How Pacifier Use May Affect Developing Teeth and Jaws
Pacifiers can be a helpful tool for soothing babies, calming them during stressful moments, and satisfying their natural need to suck. For many parents, a pacifier becomes part of a baby’s daily routine. But as teeth and jaws begin to develop, parents may wonder whether the type of pacifier they choose could affect their child’s oral health. If you have questions about your baby’s pacifier use or developing smile, Aesthetic Dental Associates is here to help families in Seattle. To speak with Dr. Robert E. Johnson about your child’s dental development, call (206) 682-3888.
The good news is that using a pacifier does not automatically mean a child will develop dental problems. The bigger concerns are often how frequently a child uses a pacifier, how long the habit continues, and whether it becomes a prolonged sucking habit.
Different pacifiers also have different shapes, materials, and designs. Understanding the potential pros and cons can help parents make informed choices while keeping developing teeth and jaws in mind.
How Can Pacifiers Affect Dental Development?
Baby teeth begin developing before they appear in the mouth, and the jaw and surrounding oral structures continue changing throughout childhood. Repeated sucking can place pressure on these developing structures.
Occasional pacifier use during infancy is generally less concerning than a habit that continues for several hours every day or persists well into the toddler years. Prolonged sucking may contribute to changes in the way the upper and lower teeth come together.
Potential dental effects associated with persistent sucking habits can include:
- Anterior open bite, where the upper and lower front teeth do not meet
- Posterior crossbite, where some upper teeth bite inside the lower teeth
- Changes in the position or angle of developing teeth
- Changes in the shape of the dental arches
- Alterations in normal oral muscle patterns
These effects are not guaranteed to occur in every child who uses a pacifier. A child’s genetics, oral development, sucking intensity, frequency of use, and age all play a role.
For this reason, choosing a pacifier based solely on its shape is not enough. Parents should also consider how and when the pacifier is being used.
1. Traditional Round-Tip Pacifiers
Traditional round-tip pacifiers have a rounded nipple that resembles the shape of a bottle nipple or the breast during nursing. They are one of the most familiar pacifier designs and are widely available.
Pros
- Simple, familiar design
- Available in many sizes and materials
- May be readily accepted by some babies
- Satisfies the natural sucking reflex
- Easy to find and replace
From a dental perspective, there is no need to assume that a traditional round pacifier will automatically cause dental problems. Occasional use during infancy is different from frequent, prolonged sucking throughout the day.
Cons
The primary concern is repeated pressure on developing teeth and oral structures. If a child frequently sucks on a pacifier for long periods, the habit may contribute to changes in tooth position or bite development.
The rounded nipple may also occupy more space between the upper and lower teeth than some flatter designs. However, the shape of the pacifier is only one factor. A child who uses a round-tip pacifier briefly for soothing has a different level of exposure than a child who keeps one in their mouth for much of the day.
2. Orthodontic Pacifiers
Orthodontic pacifiers have a nipple that is typically flatter on one side and designed to accommodate the tongue and palate. They are marketed with oral development in mind.
Pros
- Designed around the shape of the developing mouth
- Flattened nipple may distribute contact differently within the mouth
- May feel comfortable for some babies
- Available in a variety of sizes and materials
Some parents choose orthodontic pacifiers because they are concerned about the potential effect of traditional pacifiers on developing teeth.
Cons
The word “orthodontic” does not mean a pacifier is incapable of affecting dental development. Continued sucking can still place pressure on teeth and surrounding oral structures regardless of the nipple design.
Parents should also be cautious about assuming that an orthodontic pacifier will prevent future orthodontic problems. No pacifier design completely eliminates the potential effects of a prolonged sucking habit.
3. Silicone One-Piece Pacifiers
One-piece silicone pacifiers are made from a single piece of silicone rather than several assembled components. They are popular with parents who want a simple design that can be cleaned easily.
