He graduated from Yucaipa High School in 1999 and attended St. Mary's College in California. Teahen was drafted 39th overall in the 2002 draft by the Oakland Athletics with a sandwich pick between the first and second rounds. Teahen was one of the featured players in the book Moneyball, which claimed that Teahen had the potential to become the next Jason Giambi.
Prior to the 2009 World Baseball Classic, Teahen, whose father was born in St. Marys, Ontario, became a naturalized Canadian citizen and played for Team Canada in that event. In 2011, Teahen and Brett Lawrie both started in the infield for the Blue Jays, marking the first time the squad had two Canadians in its starting lineup.
Professional career 
Kansas City Royals 
Oakland traded him to Kansas City in 2004, along with Mike Wood, as part of a three-way trade that sent Carlos Beltran to the Houston Astros, Octavio Dotel from the Astros to the Athletics, and John Buck from the Astros to the Royals. Although he had been one of the most highly regarded prospects in the Oakland organization, he became available when the Athletics were able to sign Eric Chavez to a long-term contract.
Royals management did not expect Teahen to make the opening-day roster in 2005; however, after hitting .344 in spring training and after injuries sidelined potential third basemen Chris Truby and Chris Clapinski, the Royals announced Teahen would be their regular third baseman for 2005, and he made his major-league debut on April 4, 2005.
His first hit was a triple and he hit 4 homers in his last 17 games of 2005. Teahen hit .240 in his rookie season with KC. He had the lowest fielding percentage of all third basemen in the league, .947, and the lowest zone rating of all major league third basemen (.706).
In 2006, he hit .290 with 18 home runs and 69 RBIs. During July, he raised his performance level with 10 home runs and 35 RBIs during the 38 games ending August 2. He continued to hit well, but suffered an injury and had to have season-ending surgery on September 8.
Going into the 2007 season, Teahen moved from third base to right field because of the arrival of young prospect Alex Gordon. His HR total dropped alarmingly to only 7 homers, after hitting 18 the year prior. During the 2008 season, he hit two inside-the-park home runs (leading the majors), bringing his total for 2008 to 14 HRs.
While in Kansas City, Teahen was a spokesman and fundraiser for a program that gave children with physical or mental challenges the chance to play baseball. Since Teahen obtained dual Canadian-American citizenship in 2005, he was able to play for the Canadian team in the 2009 World Baseball Classic. In 2009, he hit .271 with a career-high 34 doubles, 12 home runs and 50 RBI in 144 games with Kansas City. He made 99 starts at third base, 31 in right field and three at second.
Chicago White Sox 
On November 5, 2009, Teahen was traded by the Royals to the Chicago White Sox in exchange for infielders Chris Getz and Josh Fields. He later received the 2009 Hutch Award for his efforts on and off the field.
On December 8, Teahen and the White Sox agreed to a three-year, $14 million deal.
Toronto Blue Jays 
On July 27, 2011, Teahen was traded to the Toronto Blue Jays with Edwin Jackson for Jason Frasor and Zach Stewart. The Blue Jays designated him for assignment on January 9, 2012. He was released on January 17.
Washington Nationals 
Teahen signed a minor league contract with the Washington Nationals on February 6, 2012. Teahen spent the 2012 season with the Nationals Triple-A affiliate Syracuse Chiefs. According to the International League transactions page, Teahen declared Free Agency on November 2, 2012.
Arizona Diamondbacks 
On November 26, 2012 he signed a minor league contract with the Arizona Diamondbacks.
