There is nothing like the best toothpaste. Any toothpaste with the right amount of calcium & fluoride content should be used regularly, by a healthy adult. Fluoride free toothpaste should be used for children under 5 years of age. Specialized toothpaste with desensitizing agent, whitening agents, etc. should be strictly used under medical prescription. Avoid using gel based toothpaste & herbal toothpaste with high abrasive content.
