Retainers are an essential part of the process for aligning the teeth. Once braces are removed, retainers ensure that the teeth remain in their newly aligned position. There are a variety of different retainers and it is important to understand how to properly use and maintain your retainer.

What are retainers?
When braces are finally removed, the “retention” phase begins for most individuals. The objective of this phase is to ensure the teeth do not regress back to their previous position. A retainer will be used to maintain the improved position of the teeth. A retainer is a fixed or removable dental appliance that has been custom-made by the orthodontist to fit the teeth. Retainers are generally made from transparent plastic and thin wires to optimize the comfort of the patient.
Do I need to wear a retainer?
Retainers are worn for varying amounts of time, depending on the type of orthodontic treatment and the age of the patient. Perseverance and commitment are required to make this final stage of treatment successful. If the retainer is not worn as directed, treatment can fail or take much longer than anticipated.
What types of retainers are available?
There are a variety of retainers available, each one geared towards treating a different kind of dental problem. The orthodontist will make a retainer recommendation depending on the nature of the original diagnosis and the orthodontic treatment plan.
The following are some of the most common types of retainers:
- Hawley retainer – The Hawley retainer consists of a metal wire on an acrylic arch. The metal wire may be periodically adjusted by the orthodontist to ensure the teeth stay in the desired position. The acrylic arch is designed to fit comfortably on the lingual walls or palate of the mouth.
- Essix – The Essix retainer is the most commonly used vacuum formed retainer (VFR). A mold is initially made of the teeth in their new alignment, and then clear PVC trays are created to fit over the arch in its entirety. VFR’s are much cheaper than many other types of retainers and also do not affect the aesthetic appearance of the smile in the same way as the Hawley retainer. The disadvantage of VFR’s is that they break and scratch more easily than other types of retainers.
- Fixed retainers – A fixed retainer is somewhat similar to a lingual brace in that it is affixed to the tongue side of a few teeth. Usually, a fixed retainer is used in cases where there has been either rapid or substantial movement of the teeth. It usually consists of a single wire. The inclination of the teeth to move rapidly means they are also more likely to regress back to their previous position if a fixed retainer is not placed.
