Tony Hawk -- Oops, I Broke My Face!

Lil Wayne shouldn't feel too bad about his skate park accident the other day ... because even the greatest boarder of all time isn't immune to a crash every now and then.

The legendary Tony Hawk smashed his face in during a doubles session at the Kona Skate Park in Jacksonville, Florida yesterday ... leaving the 43-year-old with a very snaggled front tooth.

After the fall, Hawk -- who's now headed to Georgia -- tweeted, "Oops, doubles with Staab went wrong at Kona. Anyone know a good dentist in Savannah?
