The Double Row Dilemma: Understanding “Shark Teeth” and “Double Teeth in Kids” and the Importance of Early Intervention
What are “double teeth” in kids?
Witnessing a new adult tooth emerge behind a seemingly steadfast baby tooth can be a perplexing sight for parents. This phenomenon, often referred to as “shark teeth” or what some parents describe as “double row of teeth in kids”, is a relatively common occurrence in children dentistry. While it might appear alarming, understanding the underlying mechanisms, potential long-term consequences, and the benefit of timely intervention is crucial for ensuring a child’s healthy dental development.
Shark Teeth: This is when permanent adult teeth erupt behind baby teeth that haven’t yet fallen out, creating a double row. This is common, especially with the lower front teeth around age 6-7.
Fused or Geminated Teeth: This is a dental anomaly where two developing tooth buds join together (fusion) or a single tooth bud tries to split into two (gemination), resulting in a tooth that appears wider than normal. This is less common.
What causes double teeth?
Witnessing a new adult tooth emerge behind a seemingly steadfast baby tooth can be a perplexing sight for parents. This phenomenon, often referred to as “shark teeth” or what some parents describe as “double row of teeth in kids”, is a relatively common occurrence in children dentistry. While it might appear alarming, understanding the underlying mechanisms, potential long-term consequences, and the benefit of timely intervention is crucial for ensuring a child’s healthy dental development.
Normally, the eruption of permanent teeth is a carefully orchestrated process. As the adult tooth develops beneath the gum line, specialized cells called osteoclasts are activated. These cells are responsible for the physiological resorption of the roots of the overlying baby tooth. This root resorption is a gradual process, leading to the baby tooth becoming loose and eventually shedding, paving the way for its permanent successor to erupt into the correct position.
However, in some instances, this resorption process may not occur as expected, or the permanent tooth might erupt slightly off its intended path. This can result in the permanent tooth emerging behind the still-firmly attached baby tooth, creating the visual effect of “double teeth in kids” or “shark teeth”. Several factors can contribute to this situation. Genetic predisposition can play a role, influencing the timing and pattern of tooth eruption. Additionally, the angulation of the erupting permanent tooth or a lack of sufficient space in the jaw can cause it to deviate from the typical eruption pathway. In some cases, trauma to the baby tooth can also affect the resorption of its root.
According to the Australian Dental Association (ADA), the prevalence of retained primary teeth varies depending on the specific tooth. While any primary tooth can be retained, some are more commonly affected than others. For instance, upper second molars and upper canines are frequently cited as teeth that may be retained beyond their expected exfoliation time.
However, the phenomenon of adult teeth erupting behind baby teeth, leading to the appearance of “shark teeth” or “double teeth in kids”, is often most noticeable in the incisor region, particularly the lower incisors, due to their prominent position in the mouth. Studies have shown that the incidence of retained primary incisors with erupting permanent successors can range from 1% to 10% in children, making “double teeth in kids” a relatively frequent concern for parents.
