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.

Although dental care has made incredible advances over the last century, the underlying approach to treating tooth decay has changed little. Today’s dentists treat a decayed tooth in much the same way as their counterparts from the early 20th Century: remove all decayed structure, prepare the tooth and fill the cavity.
Dentists still use that approach not only because of its effectiveness, but also because no other alternative has emerged to match it. But that may change in the not-too-distant future according to recent research.
A research team at Kings College, London has found that a drug called Tideglusib, used for treating Alzheimer’s disease, appears to also stimulate teeth to regrow some of its structure. The drug seemed to cause stem cells to produce dentin, one of the tooth’s main structural layers.
During experimentation, the researchers drilled holes in mouse teeth. They then placed within the holes tiny sponges soaked with Tideglusib. They found that within a matter of weeks the holes had filled with dentin produced by the teeth themselves.
Dentin regeneration isn’t a new phenomenon, but other occurrences of regrowth have only produced it in tiny amounts. The Kings College research, though, gives rise to the hope that stem cell stimulation could produce dentin on a much larger scale. If that proves out, our teeth may be able to create restorations by “filling themselves” that are much more durable and with possibly fewer complications.
As with any medical breakthrough, the practical application for this new discovery may be several years away. But because the medication responsible for dentin regeneration in these experiments with mouse teeth is already available and in use, the process toward an application with dental patients could be relatively short.
If so, a new biological approach to treating tooth decay may one day replace the time-tested filling method we currently use. One day, you won’t need a filling from a dentist—your teeth may do it for you.
Tooth decay is a highly destructive dental disease, responsible along with periodontal (gum) disease for most adult tooth loss. And we become even more susceptible to it as we get older.
One form of decay that’s especially prominent among senior adults is a root cavity. Similar to a cavity in the crown (visible tooth), this form instead occurs at or below the gum line in the roots. They happen mainly because the roots have become exposed due to gum recession, a common consequence of periodontal (gum) disease and/or brushing too hard.
Exposed roots are extremely vulnerable to disease because they don’t have the benefit of protective enamel like the tooth crown, covered instead with a thin and less protective mineral-like material called cementum. Normally, that’s not a problem because the gums that would normally cover them offer the bulk of the protection. But with the gums receded, the roots must depend on the less-effective cementum for protection against disease.
Although we treat root cavities in a similar way to those in the crown by removing decayed structure and then filling them, there’s often an added difficulty in accessing them below the gum line. Because of its location we may need to surgically enter through the gums to reach the cavity. This can increase the effort and expense to treat them.
It’s best then to prevent them if at all possible. This means practicing daily brushing and flossing to remove bacterial plaque, the thin, built-up biofilm on teeth most responsible for both tooth decay and gum disease. You should also visit your dentist at least twice a year for professional cleanings and advanced prevention methods like topical fluoride to strengthen any at-risk teeth.
You should also seek immediate treatment at the first sign of gum disease to help prevent gum recession. Even if it has occurred, treating the overall disease could help renew gum attachment. We may also need to support tissue regeneration with grafting surgery.
Root cavities are a serious matter that could lead to tooth loss. But by practicing prevention and getting prompt treatment for any dental disease, you can stop them from destroying your smile.

Humanity has been waging war against tooth decay for millennia — with this relentless opponent often getting the better of us.
Over the last century, however, significant treatment advances have turned the tide of battle in our favor. Perhaps the greatest of these advancements is our deeper grasp of the disease process — new understandings that have altered our treatment strategy. Rather than wait for cavities to occur and then repair the damage, we now focus on stopping the damage from occurring in the first place.
Prevention starts by reducing factors that contribute to tooth decay. We can signify these detrimental factors with the acronym BAD:
Bad Bacteria. Millions of bacteria inhabit our mouths at any one time, but only a few strains produce the acid that causes decay. We want to reduce their population by removing dental plaque (where they feed and grow) through daily brushing and flossing, and, at a minimum, semi-annual office cleanings.
Absence of Saliva. This important fluid neutralizes acid and strengthens tooth enamel. Some people, however, suffer from reduced saliva flow. We want to find the cause (for example, a side effect of certain prescription drugs) and then improve saliva flow.
Dietary Habits. A diet heavy in sugar and acid (particularly sodas and soft drinks) gives bacteria a ready food source and increases the mouth’s acidic level. Chronic high acid levels in particular are often too great for normal saliva flow to overcome and neutralize. Reducing the amount and frequency of these food items creates a healthier oral environment.
Reducing BAD factors is only half of our prevention focus. We also want to promote SAFE factors that enhance tooth health and strength: Sealants, especially for children, that shield tooth surfaces from decay; Antimicrobial rinses that target and rid the mouth of acid-producing bacteria and give healthy bacteria room to develop; Fluoride, a proven enamel-strengthening chemical available in dental products, many drinking water systems and as a topical application in dental offices; and an Effective diet that’s rich in nutrients and low in sugar and acid as already mentioned.
Keeping the focus on reducing BAD factors and promoting SAFE factors will greatly increase your chances of personally winning the war against tooth decay.

Even though a child’s primary (“baby”) teeth eventually give way, it’s still important to treat them if they become decayed. Primary teeth serve as guides for the emerging permanent teeth — if they’re lost prematurely, the permanent tooth may come in misaligned.
If the decay, however, affects the tooth’s inner pulp, it poses complications. A similarly decayed adult tooth would be treated with a root canal in which all the pulp tissue, including nerve fibers and blood vessels, are removed before filling and sealing. Primary teeth, however, are more dependent on these nerves and blood vessels, and conventional filling materials can impede the tooth’s natural loss process. It’s better to use more conservative treatments with primary teeth depending on the degree of decay and how much of the pulp may be affected.
If the decay is near or just at the pulp, it’s possible to use an indirect pulp treatment to remove as much of the softer decay as possible while leaving harder remnants in place: this will help keep the pulp from exposure. This is then followed with an antibacterial agent and a filling to seal the tooth.
If the pulp is partially exposed but doesn’t appear infected, a technique called direct pulp capping could be used to cover or “cap” the exposed pulp with filling material, which creates a protective barrier against decay. If decay in a portion of the pulp is present, a pulpotomy can be performed to remove the infected pulp portion. It’s important with a pulpotomy to minimize the spread of further infection by appropriately dressing the wound and sealing the tooth during and after the procedure.
A pulpectomy to completely remove pulp tissue may be necessary if in the worst case scenario the pulp is completely infected. While this closely resembles a traditional root canal treatment, we must use sealant material that can be absorbed by the body. Using other sealants could inhibit the natural process when the primary tooth’s roots begin to dissolve (resorb) to allow it to eventually give way.
These all may seem like extraordinary efforts to save a tooth with such a short lifespan. But by giving primary teeth a second chance, their permanent successors will have a better chance of future good health.
