After months of wearing braces, the big day has arrived — they’re finally off! Your teeth have been realigned and your smile is dazzling. You’re finished with orthodontic treatment, right?
Not quite — because if you want to keep your new smile you have one more treatment phase to go — wearing a retainer. Without this phase there’s a distinct possibility you could lose all the time, effort and expense of braces because your teeth could revert to their previous position.
To understand why, we have to consider how teeth can move in the first place. Although it may seem like your teeth are rigidly fastened to the jawbone, they’re actually held in place by the periodontal ligament, a strong, elastic gum tissue that lies between the teeth and the bone. Tiny fibers from the ligament attach to the teeth on one side and to the bone in a similar manner on the other side.
When pressure is applied to the tooth as happens with braces, the bone around the side of the tooth in the direction of the force will begin to dissolve (resorb), allowing the tooth to move in that direction. New bone will then build up on the other side to stabilize the tooth. Once the pressure is removed (when we take the braces off), there’s a tendency for the teeth, bone and gums to “remember” the old position and try to revert back.
The answer is a removable mouth appliance known as a retainer. Custom-designed to fit the teeth’s new position, the retainer helps hold the teeth in place until the bone completely sets around them. In the beginning, you may need to wear the retainer around the clock and then later only at night while you sleep. While you may only need to wear it for a few months (especially if you’re an adolescent or young adult) some patients may need to wear some form of retainer indefinitely. Your orthodontist will advise you how long depending on your individual situation.
While retainers may seem like an inconvenience, they’re extremely important for keeping or “retaining” the teeth in their new and better position. Following through on this important phase of treatment will help ensure you’ll keep your new smile for a long time to come.

Periodontal disease may start in the gums’ superficial layers, but it’s not likely to stay there. As the disease moves deeper it can wreak havoc on tooth roots and bone as well as gum tissue attachments. Teeth with multiple roots are in particular peril because of the “forks” called furcations that form where the roots separate from each other. Infected furcations can be very difficult to treat.
We primarily treat gum disease by removing its main source, a thin film of bacteria and food particles called dental plaque that builds up on teeth. To remove it we most often use special hand tools or ultrasonic equipment to vibrate it loose. As the plaque and tartar diminish, the infection begins to wane.
But we can’t be completely successful in stopping the disease if any lingering plaque deposits remain. This especially includes furcations where the infection can cause significant damage to the roots. Although cleaning furcations of plaque can be difficult, it’s not impossible with the aforementioned tools and antimicrobial substances to disinfect the area.
The real problem, though, is access—effectively getting to the furcations to treat them. We may need to perform a surgical procedure called flap surgery where we create a hinged flap in the gum tissue to move it aside and access the root area beneath. Afterward we replace the flap and suture the tissue back in place.
In some cases, the infection may have already caused significant damage to the tissue and underlying bone. We may therefore need to graft gum or bone tissues to these damaged areas to stimulate re-growth. We may also need to surgically reshape the gum attachments around a tooth to make it easier in the future to access and clean the area.
These additional treatments around furcations can be very involved and labor-intensive. That’s why the best outcomes occur if we’re able to start treatment in the early stages of an infection. So, if you notice red, swollen or bleeding gums contact your dentist as soon as possible. Treating gum disease as early as possible will help ensure your tooth roots won’t suffer extensive damage.

Cancer treatment can be an all-out battle with intense side effects for your entire body. One particular area that can suffer is your mouth.
Chemotherapy and radiation target and destroy cancer cells, which can lead to non-cancerous cells caught in the crossfire and also destroyed. The salivary glands in the mouth are prone to such damage, which could greatly impact your ability to ward off dental disease.
Saliva, what salivary glands produce, plays a major role in oral health. The bodily fluid disseminates antibodies throughout the mouth that fight disease-causing bacteria. It also neutralizes acid, which can erode tooth enamel, and helps restore lost minerals to the enamel.
If the salivary glands become damaged, however, they may produce less saliva and create a condition called xerostomia or “dry mouth.” This is a common occurrence for cancer patients, which can rob them of saliva’s benefits and make them more susceptible to tooth decay or periodontal (gum) disease. The end result could be tooth loss.
There are things you and your dentist can do to prevent this. First, have a complete dental checkup before undergoing cancer treatment. If at all possible have any necessary dental work undertaken (with adequate recovery time afterward) before beginning chemo or radiation. Your dentist and oncologist (cancer specialist) may need to coordinate any planned dental work.
You should also practice daily oral hygiene with brushing and flossing, along with keeping up your regular dental cleanings. This will prevent the buildup on teeth of bacterial plaque, which in turn will reduce your chances for dental disease. Your dentist may also prescribe antibacterial as well as fluoride mouth rinses to help limit the growth of oral bacteria.
To minimize dry mouth, increase your water consumption as much as possible. You may also use saliva boosters like xylitol, an alcohol-based sweetener found in many gums or mints that promotes salivation (it also deters oral bacterial growth).
And don’t forget to maintain a healthy diet, which will not only benefit your stamina during cancer treatment but can also help you maintain better dental health. Providing good care for your mouth during this trying time will help ensure your teeth and gums stay as healthy as possible.
