Being aroused generally reduces this reflex. I think I trained it a long time ago by rubbing the roof of my mouth with a (very clean) finger. Eventually I could play with my uvula. I cemented this skill by years later, training with a dildo.

Interesting, toothbrushes still bother me, and especially brushing around my tongue is a huge trigger. I don't brush my tongue and definitely not under my tongue.
