A retainer is a dental appliance that is used to hold teeth in place after orthodontic treatment. Retainers can be made of a variety of materials, including plastic, metal, and ceramic. They are typically worn at night and sometimes during the day.
There are a few different ways to get a retainer without going to the dentist. One option is to order a custom-made retainer online. There are a number of companies that offer this service. Another option is to purchase a generic retainer from a pharmacy or drugstore. These retainers are not custom-made, so they may not fit as well as a custom-made retainer.
