Is it OK to use toothpaste for sensitivity for longer than 4 weeks?”
The standard concentration of fluoride in fluoride toothpaste is 1,000–1,100 ppm. Toothpaste containing 1,500 ppm fluoride has been reported to be slightly more effective in reducing dental caries. However, too much fluoride can cause fluorosis. This is when fluoride builds up and creates chalky white patches on the teeth. The teeth may also become pitted. So, to answer your question, I suppose it depends on the specific brand and how much fluoride is in it. I would just follow the directions on the tube. There are some brands that are made for everyday use, such as Colgate Sensitive.
