Nothing grabs your attention like a sharp tooth pain, seemingly hitting you out of nowhere while you’re eating or drinking. But there is a reason for your sudden agony and the sooner you find it out, the better the outcome for your oral health.
To understand tooth sensitivity, we need to first look at the three layers of tooth anatomy. In the center is the pulp filled with blood vessels and nerve bundles: it’s completely covered by the next layer dentin, a soft tissue filled with microscopic tubules that transmit sensations like pressure or temperature to the pulp nerves.
The third layer is enamel, which completely covers the crown, the visible part of a tooth. Enamel protects the two innermost tooth layers from disease and also helps muffle sensations so the tooth’s nerves aren’t overwhelmed. The enamel stops at about the gum line; below it the gums provide similar protection and sensation shielding to the dentin of the tooth roots.
Problems occur, though, when the dentin below the gums becomes exposed, most commonly because of periodontal (gum) disease. This bacterial infection caused by dental plaque triggers inflammation, which over time can weaken gum tissues and cause them to detach and shrink back (or recede) from the teeth. This can leave the root area vulnerable to disease and the full brunt of environmental sensations that then travel to the nerves in the pulp.
Tooth decay can also create conditions that cause sensitivity. Decay begins when certain oral bacteria multiply and produce higher than normal levels of acid. The acid in turn dissolves the enamel’s mineral content to create holes (cavities) that expose the dentin. Not treated, the infection can eventually invade the pulp, putting the tooth in danger of being lost unless a root canal treatment is performed to remove the infection and seal the tooth from further infection.
So, if you begin experiencing a jolt of pain while eating or drinking hot or cold foods or beverages, see your dentist as soon as possible to diagnose and treat the underlying cause. And protect your teeth from dental disease by practicing daily brushing and flossing, as well as seeing your dentist for regular dental cleanings and checkups. Don’t ignore those sharp pains—your teeth may be trying to tell you something.

Every good oral hygiene regimen has two parts — the part you do (brushing and flossing) and the part we do (professional cleanings and checkups).
But what’s involved with “professional cleanings” — and why do we perform it? The “why” is pretty straightforward — we’re removing plaque and calculus. Plaque is a thin film of bacteria and food remnant that adheres to tooth surfaces and is the main culprit in dental disease. Calculus (tartar) is calcified plaque that occurs over time as the minerals in saliva are deposited in bacterial plaque. It isn’t possible for you to remove calculus regardless of your efforts or hygiene efficiency. Ample research has shown that calculus forms even in germ-free animals during research studies, so regular cleanings are a must to keep you healthy.
The “what” depends on your mouth’s state of health and your particular needs. The following are some techniques we may use to clean your teeth and help you achieve and maintain healthy teeth and gums.
Scaling. This is a general term for techniques to manually remove plaque and calculus from tooth surfaces. Scaling typically encompasses two approaches: instruments specially designed to remove plaque and calculus by hand; or ultrasonic equipment that uses vibration to loosen and remove plaque and calculus, followed by flushing with water and/or medicaments. Scaling can be used for coronal maintenance (the visible surfaces above the gum line) or periodontal (below the gum line).
Root planing. Similar to scaling, this is a more in-depth technique for patients with periodontal disease to remove plaque and calculus far below the gum line. It literally means to “plane” away built up layers of plaque and calculus from the root surfaces. This technique may employ hand instruments, or an ultrasonic application and flushing followed by hand instruments to remove any remaining plaque and calculus.
Polishing. This is an additional procedure performed on the teeth of patients who exhibit good oral health, and what you most associate with that “squeaky clean” feeling afterward. It’s often performed after scaling to help smooth the surface of the teeth, using a rubber polishing cup that holds a polishing paste and is applied with a motorized device. Polishing, though, isn’t merely a cosmetic technique, but also a preventative measure to remove plaque and staining from teeth — a part of an overall approach known as “prophylaxis,” originating from the Greek “to guard or prevent beforehand.”

The March 27th game started off pretty well for NBA star Kevin Love. His team, the Cleveland Cavaliers, were coming off a 5-game winning streak as they faced the Miami Heat that night. Less than two minutes into the contest, Love charged in for a shot on Heat center Jordan Mickey—but instead of a basket, he got an elbow in the face that sent him to the floor (and out of the game) with an injury to his mouth.
In pictures from the aftermath, Love’s front tooth seemed clearly out of position. According to the Cavs’ official statement, “Love suffered a front tooth subluxation.” But what exactly does that mean, and how serious is his injury?
The dental term “subluxation” refers to one specific type of luxation injury—a situation where a tooth has become loosened or displaced from its proper location. A subluxation is an injury to tooth-supporting structures such as the periodontal ligament: a stretchy network of fibrous tissue that keeps the tooth in its socket. The affected tooth becomes abnormally loose, but as long as the nerves inside the tooth and the underlying bone have not been damaged, it generally has a favorable prognosis.
Treatment of a subluxation injury may involve correcting the tooth’s position immediately and/or stabilizing the tooth—often by temporarily splinting (joining) it to adjacent teeth—and maintaining a soft diet for a few weeks. This gives the injured tissues a chance to heal and helps the ligament regain proper attachment to the tooth. The condition of tooth’s pulp (soft inner tissue) must also be closely monitored; if it becomes infected, root canal treatment may be needed to preserve the tooth.
So while Kevin Love’s dental dilemma might have looked scary in the pictures, with proper care he has a good chance of keeping the tooth. Significantly, Love acknowledged on Twitter that the damage “…could have been so much worse if I wasn’t protected with [a] mouthguard.”
Love’s injury reminds us that whether they’re played at a big arena, a high school gym or an outdoor court, sports like basketball (as well as baseball, football and many others) have a high potential for facial injuries. That’s why all players should wear a mouthguard whenever they’re in the game. Custom-made mouthguards, available for a reasonable cost at the dental office, are the most comfortable to wear, and offer protection that’s superior to the kind available at big-box retailers.
