What's the best gum to buy for dry mouth?

I’m going to try chewing gum in the middle of the night when i wake up from dry mouth to stimulate my saliva, but I know there are certain ingredients in certain gums that are better for dry mouth supposably? Seeing that some kills bacteria? like supposably ice cube breakers gum or whatever..

anyways I know that there are dry mouth mouthwash and biotene products out there, but I want to try this first to see if it works…
