My Tibbe's tendency to tangle got way better as he aged and his coat matured. Treats and patience in short sessions as advised above are great ways to work through these things. If one got too bad, I cut into part of it here and there with a tiny snip or cut it off rather than put Tibbe through any discomfort.
