If you've known anyone who has worn braces, you know what comes after — wearing a retainer. This can be kind of a letdown after all those months with braces, but it's absolutely necessary.
That's because teeth have a tendency to “rebound” to their pre-orthodontic positions once the force to move them stops after the braces are removed. Retainers help keep or “retain” moved teeth in their new positions and prevent them from reverting to the old.
When you think “retainer,” you probably picture a removable appliance with a wire that fits over the front of the teeth. While that may be the most common type, it isn't the only one. There's another called a bonded retainer, a thin piece of wire bonded to the back of the teeth that need to be retained. Unlike the other type, a dentist must remove a bonded retainer when it's no longer needed.
The biggest advantage of a bonded retainer is its invisibility — the wire is behind the teeth so no one can see it as with a removable retainer. The wire is bonded to the teeth with a dental composite material and then light-cured to create a strong attachment.
Another advantage is especially pertinent to younger patients. Because it's permanently attached and can't be taken out, there's no constant reminding of the patient to wear it — and no more worries about replacing a lost one.
They can, though, be difficult to floss around leading to potential plaque buildup that increases disease risk. It's very important you receive proper hygiene instruction for cleaning under the bonded retainer. Another concern is that they can break under excessive chewing pressure. And as with the more common retainer, we wouldn't want to remove it as that will result in the teeth's relapse to their old positions.
To learn which retainer is best for your situation, you should discuss the options with your orthodontist. Regardless of which type you choose, though, a retainer is a must for protecting your investment in that new smile.

It’s been a long road back to oral health for you after periodontal (gum) disease. But after several plaque removal sessions and perhaps even surgical procedures to address deep infection, your gums have regained their healthy pink appearance.
But now you must face a hard reality: because you’ve had gum disease you’ll need to be extra vigilant with your oral hygiene to avoid another round with this destructive disease. But don’t worry—you won’t have to fight your prevention battle alone. We’ll continue to provide you care that reduces your risk of re-infection. We call that care periodontal maintenance (PM).
The heart of PM care involves regular dental visits for monitoring, cleanings and treatment when necessary. While most patients may visit their dentist at least twice a year, as a previous gum disease patient we may advise more frequent visits, especially if you’ve just finished periodontal treatment. Depending on the extent of your disease, we may begin with a visit every other week or once every two to three months. If your mouth continues to be disease-free we may suggest increasing the time between visits.
During your visit we’ll carefully examine your mouth, as well as screen you for any signs of potential oral cancer. We’re looking for both signs of re-infection or new issues with your teeth and gums. We’ll also assess the effectiveness of your oral hygiene efforts and advise you on ways you can improve.
If we find any signs of disease, we’ll then formulate a treatment plan to effectively deal with it. With frequent visits we have a better chance of discovering re-infection early—and the earlier the better to minimize any further damage. We may also need to take steps to make future PM care easier. This could include gum surgery to alter the tissues around certain teeth for easier access for examination and cleaning.
Our main focus with PM care is to look ahead: what can we do now to prevent a future bout of gum disease or at least lessen its effect? With continued monitoring and care we can drastically reduce your risk for further damage from this destructive disease.

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.
