We recommend seeing your dental professional in-person, but there are various online or by-mail services you can use. These at-home services are still unproven but ordering aligners online can be more convenient and cost effective than going to a dentist. If you feel confident ordering online, it’s worth doing a bit of homework to make sure you’re happy with the credentials of the company you want to use. Check out reviews, pick up the phone or live chat to find out what input you get from a dental professional and what assurances they provide if you’re unhappy with the fit. Different online providers may have slightly different products, steps and services. Make sure you get the answers you need and are happy with your conversations with them before you go ahead.
