Double check with your dentist. I generally suggest soaking them, as directed, in a denture cleaner such as Polident or Fixodent. Then, with a denture toothbrush, you dip the toothbrush in the solution and use that to brush the entire denture. Don't use the denture toothbrush on your teeth. Using your own toothbrush, then brush your own teeth. Be sure to get everything clean. Good luck and use your new teeth in good health.

No toothpaste extra soft bristle toothbrush brush and every surface and material on the partial daily under warm water and soak it in something like efferdent (follow the instructions for how long to soak it for)
