When we refer to periodontal (gum) disease, we’re actually talking about a family of progressive, infectious diseases that attack the gums and other tissues attached to the teeth. Caused primarily by bacterial plaque left on tooth surfaces from inefficient oral hygiene, gum disease can ultimately lead to tooth loss.
There’s only one way to stop the infection and restore health to diseased tissues — remove all of the offending plaque and calculus (hardened plaque deposits) possible from tooth and gum surfaces, including below the gum line at the roots. The basic tools for this task are specialized hand instruments called scalers or ultrasonic equipment that vibrates plaque loose. A series of cleaning sessions using these tools could stop the infection and promote healing if followed with a consistent, efficient daily hygiene habit.
There are times, however, when the infection has progressed so deeply below the gum line or into the tissues that it requires other procedures to remove the plaque and infected tissue. One such situation is the formation of an abscess within the gum tissues, a pus-filled sac that has developed in response to infection. After administering local anesthesia, the abscess must be treated to remove the cause and allow the infectious fluid to drain. The area is then thoroughly flushed with saline or an antibacterial solution.
The gum tissues are not completely attached to the tooth surface for a small distance creating a space. These spaces are called periodontal pockets when they are inflamed and continue to deepen as the disease progresses. These inflamed and sometimes pus-filled pockets form when tissues damaged by the infection detach from the teeth. If the pockets are located near the gum line, it may be possible to clean out the infectious material using scaling techniques. If, however, they’re located four or more millimeters below the gum line a technique known as root planing may be needed, where plaque and calculus are shaved or “planed” from the root surface. As the disease progresses and the pockets deepen, it may also be necessary for surgical intervention to gain access to the tooth roots.
To stop gum disease and promote soft tissue healing, we should use any or all treatment tools at our disposal to reach even the most difficult places for removing plaque and calculus. The end result — a saved tooth — is well worth the effort.

Dental cleanings are an important part of regular dental office visits. Performed by a dental hygienist or dentist, cleanings serve two purposes: to remove bacterial plaque and calculus (hardened deposits of plaque) from tooth surfaces missed during daily brushing and flossing; and to remove stains that can dull your smile.
There are different degrees of cleaning, including root planing that removes plaque and calculus deep below the gum line, usually for patients affected by periodontal (gum) disease. For patients in good oral health, the basic cleaning approach is known as prophylaxis, a term derived from the Greek for guarding or preventing beforehand. The techniques used in a prophylaxis remove both “coronal” (tooth surfaces visible above the gum line) plaque and staining, providing both therapeutic and cosmetic benefits.
A typical prophylaxis includes a procedure known as scaling. Hygienists use special instruments known as scalers to remove plaque and calculus by hand, or an ultrasonic device that vibrates plaque loose and is flushed away with water. The procedure removes that rough coating you often feel as you rub your tongue against your teeth, leaving the tooth surfaces feeling smooth.
Tooth polishing is a subsequent procedure to scaling that also removes plaque and surface stains. Polishing is carried out with a motorized instrument with a rubber cup in which a polishing (or “prophy”) paste is contained. The hygienist moves the rapidly rotating cup filled with the paste over the tooth surface to remove plaque and stains. The end result is a highly smooth surface and a much shinier appearance.
People with dental insurance plans are often concerned tooth polishing may be viewed strictly as a cosmetic procedure, and thus not fully qualify for benefits. This should not be the case if coded properly: tooth polishing is part of the overall prophylaxis to remove plaque and staining. The primary purpose is therapeutic and preventive; the cosmetic effect is a by-product. Most dental plans will cover one or two prophylaxes (scaling and tooth polishing) a year, but there are variations so individuals should check their plans.

Considering the costs, many people view replacing a back tooth as less important than a more visible front tooth. They’re rarely seen, so who will notice?
You might, eventually. A missing back tooth can set off a chain reaction of problems that can affect your overall dental health. Besides playing an important role in chewing food, back teeth also redistribute most of the chewing force away from the front teeth. Their absence can also affect the bite: adjacent teeth to the missing one will tend to migrate toward the open space, causing them to tip and rotate into an improper position. This can cause an increase in tooth mobility, excessive wear and erosion, and endanger their survival in the long run.
To avoid these and other problems you should consider some form of replacement. Most dentists prefer a dental implant for its life-like appearance and durability, and because its titanium post has a natural affinity with bone. Bone cells will grow around and permanently adhere to the implant, which may stop and even reverse bone loss in some cases.
Implants, though, require a certain amount of bone structure initially to anchor and position properly. If you have inadequate bone and don’t want to bone graft the area, the next best option is a fixed bridge, in which the missing tooth is replaced with an artificial crown known as a pontic. The pontic is fused between two support crowns that are permanently affixed to the natural teeth on either side of the missing tooth (also known as abutments). While fixed bridges restore function and inhibit tooth migration, they require the natural tooth supporting the bridge to be reduced to accommodate the crowns placed on them. This permanently alters them and places them at higher risk for future nerve damage, gum disease and decay.
One final option is a removable partial denture (RPD). Although RPDs restore function and improve appearance, their movement within the mouth may place additional stress on the teeth that hold them in place. This movement over time could damage or loosen them.
We can discuss which option is best for you after a complete dental exam. The important thing, though, is to replace the back tooth as soon as possible — doing nothing could cost you much more in the long run.
