What causes cold sensitivity?

Have you ever experienced a jolt of pain while taking a breath of cold air or a sip of a cold drink? If so, you may have sensitive teeth as a result of tooth decay, a broken tooth, worn fillings, periodontal (gum) disease or exposed dentin (the part of teeth that's connected to sensitive nerves). The good news is that there are lots of treatments available, so you don't have to live with pain from tooth sensitivity! Learn more here: http://bit.ly/1fSKSiw
