Some toothpastes have ingredients such as stannous fluoride and potassium nitrate that can help with sensitivity. Potassium nitrate has worked for me personally. Since sensitivity can be caused by various dental issues including receding gums, cavities, and dry mouth, sensitivity should be discussed with your dentist or dental hygienist.
I work at two dental offices and the toothpaste samples given to patients vary. I rely on my colleagues and my professional network to learn about any problems or issues with toothpastes rather than claims from the companies that make them. For example, there was a toothpaste on the market that had blue beads in it. When hygienists began finding these beads embedded in people's gums, the alarm was sounded and the manufacturer corrected the problem. Stannous fluoride has had issues as well. It was found to stain the teeth and manufacturers have since added ingredients to counteract this.
In addition to stannous fluoride, sodium fluoride and sodium monofluorophosphate can be found in toothpastes. They are all effective and essentially do the same thing: provide some fluoride directly to the teeth and into the saliva. A dentist may prescribe a toothpaste with a higher amount of fluoride if a patient needs it due to their dental condition.
Finally, teeth must be brushed regularly regardless of the type of fluoride in the toothpaste. It seems simple, but people rarely brush for long enough, or brush only once a day. Brushing and flossing physically removes plaque germs from the teeth and gums. While toothpaste is important, this is the most important aspect of caring for the teeth. Brushing the teeth 2 to 3 times a day for 2 minutes (set a timer) will clean teeth and create a healthy mouth.
