He may have lost two teeth in a bathroom fall during a South American tour with Aerosmith, but singer and "American Idol" judge Steven Tyler has not lost his sense of humor. "You can't handle the tooth!" he joked in a phone interview with TODAY's Matt Lauer, which caused an outburst of giggles around the studio.

The incident occurred on Tuesday, when Tyler says he walked into his hotel shower in Paraguay, "got nauseous (from food poisoning), started to get sick and I fell on my face and I just passed out."

"I woke up with the water running on me ... and the next thing you know my tour manager was calling the American Embassy and we found the best hospital," he said.

The 63-year old Tyler spent almost four hours at a medical center in Paraguay's capital, according to reports. He told Lauer he received four stitches in his eye. The Hollywood Reporter indicates he also received dental implants.

"I walked out of the shower looking like Leon Spinks," he told Lauer, as photos of his battered face -- with gap-toothed grin -- were shown.

But this was not a fall off of the wagon, says Tyler, who relapsed from decades of sobriety in late 2009 and underwent three months of rehab. "That's not the issue," he told Lauer.

"People thinking that is natural and normal," he continued. "(Aerosmith) flew last night from Paraguay after that incident, and we're in Argentina for two hours. And anybody who knows anybody who uses substances wouldn't be up at this hour having a talk with Matt Lauer and the rest of America. It's nothing I don't understand. It makes me a little upset. But I get that people think that. It's something that bothers me and it's something I'll have to deal with for the rest of my life."

Quickly, though, he was back to joking and talking about the show he played Wednesday night -- the one he was supposed to have played on Tuesday.

"Short of having my leg taken off, people are going to expect me on stage no matter what," he said. "I went out on stage and wore my sunglasses for the first song. I took them off and the crowd roared. It's all about playing to the people. ... We rocked. ... Not only did I break my face, but we broke a house record, so life is beautiful, Matt."
