Oral Diagnosis and Biopsies
When you come into the dental office for an examination, you might assume that the focus is on your teeth. That's often correct — but don't forget that there are a number of other parts of the oral and facial anatomy that are examined as well. These include areas around and inside the mouth (such as the lips, gums, hard and soft palate, and the tongue) as well as outside the mouth (the skin, muscles and glands in the neck, and the temporomandibular joint). In fact, when it comes to detecting certain oral or systemic (whole-body) diseases, a thorough dental...
TMJ Disorders
If you experience ongoing pain in the area near your ear, your jaw or the muscles on the side of your face, possibly accompanied by a clicking or popping sound or restricted jaw movement, you may be suffering from TMD — an abbreviation for Temporomandibular disorders. Sometimes people incorrectly use the term TMJ to refer to these problems, when in fact TMJ is the abbreviation for the temporomandibular joint — or jaw joint — itself. So while you definitely have a TMJ (two of them in fact), you may or may not have TMD.
TMD, then, describes a group of...
Frequently Asked Questions about Orthodontics
What do orthodontists do?
Orthodontists are dental specialists who diagnose and treat problems with the position, alignment or spacing of the teeth, and related irregularities in the face and the jaw. A number of special treatments, including braces and other oral appliances, are used to correct these problems.
Why should I (or my loved ones) get orthodontic treatment?
There are two good reasons: aesthetics and function. Having an attractive smile not only changes the way people see you — it enhances your own self-image as well. Orthodontic treatment also allows your teeth to function better and makes it easier to...
Removable Dentures
Full or partial tooth loss, if left untreated, doesn't just affect a person's self-image — it can also increase the risk of developing nutritional problems and other systemic health disorders. Fortunately, there's a reliable and time-tested method for treating this condition: full or partial dentures.
Dentures are just one option for replacing missing teeth; some of the others include fixed bridgework and dental implants. Each method has its particular pluses and minuses, which should be carefully considered. There are also several varieties of dentures available to address specific issues, from partial dentures to implant-supported overdentures. The best option for you...
Cracked Teeth
Firmly anchored in your jaw and protected by an outer coating of tough enamel, your teeth are remarkably strong — yet it's still possible for them to chip, crack, or even break. In fact, there is some evidence that today, our teeth are developing cracks at a record rate. This may be due to the fact that people are living longer (giving teeth more time to accumulate damage), or that our stress levels are increasing (which may cause teeth clenching and grinding).
Biting on hard objects, receiving a blow to the mouth, or having large cavities (or old amalgam fillings)...
Crowns and Bridgework
Dentistry is an art as well as a science; dental crowns offer a perfect example of this. A dental crown or “cap” is a covering that fits over a damaged, decayed or unattractive tooth. It can even replace a tooth entirely as part of dental bridgework.
A crown completely covers a tooth above the gum line. This is in contrast to a dental veneer, which only covers a tooth's front surface and needs natural tooth structure to support it. Therefore, if a tooth is missing a significant amount of structure above the gum line, a crown would be the restoration...
David Copperfield
This Magician knows that maintaining a great smile takes more than a simple abracadabra!
Dear Doctor sat down with master illusionist David Copperfield to discuss more than a bit of magic. From what inspires him to his greatest feats, he enlightened us on how he became the most spellbinding enchanter of our time and expressed the importance of a healthy smile.
While talking to us at his Secret Warehouse of Magic in Las Vegas, David shared with us how his love for magic began. He admitted that his father who always aspired to be an actor gave up his own...
Dental Technology
The complex devices all around us — from long-range satellite links in our cars and offices to powerful computers in our hand-held gadgets — prove beyond a doubt that we live in a technology-driven world. In the field of dentistry, new technology is constantly changing the way diseases are diagnosed, routine procedures are performed, and illnesses are prevented. Although they may seem unfamiliar at first, new and improved dental technologies offer plenty of real benefits for patients. Here's a look at some of the latest examples, coming soon to (or now appearing at) a dental office near you.

