Retainers are dental appliances that are used to keep teeth in their correct position after orthodontic treatment. They are typically made of clear plastic or metal, and they are worn over the teeth for a period of time each day or night. The cost of retainers can vary depending on the type of retainer that is used, the materials that it is made of, and the length of time that it is needed.
The most common type of retainer is a clear plastic retainer. These retainers are made of a thin, flexible plastic that is custom-fitted to the teeth. Clear plastic retainers are relatively inexpensive, and they are typically worn for a period of time each day or night. Metal retainers are another option. Metal retainers are made of a thin, metal wire that is custom-fitted to the teeth. Metal retainers are more durable than clear plastic retainers, but they are also more visible. Metal retainers are typically worn for a period of time each night.
