All crowns are designed to restore functionality to a damaged tooth. But crowns can differ from one another in their appearance, in the material they’re made from, and how they blend with other teeth.
A crown is a metal or porcelain artifice that’s bonded permanently over a decayed or damaged tooth. Every crown process begins with preparation of the tooth so the crown will fit over it. Afterward, we make an impression of the prepared tooth digitally or with an elastic material that most often is sent to a dental laboratory to create the new crown.
It’s at this point where crown composition and design can diverge. Most of the first known crowns were made of metal (usually gold or silver), which is still a component in some crowns today. A few decades ago dental porcelain, a form of ceramic that could provide a tooth-like appearance, began to emerge as a crown material. The first types of porcelain could match a real tooth’s color or texture, but were brittle and didn’t hold up well to biting forces. Dentists developed a crown with a metal interior for strength and a fused outside layer of porcelain for appearance.
This hybrid became the crown design of choice up until the last decade. It is being overtaken, though, by all-ceramic crowns made with new forms of more durable porcelain, some strengthened with a material known as Lucite. Today, only about 40% of crowns installed annually are the metal-porcelain hybrid, while all-porcelain crowns are growing in popularity.
Of course, these newer porcelain crowns and the attention to the artistic detail they require are often more expensive than more traditional crowns. If you depend on dental insurance to help with your dental care costs, you may find your policy maximum benefit for these newer type crowns won’t cover the costs.
If you want the most affordable price and are satisfied primarily with restored function, a basic crown is still a viable choice. If, however, you would like a crown that does the most for your smile, you may want to consider one with newer, stronger porcelain and made with greater artistic detail by the dental technician. In either case, the crown you receive will restore lost function and provide some degree of improvement to the appearance of a damaged tooth.
National Fresh Breath Day is celebrated in August, but who doesn’t want fresh breath every day? Everyone has bad breath once in a while, so here are some tips to fight it.
1. Step up your oral hygiene routine.
Good oral hygiene is the first line of defense against bad breath. Brush your teeth morning and night and floss daily to remove much of the tiny food debris and plaque (colonies of oral bacteria) that can cause bad breath.
2. Don’t neglect your tongue.
A coated tongue can be a source of bad breath, so brush your tongue as well as your teeth or use a tongue scraper, which can be purchased in the oral health aisle of your local pharmacy.
3. Clean around your braces.
If you have braces, use an interdental brush or a water flosser to free trapped food particles.
4. Pay attention to your oral appliances.
If you wear dentures, be sure to clean them thoroughly every day, and brush your gums and the inside of your mouth as well. Bridgework also needs special attention: Clean carefully around the bridge and under the false tooth, as food can get stuck there.
5. Tackle dry mouth.
Dry mouth, a major cause of bad breath, can result from numerous medications, salivary gland problems, or breathing through the mouth instead of the nose due to sinus problems, sleep apnea, or other conditions. If your mouth is chronically dry, chew sugarless gum to stimulate saliva production, or ask about an over-the-counter or prescription saliva substitute.
6. Avoid extreme dieting.
Weight loss diets that advocate a stringent reduction in carbohydrates can lead to “keto breath.” This foul-smelling breath happens when the body burns fat instead of glucose for fuel.
7. Quit smoking.
In addition to smelling like cigarettes, people who smoke have less—as well as lower quality—saliva, which contributes to bad breath and poor oral health. If you need help quitting, talk with us or call (800) QUIT-NOW.
8. Be aware that some foods and beverages can leave stinky breath.
These include garlic, onions, strong spices, coffee, alcohol, cheese, and canned fish.
9. Keep up with regular dental visits.
Professional dental cleanings are necessary to get rid of hardened plaque (tartar) that can’t be removed by your brushing and flossing routine at home. We also check for gum disease, another cause of bad breath.
10. See your doctor.
Certain medical conditions like acid reflux, diabetes, and respiratory infections can cause bad breath. If you have an untreated health condition, make an appointment with your medical doctor.

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.”
Barley malt, corn syrup, maltodextrin — these and over fifty other label ingredients are all names for refined sugar. Under its various aliases, this sweet carbohydrate is tucked away in three-quarters of packaged foods in the U.S.
Although in recent years the general health effects from too much sugar have gained the spotlight, its effect on dental health has been known for decades. Accumulated sugar in the mouth is a prime food source for bacteria that cause tooth decay and gum disease.
For both general and oral health, people have been looking to artificial alternatives to satisfy their sweet tooth. But do they have their own issues that can impact overall health? Here is an overview of some of the more popular brands of artificial sweeteners and their effect on health.
Saccharin — One of the most widely used artificial sweeteners, saccharin is often used under the names Sweet’N Low or Sugar Twin in low-calorie foods because it contains no calories. According to the Food and Drug Administration (FDA) there are no associated health risks with consuming saccharin in recommended servings.
Aspartame — used commonly in beverages as Equal or NutraSweet, aspartame is unsuitable for cooking because its chemical structure breaks down under high heat. Although generally safe for consumption, it can affect people with a rare condition known as phenylketonuria that can’t adequately break down its chemicals.
Sucralose — marketed as Splenda, this sweetener is made by chemically altering refined table sugar so the body can’t process it. This may be one reason it has the most recognized natural flavor profile among consumers and is a market leader. It’s stable at high temperatures, so it’s often used in cooked or baked goods.
Stevia/Erythritol — this combination of an extract from the extremely sweet herb stevia and the sugar alcohol erythritol is marketed as Truvia. Unlike other calorie-free artificial sweeteners, this and other alcohol-based sweeteners have a low calorie level due to sugar alcohol’s characteristic of slow and incomplete absorption during digestion.
Xylitol — although all the previously mentioned sweeteners won’t promote bacterial growth like refined sugar, the sugar alcohol xylitol — often added to chewing gum and mints — has an added benefit: it may actually reduce levels of bacteria most likely to cause decay.

A critical part of effective, daily oral hygiene, flossing removes bacterial plaque from between teeth that can’t be accessed with brushing. Unfortunately, it’s often neglected — string flossing requires a bit more dexterity than brushing and can be difficult to do properly.
It can be even more difficult for people with implants or who wear orthodontic appliances. For brace wearers in particular, getting access to areas between teeth with string floss is next to impossible; the metal brackets and tension wire also have a tendency to catch and retain food debris that’s difficult to remove with brushing alone.
Water flossing, using a device called an oral irrigator, is an effective alternative that addresses many of these difficulties. First available for home use in the 1960s, an oral irrigator delivers pulsating water at high pressure through a handheld applicator that forcefully flushes material from between teeth.
There’s no question that string flossing is effective in plaque removal between teeth — but what about oral irrigators? A 2008 study looked at a group of orthodontic patients with braces who used oral irrigators and compared them with a similar group that only brushed. The study found that five times as much plaque was removed in the group using the oral irrigators as opposed to the group only brushing.
Oral irrigators may also be effective for people who’ve developed periodontal (gum) disease. In fact, oral irrigators coupled with ultra-sound devices are routinely used by dental hygienists to remove plaque and calculus (hardened plaque deposits) in periodontal patients. As with regular oral hygiene, though, it’s important for patients with gum disease to include water flossing with daily brushing (at least twice a day) and regular cleaning sessions at the dentist to ensure removal of all plaque and calculus.
If you’re interested in using an oral irrigator, be sure to consult with us at your next appointment. Not only can we recommend features to look for in equipment, but we can also instruct you on the techniques to make water flossing an effective plaque remover.
