Any tips for mastering the 'ts' and 'dz' sounds in Armenian?

I record myself reading Eastern Armenian poetry every day, but my playback is killing me. I keep mispronouncing the 'ts' (ց) and 'dz' (ձ) sounds, and I'm worried I've already fossilized the wrong tongue placement. Since I record myself often, is there a specific way to visualize or practice the dental-alveolar transition to make it sound more authentic?
