When you get braces, you’ll most likely feel a little bit of soreness in your mouth and teeth. This feeling is expected because your orthodontist has just tightened the wires and brackets around your teeth to start encouraging them to move into alignment. This discomfort will soon wear away. In the meantime, you can apply the special wax your orthodontist gave you, consume cold liquids and foods and swish a saltwater solution around in your mouth to help relieve some of the pain.
