My dentist gave me fluoride treatment in-office and told me that my teeth may be sensitive due to multiple dental treatment especially crown, but no obvious symptoms. So I couldn't crown and do my night guard for the time being. He also said I needed fluoride to protect and strengthen my teeth, and to monitor my sensitivity for few months before going back to my dental check-up. If not, he will need refer me to see a specialist. Can I use toothpaste for sensitive teeth and rinse with fluoride mouthrinse and how long should I monitor for and using the toothpaste for sensitive teeth
