How Long Can Retainers Last?

How Long Can Retainers Last?

Unfortunately all plastic retainers will degrade and deform over time to the point 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. Plastic retainers will typically last 12-24 months.

The Somnowell chrome cobalt alloy retainers are like the plastic vacuum retainers, but visibly smaller and more discreet. They are made of cast chrome cobalt alloy which like gold is an ideal material for long term use in the mouth. It does very resilient and strong and does not suffer wear or tear in the mouth. The surface is highly resistant to oral fungi and bacteria, making it easy to clean and a more hygienic option. Chrome cobalt retainers will last indefinitely.

Once the teeth have moved orthodontic work will be required to move them back. If you're lucky they are going to have only moved very little, it is possible the vacuum retainer can be used as an aligner and will move the teeth back.
