"Debit or credit?" "Buy or rent?" "Paper or plastic?" Decisions, decisions. It's great to have more than one good option, but it can also provoke a lot of thought in making the right choice. Here's another decision you may one day have to face: "Save my tooth or replace it?"
It's hard to pass up replacing a tooth causing you misery, especially when the alternative is a functional and attractive dental implant. But before you do, consider this important message the American Association of Endodontists relay during Save Your Tooth Month in May: Before you part with a tooth, consider saving it as the best option for your oral health.
Even an implant, the closest dental prosthetic we now have to a real tooth, doesn't have all the advantages of the original. That's because your teeth, gums and supporting bone all make up an integrated oral system: Each component supports the other in dental function, and they all work together to fight disease.
Now, there are situations where a tooth is simply beyond help, and thus replacing it with an implant is the better course of action. But if a tooth isn't quite to that point, making the effort to preserve it is worth it for your long-term health.
A typical tooth in peril is one with advanced tooth decay. Decay begins when acid softens tooth enamel and creates a cavity. At this stage, we can often fill it with a tooth-colored filling. But if it isn't caught early, the decay can advance into the tooth's interior pulp, well below the enamel and dentin layers.
This is where things get dicey. As decay infects the pulp, it can move on through the root canals to infect the underlying bone. If this happens, you're well on your way to losing the tooth. But even if the pulp and root canals have become infected, we may still be able to save the tooth with root canal therapy.
Here's how it works: We first drill a tiny access hole into the infected tooth. Using special instruments, we remove all of the infected tissue from within the pulp chamber and root canals. After a bit of canal reshaping, we fill the now empty spaces with a rubber-like substance called gutta percha. After it sets, it protects the tooth from any more infection.
Contrary to what you might think, root canals aren't painful, as your tooth and the surrounding tissue are completely anesthetized. In fact, if your tooth has been hurting, a root canal will stop the pain. Better yet, it could save a tooth that would otherwise be lost—a satisfying outcome to a wise decision.

The mouth is a crowded place with nerves, blood vessels and sinus cavities sharing common space with the teeth and gums. Although important in their own right, these structures can also hinder treatment for complex dental situations like dental implant surgery or impacted teeth.
Treating these and similar situations depends on getting an accurate depiction of “what lies beneath.” Conventional x-rays help, but their two-dimensional images don't always give the full picture. There's another way—cone beam computed tomography (CBCT).
Similar to CT scanning, CBCT uses x-ray energy to take hundreds of “sliced” images that are then re-assembled with special software to create a three-dimensional model viewable on a computer screen. CBCT is different, though, in that it employs a scanning device that revolves around a patient's head, which emits a cone-shaped beam of x-rays to capture the images.
A dentist can manipulate the resulting 3-D model on screen to study revealed oral structures from various angles to pinpoint potential obstacles like nerves or blood vessels. The detailed model may also aid in uncovering the underlying causes of a jaw joint disorder or sleep apnea.
CT technology isn't the only advanced imaging system used in healthcare. Another is magnetic resonance imaging (MRI), which excites hydrogen atoms in water molecules. This produces different vibration rates in individual tissue structures, which are then translated into detailed images of these structures. Unlike CT or CBCT, MRI doesn't use x-ray energy, but rather a magnetic field and radio waves to produce the atomic vibrations.
But while providing good detail of soft tissues, MRI imaging doesn't perform as well as CBCT with harder tissues like bone or teeth. As to the potential risks of CBCT involving x-ray radiation exposure, dentists follow much the same safety protocols as they do with conventional x-rays. As such, they utilize CBCT only when the benefits far outweigh the potential x-ray exposure risks.
And, CBCT won't be replacing conventional x-rays any time soon—the older technology is often the more practical diagnostic tool for less invasive dental situations. But when a situation requires the most detailed and comprehensive image possible, CBCT can make a big difference.

