Prolonged pacifier use can lead to dental issues such as misaligned teeth and bite problems, especially if used beyond age two to four.
Understanding How Pacifiers Influence Dental Health
Pacifiers are a common tool parents use to soothe infants and toddlers. They provide comfort, reduce crying, and even lower the risk of sudden infant death syndrome (SIDS). But there’s a big question looming for many parents: Do pacifiers affect teeth? The answer isn’t a simple yes or no. It depends on how long and how often the pacifier is used, as well as the child’s age.
When a baby sucks on a pacifier, it exerts pressure on the developing teeth and jaws. This sucking motion is natural; infants have a strong sucking reflex that helps with feeding. However, extended or excessive use of pacifiers can push teeth out of their natural alignment. This can cause dental problems such as open bite, crossbite, or overjet.
The American Dental Association (ADA) notes that occasional pacifier use in early infancy generally does not cause harm. Problems tend to arise when children continue using pacifiers past the age of two or three years old. By this time, permanent teeth start developing underneath baby teeth, and prolonged sucking habits can interfere with their proper eruption.
Types of Dental Issues Linked to Pacifier Use
The main dental concerns linked to pacifier use involve changes in tooth positioning and bite alignment. Here are some common problems:
Open Bite
An open bite occurs when upper and lower front teeth don’t touch when the mouth is closed. This gap happens because the pacifier pushes the front teeth forward continuously. It can affect speech development and chewing efficiency.
Crossbite
A crossbite means one or more upper teeth bite inside the lower teeth instead of outside. Prolonged sucking habits can cause narrowing of the upper jaw, leading to this misalignment.
Overjet
Overjet describes upper front teeth that protrude significantly over lower teeth, often called “buck teeth.” Extended pacifier use encourages this forward movement.
Changes in Palate Shape
Constant pressure from sucking can alter the shape of the roof of the mouth (palate), making it narrower or higher than normal. This may cause crowding of permanent teeth later on.
The Role of Duration and Intensity in Dental Effects
Not all pacifier use damages teeth equally. The risk increases with how long and how forcefully children suck on them.
Children who use pacifiers only occasionally or for short naps usually avoid serious dental issues. On the other hand, those who suck vigorously for hours daily face a higher chance of developing malocclusion (misaligned bite).
Experts suggest limiting pacifier use by:
- Avoiding use beyond 12-18 months.
- Encouraging weaning off between ages 2-4.
- Restricting usage to sleep times only.
- Selecting orthodontic pacifiers designed to minimize dental impact.
These guidelines help reduce pressure on developing teeth and jaws while still providing comfort when needed.
Comparing Pacifier Use With Thumb Sucking
Thumb sucking is another common habit that affects dental health similarly to pacifier use but differs in some ways.
Unlike a pacifier, which parents can control or limit easily, thumb sucking is harder to manage since children have constant access to their thumbs. Both habits exert similar forces on the mouth structures but thumb sucking tends to be more forceful because children can apply stronger suction with their thumbs.
Studies show that prolonged thumb sucking beyond age four has similar risks for causing open bites, crossbites, and palate changes as extended pacifier use.
Parents often ask which habit is worse for teeth: thumb sucking or pacifiers? Orthodontists usually agree that controlled pacifier use is preferable since it’s easier to stop and less damaging if managed properly.
The Impact of Orthodontic Pacifiers Versus Traditional Ones
Not all pacifiers are created equal when it comes to dental health. Orthodontic pacifiers have been designed with shapes intended to reduce pressure on developing gums and teeth.
These typically feature:
- A flattened bottom surface mimicking natural nipple shape.
- A thinner nipple tip that encourages proper tongue placement.
- A curved shield allowing better airflow around the mouth.
Research suggests orthodontic pacifiers may lessen but not completely eliminate risks associated with prolonged use. They still should be used sparingly and phased out at an appropriate age.
Traditional round-shaped nipples tend to push against front teeth more aggressively, increasing chances for misalignment problems.
The Timeline: When Does Pacifier Use Start Affecting Teeth?
The timing of dental effects depends largely on how long children keep using their pacifiers as they grow.
Here’s what happens at different stages:
- Infancy (0-12 months): Minimal risk; baby teeth are just starting to develop below gums.
- Toddler years (1-3 years): Baby teeth erupt; prolonged sucking starts influencing tooth positioning.
- Preschool years (3-5 years): Jaw growth accelerates; continued sucking habits may cause noticeable malocclusion.
- After age 5: Permanent teeth begin erupting; ongoing habits can lead to lasting orthodontic issues needing correction.
This timeline highlights why pediatric dentists recommend weaning from pacifiers by around age two or three at latest—to prevent long-term damage.
The Link Between Pacifiers and Speech Development
Besides dental alignment concerns, extended pacifier use may also affect speech development in young children.
Continuous presence of a foreign object in the mouth limits tongue movement necessary for forming sounds correctly. Children who rely heavily on pacifiers might experience delayed articulation or difficulty pronouncing certain consonants like “s,” “t,” or “l.”
Speech therapists often recommend reducing or eliminating pacifier use before speech milestones become critical—usually by age two—to encourage normal oral motor skills development.
Dental Care Tips for Children Using Pacifiers
If your child uses a pacifier regularly, these practical tips help safeguard their oral health:
- Clean Pacifiers Daily: Wash them thoroughly with warm soapy water or sterilize regularly to prevent bacteria buildup.
- Avoid Dipping in Sugary Substances: Never dip a pacifier in honey or sugar—this promotes tooth decay.
- Monitor Usage Time: Limit usage mainly during naps or bedtime rather than all day long.
- Select Orthodontic Designs: Choose products labeled “orthodontic” for gentler impact on gums and teeth.
- Schedule Early Dental Visits: Start regular pediatric dentist checkups by first birthday for early monitoring.
Consistent care combined with timely weaning helps minimize potential harm from necessary soothing tools like pacifiers.

Frequently Asked Questions
Do pacifiers affect teeth if used only occasionally?
Occasional pacifier use in early infancy generally does not harm teeth. The American Dental Association states that limited use is unlikely to cause dental problems, especially if stopped before permanent teeth begin to develop.
How do pacifiers affect teeth alignment in toddlers?
Prolonged pacifier use can push developing teeth out of alignment. This pressure may cause issues like open bite, crossbite, or overjet, especially if the habit continues beyond age two to four when permanent teeth start forming.
Can pacifiers cause changes in the shape of the mouth affecting teeth?
Yes, constant sucking on a pacifier can alter the palate’s shape, making it narrower or higher. These changes may lead to crowding and misalignment of permanent teeth as a child grows.
At what age do pacifiers begin to affect teeth negatively?
Dental problems are more likely if pacifier use continues past two or three years old. By this age, permanent teeth start developing, and extended sucking habits can interfere with their proper eruption and positioning.
What types of dental issues are linked to pacifier use affecting teeth?
Common dental problems caused by prolonged pacifier use include open bite, crossbite, and overjet. These conditions result from pressure on teeth and jaws that disrupt normal growth and alignment.
Pediatric Dentist Recommendations Regarding Pacifiers
Most pediatric dentists agree that short-term use of a pacifier during infancy offers soothing benefits without major harm. However, they emphasize:
- The importance of limiting duration beyond toddlerhood.
- The need for parental guidance during weaning phases between ages two and four.
- The value of orthodontic designs over traditional models where possible.
- The necessity for regular oral exams starting early in life .
- The avoidance of sugary coatings on nipples .
- The promotion of alternative comfort methods once weaned .
Following these recommendations balances emotional comfort with healthy oral development — no mean feat for busy families!
