Mail-order aligner kits are cheaper upfront, and that is real. What they leave out is everything else: nobody examines your gums before your teeth start moving, the impressions are taken on your kitchen bench, and if tracking slips you are emailing a help desk.
At Dental Folk, Aligner Lite starts from $4,500 for mild cases and comprehensive treatment from $7,000, with your case checked by several orthodontists before we commit to a plan. The $450 records consultation comes off your treatment price in full, and retainers at the end are $300, quoted from day one.