Holistic Dentistry
Over recent years, as health awareness in general has increased, many people have become more concerned with what they put in their bodies and how that affects their health. Some desire a more egalitarian partnership with their doctors and dentists, so that they can make the most informed healthcare decisions based on the latest information. For those who are seeking an approach to dental healthcare that takes the whole person into account, holistic dentistry offers many benefits.
What Is Holistic Dentistry?
It's not about what exams you've taken, what degrees you hold, or what groups you join. Holistic dentistry is...
Functional Orthodontic Appliances
Most of the time, orthodontic treatment involves moving the teeth into better positions with braces or clear aligners. While these are the most familiar appliances used in orthodontic treatment, we may also recommend devices called “functional appliances” to help correct more serious bite problems. Functional appliances are designed to harness natural forces (such as those produced by muscular activity and jaw growth) to bring the bite into better alignment. Examples of functional appliances include the Activator, Bionator, Twin Block and Herbst® appliances.
Some of these devices are fixed in the mouth (like braces), and can't be taken out at home;...
Palatal Expanders
A major benefit of receiving orthodontic treatment in childhood is that it's possible to take full advantage of a youngster's own natural growth process to treat or even prevent malocclusions (“bad bites”). A palatal expander is a device designed to help do that.
Palatal expanders create more space in a child's mouth by gradually widening the upper jaw. Although this may sound scary, it's really quite easy — both to do and to tolerate. That's because the upper jaw (maxilla) actually develops as two separate halves that don't completely fuse together until sometime after puberty. Before that happens, the two...
Professional Teeth Cleanings
Even if you brush and floss your teeth faithfully, it is important that you have your teeth professionally cleaned on a regular basis. (Of course, if you aren't quite so meticulous about your oral hygiene, it's even more important!) After a thorough cleaning, your teeth will feel smooth and squeaky-clean, and they will probably look a lot brighter too. But professional teeth cleanings aren't done for looks alone.
Why do your teeth need this kind of attention? Essentially, it's because over time they tend to build up a layer of plaque (a sticky, bacteria-rich film) and hard deposits (called tartar,...
Diabetes And Oral Health
Diabetes is a group of chronic inflammatory diseases that affect the body's ability to process sugar. If you have diabetes, it is particularly important to maintain excellent oral health. That's because diabetics are more prone to oral infections such as periodontal (gum) disease, which can result in tooth loss if left untreated. Conversely, the presence of gum disease can make it harder for people with diabetes to control their blood sugar levels.
Periodontal disease is a chronic ailment that is also associated with an elevated level of systemic (whole-body) inflammation. Like diabetes, it may have wide-ranging consequences outside the mouth...
Dry Mouth
Everybody gets a dry mouth from time to time. Temporary mouth dryness can be brought on by dehydration, stress, or simply the normal reduction in saliva flow at night. But persistent mouth dryness, a condition known as xerostomia, is cause for concern.
Xerostomia occurs when your salivary glands, which normally keep your mouth moist by secreting saliva, are not working properly. A chronic lack of saliva has significant health implications. For one thing, it can be difficult to eat with a dry mouth; tasting, chewing and swallowing may also be affected. This could compromise your nutrition. Also, a dry mouth...
Eating Disorders and Oral Health
Millions of people in the United States, particularly teenage girls and young women, suffer from health-threatening eating disorders, and dentists are often the first to spot the signs. Why? The repeated, self-induced vomiting that characterizes bulimia nervosa has a pronounced effect on teeth. Anorexia nervosa (self-starvation) can also have some noticeable effects on oral health.
More than 90% of those with bulimia experience tooth erosion. This is caused by acid from the stomach, which can dissolve the enamel when it comes in contact with teeth during vomiting. Teeth that have lost enamel can appear worn, chip easily, and become sensitive...
