Understanding Hutchinson-Gilford Progeria Syndrome (HGPS)
Hutchinson-Gilford Progeria Syndrome (HGPS) is an extremely rare, fatal genetic disorder characterized by striking features of premature aging in children. Caused by a mutation in the LMNA gene, HGPS affects many body systems, including cardiovascular health, musculoskeletal structure, and, notably, dental development. While many aspects of normal childhood development are profoundly altered, the question of oral health, and whether people with progeria have teeth, is a specific area of concern for families and caregivers.
The Impact of HGPS on Dental Development
The effects of HGPS on dental health are significant and begin early in life. Unlike most children who start teething around six months of age, those with progeria experience a considerable delay. This is often just the first of many dental challenges they face due to the underlying genetic condition affecting growth and development.
Key Dental Characteristics in Progeria
- Delayed Eruption: Both primary (baby) and permanent teeth emerge much later than in typically developing children. In many cases, permanent teeth may not erupt at all.
- Dental Crowding: Due to an underdeveloped jaw (micrognathia), children with progeria often have insufficient space for their teeth. This leads to severe crowding, malocclusion (poor bite), and ectopic eruption, where teeth emerge in abnormal positions.
- Agenesis of Teeth: Agenesis, or the congenital absence of some permanent teeth, is a common finding in HGPS, particularly affecting second premolars. This further complicates alignment and function.
- High Caries Incidence: Individuals with progeria have a high rate of tooth decay and cavities, possibly due to changes in oral mucosa and reduced salivary flow, which makes maintaining oral hygiene more difficult.
- Periodontal Disease: Gingivitis (gum inflammation) and progressive periodontal disease are frequent issues, exacerbated by crowding and systemic effects of the syndrome.
- Tooth Attrition: The primary teeth of children with HGPS may experience significant wear and tear (attrition).
- Abnormal Tooth Structure: Some studies note thin, impaired dentin, which can make teeth more fragile and sensitive.
The Role of Early and Specialized Dental Care
Because of these pervasive dental issues, establishing a relationship with a pediatric dentist early in a child's life is crucial for those with HGPS. The American Dental Association recommends a first dental visit by age one, or when the first tooth appears, which is a key milestone for preventative care in progeria.
Preventative Care and Management
Early dental intervention for a child with progeria includes:
- Frequent Check-ups: Biannual or more frequent visits allow the dentist to monitor oral development, manage emerging issues, and provide timely interventions.
- Fluoride Treatments: Regular application of fluoride is essential to combat the high risk of cavities. This can include in-office treatments, gels, or rinses.
- Oral Hygiene Education: Parents and caregivers need ongoing support and instruction on how to maintain the best possible oral hygiene at home, given the unique challenges of a small jaw and crowded teeth.
Comparison of Dental Development: HGPS vs. Typical Development
| Characteristic | Typical Dental Development | HGPS Dental Development |
|---|---|---|
| Primary Teeth Eruption | Begins around 6 months old; complete by age 3 | Significantly delayed; often incomplete |
| Permanent Teeth Eruption | Begins around age 6; complete by early teens | Delayed and often incomplete; some teeth may never erupt |
| Tooth Alignment | Natural spacing allows for proper alignment | Severe crowding and malocclusion due to underdeveloped jaw |
| Missing Teeth (Agenesis) | Very uncommon; usually occurs with certain syndromes | Hypodontia is common, especially with permanent premolars |
| Cavity Risk | Varies; manageable with good hygiene | High incidence due to oral mucosa changes and other factors |
| Jaw Development | Normal jaw growth accommodates teeth | Micrognathia (small jaw) results in insufficient space |
The Broader Implications of Oral Health in Progeria
Beyond the functional issues of chewing and speech, poor oral health in HGPS has systemic consequences. Infections and inflammation, such as gingivitis and periodontal disease, can have an impact on a person's overall health. Managing these conditions is part of the comprehensive care required for individuals with this complex syndrome.
The Future of Dental Management
Orthodontic therapy may be considered in some cases to address crowding and malocclusion, although the specific needs of each patient and the presence of underlying conditions require a specialized approach. Close collaboration with oral surgeons may also be necessary for the strategic removal of retained primary teeth to make way for permanent dentition.
With ongoing research and supportive care, dental management strategies continue to improve, helping to enhance the quality of life for children with progeria. The Progeria Research Foundation provides invaluable resources and guidelines for both families and healthcare professionals to navigate these challenges effectively.

Conclusion: More Than Just a Yes or No
The question, "do people with progeria have teeth?" reveals a far more intricate picture than a simple affirmative or negative answer can provide. While teeth do develop, the process is fraught with significant delays and complications, including micrognathia, crowding, and a high risk of decay. Effective management requires early, consistent, and specialized dental care to mitigate these challenges and support the overall health and well-being of those living with HGPS.
