Most people assume the only reason that you need braces is that you want your teeth to be straight. Braces can also correct cosmetic issues and improve a wide number of health issues in both the dental and physical category. Braces can straighten crooked teeth, which is their primary function. Straighter teeth are easier to clean. Braces can also align teeth.
If your teeth are even somewhat out of alignment, you might find yourself clenching or grinding your teeth, especially as you sleep. Properly aligned teeth can lead to fewer jaw aches. Braces correct a misaligned bite. An overbite occurs when the upper jaw comes out in front of the lower jaw when you bite down. Underbite occurs when your lower jaw overlaps your upper jaw.
