Bite guard

[James40]

I got a soft bite guard about 4 weeks ago. It’s transparent rubber material and fits around most of my top teeth and partly over my palate. It’s comfortable enough, although my mouth is a bit dry on the morning, but even though I brush it with toothpaste before I put it in at
night it has turned yellow and smells disgusting. What can I do to sort this out?

Try denture cleaning tablets and keep it in water during the day.
