If you've ever had a run-in with cavities, you know the drill (no pun intended): After getting a local anesthetic for pain, the dentist removes any decayed dental tissue, as well as some healthy tissue, and then fills the cavity to restore the tooth. It's an effective treatment protocol we've been using for well over a century.
It does, however, have its drawbacks. For one, although necessary, removing healthy dental tissue can weaken the overall tooth structure. The dental drill used during the procedure is also unpleasant to many people: Although it doesn't cause any pain thanks to the anesthetic, the sounds and pressure sensations associated with it can be unsettling.
But advances in dental tools, technology and techniques are addressing these drawbacks in traditional tooth decay treatment. In other words, treating a tooth with cavities today is taking on a lighter touch. Here are 3 reasons why.
Earlier detection. The key to effective treatment is to find tooth decay in its earliest stages. By doing so, we can minimize the damage and reduce the extent of treatment needed. To do this, we're beginning to use advanced diagnostic tools including digital x-rays, intraoral cameras and laser fluorescence to spot decay, often before it's visible to the naked eye.
Re-mineralizing enamel. One of the advantages of early detection is to catch tooth enamel just as it's undergoing loss of its mineral content (demineralization) due to contact with acid. At this stage, a tooth is on the verge of developing a cavity. But we can use minimally invasive measures like topically applied fluoride and CPP-ACP (a milk-based product) that stimulates enamel re-mineralization to prevent cavity formation.
Less invasive treatment. If we do encounter cavities, we no longer need to turn automatically to the dental drill. Air abrasion, the use of fine substance particles under high pressure, can precisely remove decayed material with less loss of healthy tissue than a dental drill. We're also using newer filling materials like composite resins that don't require enlarging cavities as much to accommodate them.
These and other techniques—including laser technology—are providing superior treatment of tooth decay with less invasiveness. They can also make for a more pleasant experience when next you're in the dentist's chair.

Tooth decay is one of two dental diseases most responsible for tooth loss (gum disease being the other). In the absence of treatment, what starts as a hole or cavity in a tooth's outer layers can steadily advance toward its interior.
Most people associate cavities with the crown, the part of a tooth you can see. But cavities can also occur in a tooth's roots, especially with older adults. Root cavities pose two distinct difficulties: They can lead to more rapid decay spread than crown cavities within a tooth; and they're harder to detect.
Tooth roots are ordinarily covered by the gums, which protects them from bacterial plaque, the main cause for decay. But roots can become exposed due to receding gums, a common problem with seniors who are more susceptible to gum disease.
Unlike the enamel-covered crowns, tooth roots depend on gum coverage for protection against bacteria and the acid they produce. Without this coverage, the only thing standing between tooth decay and the roots is a thin material called cementum.
If decay does enter a tooth's interior, saving it often requires a root canal treatment to remove decayed tissue in the inner pulp and root canals, and then replacing it with a filling. But if we're able to discover a root cavity in its early stages, we may be able to fill it like a crown cavity.
The best strategy, though, is to prevent root cavities from forming. This starts with a dedicated daily regimen of brushing and flossing to remove dental plaque. If you're at high risk for root cavities, we may also recommend antibacterial mouthrinses and other aids.
Regular dental visits are also a must: a minimum of twice-a-year dental cleanings to remove stubborn plaque and calculus (hardened plaque) deposits. For added protection against root cavities, we can also apply fluoride varnish to strengthen teeth. And regular visits are the best way to detect any cavity in its early stages when treatment is less invasive.
A heightened risk of dental problems like root cavities are a part of the aging process. But partnering together, we can lower that risk and increase the longevity of your teeth.

Advanced tooth decay is a serious dental problem that can threaten an affected tooth's survival. But for decades now dentists have reliably used root canal treatment to better a decayed tooth's odds. This routine procedure performed with dental drill and special hand tools removes infected tissue inside a tooth and replaces the voids with a filling to prevent future infection.
But now there's a new way to perform a root canal—with a surgical laser. Lasers, amplified and focused light beams, aren't new to healthcare—they're an integral feature of many routine medical treatments and surgeries. But their use is relatively new to dentistry, and to endodontics (treating the interior of teeth) in particular.
Lasers can be used in root canal treatment to perform a number of tasks. They can remove diseased tissue and other debris from the innermost tooth pulp. They can be used to clean and shape root canal walls in preparation for filling. And they can also be used to soften and mold the filling material to fit more precisely within a tooth's particular root canal network.
Although laser-assisted root canal therapy isn't yet widespread, laser's limited use to date has given us a fair picture of both their advantages and disadvantages. As with other medical laser applications, lasers are very precise in removing diseased tissue without too much disruption of healthy tissue. There's less need for anesthesia than with dental drills, and lasers are a lot less noisy and jarring. Patients by and large experience less bleeding, as well as less discomfort or infection afterward.
But because laser light can only travel in a straight line, they're difficult to use in many tightly curved root canals. In these cases, the traditional methods are better suited, although a laser can be used in conjunction with other tasks. Temperature with lasers must also be carefully managed lest the high heat that's often generated damages natural tissues.
Although lasers won't be replacing traditional treatment methods for decayed teeth in the foreseeable future, there's hope they'll become more commonplace as technology and techniques continue to advance. Lasers can only improve what already is an effective means of saving teeth.

Archeologists can tell us quite a bit about our primitive ancestors. For example, because of their coarse, abrasive diet and a primitive understanding of oral hygiene, their teeth had a rough go of it. They simply wore out faster — a contributing factor, no doubt, to their short life spans of thirty or forty years.
But thanks to improvements in lifestyle, healthcare and diet, people live much longer today. And so do their teeth, thanks to advances in dental care and disease prevention. While teeth still wear to some degree as we age, if we care for them properly with daily oral hygiene and regular dental visits, we can keep that wear to a minimum. Teeth truly can last a lifetime.
Unfortunately, it's still all too common for people to lose their teeth prematurely. The main reason: the two most prevalent dental diseases, tooth decay and periodontal (gum) disease. Tooth decay arises from high concentrations of mouth acid that erode enamel, teeth's irreplaceable protective shell. Gum disease is an infection that damages the bone supporting tissues as it infiltrates deep below the visible gum line.
While they occur by different mechanisms, the two diseases have some commonalities. They both, of course, can lead to tooth loss. And, they're both triggered by oral bacteria found in dental plaque, a thin film of food particles built up on tooth and gum surfaces. Multiplying bacteria feed on plaque and produce acid as a by-product. And certain bacterial strains infect gum tissues.
Both of these diseases can be treated successfully, especially if detected early. But the better approach is to prevent them in the first place. This introduces another commonality — they share the same prevention strategy of daily, comprehensive brushing and flossing for plaque removal, regular dental cleanings and checkups, and a sharp eye for any signs of disease like bleeding gums or tooth pain.
With diligent dental care and close attention to your oral health, you increase your chances of avoiding the full threat of these diseases.Â And with healthy teeth, you have a better chance of living a long and healthy life.

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.
