Restoring chipped, stained or decayed teeth with dental porcelain is a tried and true method that’s been used for decades. In recent years, though, restorations made with composite resin have become a popular alternative.
Made of a plastic-based matrix with added glass filler, composite resin can be molded and bonded to teeth to replace missing structure with color to match. While they can’t be used for every problem situation, they’re an efficient and economical way to transform your smile.
Here are 4 advantages for using composite resin to restore moderately defective teeth.
They require very little tooth preparation. Crowns, veneers and other porcelain restorations require removing some healthy tooth structure to accommodate them. With the development of stronger bonding materials, composite resins can restore even many large defects in teeth caused by decay or trauma with little structural removal and still remain durable.
Most composite resin restorations are “single-visit” procedures. Unlike porcelain restorations, applying composite resin doesn’t require a dental lab, a process that can take multiple visits. In most cases, a skilled dentist can apply them during a single visit.
They have excellent color matching capabilities. We usually think of teeth as one single shade of white — actually, a single tooth can have varying gradations of color from the root to the tip. As mentioned before, composite resins can be prepared to match those color shades precisely, so your restored teeth look natural and blend well with your other teeth.
Composite resins can be an effective temporary fix for young injured teeth. Because children’s teeth are still developing, permanent restorations for traumatized teeth aren’t usually advisable until they’ve fully matured. Composite resin can be used to restore a young tooth’s form and function until it’s ready for a permanent solution.

One of the top concerns in public health today is exposure to the metallic element mercury within the environment. At abnormal levels, mercury can have a toxic effect on our nervous systems and cause other health problems.
These concerns over mercury have also increased attention on one material in dentistry that has included the metal in its makeup for over a century — dental amalgam for filling teeth. Amalgam is a metal alloy that can include, in addition to mercury, silver, tin, and copper. When first mixed dental amalgam is a moldable material used for fillings in prepared teeth. It then hardens into a durable restoration that can withstand biting forces.
While the use of amalgam has declined with the introduction of life-like colored fillings, it's still used for teeth like molars subject to high biting forces. With what we now know about the ill effects of mercury (which can make up to half of an amalgam mixture) is it safe to continue its use?
The American Dental Association has performed extensive research into amalgam safety. They've found that mercury is stabilized by the other metals in the amalgam. This prevents "free" molecules of mercury, the real source of harm to health, from escaping into the blood stream in the form of vapor. Although trace amounts of mercury vapor from the amalgam are released as a person chews, those levels are well below the threshold that could cause harm.
From a patient standpoint, the biggest drawback to dental amalgam isn't safety — it's the appearance of teeth it's used on. Silver fillings aren't considered attractive. And now there are viable filling alternatives that not only look like natural teeth but can withstand biting forces almost as well as amalgam. These materials include composite resins, mixtures of glass or quartz within resin, or glass and resin ionomers. Each of these has advantages and disadvantages depending on how and where they're applied.
After a thorough dental examination, we'll be able to advise you on what filling material will work best to produce the best result. And if we do suggest dental amalgam you can rest assured it will be a safe choice.

Fans of the legendary rock band Steely Dan received some sad news a few months ago: Co-founder Walter Becker died unexpectedly at the age of 67. The cause of his death was an aggressive form of esophageal cancer. This disease, which is related to oral cancer, may not get as much attention as some others. Yet Becker's name is the latest addition to the list of well-known people whose lives it has cut short—including actor Humphrey Bogart, writer Christopher Hitchens, and TV personality Richard Dawson.
As its name implies, esophageal cancer affects the esophagus: the long, hollow tube that joins the throat to the stomach. Solid and liquid foods taken into the mouth pass through this tube on their way through the digestive system. Worldwide, it is the sixth most common cause of cancer deaths.
Like oral cancer, esophageal cancer generally does not produce obvious symptoms in its early stages. As a result, by the time these diseases are discovered, both types of cancer are most often in their later stages, and often prove difficult to treat successfully. Another similarity is that dentists can play an important role in oral and esophageal cancer detection.
