Colgate Total

Consumer Reports is one of the few reviews we find that is based on lab tests, but that review emphasizes stain removal and taste and leaves any determination of clinical effectiveness to the ADA. Slate.com publishes a big comparison review that includes both subjective taste and texture ratings and dentists' recommendations. We also find several toothpaste reviews of Colgate Total written by dentists, based on their professional education and experience.

Experts recommend Colgate Total more often than any other toothpaste. It's approved by the American Dental Association (ADA) and contains both fluoride and triclosan -- a broad-spectrum antibiotic -- to kill bacteria that cause cavities and gum disease. A copolymer allows the triclosan to remain active between brushings, even after you eat or drink. Colgate Total is not recommended for kids under 6 since its antibacterial properties have not been tested for young children. It's moderately abrasive and contains sodium lauryl sulfate, which can sometimes irritate sensitive mouths. For people prone to canker sores or sensitive teeth, reviews recommend Sensodyne Pronamel (*est. $5.50 for 4 oz.), which contains fluoride but not SLS.
