Dental implants do much more than just improve your appearance. Dr. Angela Toy, your Newberg, OR dentist at Arbor Hills Dental, dental implantsshares information on several long-term benefits of dental implants.

Dental implants save you money in the long-run

Dental implants may seem a little expensive initially, but if you compare the lifetime cost of implants to those of bridges or dentures, you will probably discover that implants are the most cost effective choice. Because implants actually become part of your jawbone, you'll probably never need to replace them. Dentures and bridges eventually wear out and may need to be replaced multiple times.

Implants prevent additional tooth loss

Jawbone loss is an unfortunate consequence after you lose a tooth. Without the tooth root to provide stimulation, the area of the bone underneath the missing tooth begins to recede. As the years go by, bone loss can worsen, particularly if you've lost more than one tooth. A shrinking jawbone can lead to facial sagging and even cause additional bone loss if it becomes so weak that it can't adequately support your teeth. Since dental implants permanently replace your roots, they offer the same strengthening benefits for your jawbone.

Dental implants can prevent shifting teeth

After the loss of a tooth, nearby teeth gradually begin to shift toward the opening. Drifting teeth can cause:

  • Cosmetic Issues: When your previous straight teeth begin to overlap, you may feel self-conscious about your smile.
  • Bite Problems: Bite problems occur when your teeth don't fit together perfectly. These issues can cause enamel erosion, jaw pain, difficulty chewing and headaches.
  • Oral Hygiene Issues: Overlapping teeth are more difficult to clean. If toothbrush bristles or floss can't reach those areas, plaque and tartar can build up and cause tooth decay. When you choose a dental implant, you won't have to worry about shifting teeth and all of the problems that can occur.

Dental implants are an excellent long-term tooth replacement option. If you're interested in learning more about implants, call Dr. Angela Toy, your Newberg, OR dentist at Arbor Hills Dental at (503) 538-2143.


A few days before the Oscars, Vanity Fair magazine asked Academy Awards host Neil Patrick Harris to name his most treasured possession. Was it his Tony award statuette for best leading actor in a musical? His star on the Hollywood Walk of Fame? The stethoscope he wore while playing teenaged doctor Doogie Howser on TV? No, as it turns out, the 41-year-old actor’s most treasured possession is… his wisdom teeth. Yes, you read that correctly. “Oddly, I still have my four wisdom teeth,” Harris said. “I refuse to let them go or I’ll lose my wise parts.”

How odd is it for a 41-year-old to have wisdom teeth? Actually, not that odd at all. While it is true that wisdom teeth are often removed, there’s no one-size-fits-all approach to this. It all depends on whether they are causing problems now, or are likely to cause problems in the future.

The trouble wisdom teeth cause is related to the fact that they are the last molars to come in, and that molars are large in size. By the time wisdom teeth appear between the ages of 17 and 21, there often is not enough room for them in the jaw. Sometimes it’s because you may have inherited a jaw size that’s too small for your tooth size; and generally speaking, the size of the human jaw has evolved to become smaller over time.

If room is lacking, the adjacent molar (that came in earlier) can interfere with the path of eruption — causing the wisdom tooth to come in at an odd angle. The wisdom tooth can hit up against that other tooth, possibly causing pain or damaging the adjacent tooth. This is known as “impaction.” Sometimes the wisdom tooth breaks only partway through the gum tissue, leaving a space beneath the gum line that’s almost impossible to clean, causing infection. A serious oral infection can jeopardize the survival of teeth, and even spread to other parts of the body.

If a wisdom tooth is impacted, will you know it? Not necessarily. A tooth can be impacted without causing pain. But we can see the position of your wisdom teeth on a dental x-ray and help you make an informed decision as to whether they should stay or go. If removal is the best course of action, rest assured that this procedure is completely routine and that your comfort and safety is our highest priority. If there is no great risk to keeping them, as Neil Patrick Harris has done, we can simply continue to monitor their condition at your regular dental checkups. It will be particularly important to make sure you are reaching those teeth with your brush and floss, and that you keep to your schedule of regular professional cleanings at the dental office. All healthy teeth are indeed worth treasuring.

Periodontal (gum) disease is a serious infection that can damage more than periodontal tissues — supporting bone structure is also at risk. Any bone loss could eventually lead to tooth loss.

To stop it from causing this kind of damage, we must match this disease's aggressiveness with equally aggressive treatment. The various treatment techniques all have the same goal: to remove bacterial plaque, the source of the infection, from all oral surfaces, including below the gum line. Buildup of plaque, a thin film of food particles, after only a few days without adequate brushing and flossing is enough time to trigger gum disease.

The basic removal technique is called scaling, using hand instruments called scalers to manually remove plaque and calculus (hardened plaque deposits) above or just below the gum line. If the disease or infection has advanced to the roots, we may use another technique called root planing in which we shave or “plane” plaque and tartar from the root surfaces.

Advancing gum disease also causes a number of complex problems like abscesses (localized infections in certain areas of gum tissue) or periodontal pockets. In the latter circumstance the slight normal gap between tooth and gums becomes deeper as the tissues weaken and pull away. This forms a void or pocket that fills with inflammation or infection that must be removed. Plaque buildup can also occur around furcations, the places where a tooth's roots divide off from one another.

It may be necessary in these more complex situations to perform a procedure known as flap surgery to gain access to these infected areas. As the name implies, we create an opening in the gums with a hinge, much like the flap of a paper envelope. Once the accessed area has been cleansed of plaque and infected tissues (and often treated with antibiotics to stop further infection), the flapped tissue is closed back in place and sutured.

To avoid these advanced stages it's important for you to see us at the first sign of problems: swollen, red or bleeding gums. Even more important is to reduce your risk for gum disease in the first place with dedicated daily brushing and flossing to remove plaque and regular dental visits for more thorough cleaning.

Gum disease can be devastating to your long-term dental health. But with diligent hygiene and early aggressive treatment you can stop this destructive disease in its tracks.
