Dental crowns are an essential means for restoring damaged or unattractive teeth. A well-crafted crown not only functions well, it looks and blends seamlessly with the rest of the natural teeth.
Crowns are artificial caps that cover an entire visible tooth, often used for heavily decayed or damaged teeth or as added protection after a root canal treatment. Most crowns are produced by a dental lab, but some dentists are now creating them in-office with computer-based milling equipment. On the whole, the various crowns now available function adequately as teeth—but they can vary in their appearance quality.
In the early to mid 20th Century the all-metal crown was the standard; but while durable, it could be less than eye-pleasing. Although more life-like dental porcelain existed at the time, it tended to be brittle and could easily shatter under chewing stress.
Dentists then developed a crown that combined the strength of metal with the attractiveness of porcelain: the porcelain fused to metal or PFM crown. The PFM crown had a hollow, metal substructure that was cemented over the tooth. To this metal base was fused an outer shell of porcelain that gave the crown an attractive finish.
The PFM reigned as the most widely used crown until the mid 2000s. By then improved forms of porcelain reinforced with stronger materials like Lucite had made possible an all-ceramic crown. They’re now the most common crown used today, beautifully life-like yet durable without the need for a metal base.
All-ceramics may be the most common type of crown installed today, but past favorites’ metal and PFM are still available and sometimes used. So depending on the type and location of the tooth and your own expectations, there’s a right crown for you.
However, not all crowns even among all-ceramic have the same level of aesthetic quality or cost—the more life-like, the more expensive. If you have dental insurance, your plan’s benefits might be based on a utilitarian but less attractive crown. You may have to pay more out of pocket for the crown you and your dentist believe is best for you.
Whatever you choose, though, your modern dental crown will do an admirable, functional job. And it can certainly improve your natural tooth’s appearance.
Ah, the baby teeth: those cute little pearl buttons that start to appear in a child’s mouth at around 6 to 9 months of age. Like pacifiers and bedtime stories, they’ll be gone before you know it — the last usually disappear by age 10-13. So if the dentist tells you that your young child needs a root canal, you might wonder why — isn’t that tooth going to be lost anyway?
The answer is yes, it is — but while it’s here, it has some important roles to play in your child’s development. For one thing, baby teeth perform the same functions in kids as they do in adults: Namely, they enable us to chew, bite, and speak properly. The primary teeth also have a valuable social purpose: they allow us to smile properly. If a baby tooth is lost prematurely at age 6, the child may suffer detrimental effects for five years or more — and that’s a long time for someone so young!
Even more important, baby teeth have a critical function in the developing mouth and jaw: Each one holds a space open for the permanent tooth that will eventually replace it — and it doesn’t “let go” until the new tooth is ready to come in. If a primary (baby) tooth is lost too soon, other teeth adjacent to the opening may drift into the empty space. This often means that the permanent teeth may erupt (emerge above the gum line) in the wrong place — or sometimes, not at all.
The condition that occurs when teeth aren’t in their proper positions is called malocclusion (“mal” – bad; “occlusion” – bite). It can cause problems with eating and speaking, and often results in a less-than-perfect-looking smile. It’s the primary reason why kids get orthodontic treatment — which can be expensive and time-consuming. So it makes sense to try and save baby teeth whenever possible.
Procedures like a root canal — or the similar but less-invasive pulpotomy — are often effective at preserving a baby tooth that would otherwise be lost. But if it isn’t possible to save the tooth, an appliance called a space maintainer may help. This is a small metal appliance that is attached to one tooth; its purpose is to keep a space open where the permanent tooth can come in.
If your child is facing the premature loss of a primary tooth, we will be sure to discuss all the options with you. It may turn out that preserving the tooth is the most cost-effective alternative in the long run. If you have questions about your child’s baby teeth, please contact us or schedule an appointment for a consultation.
One of the best and most successful tooth replacement choices available is the dental implant. No other restorative method is as similar in both form and function to a real tooth as an implant; and with a success rate of 95-plus percent after ten years, it’s one of the most durable.
But there can be extenuating circumstances that make obtaining an implant difficult or sometimes impossible. One possible problematic situation is the systemic disease diabetes.
Diabetes is a hormonal condition in which the body is unable to sufficiently regulate the amount of glucose (a basic sugar that provides energy to the body’s cells) within the blood stream. Normally, the pancreas produces the hormone insulin to reduce excess glucose. But diabetes interferes with this insulin production: if you have Type 1 diabetes, the pancreas has stopped producing insulin altogether; if you have the more common Type 2, the body doesn’t produce adequate insulin or it doesn’t respond sufficiently to the insulin produced.
Over time diabetes can affect other areas of health, especially wound healing. Because the condition gradually causes blood vessels to narrow and stiffen, the normal inflammatory response to disease or trauma can become prolonged. This in turn slows the rate of wound healing.
