Hybrid Invisalign + Braces Plan
At 303 Smiles, you don’t have to pick between metal brackets and clear trays. Dr. Straffon combines braces' power with Invisalign's flexibility to create a smooth plan. Braces jump-start the tough bite corrections, then Invisalign trays step in to fine-tune every tooth. The payoff? A healthy, straight smile in less time and with far less hassle.
