Although some people wear braces primarily for cosmetic reasons, there are a number of health benefits to having straighter teeth. Teeth that are straight are easier to clean, which helps to prevent tooth decay and gingivitis. Many structural issues can be resolved by correcting the bite, which can minimize jaw pain and make chewing easier. You may look like you have straight teeth, but your bite may be wrong, your dentist will be the best person to talk about this with for a personalized recommendation.
