See every dental service for VanessaGentle help with habits
Most oral habits fade naturally, but some need a little support.
Sucking on thumbs, fingers or pacifiers is a natural way for babies and young children to soothe themselves. Most children stop on their own between the ages of two and four. When habits continue as adult teeth arrive, though, they can affect how teeth line up and how the jaws develop. Other habits, like tongue thrusting, nail biting or lip sucking, may also matter.
Families in Vanessa can ask about oral habits during their child’s checkups at our Port Dover office. The dentist will look at your child’s teeth and bite, explain whether the habit seems to be causing changes, and suggest gentle, practical ways to help if it does, without shame or pressure.
When to be concerned
Age, frequency and intensity all matter.
Normal in early years
In infants and toddlers, thumb and pacifier sucking are common and usually harmless. Many children stop naturally as they find other ways to comfort themselves. Occasional, gentle sucking is less likely to cause problems than frequent, vigorous sucking. The dentist will ask how often the habit happens and when, such as only at bedtime or throughout the day.
Signs a habit may be affecting teeth
If the habit continues once adult front teeth start to come in, usually around age six, it may push teeth forward, create an open bite where front teeth do not meet, narrow the upper jaw or affect speech. The dentist can spot early signs during checkups and explain whether changes are developing that need attention.
Other habits
Several habits can influence growing mouths.
Tongue thrust and mouth breathing
Tongue thrusting, where the tongue pushes forward against the teeth when swallowing or speaking, can contribute to open bites and spacing. Chronic mouth breathing, sometimes linked to allergies or enlarged tonsils, may affect jaw development and is associated with snoring. If you notice these, mention them to the dentist, who may suggest a check with your child’s physician.
Nail biting and lip habits
Nail biting, chewing on pencils or clothing and lip sucking or biting can chip teeth, irritate gums and sometimes affect alignment. Grinding during sleep is common in children and often fades, but should be mentioned at checkups. The dentist will consider all habits together when assessing your child’s teeth and development, since several often occur at once.
Helping your child
Support works better than pressure.
Positive encouragement
Praise your child when they are not sucking their thumb or using a pacifier, rather than scolding them when they do. Many children suck when tired, bored or anxious, so noticing those moments and offering comfort in other ways can help. A simple reward chart or small celebrations for habit-free days can motivate some children, especially older ones.
Reminders and alternatives
Gentle reminders, a bandage on the thumb, mittens at night or a favourite stuffed toy to hold can help children become more aware of the habit. Involve older children in choosing strategies so they feel in control. If a child is stressed by changes at home or school, focus on comfort first and approach habit-breaking gradually.
When more help is needed
Most children stop with support, but some need extra help.
Dental guidance and monitoring
The dentist can talk with your child in a friendly way about the habit and how it affects their teeth, which some children respond to better than reminders from parents. Regular checkups allow the dentist to monitor any changes in the bite. Many mild changes improve once the habit stops, especially if it stops before adult teeth are fully in.
Appliances and referrals
For persistent habits that are affecting the teeth or jaws, the dentist may discuss a habit appliance or refer your child for an orthodontic assessment. Speech therapy may help with tongue thrust. The dentist will explain the reasons for any recommendation and work with you to find an approach that suits your child and family.

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 on their own between ages two and four. If the habit continues as adult front teeth arrive, around age six, it is worth discussing with the dentist, since it may begin to affect tooth position.
Is a pacifier better than a thumb?
Pacifiers can be easier to limit and wean than thumbs, but both can affect teeth if used frequently and for many years. The dentist can advise on weaning strategies suited to your child’s age and temperament.
Will my child’s teeth go back to normal after the habit stops?
Mild changes often improve once the habit stops, especially before adult teeth are fully in. More significant changes may need orthodontic treatment later. The dentist will monitor the bite at regular checkups and advise you on whether any further steps are worthwhile.
Should I use bitter nail polish to stop thumb sucking?
Some families find bitter-tasting products helpful as a reminder, but they work best alongside positive encouragement. Ask the dentist or your child’s physician before using any product, and avoid strategies that cause shame or distress.
Can mouth breathing affect my child’s teeth?
Chronic mouth breathing may affect jaw development and is linked with snoring and dry mouth. If you notice it, mention it to the dentist and your child’s physician, who may check for allergies or enlarged tonsils.
