin to affect the bite.
Is a soother better than thumb sucking?
Soothers can be easier to wean from because you can control access. Both can affect teeth if used for a long time. The dentist can discuss your child’s situation.
Can thumb sucking damage teeth?
Prolonged, vigorous sucking can cause front teeth to tip forward or create an open bite. Effects depend on frequency, intensity and duration. The dentist will check for changes.
What is a habit appliance?
A small device placed in the mouth that makes sucking less satisfying. It is usually considered for older children with persistent habits who want help stopping.
Will my child’s teeth correct themselves if they stop?
Some changes improve once the habit stops, especially if it ends early. Others may need orthodontic treatment. The dentist will monitor development and advise.
