A V-shaped smile can result from several factors, including genetics and lifestyle choices. Your natural tooth alignment, jaw structure, and even the way your gums are positioned play a role in how your smile appears.
Genetic Factors
- Inherent Tooth Alignment: Some individuals are naturally born with teeth that create a V-shape when they smile. This is a matter of genetic predisposition and natural tooth development. The references cite examples of children having crooked or V-shaped teeth as they emerge, showing a clear genetic influence. (Teeth coming in crooked (v shaped) - January 2018 Babies | Forums ...)
Lifestyle Factors and External Influences
- Jaw Deterioration: Lifestyle factors such as smoking can contribute to jaw deterioration, which might subtly influence the shape of your smile. ([These can be caused by genetics or lifestyle factors...](Reference Text))
- Gingivitis: Gum disease (gingivitis) can also lead to uneven gums, potentially altering the visual appearance of your smile and creating a more pronounced V-shape. ([These can be caused by genetics or lifestyle factors...](Reference Text))
- Orthodontic Treatments: Conversely, orthodontic treatments like Invisalign or braces can change the shape of your smile. While often aiming to straighten teeth, they can also subtly affect the overall shape of your smile. Jaw expanders, for instance, are mentioned in the references as potentially widening the jaw and altering the previously V-shaped smile.

- Missing Teeth: The absence of adult teeth can create a V-shape, a feature which can be addressed by dental implants or other restorative procedures. ([These can be caused by genetics or lifestyle factors...](Reference Text))
Determining the precise cause of your V-shaped smile often requires a consultation with a dentist or orthodontist for a professional assessment and diagnosis.