Many people see dentists more often than any other health care professionals—at recommended twice-yearly checkups, for example. During routine examinations, we check the mouth, tongue, neck and throat for possible signs of oral cancer. These may include lumps, swellings, discolorations, and other abnormalities—which, fortunately, are most often harmless. Other symptoms, including persistent coughing or hoarseness, difficulty swallowing, and unexplained weight loss, are common to both oral and esophageal cancer. Chest pain, worsening heartburn or indigestion and gastroesophageal reflux disease (GERD) can also alert us to the possibility of esophageal cancer.
Cancer may be a scary subject—but early detection and treatment can offer many people the best possible outcome. If you have questions about oral or esophageal cancer, call our office or schedule a consultation. You can learn more in the Dear Doctor magazine article “Oral Cancer.”
Are you doing everything you can to reduce your risk of cavities and gum disease? Even the smallest changes to your oral hygiene routine can make a significant impact on your oral health. Newberg, OR, family dentist Dr. Angela Toy of Arbor Hills Dental offers the services your family needs to keep their smiles strong and healthy.
How Can I Improve My Oral Hygiene?
Try one or more of these suggestions to enhance your usual oral hygiene routine:
- Make Consistency a Priority: You're more likely to leave a little plaque if you don't follow a consistent brushing method. Whether you begin brushing your molars first or start your brushing session with your front teeth, the order doesn't matter as long as you brush your teeth the same way every time. Flossing at the same time every day is also helpful. It's easy to forget about this oral hygiene task if it's not part of your usual hygiene routine.
- Wait to Brush: Don't brush your teeth for 30 minutes to an hour if you've just eaten an orange or other type of citrus fruit, sipped a glass of orange juice or lemonade, or downed a can of soda. Acids in these foods and beverages can soften your tooth enamel. If you brush too soon, you'll spread the acids around your mouth, increasing your cavity risk.
- Choose the Best Toothpaste and Mouthwash Options: Fluoride, a mineral added to most toothpastes, remineralizes weak areas of tooth enamel, which can help you avoid cavities and lower your risk of gum disease. You'll see the American Dental Association (ADA) seal on the box if your toothpaste contains fluoride. Mouthwash can also help you avoid cavities. Look for alcohol-free products that mention the words "anti-cavity" or "kills germs."
- Buy a Pack of Gum: Chewing sugar-free gum stimulates saliva, which helps wash away plaque.
- See the Dentist: Visiting your Newberg dentist every six months is an excellent way to protect your oral health. In addition to an examination, you'll also receive a dental cleaning that will remove plaque and tartar from your teeth and brighten your smile.
Regular dental visits are essential for good oral health. Call Newberg, OR, dentist Dr. Angela Toy of Arbor Hills Dental at (503) 538-2143 to schedule your appointment.
You’re considering dental implants and you’ve done your homework: you know they’re considered the best tooth replacements available prized for durability and life-likeness. But you do have one concern — you have a metal allergy and you’re not sure how your body will react to the implant’s titanium and other trace metals.
An allergy is the body’s defensive response against any substance (living or non-living) perceived as a threat. Allergic reactions can range from a mild rash to rare instances of death due to multiple organ system shutdowns.
A person can become allergic to anything, including metals. An estimated 17% of women and 3% of men are allergic to nickel, while 1-3% of the general population to cobalt and chromium. While most allergic reactions occur in contact with consumer products (like jewelry) or metal-based manufacturing, some occur with metal medical devices or prosthetics, including certain cardiac stents and hip or knee replacements.
There are also rare cases of swelling or rashes in reaction to metal fillings, commonly known as dental amalgam. A mix of metals — mainly mercury with traces of silver, copper and tin — dental amalgam has been used for decades with the vast majority of patients experiencing no reactions. Further, amalgam has steadily declined in use in recent years as tooth-colored composite resins have become more popular.
Which brings us to dental implants: the vast majority are made of titanium alloy. Titanium is preferred in implants not only because it’s biocompatible (it “gets along” well with the body’s immune system), but also because it’s osteophilic, having an affinity with living bone tissue that encourages bone growth around and attached to the titanium. Both of these qualities make titanium a rare trigger for allergies even for people with a known metal allergy.
Still, implant allergic reactions do occur, although in only 0.6% of all cases, or six out of a thousand patients. The best course, then, is to let us know about any metal allergies you may have (or other systemic conditions, for that matter) during our initial consultation for implants. Along with that and other information, we'll be better able to advise you on whether implants are right for you.
