I have heard the clear retainers are only good for one year. So what do I do now?

Hello There,Thank you for your question. Clear retainers are usually good for 6-12 months and then need to be replaced in order to keep your teeth from shifting.I suggest to go to your dentist and get an impression done for new retainers. If your retainers were done through Invisalign they may already have your records on file. Through Invisalign you may purchase one or do a pack of 4 (vivera retainers) that may last you up to 4 years.Hope this answered your question. Good Luck!

Thank you for the question. We recommend patients wear retainers nightly to keep the teeth in the same position they were in when the braces came off.  Retainers will typically be last for 1-2 years before they need to be replaced. Factors that can influence how long a retainer will last are the patients bite and if they grind or clench their teeth. Once a retainer has holes or cracks it looses its integrity and its effectiveness. Consistent retainer wear is a lifelong commitment and replacing a retainer is much easier than redoing braces. 
Thank you,