Pros
- Smooth silicone surface
- Simple construction
- Easy to clean
- No separate nipple and shield pieces
- Consistent shape
- Available in different sizes and designs
Good hygiene is important because pacifiers regularly come into contact with a baby’s mouth. A design that is easy to clean can make it easier for parents to maintain appropriate hygiene.
Cons
The one-piece construction does not eliminate the dental concerns associated with prolonged sucking. The nipple still sits against the developing teeth, gums, tongue, and palate.
Parents should also avoid assuming that silicone itself makes a pacifier better for developing teeth. The material can affect the feel and firmness of the nipple, but it does not prevent bite changes caused by a persistent sucking habit.
4. Natural Rubber Pacifiers
Natural rubber pacifiers are made from latex or natural rubber and are often softer and more flexible than silicone designs. Some babies prefer the texture and feel of rubber.
Pros
- Soft, flexible nipple
- May feel comfortable to some babies
- Can provide a familiar sucking sensation
- Available in several shapes and sizes
A softer nipple may be appealing to an infant, particularly when the pacifier is being used for occasional soothing.
Cons
Softness does not prevent the potential dental effects of prolonged pacifier use. Repeated sucking can still place pressure on developing teeth and oral structures.
Natural rubber can also change over time. The material may become sticky, cracked, swollen, or otherwise damaged with use. A worn pacifier may no longer have the same shape or texture it had when new.
Parents should inspect rubber pacifiers regularly and replace them according to the manufacturer’s recommendations or sooner if they show signs of deterioration.
5. Flat or Symmetrical Pacifiers
Flat or symmetrical pacifiers have a nipple designed to sit in the mouth without requiring a specific top-to-bottom orientation. Their shape may be flatter than a traditional round-tip pacifier.
Pros
- Can be placed in the mouth in either direction
- Flat profile may take up less space in the mouth
- Some babies find the shape comfortable
- Available in silicone and other materials
- Convenient for parents and caregivers
The symmetrical design can make these pacifiers easier to use, especially when a baby frequently removes and replaces the pacifier.
Cons
A flatter shape does not eliminate the effects of prolonged sucking. Even when a pacifier is designed to reduce bulk in the mouth, frequent sucking can still influence developing teeth and bite relationships.
Parents should also be careful about claims that a particular pacifier shape guarantees healthy oral development. Dental development is influenced by many factors, and no pacifier can eliminate the effects of a persistent sucking habit.
Which Pacifier Is Best for Your Baby’s Teeth?
There is no single pacifier that can guarantee ideal dental development. Traditional, orthodontic, silicone, rubber, flat, and symmetrical pacifiers all have different features, but the way a child uses the pacifier may be more important than the label on the package.
When choosing a pacifier, parents can consider:
- The child’s age and developmental stage
- Nipple shape and size
- Material
- Ease of cleaning
- Condition and durability
- How frequently the child uses it
- Whether the pacifier is becoming a constant comfort habit
Parents should also choose a pacifier that is appropriately sized for their child’s age and follow the manufacturer’s safety instructions.
Most importantly from a dental perspective, try to avoid allowing the pacifier to become something your child uses continuously throughout the day.
Have Questions About Your Child’s Pacifier Habit?

Johnson can evaluate your child’s oral development, answer your questions, and provide personalized guidance for your family in Seattle. Call (206) 682-3888 to schedule a visit.
Choosing a Pacifier With Dental Health in Mind
Pacifiers can serve an important purpose during infancy, and parents do not need to feel guilty about using one to soothe their baby. From a dental perspective, however, it is important to think beyond the pacifier’s shape or brand.
Frequency and duration of use are key considerations. As your child grows, gradually reducing pacifier use can help minimize the potential effects of prolonged sucking on developing teeth and jaws.
If you have questions about your child’s pacifier habit, tooth development, or bite, Aesthetic Dental Associates is here to help. Aesthetic Dental Associates can provide personalized guidance and monitor your child’s developing smile during dental visits in Seattle.
