Late teething in children is defined as no teeth appearing by 13 months of age, and it warrants a paediatric dental assessment rather than a wait-and-see approach. The American Academy of Pediatric Dentistry (AAPD) recommends consulting a paediatric dentist if no teeth have erupted by 18 months, but early assessment from 13 months gives more time to identify and address any underlying cause before consequences develop. In most cases, late teething is caused by genetics and is harmless. In a smaller number of cases it signals a nutritional deficiency, hormonal imbalance, or a developmental condition that benefits significantly from early identification. The consequences of late teething, when they do occur, fall into four categories: oral development, nutrition, speech, and systemic health.

1. Potential Impact on Oral Development
Late teething may disrupt the natural sequence of tooth eruption, which can lead to alignment issues. Baby teeth act as placeholders for permanent teeth, guiding them into proper positions. If baby teeth erupt late or in an unusual order, it can increase the risk of crowding, misalignment, or impaction of adult teeth.
2. Delayed Ability to Chew and Eat Properly
Primary (baby) teeth are essential for chewing and biting, which play a role in introducing a child to a variety of foods and textures. Delayed teething can restrict a child’s ability to eat solid foods, potentially affecting their nutrition and overall growth. The AAPD recommends dietary monitoring for children with late teething to ensure proper nutrient intake.
3. Speech and Language Development Challenges
Teeth, particularly the front incisors, contribute to proper pronunciation and speech development. Late teething can delay the acquisition of certain sounds and speech patterns. If parents notice speech delays, it’s important to consult a pediatric dentist for early intervention.
4. Underlying Medical Conditions
In some cases, late teething could signal underlying medical or genetic conditions. These may include:
- Nutritional Deficiencies: Lack of calcium, vitamin D, or other nutrients can affect tooth development.
- Endocrine Disorders: Hypothyroidism or other hormonal imbalances may delay teething.
- Genetic Disorders: Conditions such as Down syndrome or ectodermal dysplasia can slow the teething process.
Regular dental check-ups with your child’s pediatric dentist will help rule out these potential issues and address them promptly.

When to Seek Professional Advice
While some variation in teething is normal, the AAPD advises consulting a pediatric dentist if:
- No teeth have erupted by 18 months of age.
- Teething is accompanied by signs of systemic issues, such as poor growth or developmental delays.
- There are significant concerns about speech or chewing abilities.

Friendly Asked Questions
Late teething is generally defined as no teeth erupting by 13 months of age. The American Academy of Pediatric Dentistry recommends a paediatric dental assessment if no teeth have appeared by 18 months. Most babies begin teething between 6 and 12 months, with the lower central incisors typically appearing first.

Late teething can affect oral development by disrupting the normal tooth eruption sequence, increasing the risk of crowding and misalignment of permanent teeth. It can delay the ability to chew solid foods properly, potentially affecting nutrition and growth. It may also slow the development of certain speech sounds, particularly those requiring front teeth such as "f", "v", "th", and "s". In some cases it signals an underlying medical condition that benefits from early diagnosis and treatment.
Yes. Front teeth, particularly the upper central incisors, play an important role in forming certain speech sounds. Children who are late to develop these teeth may take longer to produce sounds that depend on the tongue contacting the upper teeth. If a speech delay is noticed alongside late teething, a paediatric dentist and a speech therapist should both be consulted.
It can. Baby teeth act as space holders that guide permanent teeth into their correct positions. When baby teeth erupt late or in an unusual sequence, the spacing and guidance function they provide is delayed, which can increase the risk of crowding, impaction, or misalignment of the permanent teeth that follow. Early orthodontic assessment is recommended for children with a significantly delayed teething pattern.
Consult a paediatric dentist if no teeth have appeared by 13 to 15 months, or sooner if you have concerns. The AAPD recommends a dental visit by the first birthday regardless of how many teeth have appeared, which means late teething can be monitored from a very early stage. At Harmony Medical Centers in Dubai and Abu Dhabi, our specialist paediatric dentists assess teething timelines, take X-rays where needed to confirm tooth development, and advise parents on what to watch for and when to intervene.
Yes. Significant variation in teething timing is normal and the majority of late teethers have no underlying health issue. A child who begins teething at 12 to 14 months rather than 6 months is within the range of normal variation. The concern arises when no teeth appear by 18 months, when the delay is accompanied by other developmental concerns, or when X-rays confirm absence of developing tooth buds.
Yes. Vitamin D and calcium are essential for tooth mineralisation and development. Deficiency in either can delay teething. Vitamin D deficiency in particular is common in the UAE and globally, and is a routinely checked cause of delayed tooth eruption in paediatric dental practice. If late teething is identified, your child's paediatrician may check vitamin D levels as part of the assessment.
