One.
Your Health
Crooked teeth are a challenge to keep clean. Problems with tooth brushing and flossing may lead to decay and gum disease. A healthy mouth promotes a healthy body.
Two.
Your Attitude.
The way your teeth bite together can cause a number of issues. Jaw pain, headaches, even sinus complications have been related to dental occlusion. Chronic pain and a less than cheery mien are unfortunately often paired. A lousy attitude might literally bite.
Three.
Your Smile.
A smile begets a smile. Hiding crooked teeth is sometimes just the beginning. Misaligned teeth often lead to receding gums and loss of tooth structure at the gum line, decreasing the likelihood of welcoming the world with a smile.
