Preemies typically begin teething between 4 to 12 months adjusted age, but timing varies widely due to their early birth.
Understanding Teething in Preemies
Teething marks a significant milestone in any infant’s development, signaling the arrival of their first teeth. For babies born prematurely—before 37 weeks of gestation—the timeline for teething can be quite different from full-term infants. The question “When Do Preemies Start Teething?” is common among concerned parents and caregivers eager to understand what to expect.
Premature infants often face a unique set of developmental challenges because their bodies and systems are still maturing outside the womb. This immaturity affects various aspects of growth, including dental development. Unlike full-term babies who usually start teething around 6 months of age, preemies’ teeth may erupt later or follow an adjusted schedule based on their corrected age (calculated from their due date rather than birth date).
It’s important to note that prematurity doesn’t necessarily mean delayed teething for every baby. Some preemies may begin teething earlier or right on schedule with their peers when accounting for corrected age. However, many experience delays or irregular patterns influenced by factors such as medical complications, nutrition, and overall growth rates.
Factors Influencing Teething Timing in Premature Babies
A variety of factors influence when preterm infants start teething. These include:
Corrected Age vs. Chronological Age
One critical concept is the difference between chronological age (actual age since birth) and corrected age (age adjusted for prematurity). For example, a baby born 8 weeks early who is now 6 months old chronologically would have a corrected age of about 4 months. Dentists and pediatricians often use corrected age to assess developmental milestones like teething.
Medical Conditions and Complications
Premature babies are at higher risk for health issues such as respiratory distress syndrome, feeding difficulties, or infections that can affect overall growth and development. Chronic illness or extended hospital stays may delay the eruption of teeth because the body prioritizes essential survival functions over secondary milestones like dental growth.
Nutrition and Feeding Methods
Proper nutrition is crucial for healthy tooth development. Many preemies initially rely on tube feeding or specialized formulas that may differ in mineral content compared to breastfeeding or standard infant formulas. Calcium, phosphorus, vitamin D, and other nutrients directly impact tooth mineralization and eruption timing.
Genetic Factors
Family history plays a role too. If parents experienced delayed teething themselves, premature infants might follow similar patterns regardless of gestational age at birth.
The Typical Timeline: When Do Preemies Start Teething?
While individual cases vary widely, research and clinical observations provide some general timelines:
- Full-term infants: First teeth usually emerge between 4-7 months.
- Preterm infants (adjusted age): Teeth commonly appear between 4-12 months corrected age.
- Delayed eruption: Some preemies might not show any signs until after their first birthday when measured chronologically.
The wide range reflects how each baby’s unique health profile influences dental milestones.
Signs That Indicate Teething Has Begun
Parents often look for clues signaling that teeth are on their way:
- Increased drooling
- Irritability or fussiness
- Sore or swollen gums
- A tendency to chew on objects
- Slight changes in sleep patterns
These signs might appear weeks before a tooth actually breaks through the gum line.
The Science Behind Premature Tooth Eruption Delays
Tooth development begins in utero around the sixth week of pregnancy with the formation of tooth buds. By about the fourth month gestation, mineralization starts for primary teeth enamel and dentin layers.
Premature birth interrupts this carefully timed process as babies exit the protective environment before full dental maturation occurs. This interruption can slow enamel calcification and root formation—critical steps before teeth erupt properly.
Moreover, systemic illnesses common in NICU stays can affect calcium metabolism or delay general growth signals responsible for initiating tooth eruption sequences.
The Role of Dental Care for Preemies During Early Development
Good oral health practices should begin even before the first tooth appears. For premature infants:
- Mouth care: Gently cleaning gums with a soft cloth helps reduce bacteria buildup.
- Pediatric dental visits: The American Academy of Pediatric Dentistry recommends a first dental checkup by one year adjusted age or within six months after the first tooth erupts.
- Nutritional counseling: Ensuring adequate intake of calcium and vitamin D supports healthy teeth formation.
- Avoiding harmful habits: Limiting prolonged bottle feeding and sugary liquids reduces risk for early decay once teeth appear.
Early intervention can prevent complications like enamel hypoplasia—a condition where enamel is thin or underdeveloped—more common in preterm infants.
