aluminum nipples won't increase the risk of losing one's teeth in an accident. rather, they are more likely to freeze to the spokes and get stripped when trying to turn them with a spoke wrench.
On front wheel or rear drive-side, spoke tension is high enough to not worry about a thread-locker. But on the non-drive-side of a dished rear wheel, spokes are a notably lower tension and can loosen over time, and it's more worth using something that makes loosening less likely. Weaker versions of loctite can work, or spoke prep. I use boiled linseed oil, which functions as a "stiff lubricant".
And I've used brass nipples for all the wheels that I build.
