Given vectors $\overrightarrow{a}=(1,- \sqrt {3}\sin \dfrac {x}{2})$ and $\overrightarrow{b}=(\sin x,2\sin \dfrac {x}{2})$, the function is defined as $f(x)= \overrightarrow{a} \cdot \overrightarrow{b} + \sqrt {3}$.
(1) Find the interval(s) where $f(x)$ is increasing;
(2) Find the minimum value of $f(x)$ in the interval $[0, \dfrac {2π}{3}]$.
