Braces are a trusted and effective way to straighten teeth, correct bite issues, and improve overall oral health. Using a series of carefully adjusted brackets and wires, braces gradually guide your teeth into proper alignment, creating a more balanced and confident smile.

We have had a great experience with 1st Impressions Orthodontics. I had my bottom braces with them, and now my son has braces with them. Hopefully we don't need any more braces but if we did I would go there again. Dr. Gibson is very friendly and has been a huge help!
