If you want to keep that new smile after orthodontic treatment, you’ll need to wear a retainer for awhile. Teeth have a tendency to “rebound” to their old positions and a retainer prevents that from happening.
Most people are familiar with the standard removable retainer. But there’s another option: a bonded retainer. While performing the same function as a removable one, the bonded retainer differs in one important aspect—it’s fixed in place and can’t be removed except by a dentist. It’s especially useful for certain bite repairs like the closure of the gap between the front teeth.
If you’re thinking this retainer sounds a lot like the braces just removed, it’s not. The main part of a bonded retainer is a thin metal wire that we bond with a dental composite material across the back of the affected teeth. While you can definitely feel it with your tongue it can’t be seen by others, which is an advantage over many removable retainers.
The fixed nature of bonded retainers also creates a couple of advantages, especially for younger patients. There’s no compliance issue as with removable retainers—the patient doesn’t have the option of taking it out. That also means it can’t be lost, a frequent and costly occurrence with the removable variety.
But a bonded retainer does have some drawbacks. For one, the wire and composite material make it more difficult to floss. There’s also a possibility of breakage from high biting forces, which if that should occur must be immediately repaired to avoid the teeth rebounding. But while removable retainers have their downsides, it’s much easier with them to keep the teeth clean of plaque—you simply take the appliance out to brush and floss.
With your dentist’s help you can weigh the pros and cons of both types of retainers and decide which is best for you or your child. Whichever one you choose, wearing a retainer will help protect that hard-earned smile for years to come.

On the day when braces come off, most people feel that their orthodontic treatment is over. When they are then asked to wear retainers, they may wonder what this additional requirement will accomplish. Wasn't the work of moving their teeth to desired positions already completed? To understand the answer to this question, you need to understand how orthodontics works.
How does orthodontic treatment remodel your smile?
Although they give the appearance of being stable and unmoving, teeth and their surrounding structures (gums, jawbones, and ligaments) are living tissues and are actually in a constant state of change.
Teeth are rooted in bone and are attached by a fibrous tissue called the periodontal ligament (from peri meaning around and odont meaning tooth). One side of the ligament attaches to the cementum (part of the tooth's root) and the other side is attached to the bone, with the tooth suspended in between.
These tissues are constantly remodeling themselves, but pressure from the lips and cheeks on one side and from the tongue on the other create a balance that keeps the teeth suspended in the same location. When mild forces are placed on the teeth, such as the forces from the wires used in orthodontic treatment, the tissues slowly adapt and rebuild, resulting in a new position for the teeth.
What are retainers?
Orthodontic retainers are devices usually made of a clear plastic section that is fitted to the roof of the mouth, with thin wires that fit over the teeth.
What is the purpose of retainers?
The remodeling process keeps going after the orthodontic treatment stops, so time is needed for the teeth to reach a new balanced state. The retainer stabilizes them in their new position so that bone and ligament can reform around the teeth and hold them there. This works well for adolescents, whose jaws are in a state of growth, but adults may need outside assistance to stabilize their teeth for a longer time. They may be asked to wear retainers indefinitely to make sure their teeth do not move from their new positions.
What happens if you don't wear your retainers?
If you don't wear your retainers, your teeth are likely to return to the positions they had prior to your orthodontic treatment. This can happen fairly rapidly, underscoring the importance of wearing retainers as instructed.
What are the different types of retainers?
Most retainers are removable devices as described above. For people who require long-term use of retainers, thin retainer wires can be bonded to the inside surfaces of their front teeth. Such wires are usually left in place for several years, relieving them of the need to remove and replace their retainers.
