Former world No 1 Tiger Woods has a million dollar smile - well, he used to at least.

While his girlfriend Lindsey Vonn was busy breaking records at the Skiing World Cup, Woods was pictured looking nothing like himself, the 39-year-old sported a crooked smile with one of his front teeth missing.

It is so far unclear how he lost the tooth, with some reports speculating that Woods (above, left, at the Skiing World Cup and in December, right)will have the missing incisor replaced as it had become discoloured in recent weeks.

Having suffered an injury hit 2014, Woods will return to the course for the first time in 2015 at the Waste Management Phoenix Open in January.

Vonn, 30, recorded her 63rd World Cup victory in Austria to break Annemarie Moser-Proell's 35-year-old record.

The American clocked 1 minute 27.03 seconds down the Olympia delle Tofane course to finish 0.85 ahead of Anna Fenninger of Austria, while Tina Weirather of Liechtenstein was third, 0.92 back.

Woods surprised Vonn in the finish area, where the pair shared an emotional embrace. Vonn exclaimed: "No way!" when she saw him.

"I didn't think this could get any better than yesterday with my entire family here but now with Tiger here this is unbelievable," Vonn said. "I said, `I can't believe you came.' And he said, `I told you."'
