Geographic tongue is characterized by harmless lesions, or patches, that can suddenly materialize on the tongue's top surface. The condition gets its name from the physical appearance of the lesions, which resemble smooth, red islands, possibly rimmed with white. Their smoothness comes from the absence

You probably know that many physical and emotional changes you will experience during pregnancy result from an increase in the levels of certain hormones — the chemicals that regulate many important processes in the body. But what you may not realize is that these hormonal variations can affect your

Root canal treatment is a safe and effective way to stop many kinds of tooth pain, and to keep a tooth from being lost due to decay or injury. But if a root canal is recommended for your young child, you may wonder why: Isn't that baby tooth going to fall out in a few years anyway? That's true —

Millions of people regularly take anticoagulant or antiplatelet medications (sometimes called “blood thinners”) to help prevent heart attack and stroke, and to manage a variety of medical conditions including cardiac arrhythmia and stent placement. While these drugs have proven, life-saving benefits,

Fluoride, a naturally occurring mineral, is essential for proper tooth development and the prevention of tooth decay. In communities throughout the United States, tooth decay may still be a significant problem — but it is far less prevalent than it would have been, if not for the fluoridation of public

Your baby's teeth will not be visible at birth. But believe it or not, they already exist beneath the gums. Children's primary teeth begin forming at about the sixth week of pregnancy, and start mineralizing — building the bonelike inner tooth layer (called dentin) and the super-hard enamel layer that

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

Fluoride is a mineral that is naturally present to some degree in both fresh and salt water sources. Its major dental benefit is that it is readily incorporated into the teeth's mineral structure, thereby making them stronger and more decay-resistant. Fluoride can even reverse tiny cavities that are

If you have been told you need root canal treatment, you may be feeling a bit nervous. Not to worry — treating root canal problems is a routine part of dentistry that can relieve certain kinds of tooth pain and help your teeth last longer. As you learn more about this beneficial procedure, you will

In the future, could small cavities be detected early and filled without anesthesia, and with only the minimum removal of tooth material? Will routine dental procedures be performed with patients noticing no vibration or pressure? Will the piercing whine of a dental drill be a sound that's heard in dental

Before prescribing any medications — even lifesaving ones, such as those used to reduce blood pressure or prevent epileptic seizures — your health care professionals carefully weigh the benefits a drug offers against the possible risks of taking it, including its potential side effects. In most cases,

Teeth grinding and clenching are common habits, but that doesn't mean they are harmless. Stresses from the powerful forces generated by grinding and clenching (also known as “bruxing”) can wear down teeth or even loosen them. Teeth that have enamel worn away or scraped off from this repeated rubbing

Today most adults recognize that leading a healthy, active lifestyle is a big plus. Moderate exercise has been shown to help lower blood pressure, keep cholesterol levels under control, and even reduce feelings of anxiety or depression. To stay active, some 150 million adults in the United States get

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

Sometimes, braces alone aren't enough to move teeth into a better position, or to correct trouble with the bite or remedy problems in the growth of the jaws. In those situations, special appliances may be recommended. Orthodontic headgear is the general name for an appliance, worn partly outside the

It's almost impossible to imagine the practice of dentistry without x-ray technology. Radiographs (x-ray pictures) allow dentists to diagnose and treat problems not yet visible to the naked eye, including early tooth decay, gum disease, abscesses and abnormal growths. There is no question that since

In many cases, problems with the bite or the alignment of the teeth can be corrected using today's advanced methods of dental and orthodontic treatment. Sometimes, however, skeletal and dental irregularities aren't so easy to remedy, even with the most up-to-date non-surgical techniques. That's when

If you are missing one or more of your adult teeth, you're not alone — an estimated 178 million Americans have the same condition. Many try to get along without all of their teeth, and suffer from some of the familiar problems that go with the territory: smiles that don't look as appealing as they

When you are a child, your first loose tooth can be cause for celebration; when you are an adult, it definitely is not. Biting and chewing with a tooth that is not securely attached in its socket can be difficult or even painful — and any tooth that becomes loose is at risk of needing to be removed

In the early 20th Century, not long after X-rays were discovered, medical professionals recognized their value as diagnostic tools: They could clearly reveal structures hidden inside the body without the need for risky surgery. At the dawn of the 21st century, a revolutionary new technology has entered

For years, whenever you needed a dental crown (cap), your dentist had to make molds of your teeth which required taking an impression of your teeth. A tray filled with a goopy, putty-like material was used so that a three-dimensional model of the prepared tooth could be created. Using this mold, a dental

If you have lost an entire arch of teeth (top and/or bottom), or are soon to have your remaining teeth removed because they are too unhealthy to save, you may be able to replace them with fixed dentures supported by dental implants. Doctors and patients alike prefer fixed over removable dentures because

Antibiotics are widely prescribed to control bacterial infections. Sometimes they are given before a medical or dental procedure, to prevent a possible infection from occurring; this practice is called "antibiotic prophylaxis." In the recent past, physicians and dentists advised that people with certain

For many teens, braces are a rite of passage: They're one more example of the changes adolescents go through at this time — along with growth in stature, edgier tastes in clothes and music, and an increasing degree of self-awareness. But is there any particular reason why orthodontic appliances and

When you experience pain in your mouth, it's sometimes abundantly clear which tooth is causing it. At other times, the sensation of discomfort is more diffuse, generalized or hard to pinpoint. On occasion, it can even be challenging to determine exactly what problem or combination of problems is causing

If you've ever had needle phobia, you might like to learn about a new technology referred to as an “anesthesia wand,” which is a computer-controlled dental-injection tool. In fact, some people feel it is more of a “magic” wand because it doesn't look like a typical injection and it works even