In any given year, 4 million tweens and teens are in the process of having their teeth straightened with braces or clear aligners. It's so common we tend to consider orthodontic treatment for young people as a rite of passage into adulthood.
But it doesn't necessarily have to be that way—it might be possible to stop or at least minimize a poor bite before it fully develops. That's the goal of interceptive orthodontics—treatments that head off or “intercept” a bite problem early.
The goal isn't necessarily to reposition misaligned teeth, but to correct a problem that can lead to misalignment. Here are some examples.
A narrow jaw. A narrowly developing jaw can crowd incoming teeth out of their normal positions. For the upper jaw, though, we can take advantage of a temporary separation in the bones in the roof of the mouth (palate) with a device called a palatal expander. Placed against the palate, the expander exerts outward pressure on the teeth and jaw to widen this separation. The body fills in the gap with bone to gradually widen the jaw.
Abnormal jaw alignment. It's possible for a jaw to develop abnormally during childhood so that it extends too far beyond the other. Using a hinged device called a Herbst appliance, it's possible to interrupt this abnormal growth pattern and influence the bones and muscles of the jaw to grow in a different way.
Missing primary teeth. An important role for a primary (baby) tooth is to hold a place for the future permanent tooth. But if the primary tooth is lost too soon, other teeth can drift into the space and crowd out the intended permanent tooth. To prevent this, we can insert a space maintainer: This simple looped metal device prevents teeth from drifting and preserves the space for the permanent tooth.
Although these and other interceptive treatments are effective, some like the palatal expander do their best work within a limited age frame. To take advantage of interceptive orthodontics in a timely manner, parents should seek a bite evaluation for their child from an orthodontist around age 6. The earlier we detect a growing bite problem, the greater your chances for successful intervention.

For nearly two decades, singer-songwriter Taylor Swift has dominated the pop and country charts. In December she launched her ninth studio album, called evermore, and in January she delighted fans by releasing two bonus tracks. And although her immense fame earns her plenty of celebrity gossip coverage, she's managed to avoid scandals that plague other superstars. She did, however, run into a bit of trouble a few years ago—and there's video to prove it. It seems Taylor once had a bad habit of losing her orthodontic retainer on the road.
She's not alone! Anyone who's had to wear a retainer knows how easy it is to misplace one. No, you won't need rehab—although you might get a mild scolding from your dentist like Taylor did in her tongue-in-cheek YouTube video. You do, though, face a bigger problem if you don't replace it: Not wearing a retainer could undo all the time and effort it took to acquire that straight, beautiful smile. That's because the same natural mechanism that makes moving teeth orthodontically possible can also work in reverse once the braces or clear aligners are removed and no longer exerting pressure on the teeth. Without that pressure, the ligaments that hold your teeth in place can “remember” where the teeth were originally and gradually move them back.
A retainer prevents this by applying just enough pressure to keep or “retain” the teeth in their new position. And it's really not the end of the world if you lose or break your retainer. You can have it replaced with a new one, but that's an unwelcome, added expense.
You do have another option other than the removable (and easily misplaced) kind: a bonded retainer, a thin wire bonded to the back of the teeth. You can't lose it because it's always with you—fixed in place until the orthodontist removes it. And because it's hidden behind the teeth, no one but you and your orthodontist need to know you're wearing it—something you can't always say about a removable one.
Bonded retainers do have a few disadvantages. The wire can feel odd to your tongue and may take a little time to get used to it. It can make flossing difficult, which can increase the risk of dental disease. However, interdental floss picks can help here. And although you can't lose it, a bonded retainer can break if it encounters too much biting force—although that's rare.
Your choice of bonded or removable retainer depends mainly on your individual situation and what your orthodontist recommends. But, if losing a retainer is a concern, a bonded retainer may be the way to go. And take if from Taylor: It's better to keep your retainer than to lose it.

Millions of Americans have had a root canal. The procedure is an endodontic treatment to remove the inner pulp and nerves from an infected tooth. The infection can be caused by injury or tooth decay. Dr. Colin L. Smith is a dentist at Lake Oswego Smiles. He practices general and cosmetic dentistry.
Signs You May Need a Root Canal
Lake Oswego residents may need a root canal if they are experiencing one or more of the following symptoms:
- Throbbing tooth pain
- Tooth sensitivity to hot and cold temperatures
- A tooth that is tender to the touch or when chewing
- Swollen gum around the tooth
- Tender lymph nodes
What Happens During a Root Canal?
After taking X-rays, Dr. Smith will isolate the affected tooth with a dental damp to keep it clean and dry. He will then drill a hole through the tooth’s crown to access the infected pulp. He will then clean out the chamber of the tooth and prepare it for filling. After the tooth has been filled, Dr. Smith will cement a prosthetic crown to the tooth to strengthen it. You may feel a little discomfort over the next few days, but you can take over-the-counter pain killers to relive this.
You should return to Dr. Smith if you experience any of the following after a root canal:
- Severe pain for more than three days
- Visible swelling on the inside or outside of your mouth
- A rash or itching
- Your bite doesn’t feel normal
- The crown becomes loose or falls off
In some cases you may have an infected tooth without noticing any symptoms, this is why it’s a good idea to have a regular six-month check-up so the dentist can spot the early signs of any oral issues and stop them from worsening.
If you live in Lake Oswego and you are looking for a dentist or you would like to find out more about having a root canal, call Dr. Smith at (503) 635-3653.
