What do a teenager with a poor bite, a senior citizen with multiple missing teeth or a middle-aged person with a teeth grinding habit all have in common? They may all depend on a dental appliance for better function or appearance.
There’s a wide variety of removable dental appliances like clear aligners or retainers for orthodontic treatment, dentures for tooth loss or night guards to minimize teeth grinding, just to name a few. But while different, they all share a common need: regular cleaning and maintenance to prevent them from triggering dental disease and to keep them functioning properly.
The first thing to remember about appliance cleaning is that it’s not the same as regular oral hygiene, especially if you have dentures. While they look like real teeth, they’re not. Toothpaste is a no-no because the abrasives in toothpaste designed for tooth enamel can scratch appliance surfaces. These microscopic scratches can develop havens for disease-causing bacteria.
Instead, use liquid dish detergent, hand soap or a specific cleaner for your appliance with a different brush from your regular toothbrush or a specialized tool for your particular appliance. Use warm but not very hot or boiling water: while heat indeed kills bacteria, the hot temperatures can warp the plastic in the appliance and distort its fit. You should also avoid bleach—while also a bacteria killer, it can fade out the gum color of appliance bases.
Be sure you exercise caution while cleaning your appliance. For example, place a towel in the sink basin so if the appliance slips from your hands it’s less likely to break hitting the soft towel rather than the hard sink. And while out of your mouth, be sure you store your appliance out of reach of small children and pets to avoid the chance of damage.
Cleaning and caring for your appliance reduces the risk of disease that might affect your gums or other natural teeth. It will also help keep your appliance working as it was designed for some time to come.
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.

Orthodontics shares a principle with the classic tug of war game: if you want things to move in the right direction you need a good anchor. Anchors help braces and other appliances apply constant pressure to misaligned teeth in the direction they need to go to correct a malocclusion (poor bite).
Orthodontic treatments work in cooperation with an existing oral mechanism that already moves teeth naturally in response to biting forces or other environmental factors. The key to this mechanism is an elastic tissue known as the periodontal ligament that lies between the tooth and the bone. Besides holding teeth in place through tiny attached fibers, the ligament also allows the teeth to move in tiny increments.
Braces’ wires laced through brackets affixed to the teeth exert pressure on them in the desired direction of movement –the periodontal ligament and other structures do the rest. To maintain that pressure we need to attach them to an “anchor”—in basic malocclusions that’s usually the back molar teeth.
But not all malocclusions are that simple. Some may require moving only certain teeth while not moving their neighbors. Younger patients’ jaws and facial structures still under development may also need to be considered during orthodontic treatment. That’s why orthodontists have other anchorage methods to address these possible complications.
One example of an alternate anchorage is a headgear appliance that actually uses the patient’s skull as the anchor. The headgear consists of a strap running around the back of the head and attached in front to orthodontic brackets (usually on molar teeth). The pressure it exerts can trigger tooth movement, but it can also help influence jaw development if an upper or lower jaw is growing too far forward or back.
Another useful anchorage method is a tiny metal screw called a temporary anchorage device (TAD) that is implanted into the jawbone above the teeth through the gums. Orthodontists then attach elastic bands between implanted TADs and specific braces’ brackets or wires to exert pressure on certain teeth but not others with pinpoint accuracy. After treatment the TADs can be easily removed.
Using these and other appliances allows orthodontists to customize treatment to an individual patient’s particular malocclusion. With the right anchor, even the most complex bite problem can be transformed into a beautiful and healthy smile.
