Care Following Orthodontics – Retainers

When braces are finally removed, the “retention” phase begins..  The objective of this phase is to ensure the teeth do not regress back to their previous position.  A retainer will be used to maintain the improved position of the teeth.  A retainer is a fixed or removable dental appliance which has been custom-made to fit the teeth.  Retainers are generally made from transparent plastic and thin wires to optimize your child's comfort.

Retainers are worn for varying amounts of time, depending on the type of orthodontic treatment and the age of the child.  Perseverance and commitment are required to make this final stage of treatment successful.  If the retainer is not worn as directed, treatment can fail or take much longer than anticipated.

What types of retainer are available?

There are a variety of retainers available; each one geared towards treating a different kind of dental problem.  A retainer recommendation is made depending on the nature of the original diagnosis and the orthodontic treatment plan.

The following are some of the most common types of retainers:

  • Hawley retainer – The Hawley retainer consists of a metal wire on an acrylic arch.  The metal wire periodically adjusted to ensure the teeth stay in the desired position.  The acrylic arch is designed to fit comfortably on the lingual walls or palate of the mouth.
  • Essix – The Essix retainer is the most commonly used vacuum formed retainer (VFR).  A mold is initially made of the teeth in their new alignment, and then clear PVC trays are created to fit over the arch in its entirety. 
  • Fixed retainers – A fixed retainer is somewhat similar to a lingual brace in that it is affixed to the tongue side of a few teeth.  Usually, a fixed retainer is used in cases where there has been either rapid or substantial movement of the teeth.  It usually consists of a single wire.  The inclination of the teeth to move rapidly means they are also more likely to regress back to their previous position if a fixed retainer is not placed.

What do I need to consider when using a retainer?

There are a few basic things to consider for proper use and maintenance of your child's retainer.

Don’t lose the appliance – Removable retainers are very easy to lose.  It is advisable to place your child's retainer in the case it came in while eating, drinking and brushing.  Leaving a retainer folded in a napkin at a restaurant or in a public restroom can be costly if lost because a replacement must be created.  A brightly colored case serves as a great reminder.

Don’t drink while wearing a retainer – It is tempting to drink while wearing a retainer because of the unobtrusive nature of the device.  However, excess liquid trapped under the trays can vastly intensify acid exposure to teeth, increasing the probability of tooth decay.

Don’t eat while wearing a retainer – It can be difficult and awkward to eat while wearing a removable retainer and it can also damage the device.  Food can get trapped around a Hawley retainer wire or underneath the palate, causing bad breath.  When worn on the upper and lower arches simultaneously, VFR retainers do not allow the teeth to meet.  This means that chewing is almost impossible.

Clean the retainer properly – Removable retainers can become breeding grounds for calculus and bacteria.  It is essential to clean the inside and outside thoroughly.  Hawley retainers can be cleaned with a toothbrush.  Because harsh bristles can damage the PVC surface of a VFR, denture cleaner or a specialized retainer cleaner is recommended for this type of device.

Wear the retainer as directed – This phase of treatment is critical. The hard work has been done, the braces are off and now it is tempting not to wear the retainer as often as Dr. Dan recommends.  Retainers are needed to give the muscles, tissues and bones time to stabilize the teeth in their new alignment.  Failure to wear the retainer as directed can have regrettable consequences, such as teeth returning to their original position, added expense and lost time.
