Little blonde boy sucking on his thumbThumb-sucking and pacifier use are common oral habits among infants and young children, which develop from innate reflexes in the womb.

For many infants, sucking a thumb or pacifier provides comfort, joy, and a sense of security during their early developmental stages. However, thumb-sucking and pacifier use can have significant implications for dental health if prolonged.

According to the American Dental Association, nearly 75 percent of infants engage in thumb-sucking or pacifier use during their first year of life, compromising their dental development.

Puyallup Pediatric Dentistry can help you understand the dental impact of these habits to maintain healthy oral development in your children.


Thumb-sucking is normal among infants and young children, providing a source of comfort and self-soothing. While it is a natural reflex, prolonged thumb-sucking can cause various dental issues, affecting the long-term oral health of your child. Parents and caregivers have the ability to prevent potential dental complications and nurture healthy habits. Here are some thumb-sucking effects you want to avoid.

Dental Misalignment

One of the primary concerns associated with prolonged thumb-sucking is dental misalignment. As the child sucks their thumb, it puts pressure on the teeth and oral structures, disrupting the natural alignment of the teeth.

While signs of misalignment may not show instantly, delaying professional intervention can cause open bite, crossbite, or overbite. The best way to avoid such issues is through regular visits to Dr. Hersey or orthodontist to correct the problem.

Palatal Changes

Another typical effect of thumb-sucking is changes to the shape and structure of the palate or the roof of the mouth. As mentioned, thumb-sucking puts persistent pressure on the palate, causing the development of a high-arched palate. These alterations can affect speech and challenges with pronunciation or articulation.

Speech Impediments

Besides affecting the palate, prolonged thumb-sucking can affect speech development. Changes in oral structures and muscle function because of thumb-sucking cause articulation disorders or speech impediments.

If your child sucks their fingers excessively, it may cause difficulties in producing certain sounds or forming words correctly. Young children with speech impediments often require speech therapy to address these challenges.

Dental Malocclusions

Malocclusions, or irregularities in the alignment of the upper and lower teeth when the jaw is closed, are also common effects of thumb-sucking. These malocclusions can manifest as crowded teeth, protruding front teeth, or improper positioning of the molars.

While malocclusions are not a concern initially, they can contribute to chewing difficulties, jaw pain, and an increased risk of dental issues such as tooth decay and gum disease if left untrained.

Oral Hygiene Concerns

Thumb-sucking may also pose challenges for maintaining proper oral hygiene. Children who suck their thumbs introduce bacteria from their hands into their mouths unintentionally, increasing the risk of dental infections and cavities.

Also, thumb-sucking can make it difficult for children to brush their teeth effectively, causing plaque buildup and dental decay if oral hygiene practices are not reinforced.

Pacifier Use

Pacifiers are commonly used soothing tools for infants that play a significant role in early childhood development. However, prolonged pacifier use can cause various oral health issues. Here are some pacifier effects to help you make an informed decision for your child.

Dental Impact

Prolonged pacifier use can exert significant pressure on the developing oral structures, causing malocclusions and misalignments of the teeth and jaw. The constant sucking motion alters the positioning of teeth, causing issues such as open bite, overbite, or crossbite. In addition, excessive pacifier use can affect the growth and development of the palate, resulting in narrowed arches and other dental complications.

Speech Development

Another drawback of extended pacifier use is speech development issues in young children. Having a pacifier in the mouth for prolonged periods can hinder the proper formation of sounds and impede speech articulation development. Children who use pacifiers extensively may exhibit delays in speech milestones, affecting their ability to communicate effectively.

Ear Infections

Research into child oral health suggests a potential link between prolonged pacifier use and an increased risk of ear infections in infants and young children. The continuous sucking motion creates negative pressure in the middle ear, making children more susceptible to conditions such as otitis media. Frequent ear infections cause discomfort and affect hearing and overall well-being.

Orthodontic Concerns

Orthodontic specialists or pediatric dentists often caution against prolonged pacifier use because of its potential long-term effects on dental alignment and bite function. If your child continues using pacifiers beyond infancy, you may require orthodontic interventions later to correct the resulting malocclusions and alignment issues. We recommend early intervention to discourage pacifier use in order to mitigate the need for extensive orthodontic treatment in the future.

Social Implications

While dental and physical effects are easily detected, prolonged pacifier use can have social implications for children. As they age, dependence on pacifiers usually interferes with their social interactions and self-confidence, especially when pacifiers are not socially acceptable. Determine specific times for pacifier use to help your child transition smoothly into age-appropriate behaviors and social norms.

FAQS About Thumb-Sucking and Pacifier Use

When Do Infants Begin Thumb-Sucking or Pacifier Use?

Thumb-sucking often begins in the womb, as infants seek oral stimulation instinctively for comfort and self-soothing. Many infants exhibit these oral habits shortly after birth and may continue into early childhood. Pacifiers are often introduced in the first weeks of life to help bring comfort.

How Can I Help My Child Stop Thumb-Sucking or Pacifier Use?

As mentioned, encouraging positive reinforcement, providing alternative comfort items, and praising their efforts to stop can help them overcome thumb-sucking or pacifier dependence. Your pediatric dentist can also recommend gradual reduction strategies like involving your child in decision-making, which is effective in breaking the habit.

What Are the Consequences of Prolonged Pacifier Use and Thumb-Sucking?

Prolonged thumb-sucking or pacifier use can cause dental misalignments, such as open bite, overjet, or crossbite. These habits may also affect the development of the palate and jaw, potentially necessitating orthodontic intervention in the future.

At What Age Should I Be Concerned About Thumb-Sucking or Pacifier Use?

Most children naturally outgrow thumb-sucking or pacifier use by age four. However, if these habits persist beyond this age or are intense and frequent, it may be advisable to seek guidance from a dental specialist to address potential concerns.
