Yes. OrthoFx offers a subscription service for their retainers, so you don’t have to order more when it’s time to replace them. The price per retainer changes depending on how frequently you choose to replace them. For every three months, each retainer set is $99. For every six months, your retainer set is $149. For every twelve months, each retainer set is $324. These are significantly higher prices than almost all of OrthoFx’s competitors.
