Pacifier, Thumb Sucking and Teeth: Effects on Malocclusions in Children in Lugano
Many parents wonder whether using a pacifier or sucking a thumb can really affect the development of a child’s teeth. These are very common habits in early childhood, often helpful in calming and comforting children, but if they persist beyond a certain age, they can influence the growth of dental arches and proper tooth alignment.
At the Renata Bakaj Orthodontic Studio in Lugano, special attention is given to so-called oral habits, because identifying and managing them early can often prevent more complex orthodontic treatments later on.
Why children use pacifiers or suck their thumb
Sucking is a natural reflex in newborns and young children.
Pacifiers and thumb sucking help children to:
- calm down
- fall asleep
- feel reassured
During the first years of life, these habits are not a concern. They become problematic when they continue beyond the age of 2–3 years.
When sucking habits become a problem for teeth
If thumb sucking or pacifier use continues over time, constant pressure is applied to the teeth and developing bones.
Possible consequences include:
- anterior open bite, where the front teeth do not touch
- narrow palate, caused by upward pressure
- protruding teeth, especially the upper incisors
- alterations in proper bite closure
These issues do not always resolve spontaneously with growth.
Pacifier or thumb: is there a difference?
From an orthodontic perspective, both habits can have similar effects, but with some differences.
Pacifier
- easier to control and remove
- if orthodontic and used correctly, it may have a lower impact
- should still be discontinued by the age of 2–3
Thumb sucking
- more difficult to manage
- often occurs more frequently and for longer periods
- commonly associated with more pronounced effects
In both cases, duration and intensity are key factors.
Signs parents should look out for
Some signs may indicate that sucking habits are affecting dental development:
- front teeth that do not meet
- very protruding upper incisors
- narrow upper dental arch
- difficulty pronouncing certain sounds
- mouth breathing
An orthodontic consultation allows for an accurate assessment.
When and how to stop these habits
Pacifier or thumb sucking should be discontinued in a gradual and non-traumatic way.
Helpful strategies include:
- avoiding scolding or punishment
- positively reinforcing progress
- limiting the habit to specific moments (e.g. only at bedtime)
- involving the child in the process
In more persistent cases, the orthodontist may suggest additional supportive strategies.
The role of interceptive orthodontics
When habits have already caused changes, interceptive orthodontics can help guide jaw growth and correct malocclusions at an early stage.
Possible tools include:
- removable appliances
- palatal expanders
- functional devices
Early intervention often means avoiding longer and more complex treatments during adolescence.
The importance of a calm and supportive approach
A child’s emotional well-being is essential.
Addressing these habits with patience and support leads to better outcomes and helps maintain a positive relationship with dental care.
At the Bakaj Studio, the approach is always empathetic and respectful of each child’s pace.
