A "toothy grin" might be endearing, but not necessarily healthy. More of the teeth showing may mean your gums have pulled back or receded from the teeth. If so, it's not just your smile that suffers—the parts of teeth protected by the gums could become more susceptible to disease.
There are a number of causes for gum recession. Some people are more likely to experience it because of genetically thinner gum tissues. Over-aggressive brushing could also contribute to recession. But the most common cause by far is periodontal (gum) disease, a bacterial infection triggered by dental plaque accumulating on teeth mainly as a result of inadequate hygiene.
There are some things we can do to help heal and restore recessed gums, most importantly treating gum disease. The number one goal of treatment is to uncover and remove all dental plaque from tooth and gum surfaces, which can take several sessions and sometimes minor surgery if the infection has reached the tooth roots. But removing plaque and tartar (calcified plaque) is necessary to stop the infection and allow the gums to heal.
For mild recession, this may be enough for the gums to regain normal coverage. But in more severe cases we may need to help rejuvenate new tissue with grafting surgery. In these highly meticulous procedures a surgeon uses microscopic techniques to position and attach donated tissue to the recession site. The graft serves as a scaffold on which new tissue growth can occur.
While these treatments can be effective for reversing gum recession, they often require time, skill and expense. It's much better to try to prevent gum recession—and gum disease—in the first place. Prevention begins with daily brushing and flossing to prevent plaque buildup, as well as regular dental visits for more thorough cleanings. Be on the lookout too for any signs of a beginning gum infection like swollen, reddened or bleeding gums and see your dentist as soon as possible to minimize any damage to your gums.
Caring for your gums is equally as important as caring for your teeth. Healthy gums equal a healthy mouth—and an attractive smile.

In real life he was a hard-charging basketball player through high school and college. In TV and the movies, he has gone head-to-head with serial killers, assorted bad guys… even mysterious paranormal forces. So would you believe that David Duchovny, who played Agent Fox Mulder in The X-Files and starred in countless other large and small-screen productions, lost his front teeth… in an elevator accident?
“I was running for the elevator at my high school when the door shut on my arm,” he explained. “The next thing I knew, I was waking up in the hospital. I had fainted, fallen on my face, and knocked out my two front teeth.” Looking at Duchovny now, you’d never know his front teeth weren’t natural. But that’s not “movie magic” — it’s the art and science of modern dentistry.
How do dentists go about replacing lost teeth with natural-looking prosthetics? Today, there are two widely used tooth replacement procedures: dental implants and bridgework. When a natural tooth can’t be saved — due to advanced decay, periodontal disease, or an accident like Duchovny’s — these methods offer good looking, fully functional replacements. So what’s the difference between the two? Essentially, it’s a matter of how the replacement teeth are supported.
With state-of-the-art dental implants, support for the replacement tooth (or teeth) comes from small titanium inserts, which are implanted directly into the bone of the jaw. In time these become fused with the bone itself, providing a solid anchorage. What’s more, they actually help prevent the bone loss that naturally occurs after tooth loss. The crowns — lifelike replacements for the visible part of the tooth — are securely attached to the implants via special connectors called abutments.
In traditional bridgework, the existing natural teeth on either side of a gap are used to support the replacement crowns that “bridge” the gap. Here’s how it works: A one-piece unit is custom-fabricated, consisting of prosthetic crowns to replace missing teeth, plus caps to cover the adjacent (abutment) teeth on each side. Those abutment teeth must be shaped so the caps can fit over them; this is done by carefully removing some of the outer tooth material. Then the whole bridge unit is securely cemented in place.
While both systems have been used successfully for decades, bridgework is now being gradually supplanted by implants. That’s because dental implants don’t have any negative impact on nearby healthy teeth, while bridgework requires that abutment teeth be shaped for crowns, and puts additional stresses on them. Dental implants also generally last far longer than bridges — the rest of your life, if given proper care. However, they are initially more expensive (though they may prove more economical in the long run), and not everyone is a candidate for the minor surgery they require.

