Here's why:
* Overbites are a complex dental issue: They can be caused by a variety of factors including genetics, thumb sucking, tongue thrusting, crowding, and even environmental factors like diet.
* Variation within populations: Even within a specific population, there is significant variation in dental features. You'll find people with overbites, underbites, and perfectly aligned teeth within all nationalities.
* Stereotypes are harmful: Generalizing about the appearance of an entire group of people based on nationality can lead to harmful stereotypes and discrimination.
It's important to remember that every individual is unique, and their dental features are influenced by many factors.
