Essix retainers are devices used to hold teeth in place after surgery or a realignment procedure. Retainers made of Essix plastic are aesthetically-pleasing to patients who wish to avoid wearing a visible wire, states Braces San Diego.
Essix plastic is clear in appearance and has multiple advantages, notes the Oral Health Group. An advantage of using Essix retainers is that they are cost effective. They are known to be quite durable, are worn only at night and do not interfere with normal hygienic practices. Their flexibility increases comfort because they easily conform to movements of the mouth.
