If I’m not mistaken in one of your other posts you mentioned you are in Canada.
This is the company I use while I’m here

If you are giving up your CDN residency as part of your plan to save on taxes this plan is great ‘cause it’ll cover you back home when you visit and the first 3 months when you move back which the CDN provincial plans won’t cover you for.
I’ve never made a claim with them and to be honest I never shopped around so can’t offer you a price/service comparison but I’m covered for dental as part of my plan.
