 Hey, you. Yeah, you. This is your dentist. Do me a favor and feel the front of your teeth. How grimy are they? It's time for a Crest Pro Health reality checkup. That grime is the buildup of plaque bacteria that can cause cavities in just months. You need to switch to Crest Pro Health. While most toothpaste stop working in minutes, Crest Pro Health's antibacterial fluoride protects for up to 12 hours to stop cavities before they start. So pick some up on the way home. Smile. Crest has you covered.
