Common Reasons People Seek Clear Aligners
Crooked or Misaligned Teeth
Crowding or rotated teeth are common among adults and teens. Straight teeth are easier to clean and maintain, reducing the risk of decay or gum disease.
Misaligned Bites
Deep bites, crossbites, and open bites affect chewing, jaw strain, and long-term stability. Addressing these early, or correcting them in adulthood, prevents complications.
Confidence and Natural Aesthetics
Many adults and teens want a harmonious smile without obvious braces. Clear aligners, particularly discreet systems like Angel Aligners, are ideal for subtle, lifestyle-friendly treatment.
