I have teeth that slant inward, what are my options? (Photo)

I have teeth that slant inward. It may be from teeth shifting after a full mouth bite adjustment. I now bite cheeks at night, nip-pinch tongue edges. My already crooked teeth seem more crowded and closer. A prostodontist thought braces that can possibly even extrude teeth a bit for more height? Another said go with Invisalin? Another thought crowns? I'm trying to keep things simple. I am 70 and not rich. Your thoughts are appreciated. Need to get out of pain so I don't poke, bite soft tissues.
