When can we introduce toothpaste to babies

Hi Mummies, My boy will be 10 months old soon and I am curious to know when is the right time to start toothpaste for him? I already clean his teeth with the finger brush but I just use water currently. I am concerned that if I use toothpaste now and he doesn’t know how to spit, the paste will remain in his mouth. How do you mummies deal with it ? When is the right time to introduce ? Help this first time mumma please :) ##firsttimemom #advicemommies