There’s one sure thing about tooth decay: you can’t ignore it. In fact, the best outcomes result from finding it early and treating it before it enters the pulp in the center of the tooth, often a filling or similar treatment.
If it does advance to the pulp, you may need a root canal treatment to save the tooth. This is a moderately invasive procedure where we access the pulp and root canals, tiny passageways leading to the root and supporting bone. We then remove all the diseased tissue and fill the empty pulp chamber and root canals with a special filling. Later we’ll crown the tooth for added protection against future infection or fracture of the tooth.
But there’s also another less-invasive method than a root canal called pulp capping. It’s only appropriate to use, however, if the pulp has become exposed or almost exposed by decay, but hasn’t yet shown signs of disease.
Pulp capping can be either direct or indirect. We use direct pulp capping if the healthy pulp has been exposed by the disease process. We first isolate the tooth from the rest of the mouth to prevent contamination and then proceed to remove all of the tooth’s decayed dentin structure. We then apply a biocompatible material directly over the pulp to protect it from further decay and to facilitate healing. We then restore the tooth, usually with a filling, to its proper function and life-like appearance.
When the pulp is threatened by decay but not yet exposed, we may then use the indirect method. In this approach we first remove most of the decayed dentin, but leave a small amount next to the pulp to keep it covered. We then treat this remaining dentin with a material to help it heal and re-mineralize, followed by a temporary filling of the tooth. A few months later we’ll remove this filling and inspect the treated dentin. If it has regenerated sufficiently, we remove any remaining decay and permanently restore the tooth.
As we said, pulp capping is only used with patients with deep decay whose pulp tissue is healthy. But when we can use it we can avoid some of the permanent alterations that often come with a root canal treatment and still save the tooth.

In the battle against tooth decay, fluoride is an important weapon. Since the discovery of its dental health benefits a century ago, fluoride has been credited with saving countless teeth.
But over its history in dental care, this natural-occurring chemical has also had its share of controversy with concerns raised from time to time on potential health dangers. These run the gamut from “conspiracy theory” speculations to credible research like a 2006 National Research Council study that suggested a possible increased risk of bone fracture or cancer from over-consumption of fluoride.
Even so, there is actually little evidence or even record of incidence for such dire consequences. The only definitive health effect from fluoride found after decades of copious research is a condition called fluorosis, a permanent staining effect on the teeth. Fluorosis poses a cosmetic problem but does not harm the health of the teeth.
Moderation in fluoride use seems to be the key to gaining its health benefits while avoiding fluorosis. One influential fluoride researcher, Dr. Steven Levy, estimates 0.05-0.07 milligrams of fluoride per one kilogram of body weight (about a tenth the weight of a grain of salt for every two pounds) is sufficient to gain the optimum dental benefit from fluoride.
The real question then is whether your family’s current consumption of fluoride is within this range. That will depend on a number of factors, including whether your local water utility adds fluoride to your drinking water supply and how much. You may also be ingesting fluoride through processed foods, juices and even some bottled waters. And you can encounter fluoride in dental care including toothpastes and clinical treatments.
One way to moderate your family’s fluoride intake is to be sure all your family members are using the correct amount of fluoride toothpaste for their age while brushing. Infants need only a slight smear on the end of the brush, while older children can brush adequately with just a pea-sized amount. For other tips and advice, talk to your dentist about your family’s fluoride intake and how you might adjust it.
Even with the possibility of fluorosis, fluoride still provides an incredible benefit in preventing tooth decay. By understanding fluoride and keeping your intake within normal ranges you can maximize its benefit for healthier teeth and minimize the fluorosis risk.

While tooth decay is a potential problem at any age, the risk increases as you grow older. Not only are senior adults more susceptible, decay is often more difficult to treat. That’s because cavities can occur at or below the gum line, often due to gum recession.
If that’s the case, we won’t be able to fill the cavity in the usual way because the gum tissue is in the way. To make it possible to treat, we may need to perform a minor surgical procedure known as crown lengthening.
As the name implies, the procedure helps expose more of the crown, the tooth’s visible part, from the surrounding gum tissue. In basic terms, we’re repositioning the gum tissue away from the biting surface of a tooth to make room for a filling. It’s also useful for improving a tooth’s appearance by making it look longer, or creating room for a crown or other dental restoration.
After applying a local anesthesia, the dentist (or periodontist, a specialist in the gums) creates a tiny flap of gum tissue with a series of incisions. This allows the dentist to move the affected gums out of the way to access the underlying bone. The dentist then reshapes the bone to adequately support the gum tissue when it’s finally repositioned to expose the crown. In its new and improved position, the dentist sutures the gum tissue in place.
For a few days afterward, the patient will need to restrict their diet to soft foods, avoid strenuous activities and apply an ice pack to help reduce swelling the day of surgery. They will also prescribe a pain reliever and possibly an antibiotic to reduce the chances of infection.
While most people return to normal activities a few days later, you’ll usually have to wait a few weeks for the gums to heal before undergoing any further treatments for the affected teeth. But even with the wait, crown lengthening could make it possible to not only save your tooth but improve your smile as well.