A Closer Look: Comparing Teething Milestones Between Preemies and Full-Term Infants
| Milestone | Full-Term Infants (Chronological Age) | Preterm Infants (Corrected Age) |
|---|---|---|
| First Tooth Eruption (Central Incisors) | 4-7 months | 4-12 months* |
| Total Primary Teeth by Age 1 Year | 6-8 teeth average | Variable; often fewer than full-term peers* |
| Pediatric Dental Visit Recommended By | By 1 year chronological age or within 6 months after first tooth erupts | By 1 year corrected age or within 6 months after first tooth erupts* |
| Nutritional Needs Impacting Teeth Development | Adequate breastfeeding/formula feeding with minerals & vitamins support timely eruption. | Nutritional supplementation often needed; close monitoring required.* |
| *Depends heavily on individual health status and medical history. | ||
This table highlights how adjusting expectations based on corrected age helps caregivers track progress realistically.
Troubleshooting Delayed Teething: When Should You Worry?
Delayed tooth eruption alone isn’t always cause for alarm in preemies due to their unique developmental path. However, certain signs warrant professional evaluation:
- No signs of any teeth by 18 months corrected age.
- Persistent gum swelling without tooth breakthrough beyond expected timeframes.
- Poor overall growth combined with delayed milestones across other domains.
- Evident enamel defects once teeth appear that could indicate underlying metabolic issues.
Pediatric dentists can perform examinations including X-rays if needed to assess underlying jawbone development or detect missing teeth (congenital absence).
Early identification allows tailored interventions such as nutritional adjustments or specialized oral care plans.
Caring Tips for Soothing Preemie Teething Discomforts Safely
Teething discomfort affects babies regardless of term status but premature infants may be more sensitive due to fragile health conditions. Safe soothing techniques include:
- Cooled teething rings: Offer gentle relief without risk of choking.
- Mild gum massages: Using clean fingers can ease soreness.
- Avoiding medication overuse: Consult pediatricians before giving any pain relief drugs; dosages vary especially in medically fragile infants.
- Keeps toys clean: Prevent infections by sterilizing items frequently mouthed during teething phases.
Being attentive while providing comfort helps reduce stress for both baby and caregivers during this challenging period.
The Link Between Prematurity and Long-Term Dental Health Risks
Research indicates that premature birth not only affects initial eruption timing but also long-term oral health outcomes:
- Enamel hypoplasia: Thinner enamel increases susceptibility to cavities early on.
- Misaligned teeth: Jaw development differences may cause orthodontic concerns later.
- Xerostomia risks: Some preemies experience dry mouth due to medications impacting saliva production—saliva protects against decay.
Ongoing dental monitoring throughout childhood ensures timely interventions minimizing lasting damage.

Frequently Asked Questions
When Do Preemies Start Teething Compared to Full-Term Babies?
Preemies typically start teething between 4 to 12 months adjusted age, which accounts for their early birth. This means their teething timeline is often delayed compared to full-term babies who usually begin around 6 months chronological age.
When Do Preemies Start Teething Considering Corrected Age?
Corrected age is used to assess developmental milestones in preemies. A baby born early might start teething according to their corrected age rather than chronological age, which helps explain why some preemies begin teething later than expected.
When Do Preemies Start Teething if They Have Medical Complications?
Medical complications common in preemies, such as respiratory issues or infections, can delay teething. The body focuses on critical survival functions first, so tooth eruption may occur later if health problems affect overall growth.
When Do Preemies Start Teething and How Does Nutrition Affect It?
Nutrition plays a vital role in dental development for preemies. Specialized feeding methods or formulas may influence the timing of teething, as adequate nutrients are essential for healthy tooth eruption and growth.
When Do Preemies Start Teething and Is Early Teething Possible?
While many preemies experience delayed teething, some may begin earlier or on schedule when corrected age is considered. Each infant’s development varies, so early teething in preterm babies is possible but less common.
Conclusion – When Do Preemies Start Teething?
When Do Preemies Start Teething? The answer isn’t cut-and-dry but generally falls between 4 to 12 months adjusted age depending on individual circumstances. Prematurity shifts typical timelines because early birth interrupts natural dental maturation processes alongside other developmental pathways.
Understanding this nuanced timeline helps caregivers set realistic expectations while providing attentive care tailored to each baby’s needs.
