Can speech block be treated?

Can speech block be treated? I've heard that stuttering consists of three "components": 1) repetitions, 2) prolongations, and 3) blocks—which is my problem, and it started at the beginning of my adolescence due to a traumatic event. When I speak, I hardly ever repeat or prolong words (maybe 3-5% of the time?), but I experience speech blocks. It's not very severe; if it was 50% during my adolescence (meaning it happened in every other sentence), it has now dropped to around 20-25%. But as you can imagine, it still negatively impacts my life. Can this be treated with speech therapy or another method?
