Why do I need a retainer? What type should I choose?

When a patient is at the end of their active orthodontic treatment they move into the retention phase of treatment. The purpose of retainers is to maintain the corrected alignment of the teeth. Sometimes the teeth want to relapse back to their original positions. For this reason patients are encouraged to practice loyal and frequent retainer wear.

The length of time a patient wears a retainer varies also. Their are basically three different types of retainers which will be described in more detail in the following paragraphs. Each type has their strengths and weaknesses and the doctor will discuss which type is best for you. The recommended wear for removable retainers is every night in the beginning and then a few nights a week after 6 months.

Removable Hawley Retainer- Hawley retainers consist of a hard acrylic (plastic) that covers the roof of the mouth or the tongue side of the lower arch and is combined with a wire in front of the teeth. This works to hold the teeth in place with light force against the front of the teeth. The acrylic is available in different colors. We sometimes use a variation of this retainer, a spring retainer, to move teeth into position if they have moved slightly. This is done with little springs placed in the acrylic.

Essix or shell retainer- This retainer resembles an Invisalign tray. It is made with clear plastic that covers all the teeth. It is made with a vacuum that sucks the plastic down over a model of the patients teeth. It is an excellent retainer in holding spaces closed and is very esthetic. Due to the thin esthetic plastic this retainer deteriorates at a faster rate than the Hawley and will need to be replaced more frequently.

Fixed or permanent retainer- These are customized wires that have been fitted to the tongue side of your front teeth. They are bonded to the teeth and can make flossing a little more challenging. They are excellent for maintaining the position of the front teeth.

Care and maintainence of all three types is important. Food and bacteria can adhere to any retainer. Please use a toothbrush to remove the debris. Soaking retainers in denture cleaners or a retainer cleaner will also help remove debris. Never boil or microwave any retainer, this will distort the retainer and it will no longer fit properly. Flossing and brushing is the best method to keep fixed retainers clean.

If you have any questions or concerns regarding your retainer, please talk to your doctor, they can always find a solution!!
