Shaun Weiss -- famous for playing Goldberg in "The Mighty Ducks" -- is doing well on his road to recovery following his most recent meth bust ... but he could still use a little help in one area.
Shaun's at a sober living facility in Woodland Hills, where he's staying clean and going to outpatient meetings 5 days a week ... but he could use some new pearly whites, because they're all gone.
His good friend, Drew Gallagher, set up a GoFundMe to help get Shaun a full set of teeth .