Slow wound healing can have a bearing on the recovery period just after implant surgery, especially the necessary integration process that takes place between the bone and the titanium metal implant that provides its signature strength. If that process is impeded by slow wound healing caused by diabetes, the risk increases dramatically for implant failure.
That’s the worst case scenario if you have diabetes, but only if your condition is out of control. If, however, you have your blood sugar levels well regulated through medication, diet and exercise, then your chances for implant success could easily be on par with someone without diabetes.
So if you’re diabetic and are considering dental implants for missing teeth, it’s important to discuss the possibility of obtaining them with both your dentist and the physician caring for your diabetes. With your overall healthcare team working together, there’s no reason why diabetes should stop you from enjoying this premiere restoration for missing teeth.

On the big screen, Australian-born actress Margot Robbie may be best known for playing devil-may-care anti-heroes—like Suicide Squad member Harley Quinn and notorious figure skater Tonya Harding. But recently, a discussion of her role in Peter Rabbit proved that in real life, she’s making healthier choices. When asked whether it was hard to voice a character with a speech impediment, she revealed that she wears retainers in her mouth at night, which gives her a noticeable lisp.
“I actually have two retainers,” she explained, “one for my bottom teeth which is for grinding my teeth, and one for my top teeth which is just so my teeth don't move.”
Clearly Robbie is serious about protecting her dazzling smile. And she has good reasons for wearing both of those retainers. So first, let’s talk about retainers for teeth grinding.
Also called bruxism, teeth grinding affects around 10 percent of adults at one time or another, and is often associated with stress. If you wake up with headaches, sore teeth or irritated gums, or your sleeping partner complains of grinding noises at night, you may be suffering from nighttime teeth grinding without even being aware of it.
A type of retainer called an occlusal guard is frequently recommended to alleviate the symptoms of bruxism. Typically made of plastic, this appliance fits comfortably over your teeth and prevents them from being damaged when they rub against each other. In combination with stress reduction techniques and other conservative treatments, it’s often the best way to manage teeth grinding.
Orthodontic retainers are also well-established treatment devices. While appliances like braces or aligners cause teeth to move into better positions, retainers are designed to keep teeth from moving—helping them to stay in those positions. After active orthodontic treatment, a period of retention is needed to allow the bite to stabilize. Otherwise, the teeth can drift right back to their old locations, undoing the time and effort of orthodontic treatment.
So Robbie has the right idea there too. However, for those who don’t relish the idea of wearing a plastic appliance, it’s often possible to bond a wire retainer to the back surfaces of the teeth, where it’s invisible. No matter which kind you choose, wearing a retainer can help keep your smile looking great for many years to come.

Summer is a great time to go outdoors and get your game on—no matter whether your court is set up for tennis or basketball, whether you’re on the diamond or on the greens. Regular physical activity can help you maintain your optimal weight, reduce your risk for certain diseases, and even lower stress levels. But many of our favorite outdoor sports also carry a risk of accidental injury…and frequently this involves injuries to the mouth.
Because they’re front and center, the incisors (front teeth) are the ones most often affected by accidental injuries. While serious damage is relatively rare, chips and cracks are not uncommon. Fortunately, dentistry offers a number of good ways to restore chipped or broken teeth. Which one is best for you depends on exactly what’s wrong—but a procedure called cosmetic bonding is one of the most common ways to repair small to moderate chips where the tooth’s soft pulp isn’t exposed.
In dental bonding, a tooth-colored material is applied directly to the tooth’s surface to fill in the chip or crack. The material itself is a high-tech mixture of tough plastic resins, translucent glass-like fillers, and other substances. Strong, durable and lifelike in appearance, these composite resins can be matched to the natural shade of your teeth.
Bonding is a conservative procedure, meaning that it requires little or no preparation of the tooth. It can be done right in the dental office, often in a single visit and without the need for anesthesia. Unlike porcelain veneers or crowns (caps), it usually doesn’t involve removing significant amounts of healthy tooth structure.
While the results can last for years, bonded restorations aren’t as durable as porcelain veneers or crowns, which are made in a dental laboratory. Bonding also isn’t suitable to repair major damage, or in cases where the tooth’s pulp could become infected; in this situation, you may need a root canal and a crown. However, for moderate chips or cracks, bonding can be an appropriate and economical way to restore your teeth to full function and aesthetic appearance.
Of course, it’s often said that an ounce of prevention is worth a pound of cure. That’s why it’s best to wear a protective mouthguard whenever you’re on the field. We can provide a custom-made mouthguard that’s comfortable to wear and offers maximum protection against dental injury—just ask!
If you have questions about cosmetic bonding or mouthguards, please contact us or schedule an appointment for a consultation. You can learn more by reading the Dear Doctor magazine articles “Artistic Repair of Front Teeth with Composite Resin” and “Athletic Mouthguards.”
