The various structures in your mouth — your teeth and gums, of course, as well as periodontal tissues that hold teeth in place within the jaw — all function together to create your smile. This includes muscles like the frenum, a fold of muscle tissue that connects the gums to the upper lip, which helps pull the lip upward when you smile.
Unfortunately, an overly large frenum could contribute to an unattractive space between your two upper front teeth. The problem occurs when the frenum grows beyond its normal range and runs between the front teeth to connect with the gums behind them at the forefront of the roof of your mouth. The resulting space that may develop can be closed with orthodontics, but unless the excess frenum tissue is addressed the space may eventually reopen.
The frenum is just one cause among many for a noticeably wide space, including bite problems (malocclusions), finger-sucking habits or missing teeth. We would, therefore, need to examine your mouth to determine the exact cause before beginning any treatment. If indeed the frenum is the source of the problem, it will be necessary to ultimately remove the excess portion through a procedure known as a frenectomy.
A frenectomy is a minor surgical procedure performed by a periodontist, oral surgeon or a general dentist with surgical training. After numbing the area with local anesthesia, the tissue behind the teeth is dissected or reduced in size with a small scalpel or a surgical laser. The wound is then closed with a few stitches; any post-surgical discomfort is usually minimal and managed with non-steroidal anti-inflammatory pain medication. The wound will completely heal within a few weeks.
Most frenectomies are performed after orthodontics to close the space. Removing it prior to tooth movement may result in scar tissue that prevents the space from closing. It’s also easier for the surgeon to gauge how much tissue to remove after space closure to avoid removing too much, which can leave a “black” triangular hole where gum tissue should normally be.
Treating an abnormally large frenum isn’t difficult, but it needs to be coordinated with orthodontic treatment for the best outcome. The end result is a smile that’s both healthy and attractive.

While it may not be one of your favorite features in the dental office, the dental drill is nevertheless necessary for treating problem teeth. It’s used primarily for removing decayed or damaged structure and preparing a tooth for fillings or other restorations.
Dental drills have been used for decades and are quite effective — but they have their drawbacks. Their rotating burrs often remove portions of healthy tooth structure along with decayed material. Friction from the drill action can cause discomfort, so local anesthesia is usually needed. Drills can also emit a high-pitched machine noise that’s unsettling to many patients.
There’s a growing alternative to the drill, known as air abrasion. Although the technology has been around since the 1950s, the development of new suction pumps that capture the resulting dust from its use has made it more palatable as an option to the traditional drill.
Also known as particle abrasion, the technique uses a pressurized stream of fine particles (usually aluminum oxide, an abrasive powder) directed at teeth to wear away (abrade) the tooth’s structural surface. We can be quite precise in the amount of surface material removed, so it’s useful for diminishing stains or roughing the surface for bonding materials like composite resin. We’re also able to remove decayed material with very little impact on surrounding healthy structure, and you may not need anesthesia during the procedure.
While this quiet alternative to the noisier drill is quite versatile, it does have its limitations. It’s not that efficient for preparing larger cavities for restoration or for removing older amalgam fillings. The teeth to be treated must be carefully isolated to prevent the fine particle dust produced from being swallowed by the patient or spread into the air. High-volume suction equipment is a must or the procedure will create a “sandstorm” of particles in the room.
Still, for situations suited to it and with proper isolation measures, air abrasion can be effective and comfortable. If the technology continues to improve, the dental drill may soon become a relic of the past.

While it doesn’t garner the star power of blood, saliva is still an important bodily fluid. A true multi-tasker, saliva contributes in many ways to the function and health of the body, from stronger teeth to more efficient digestion.
Here are six ways saliva helps your mouth and body function properly and stay healthy.
The mouth’s natural cleanser. Bacteria are responsible for much of the dental disease that plagues us, particularly tooth decay and gum disease. Saliva clears the mouth of food remnants, bacteria’s primary feeding source, after we eat. This leaves a cleaner mouth and fewer bacteria to cause infection.
The immune system’s partner. Saliva contains an antibody called Immunoglobulin A (IgA) that attacks disease-causing microorganisms. Along with secreting other antibacterial agents like lactoferrin and lyzozyme that curb the growth and development of bacteria, saliva serves as the body’s first line of defense against pathogens entering through the mouth.
Acid neutralizer. The optimal oral environment is a neutral pH of 7. Many of our foods and beverages, though, are highly acidic, which can raise the mouth’s acid level. The acidic environment causes the minerals in tooth enamel to soften and dissolve (a process called de-mineralization). Saliva restores the balance by neutralizing any remaining acid after we eat (a process that takes about 30 to 60 minutes).
Mineral replacer. Even under normal conditions, enamel will de-mineralize to some extent whenever the mouth becomes acidic. Saliva restores some of the enamel’s lost minerals like calcium and phosphate while it’s neutralizing acid. If fluoride is also present in saliva from fluoridated drinking water or toothpaste, it too is absorbed by the enamel making it stronger and more resistant to acid attacks.
Digestion enhancer. Saliva lubricates the mouth while we eat, making it easier for us to chew (and taste) our food. Saliva also releases the enzyme amylase as we chew to break down starches before the food enters our stomach. The end result is more efficient and comfortable digestion.
The wave of the future in diagnostics. Like blood and urine, saliva contains genetic and disease markers that could tell a physician if a patient has a certain condition. Since collecting a saliva sample is much easier than with these other bodily fluids, diagnosing disease with saliva will become more prevalent as more calibrated devices reach the market.
