'Mighty Ducks' Star Shaun Weiss Is 170 Days Sober, But Needs New Teeth

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 ... and he's trying to raise $25,000 for some much-needed dental work and his ongoing sober-living.

As you can see in this latest pic of Shaun ... he's looking much better and happier. He was having breakfast this week with Drew when the picture was taken ... a meal celebrating 170 days sober.

It's another milestone for Shaun, who finally went to rehab in March after getting out of jail and completed a 90-day program at Quest 2 Recovery in Lancaster.

As we first reported ... Shaun's buddies were desperate to get the troubled child star help before it was too late -- he was dealing with a slew of life-threatening issues and was at one point, living on the streets before January's meth and burglary arrest.

Shaun keeps looking better and better ... so hopefully, he keeps getting the help he needs, including some new teeth.
