Expert Insights from Dr. Srimay Samal
Thumb sucking is a common and natural habit in infants and young children. While it often provides comfort and security during early development, prolonged thumb sucking can affect a child’s dental health and jaw growth. According to Dr. Srimay Samal, pediatric dental expert, knowing when thumb sucking is normal and when intervention is needed helps parents protect their child’s smile and overall oral development.
Why Do Children Suck Their Thumbs?
Thumb sucking is a natural reflex that often begins before birth. Children may suck their thumbs to:
Feel calm and secure
Self-soothe during stress or tiredness
Help fall asleep
Adjust to new environments
Dr. Samal explains,
“Thumb sucking in infancy and early toddler years is completely normal and usually not a cause for concern.”
When Is Thumb Sucking Considered Normal?
Thumb sucking is generally harmless:
From infancy up to 3–4 years of age
When it occurs mainly during sleep or stressful moments
When it does not affect speech, eating, or tooth alignment
Most children naturally outgrow the habit as they develop emotional coping skills.
When Does Thumb Sucking Become a Dental Concern?
According to Dr. Srimay Samal, thumb sucking may require attention if it:
Continues after age 4 or 5
Becomes frequent or forceful
Persists after permanent teeth begin to erupt
Causes visible changes in teeth or jaw alignment
Possible Dental Effects Include:
Protruding front teeth
Open bite (gap between upper and lower teeth)
Misaligned teeth
Changes in jaw growth
Speech difficulties
“Prolonged thumb sucking can interfere with natural dental development and may lead to orthodontic issues if left unaddressed,” says Dr. Samal.
Signs Parents Should Watch For
Parents should seek professional guidance if they notice:
Thumb sucking throughout the day
Redness or calluses on the thumb
Difficulty pronouncing certain sounds
Changes in tooth position
The habit continuing into school age
Early intervention can prevent long-term complications.
How Parents Can Help Children Stop Thumb Sucking
Dr. Srimay Samal recommends a gentle, positive approach:
✔ Positive Reinforcement
Praise and encourage your child when they avoid thumb sucking.
✔ Identify Triggers
Thumb sucking often occurs during stress, boredom, or fatigue—addressing these triggers can help.
✔ Provide Comfort Alternatives
Offer toys, blankets, or calming activities for emotional reassurance.
✔ Use Gentle Reminders
Avoid punishment or shaming, which can increase anxiety and worsen the habit.
✔ Dental Appliances (If Needed)
In persistent cases, a pediatric dentist may suggest a simple oral appliance to discourage thumb sucking.
“Support and patience work far better than pressure. Every child responds differently,” Dr. Samal emphasizes.
When Should You Visit a Paediatric Dentist?
A dental consultation is recommended if:
Thumb sucking continues beyond age 5
Teeth alignment begins to change
Speech development is affected
Parents find it difficult to stop the habit
Early dental visits help guide proper oral development and reduce the need for future orthodontic treatment.
Dr. Srimay Samal’s Expert Advice
“Thumb sucking is part of early childhood development, but prolonged habits can impact dental health. With early awareness and professional guidance, children can break the habit naturally and maintain healthy smiles.”
Final Thoughts
Thumb sucking is normal in early childhood—but knowing when to step in makes all the difference. With gentle guidance and timely paediatric dental care, parents can ensure their child’s teeth, jaw, and speech develop correctly.
