One of the most important revolutions in healthcare in recent decades is the increasing use of lasers. Now, laser technology is making a showing in dental care for the treatment of periodontal (gum) disease.
Lasers (an acronym for "Light Amplification by Stimulated Emission of Radiation") narrowly focus and amplify light within a small area. First developed in the early 1960s, laser technology rapidly advanced in the ensuing decades with more compact and precise devices that were eventually safe and effective for many types of medical procedures. Its remarkable features are now available for the primary focus of gum disease treatment—removing bacterial plaque.
Plaque is a thin, built-up film of bacteria and food particles on tooth and gum surfaces that serves as a haven for the bacteria that cause gum disease. The continuing presence of plaque and calculus (tartar) enables the infection to thrive and advance within the gum tissues, ultimately damaging them along with supporting bone. As the tissues weaken and bone volume diminishes, the teeth are at greater risk for loss.
It's necessary, therefore, first and foremost to remove all detectable plaque and calculus to stop the infection. This is traditionally done with special hand tools called scalers used to manually remove plaque, or with ultrasonic equipment that vibrates plaque loose to be flushed away with water. These procedures can take numerous sessions and may result in some minor post-procedural discomfort and bleeding during the cleaning.
But lasers specifically designed for plaque removal can minimize tissue damage and resulting discomfort. Because the particular laser light used reacts only with plaque and diseased tissue, it can remove them without disturbing nearby healthy tissue usually more efficiently than traditional scaling. Dentists who've used the technology frequently report less bleeding and higher patient satisfaction.
But before lasers for gum disease treatment are widely adopted, the procedure must undergo further scrutiny. Reports from dentists notwithstanding, not enough research studies have been performed to date that meet the necessary scientific criteria. But if the evidence so far from the field holds up, it's quite possible lasers will one day become a regular part of dental practice for treating gum disease.

If you press your tongue against your teeth, unless something is badly wrong they won't budge. In fact, your teeth are subjected to a fair amount of pressure each day as you chew and eat, and yet they remain firmly in place.
But there's a deeper reality—your teeth do move! No, it's not a paradox—the gum and bone tissues that hold your teeth in place allow for slight, imperceptible changes in the teeth's position. Their natural ability to move is also the basis for orthodontics. Here are 3 more facts you may not know about your teeth's natural ability to move.
Teeth are always on the move. Teeth are held firmly within the jawbone by an elastic gum tissue called the periodontal ligament and a thin layer of bony-like material called cementum. In response to pressure changes, though, the bone dissolves on the side of the teeth in the direction of pressure and then rebuilds behind it, solidifying the teeth's new position, a process that happens quite slowly and incrementally. And it will happen for most of us—some studies indicate more than 70% of people will see significant changes in their bite as they age.
Orthodontics works with the process. Orthodontic appliances like braces or clear aligners apply targeted pressure in the direction the orthodontist intends the teeth to move—the natural movement process does the rest. In the case of braces, a thin metal wire is laced through brackets bonded to the front of the teeth and then anchored, typically to the back teeth. The orthodontist incrementally tightens the wire against its anchors over time, encouraging tooth movement in response to the pressure. Clear aligners are a series of removable trays worn in succession that gradually accomplish the same outcome.
Watch out for the rebound. That nice, straight smile you've gained through orthodontics might not stay that way. That's because the same mechanism for tooth movement could cause the teeth to move back to their former positions, especially right after treatment. To avoid this outcome, patients need to wear a retainer, an appliance that holds or "retains" the teeth in their new positions. Depending on their individual situations and age, patients may have to wear a retainer for a few months, years or from then on.

March is national nutrition month—a good time to look at the connection between diet and oral health. You probably know that sugar is a major culprit in dental problems. This is because bacteria feed on sugars and create acid that can lead to tooth decay and gum disease. Avoiding sugary foods and drinks as much as possible is a good rule of thumb, but there are some food choices that actually benefit your oral health. Here are nutrition tips that will help keep your smile healthy for life:
Say cheese. Dairy products such as milk, cheese and yogurt contain calcium and phosphorus to build teeth and strengthen the supporting bone. And cheese neutralizes acid in the mouth to help fight cavities and gum disease.
Choose lean proteins. Lean meats, poultry, fish, milk and eggs help strengthen teeth. They are rich in protein and phosphorous, which is essential for building strong bones and teeth.
Eat a rainbow. Fruits and vegetables provide many key nutrients, including vitamins necessary for healing, bone strength, and healthy gums. Besides being nutritious, fruits and veggies scrub your teeth while you chew and stimulate the production of saliva, which is necessary for neutralizing acid and rebuilding enamel.
Nibble on nuts. Nuts contain protein, fiber and healthy fats. They also contain essential vitamins and minerals to keep teeth strong and gums healthy. Further, chewing nuts stimulates saliva production, lowering the risk of tooth decay.
Go for the grains. Studies have shown that eating too many refined carbohydrates such as white bread and sweet bakery items can lead to chronic inflammation, which is a factor in gum disease, heart disease, stroke and other conditions. In contrast, eating complex carbohydrates such as whole grains may reduce inflammation in the body.
What you put in your body can play a big role in preventing tooth decay and gum disease, so choose foods that provide the right building blocks for optimal dental and overall health.
