I have had sensitive teeth for a long time. I have used both name brand and store brand sensitive toothpastes and all have worked well! I received a sample of the Cinnamon Pro Health toothpaste from my dentist and liked it, so I bought a tube. After one month of using Pro Health Cinnamon toothpaste, my teeth are unbearably sensitive. They hurt if I eat or drink anything colder or hotter than tepid water. This toothpaste seems to clean well, but it does not help with sensitivity. I will be switching back to another brand's sensitive toothpaste tonight.
