It’s important to remind your child that having braces is only a temporary process that will give them a beautiful smile for a lifetime. If possible, start the orthodontic treatment as early as possible. Most kids are more comfortable wearing braces during their middle school years, when a lot of children are more likely to have them, than in high school. If you really want to drive it home that braces are a norm and nothing to be ashamed about, consider Googling famous actors and musicians who wore braces.
Ultimately, just help your kid to realize that braces are a common occurrence, work in a “quick” process, and will benefit them for a lifetime.
