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.

While the term “plastic surgery” might bring to mind face lifts or tummy tucks, not all procedures in this particular surgical field are strictly cosmetic. Some can make a big difference in a person’s health.
One example is periodontal plastic surgery, which corrects gum tissue loss around the teeth. Although these procedures can indeed improve appearance, they more importantly help save teeth.
Gum loss is most often a consequence of periodontal (gum) disease, a bacterial infection arising from a thin film of food particles on the teeth called dental plaque. As the disease weakens the gums’ attachment to teeth, they shrink back or recede, exposing the area around the roots. Without the protective cover the gums provide the roots, they become more susceptible to decay.
In milder cases of gum recession, treating the infection often results in the gums regaining their normal attachment to teeth. But with more advanced recession, natural gum healing may not be enough to reverse it. For such situations grafting donor tissue to the recessed area can help stimulate new tissue growth.
While gum tissue grafts can come from an animal or other human, the most likely source is from the person themselves. In one type of procedure, free gingival grafting, the surgeon locates and completely removes (or “frees”) a thin layer of skin resembling gum tissue, typically from the roof of the mouth, shapes it and then transplants it by suturing it to the recession site. Both donor and recipient sites heal at about the same rate in two to three weeks.
Another technique is known as connective tissue grafting. In this procedure the surgeon partially removes the donor tissue from its site while leaving a portion containing blood vessels intact. The palatal tissue is still used and transported to fit beneath the tissue that’s still attached to the blood supply. This connective tissue graft is then positioned and sutured to the recipient site while still maintaining its blood supply connection at the donor site. Maintaining this connection facilitates healing and increases the chances the graft will “take” and become firmly attached to the new site.
Grafting procedures require advanced techniques and skills. But with them we may be able to restore gum attachment to teeth with an impact on appearance and dental health that’s well worth the effort.
