Teerijoki began playing bandy as a child with the bandy club
Veitsiluodon Vastus in her home town of
Kemi, a town on the southwestern coast of
Lapland. As the club did not have teams for girls, she played on the boys' junior teams and was noted as a skilled player from an early age. She won the
Finnish Championship (SM) in boys' under-12 () bandy with Vastus in 1974. Vastus created a women's representative team in the late 1970s and Teerijoki moved from the boys' junior teams to the newly created team. For the 1984–85 season, she relocated to the women's team of
HIFK Bandy in
Helsinki. Her first season with the team was a great success and resulted in her third Finnish Championship title. Teerijoki spent another two seasons with HIFK, helping the team claim the Finnish Championship title again in 1987. Remaining the most dominant player in Finnish women's bandy, she was named Women's Player of the Year in each year with HIFK – 1985, 1986, and 1987. Her excellent performance drew attention from the Finnish Bandy Association and she was named Women's Player of the Year for the tenth consecutive season. The following season, she signed with the women’s bandy team of the Norwegian multi-sport club
Hasle-Løren IL in the ('Norwegian Championship in bandy for women'). With Hasle-Løren, she was
Norwegian Champion in women’s bandy in 1989 and 1990. For the 1989–90 season, she also played with the men’s representative bandy team of Tåsen IL in the ('Division 1 bandy for men') and earned her eleventh selection as the Finnish Bandy Association's Women's Player of the Year. Returning to Sweden for the 1990–91 season, she played with the women’s representative bandy team of
Västerstrands AIK. In a repeat of the success found in her rookie season, Teerijoki topped the league's scoring charts, this time with 41 points in ten games, and led her team to victory in the 1991 Swedish Championship. She won the Swedish Championship with Västerstrands AIK again in 1994. At one point, the men's representative team of
HIFK Bandy took steps to sign Teerijoki to their roster but the Finnish Bandy Association responded by institututing a new rule baring a woman from playing on a men's team. Though she was never able to play in the
Bandyliiga herself, Teerijoki coached the HIFK men’s representative team in the 1993–94 Bandyliiga season. Women's bandy in Finland experienced a sharp decline in popularity during the 1990s and Teerijoki opted to focus on other sports for many years, ending her career as a bandy player in 1994. In the late 2010s, Teerijoki returned to national-level bandy competition, playing with the HIFK Bandy women's team in the ('Finnish Championship Series in Women's Bandy'). She was named the 2020 Naisten SM-sarja Player of the Year after leading her team in scoring and ranking fifth in the league overall, with 17 points (10+7) in nine games. Regarding her selection, 56-year-old Teerijoki said, "I am happy and grateful but probably think that someone else could have won." , Teerijoki is a member of the Women's and Girls' Bandy Committee of the Finnish Bandy Association.
