We use two main types of retainers on the upper arch. The main one, called Essix, is a clear plastic shell covering the teeth, sometimes only six front teeth. It must be worn full time for two weeks, except for meals and brushing, then at night only for a period of at leat one year. We use this appliance frequently but it is not ideal for every case. If you have this type of appliance, it is possible that it will show some signs of wear or perforation with time. This is normal and will not affect the performance of the retainer. If the appliance breaks or cannot be worn, call us.
The other type of upper retainer is a “Hawley”. It is made of acrylic, clasps on the molars and a front wire helping maintaining the teeth in place. It must also be worn full time (except for meals and brushing), during 6 to 8 months. After that period, it can be worn at night only or according to the instructions we will give you.
It is possible that fixed splints be bonded on the tongue side of some teeth. If these retainers become loose or fall off, save them and call our office so that we can determine if they need to be rebonded. These upper fixed retainers, just like the lower ones, can be left in the mouth for many years.
Always bring your removable retainers with you when you come for check-up visits.
