Gaten Matarazzo, best known for playing the beloved character Dustin Henderson on Netflix’s hit sci-fi series Stranger Things, has become known for his infectious smile that is missing his two front teeth. So why has the actor been without his front chompers since childhood? The reason has to do with a rare genetic disorder he was born with.

Understanding Cleidocranial Dysplasia

Understanding Cleidocranial Dysplasia

Gaten was born with a condition called cleidocranial dysplasia (CCD). This is a genetic disorder that primarily affects the development of bones and teeth. CCD is caused by a mutation in the RUNX2 gene and is inherited in an autosomal dominant pattern. Some of the key signs and symptoms include:

Underdeveloped or Absent Collarbones

One of the hallmarks of CCD is collarbones (clavicles) that are partially formed or completely absent. The shoulders can therefore get very close together or even touch in the front of the body. This allows those with CCD to perform tricks like bringing their shoulders together.

Delayed Loss of Deciduous (Baby) Teeth

CCD often causes a delay in shedding primary/deciduous teeth. This means baby teeth can remain in place for longer than normal. This can result in a very crowded mouth because the permanent teeth still try to erupt on the typical schedule.

Failure of Permanent Teeth to Erupt Properly

Frequently, permanent adult teeth become impacted or unable to fully emerge in the mouth due to obstruction or lack of space. The teeth may become stuck under the gums. This is why Gaten has been missing his two upper front teeth since childhood.

Conductive Hearing Loss

Hearing problems are common with CCD, typically a conductive hearing loss from middle ear issues. The smaller bones of the middle ear can be underdeveloped or malformed. Gaten had ear tubes inserted when he was younger to deal with hearing impairment.

Short Stature

In severe cases of CCD, some individuals can have very short stature as adults due to problems with long bone growth. However, most people with CCD are within the average height range, including Gaten Matarazzo.

Dental Issues

Dental anomalies like delayed tooth eruption, crowding, misalignment and high risk for cavities are extremely common. Gaten has required extensive orthodontic work and dental procedures to manage these symptoms.

So in summary, cleidocranial dysplasia is a complex genetic condition affecting bone and dental development in many areas of the body. The most visible signs are clavicle abnormalities, retention of baby teeth and lack of permanent tooth eruption.

Gaten’s Diagnosis and Treatment Journey

Gaten Matarazzo was diagnosed with CCD at a young age after his parents noticed some of the classic features of the disorder emerging:

  • Extremely flexible collarbone that allowed him to bring his shoulders together
  • An underbite caused by delayed loss of primary teeth
  • X-rays that showed adult teeth trapped under the gums

The family sought evaluations from geneticists and dental specialists. Genetic testing confirmed the diagnosis of CCD by identifying a pathogenic variant in Gaten’s RUNX2 gene.

Living with CCD requires lifelong dental care and orthodontic treatment. Here are some of the key procedures Gaten has undergone so far:

  • Tooth extraction surgery to remove baby teeth or painful primary teeth obstructing the path of eruption
  • Dental implant placement for a permanent tooth that was congenitally missing
  • Exposure surgery to pull permanent teeth down through the gums
  • Spacers and expanders to create room in his crowded mouth
  • Ongoing orthodontics using braces and alignment techniques

Despite significant dental work, Gaten is still missing his two permanent maxillary central incisors. These upper front teeth likely became fused or impacted and could not fully erupt. Future dental implants are a possibility, but Gaten has embraced his natural smile for now.

Effects of CCD on Daily Life

Effects of CCD on Daily Life

CCD affects individuals differently depending on the variations in symptoms and severity. For Gaten Matarazzo, the impacts have included:

  • Self-confidence issues – The condition resulted in bullying when he was young due to looking different from other kids. He eventually learned to embrace his uniqueness.
  • Social limitations – Those with CCD may avoid smiling or feel embarrassed about their teeth. Gaten has become an inspirational role model for self-acceptance.
  • Dental care routines – Practicing excellent oral hygiene and having frequent dental visits is a must to prevent tooth decay or loss of additional teeth over time.
  • Hearing aids – Conductive hearing loss is common with CCD due to the malformed bones. Gaten had ear tubes as a child but does not require hearing aids currently.
  • Normal physical development – Despite dental and skeletal symptoms, overall growth is usually unaffected. Gaten reached average adult height and has no major mobility issues.
  • Variable expressivity – There is a broad spectrum of possible effects with CCD. Gaten’s case is considered moderate compared to more severe cases.
