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 a destructive oral disease, which along with periodontal (gum) disease is most responsible for tooth loss. And as you age, your disease risk goes up.
One form of decay older people often experience is root cavities. Unlike those occurring in the visible crown, root cavities often occur below the gum line and are especially destructive to tooth structure.
That's because, unlike the crown protected by ultra-hard enamel, the roots are covered by a thin, mineralized material called cementum. Although cementum offers some protection, it can't compare with the decay-resistant capacity of enamel.
The roots also depend on gum coverage for protection. But unfortunately, the gums can shrink back or recede, usually due to gum disease or over-aggressive brushing, and expose some of the root surface. With only the cementum to protect them, the roots can become highly susceptible to decay. If a cavity forms here, it can rapidly advance into the tooth's interior, the pulp, weakening the tooth and increasing its risk of loss.
To stop the decay, we must treat root cavities much like we do with crown cavities: by removing any decayed structure and then filling the cavity. But root cavities are often more difficult to access depending on how far below the gum line they extend. We may need to perform minor gum surgery to expose the cavity to treat it.
But as with any form of tooth decay, the best strategy is to prevent root cavities in the first place. Your first line of defense is a daily hygiene habit of brushing and flossing to remove dental plaque, the main cause for tooth decay. You should also visit your dentist at least twice a year (or more, if recommended) for more thorough cleanings and checkups. Your dentist can also recommend or prescribe preventive rinses, or apply fluoride to at-risk tooth surfaces to strengthen them.
You should also be on the lookout for any signs of gum disease. If you see swollen, reddened or bleeding gums, see your dentist as soon as possible. Stopping possible gum recession will further reduce your risk of root cavities.

If you suffer frequent sinus infections, you might want to talk with your dentist about it. It could be your chronic sinus problems stem from a deeply decayed or infected tooth.
Sinuses are hollow, air-filled spaces in the front of the skull associated with nasal passages. The largest, the maxillary sinuses, are located just behind the cheekbones and above and to the rear of the upper jaw on either side of the face. These sinuses can become painfully congested when infected.
One possible cause for an infection in the maxillary sinus can occur in certain people whose upper back teeth (the molars and premolars) have roots that are close to or even protrude into the sinus. This is normally a minor anatomical feature, unless such a tooth becomes infected.
An infection in teeth with advancing decay or whose nerve tissue has died will eventually reach the root tip through tiny passageways called root canals. If the roots are close to or penetrating the maxillary sinus, the infection could move into the sinus. This is known as Maxillary Sinusitis of Endodontic Origin (MSEO).
A case of MSEO could potentially go on for years with occasional flare-ups of sinus congestion or post-nasal drip. Because of the nature of the infection within the sinus, the affected tooth itself may not show the normal signs of infection like sensitivity or pain. Doctors may attempt to treat the sinus infection with antibiotics, but because the actual source of the infection is within the tooth, this therapy is often ineffective.
If your doctor or dentist suspects MSEO, they may refer you to an endodontist, a specialist in root canals and interior tooth problems. With their advanced diagnostic capabilities, endodontists may have a better chance of accurately diagnosing and locating the source of a tooth-related infection.
As with any non-vital tooth, the likely treatment will be root canal therapy in which the infected tissue within the tooth is removed and the empty spaces filled to prevent future infection. For MSEO, the treatment not only preserves the tooth but may also relieve the infection within the sinus.
Other than the common cold, tooth decay is the most prevalent disease in the world. And while a cavity or two may seem like a minor matter, tooth decay’s full destructive potential is anything but trivial. Without proper prevention and treatment, tooth decay can cause pain, tooth loss and, in rare cases, even death.
This common disease begins with bacteria in the mouth. Though these microscopic organisms’ presence is completely normal and at times beneficial, certain strains cause problems: they consume left over carbohydrates in the mouth like sugar and produce acid as a byproduct. The higher the levels of bacteria the higher the amount of acid, which disrupts the mouth’s normal neutral pH.
This is a problem because acid is the primary enemy of enamel, the teeth’s hard protective outer shell. Acid causes enamel to lose its mineral content (de-mineralization), eventually producing cavities. Saliva neutralizes acid that arises normally after we eat, but if the levels are too high for too long this process can be overwhelmed. The longer the enamel is exposed to acid, the more it softens and dissolves.
While tooth decay is a global epidemic, dental advances of the last century have made it highly preventable. The foundation for prevention is fluoride in toothpaste and effective oral hygiene — daily brushing and flossing to removing plaque, a thin film of food remnant on teeth that’s a feeding ground for bacteria, along with regular dental visits for more thorough cleaning and examination. This regular regimen should begin in infancy when teeth first appear in the mouth. For children especially, further prevention measures in the form of sealants or topical fluoride applications performed in the dentist office can provide added protection for those at higher risk.
You can also help your preventive measures by limiting sugar or other carbohydrates in your family’s diet, and eating more fresh vegetables, fruit and dairy products, especially as snacks. Doing so reduces food sources for bacteria, which will lower their multiplication and subsequently the amount of acid produced.
In this day and age, tooth decay isn’t a given. Keeping it at bay, though, requires a personal commitment to effective hygiene, lifestyle choices and regular dental care. Doing these things will help ensure you and your family’s teeth remain free from this all too common disease.

For over a century dentists treated tooth decay by removing both diseased portions of the tooth and healthy structure deemed at risk for future decay. In the 1970s, though, a new approach emerged, known as Minimally Invasive Dentistry (MID). This practice protocol attempts to preserve as much of the healthy structure as possible.
Before MID, dentists followed a decay treatment protocol developed in the 19th Century. A part of this became known as extension for prevention calling for dentists to remove healthy structure considered vulnerable to decay. Besides reducing the tooth's volume, this practice also resulted in, by today's standards, larger than necessary fillings.
It was thought that removing this additional material would make it easier to clean bacterial plaque, the source of decay, but later, research showed the practice couldn't guarantee the teeth wouldn't be reinfected.
Since then we've learned a lot more about teeth and have developed new ways to detect decay at earlier stages. X-ray imaging, for example, has transitioned largely from film to digital technology, providing more detailed images at greater magnification. This, along with laser fluorescence and infrared cameras, has made it easier to detect the first tiny stages of decay.
We can also limit tooth decay damage by boosting enamel strength with fluoride applications and sealants or reducing decay-causing bacteria with anti-bacterial rinses. We've also seen advancement in techniques like air abrasion that remove decayed tooth material while leaving more healthy structure intact better than using a traditional dental drill.
Restoring teeth after treatment has also improved. While dental metal amalgam is still used for some fillings, the main choice is now composite resin. These new tooth-colored dental materials require less tooth preparation (and thus less material loss) and bond well to the remaining structure, resulting in a stronger tooth.
Following a MID protocol leads to less intervention and less time in the dentist's chair. It also means preserving more of a natural tooth, an important aim in promoting long-lasting dental health.
