Orthodontic braces can correct many dental issues, including crooked teeth and jaw misalignment, improving both the aesthetics and function of the teeth. Although braces are highly effective at correcting alignment, braces can cause pain and discomfort as the teeth are repositioned, and may even cause headaches.
reason for pain is the strain applied on the teeth by braces to move teeth so it lasts for few days until teeth are used to their new moved position. For the time being you can take analgesics( pain killers) like aspirin, paracetamol etc.
