Periodontal (gum) disease is a bacterial infection, which if left untreated could cause gum recession, bone loss and eventually tooth loss. Caused mainly by plaque left on tooth surfaces from poor hygiene practices, the deeper the infection spreads below the gum line, the more difficult it is to treat.
One possible scenario involves parts of a tooth’s root structure known as furcations. These are branching forks formed during the early development of teeth with multiple roots where they take different paths from the base of the crown. As gum disease spreads around the root it may cause different degrees of bone loss at the point of the branch.
It’s imperative when treating gum disease to uncover and remove any bacterial plaque or calculus (hardened plaque deposits) found, including below the gum line. To address bacterial plaque at the root level, it’s important to first determine if bone loss has involved the furcations (where the roots separate, also referred to as a “furcation invasion”) and to what degree.
We usually classify this degree of involvement in three classes: Class I, the invasion has created a groove in the furcation, but minimal significant bone loss; Class II, the bone loss has extended into the furcation by at least two millimeters; or Class III, the bone loss extends completely from one end of the furcation to the other (or “through and through”).
Depending on the class, cleaning plaque and calculus from furcations and then maintaining them thereafter can be quite challenging. We may need to use specially shaped hand instruments known as scalers or curettes to reach and clean root surfaces, or ultrasonic scalers that use high-frequency vibrations and streaming water to loosen and flush away plaque debris. It may also prove helpful, though limited, to apply antimicrobials or antibiotics to the area to help limit the levels of bacteria.
Disease damage around furcations may also require surgical treatment to encourage new tissue and bone growth in the area. Surgery can also help make the area more accessible to future cleaning and maintenance, both for you and us. Renewed hygiene practices on your part and regular cleaning and checkups with us will help ensure that the situation involving your tooth roots can be kept under control and your tooth preserved for many years to come.
In her decades-long career, renowned actress Kathy Bates has won Golden Globes, Emmys, and many other honors. Bates began acting in her twenties, but didn't achieve national recognition until she won the best actress Oscar for Misery — when she was 42 years old! “I was told early on that because of my physique and my look, I'd probably blossom more in my middle age,” she recently told Dear Doctor magazine. “[That] has certainly been true.” So if there's one lesson we can take from her success, it might be that persistence pays off.
When it comes to her smile, Kathy also recognizes the value of persistence. Now 67, the veteran actress had orthodontic treatment in her 50's to straighten her teeth. Yet she is still conscientious about wearing her retainer. “I wear a retainer every night,” she said. “I got lazy about it once, and then it was very difficult to put the retainer back in. So I was aware that the teeth really do move.”
Indeed they do. In fact, the ability to move teeth is what makes orthodontic treatment work. By applying consistent and gentle forces, the teeth can be shifted into better positions in the smile. That's called the active stage of orthodontic treatment. Once that stage is over, another begins: the retention stage. The purpose of retention is to keep that straightened smile looking as good as it did when the braces came off. And that's where the retainer comes in.
There are several different kinds of retainers, but all have the same purpose: To hold the teeth in their new positions and keep them from shifting back to where they were. We sometimes say teeth have a “memory” — not literally, but in the sense that if left alone, teeth tend to migrate back to their former locations. And if you've worn orthodontic appliances, like braces or aligners, that means right back where you started before treatment.
By holding the teeth in place, retainers help stabilize them in their new positions. They allow new bone and ligaments to re-form and mature around them, and give the gums time to remodel themselves. This process can take months to years to be complete. But you may not need to wear a retainer all the time: Often, removable retainers are worn 24 hours a day at first; later they are worn only at night. We will let you know what's best in your individual situation.
So take a tip from Kathy Bates, star of the hit TV series American Horror Story, and wear your retainer as instructed. That's the best way to keep your straight new smile from changing back to the way it was — and to keep a bad dream from coming true.
