Most babies are born with natural sucking reflexes, finding comfort in pacifiers or their own thumbs. While these habits provide security and soothing effects for infants and toddlers, they can influence dental development when continued beyond a certain age. Understanding how these common habits affect your child’s oral health helps you make informed decisions about when to encourage breaking these habits.
At ABC Children’s Dentistry in Voorhees, NJ, we work closely with parents to monitor developmental concerns related to pacifier use and thumb-sucking. Our team takes a gentle, supportive approach to helping families transition away from these habits when the time is right, ensuring your child’s dental development stays on track for a healthy, beautiful smile.
How These Habits Affect Dental Development
Thumb-sucking and pacifier use during the first few years of life rarely cause dental problems. In fact, the American Academy of Pediatrics considers these habits normal for infants and young children. However, prolonged sucking habits that continue as permanent teeth begin to emerge can lead to dental concerns.
When a child sucks their thumb or uses a pacifier, they create pressure against developing teeth and the roof of the mouth. This constant pressure can affect how teeth and jaws develop over time. The most common dental issues associated with prolonged sucking habits include:
- Anterior open bite – where front teeth don’t meet when biting down
- Protruding front teeth that push forward
- Narrowed upper dental arch creating crowding issues
- Changes in the roof of the mouth (palate)
- Speech difficulties, particularly with “s,” “z,” and “th” sounds
- Misalignment of the jaw (malocclusion)
It’s important to note these changes typically only occur with persistent habits that continue past age 3-4, when permanent teeth begin developing beneath the gums.
When Should These Habits Stop?
Most children naturally outgrow thumb-sucking and pacifier use between the ages two and four as they develop other coping skills and become more socially aware. From a dental perspective, the American Academy of Pediatric Dentistry recommends discouraging these habits by age 3.
If your child continues sucking habits beyond age four, it’s time to work more actively toward breaking the habit. By this age, prolonged sucking may begin affecting permanent teeth development. Though each child develops differently, dental concerns become more likely with:
- Intense sucking versus passive sucking (where the thumb or pacifier simply rests in the mouth)
- Frequent, consistent sucking throughout the day and night
- Continuation of the habit beyond ages four and five
Remember, most dental changes from early childhood sucking habits are reversible if the habit stops before permanent teeth fully emerge. The earlier the habit stops, the better chance teeth have to return to their proper positions naturally.
Tips for Breaking Sucking Habits
Breaking thumb-sucking or pacifier habits requires patience, positive reinforcement, and consistency. Harsh criticism or punishment typically backfires, creating anxiety that may actually increase a child’s reliance on these comfort mechanisms.
Instead, try these gentle strategies:
- Praise and reward your child when they don’t suck their thumb or use a pacifier
- Identify anxiety triggers that prompt sucking and help develop alternative coping skills
- Apply a bitter-tasting (but safe) solution recommended by your pediatric dentist to the thumb
- For pacifiers, gradually restrict use to certain times like bedtime, before eliminating completely
- Create a calendar with stickers to track success and celebrate milestones
- Enlist the support of your pediatric dentist to explain the importance to your child
For particularly persistent habits, your pediatric dentist may recommend a special dental appliance that serves as a reminder not to suck the thumb or fingers.
