What is the Difference Between Plastic and Metal Retainers?

Unfortunately acrylic plastic retainers will degrade and deform over time to the point that the retainer must be replaced. Retention is a serious commitment and any plastic retainer is therefore fundamentally a short term solution. Another issue with the acrylic plastic is that it will quickly become colonized by oral fungi and bacteria. This makes them unsightly and unhygienic.

As a consequence these acrylic retainers require intensive cleaning and upkeep to extend their lifespan and to try and keep them reasonably hygienic. They cannot be sterilized and are a long way from ideal in terms of oral hygiene. 

The Somnowell chrome cobalt alloy retainers are small and discreet and will effectively keep all of the teeth in their new positions. Chrome cobalt is a well-established material used to make the highest quality dentures. It is very strong in thin section and extremely robust. Chrome cobalt alloy does not deform or degrade in the oral environment and shouldn't need to be replaced. The material surface is highly resistant to oral fungi and like gold is an inactive metal excellent for long term use in the mouth. The chrome cobalt retainers will always remain clean, fresh, and comfortable.
