In 2004 Wang became China's National All Around Champion and Triple Silver Medalist during Event Finals (vault, uneven bars and floor).

In the 2004 Summer Olympics in Athens she qualified for the Vault finals and the Individual All-Around.

She fell on her beam dismount in the Individual AA competition and scored an 8.725 (she ended up 13th that night).

In October, 2005, Wang Tiantian competed at the National Games, but a nagging foot injury hampered her performance.

The injury kept her out of the East Asia Games several weeks later and eventually required surgery at the end of 2005.
