Sensodyne Repair and Protect toothpaste is designed to provide sensitivity relief and cavity protection. Its active ingredient is stannous fluoride, which builds a repairing layer over the vulnerable areas of the teeth and protects them from sensitivity tooth pain. The inactive ingredients include glycerin, PEG-8, hydrated silica, and others. The product is recommended for adults and children 12 years of age and older. Some positive aspects of the product, as reported by customers, include effective relief from sensitivity pain and a fresh taste. However, some users may not like the taste or texture of the toothpaste. It is important to note that sensitive teeth may indicate a serious problem that may need prompt care by a dentist, and if pain or sensitivity persists after 4 weeks of use, a dentist should be consulted. The product should be kept out of reach of children, and if more than used for brushing is accidentally swallowed, medical help should be sought.
