How it's used
This verb is often used as a separable verb in Cantonese, meaning you can insert aspect markers like 咗 or 緊 directly between 刷 and 牙. It is a standard daily routine term that carries no special formality or slang connotations. When talking about the act of brushing, it is common to focus on the frequency or the timing relative to sleeping.
Examples
Have you brushed your teeth after waking up this morning?
I have a habit of brushing my teeth twice a day.

Common mistake
Do not confuse this with the Mandarin usage where the object 牙 is sometimes omitted or treated differently. In Cantonese, keeping the full phrase 刷牙 is the most natural way to express the action, and you should avoid trying to shorten it to just 刷.
