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.
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.

If you suffer from a temporomandibular (“jaw joint”) pain disorder (TMD), you know any activity involving jaw movement can be uncomfortable. That includes eating.
But avoiding eating isn’t an option—which means you may be attempting to minimize discomfort during flare-ups by choosing soft, processed foods that don’t require a lot of jaw force. While this may certainly ease your TMD symptoms, you might also be cheating your health by eating foods not optimally nutritious.
It doesn’t have to be a trade-off: with a few simple techniques you can still eat whole, natural foods while minimizing jaw joint pain. Here are 3 tips for making mealtime less stressful during TMD flare-ups.
Cut food into manageable bite sizes. Preparing your food beforehand will make a big difference in how much effort your jaws exert as you eat. Make sure all your food portions of vegetables, fruits or meats are cut or prepared into small, manageable bite sizes. It also helps to remove the tough outer skin of some fruits and vegetables or to mash other foods like potatoes or beans.
Use cooking liquids to soften food. For foods that aren’t naturally moist, you can add liquids to soften them and make them easier to chew. Incorporate gravies, sauces or marinating liquids into your meal preparation to help soften tougher foods like poultry, meats or some vegetables.
Go easy with your chewing and biting motion. The strategy here is to minimize jaw movement and force as much as possible. While preparing your food as mentioned before will help a lot, how you bite and chew will also make a big difference. Limit your jaw opening to a comfortable degree, take small bites and chew slowly.
Managing a jaw joint disorder is an ongoing process. When practiced together with other treatments like therapy or medication, eating deliberately can help make life with TMD easier.

Dental anxiety is a common problem: it’s estimated that one in two Americans admits to some level of nervousness about seeing the dentist. On the extreme side of this statistic about 15% of the population even avoid or postpone dental care because of it. While comedy shows routinely make fun of people’s fear of the dentist, the consequences of not receiving needed dental care due to dental anxiety are no laughing matter.
Fortunately, visiting the dentist doesn’t have to be a nerve-wracking, butterflies-in-the-stomach experience. Here are 3 ways to make sure your next visit is more pleasant.
The right dentist. Dental care is more than technical—it’s also personal and relational. The most important element for reducing dental visit anxiety is a provider you’re comfortable with and that you trust. It’s especially important for high anxiety patients to find a dentist who also has compassion for how they feel and won’t judge them—instead, working with them to find just the right combination of techniques and possible medications that encourage relaxation.
Oral sedation. For many people nervous about dental visits the answer could be prescribed sedation medication taken an hour or so before their appointment. Typically a mild sedative, the dose is just enough to help them relax. It’s also often coupled with other methods like nitrous oxide or local anesthesia for a pain-free and unstressed experience.
IV sedation. For people with high levels of anxiety, it’s often beneficial to increase the level of sedation. One of the best ways to do this is with an intravenous flow of medication that will place a person in a deeper state of relaxation. Although this method requires careful vital sign monitoring during the procedure, it’s often the best way to calm patients with high anxiety so they can receive the dental care they need.
Working with your dentist, you can develop just the right mix of these and other methods for making your dental visits easier. No matter what your level of anxiety, you don’t have to avoid the dentist nor needed dental care.

Periodontal (gum) disease can cause a number of devastating effects that could eventually lead to tooth loss. However, you may be more prone to a particular effect depending on the individual characteristics of your gums.
There are two basic types of gum tissues or “periodontal biotypes” that we inherit from our parents: thick or thin. These can often be identified by sight — thinner gum tissues present a more pronounced arch around the teeth and appear more scalloped; thicker tissues present a flatter arch appearance. While there are size variations within each biotype, one or the other tends to predominate within certain populations: those of European or African descent typically possess the thick biotype, while Asians tend to possess the thin biotype.
In relation to gum disease, those with thin gum tissues are more prone to gum recession. The diseased tissues pull up and away (recede) from a tooth, eventually exposing the tooth’s root surface. Receding gums thus cause higher sensitivity to temperature changes or pressure, and can accelerate tooth decay. It’s also unattractive as the normal pink triangles of gum tissue between teeth (papillae) may be lost, leaving only a dark spot between the teeth or making the more yellow-colored root surface visible.
While thicker gum tissues are more resilient to gum recession, they’re more prone to the development of periodontal pockets. In this case, the slight gap between teeth and gums grows longer as the infected tissues pull away from the teeth as the underlying bone tissue is lost. The resulting void becomes deeper and more prone to infection and will ultimately result in further bone loss and decreased survivability for the tooth.
Either of these conditions will require extensive treatment beyond basic plaque control. Severe gum recession, for example, may require grafting techniques to cover exposed teeth and encourage new tissue growth. Periodontal pockets, in turn, must be accessed and cleaned of infection: the deeper the pocket the more invasive the treatment, including surgery.
Regardless of what type of gum tissue you have, it’s important for you to take steps to lower your risk of gum disease. First and foremost, practice effective daily hygiene with brushing and flossing to remove bacterial plaque, the main cause of gum disease. You should also visit us at least twice a year (or more, if you’ve developed gum disease) for those all important cleanings and checkups.
