Halt early gum disease and get healthy teeth with professional deep cleaning, daily antibacterial rinses, and more-frequent dental care visits (typically once every 3 months). If you have sensitive teeth, ask your dentist about topical fluoride or other prescription desensitizing agents. Over-the-counter fluoride rinses or sensitive teeth toothpastes can also help. And go easy on bleaching, which can temporarily increase sensitivity. (Always check with your dentist before beginning to bleach.)
