Lip Swelling Can Be Caused by Allergic Reaction to the Braces
In certain cases, lip swelling is a sign you have an allergy to the metal in the braces, likely nickel. This is rare, but it does happen. If you are allergic to nickel, the metal braces are not a good choice, and instead, you might opt for ceramic braces, nickel-free braces, or Invisalign clear aligners. Learn more about the various braces options to see which are right for you!
If you are concerned about lip swelling or irritation, contact your orthodontist. They will examine the area and determine what is happening and how to proceed.
