There is a primary principle dentists follow regarding tooth decay—treat it as soon as you find it. Something as simple and routine as filling a cavity could prevent future tooth loss.
But treating a cavity at or below the gum line could be anything but simple and routine. Older adults who may also be dealing with gum recession are more likely to have these kinds of cavities where the gums block clear access to it.
But there is a way to access gum-covered cavities with a minor surgical procedure known as crown lengthening. Crown lengthening is commonly used in cosmetic dentistry to expose more of the visible teeth when there's an overabundance of gum tissue or if the teeth are disproportionately small. We can use it in this instance to surgically relocate the blocking gum tissue out of the way of the cavity.
After numbing the area with local anesthesia, tiny incisions will be made in the gums to create a tissue flap. After reshaping the underlying bone to recreate normal anatomy but at a different level, this flap is then moved and sutured to a new position. This exposes enough tooth structure so that the cavity can be repaired after gum healing.
As with any minor surgery, there's a very slight risk of bleeding and/or infection with crown lengthening. If you undergo this procedure, you'll receive post-care instructions for the first few days afterward including avoiding strenuous activities, eating only soft foods and using an ice pack the day of surgery to help control swelling.
This versatile procedure can help save a tooth that might otherwise be lost due to decay. And, it might even improve your appearance.

As your dental provider, we're always alert for signs of tooth decay or periodontal (gum) disease, the two leading causes of tooth loss. But we're also watching for less common conditions that could be just as devastating.
Root resorption falls into this latter category: it occurs when a tooth's root structure begins to break down and dissolve (or resorb). It's a normal process in primary ("baby") teeth to allow them to loosen and give way when permanent teeth are ready to erupt.
It's not normal, though, for permanent teeth. Something internally or—more commonly—externally causes the root structure to break down. External resorption usually occurs at the neck-like or cervical area of a tooth around the gum line. Known as external cervical resorption (ECR), it can first appear as small, pinkish spots on the enamel. These spots contain abnormal cells that cause the actual damage to the root.
We don't fully understand how root resorption occurs, but we have identified certain factors that favor its development. For example, it may develop if a person has experienced too much force against the teeth during orthodontic treatment. Injury to the periodontal ligaments, teeth-grinding habits or some dental procedures like internal bleaching may also contribute to later root resorption.
Early diagnosis is a major part of effective treatment for root resorption. Because it's usually painless and easily overlooked, resorption is often too difficult to detect in its early stages without x-rays—a good reason for regular dental exams. Beginning spots or lesions are usually small enough to surgically remove the tissue cells causing the damage and then filled with a tooth-colored filling material. If it has advanced further, we may also need to perform a root canal treatment.
At some point, the damage from root resorption can be too great, in which case it might be best to remove the tooth and replace it with a dental implant or similar restoration. That's why catching root resorption early through regular dental exams can give you the edge for saving your tooth.

Even with modern prevention and treatment advances, losing teeth in later life is still a sad but common part of human experience. Just as generations have before, many today rely on dentures to regain their lost dental function and smile.
But although effective, dentures have their weaknesses. The most serious: they can't prevent jawbone deterioration, a common problem associated with tooth loss.
Bone health depends on chewing forces applied to the teeth to stimulate replacement growth for older bone cells. When teeth are gone, so is this stimulation. Dentures can't replicate the stimulus and may even accelerate bone loss because they can irritate the bone under the gums as they rest upon them for support.
But there's a recent advance in denture technology that may help slow or even stop potential bone loss. The advance incorporates implants with dentures to create two hybrid alternatives that may be more secure and healthier for the supporting bone.
The first is known as an overdenture, a removable appliance similar to a traditional denture. But instead of deriving its support from the gums alone, the overdenture attaches to three to four implants (or only two, if on the lower jaw) that have been permanently set into the jawbone. This not only increases stability, but the implants made of bone-friendly titanium attract and foster increased bone growth around them. This can help slow or even stop the cycle of bone loss with missing teeth.
The second type is a fixed denture. In this version, four to six implants are implanted around the jaw arch. The denture is then secured in place to these implants with screws. It's a little more secure than the overdenture, but it's also more expensive and requires good quality bone at the implant sites.
If you've already experienced significant bone loss you may first need bone grafting to build up the implant sites for these options, or choose traditional dentures instead. But if you're a good candidate for an implant-supported denture, you may find it provides better support and less risk of continuing bone loss than traditional dentures.

While children are less likely than adults to experience periodontal (gum) disease, the same can't be said for tooth decay. One aggressive form of decay called early childhood caries (ECC) can have a profound effect on a child's dental development and future health.
That's why dentists who treat young children often use a variety of preventive measures to reduce the risk of ECC and other dental diseases. One popular method is dental sealants, dental material coatings applied to the biting surfaces of teeth that fill in the naturally occurring pits and crevices. These areas are highly susceptible to plaque formation, a bacterial biofilm of food particles that tends to accumulate on teeth. It's the bacteria that live in plaque that are most responsible for the formation of tooth decay.
Roughly one third of children between the ages of 6 and 11 have received some form of dental sealant. It's a quick and painless procedure applied during a routine office visit. The dentist brushes the sealant in liquid form on the teeth, and then hardens it with a special curing light. It's common for children to begin obtaining sealant protection as their molars begin to come in.
With their increased popularity among dentists, researchers have conducted a number of studies to see whether dental sealants have a measurable effect reducing tooth decay. After reviewing the cases of thousands of children over several years, many of these studies seemed to show that children who didn't receive sealants were more than twice as likely to get cavities as children who did.
As evidence continues to mount for dental sealants' effectiveness protecting young children from decay, both the American Dental Association and the American Academy of Pediatric Dentistry now recommend it for all children. Not only can sealants help preserve children's teeth now, but they can reduce future costs for dental treatment that results from tooth decay.
A beautiful smile is a balanced smile, especially in regard to your gums. A normal smile usually shows 4 mm or less of gum tissue along with about 10 mm of tooth length. But if your gums show more than that, your smile may seem too gummy. In terms of perceived balance, this could detract from your smile's attractiveness.
Fortunately, you don't have to live with a gummy smile—there are various ways to correct or minimize its effect. First, though, we'll need to determine the underlying cause before deciding on the best treatment. And, there are several possible causes, the obvious being too much gum tissue present. Teeth that appear shorter due to wear or incomplete eruption could also make the gums appear larger.
We may be able to correct these size problems by surgically removing and reshaping excess gum tissues and possibly the underlying bone to reveal more of the teeth. We can also bond composite resins or porcelain veneers to shorter teeth to make them appear larger.
But not all gummy smile problems pertain directly to the teeth and gums; instead, it could be your upper lip moves too far up as you smile (hypermobility). Or, your upper jaw may be too long for your face, which can also cause too much of the gums to show during smiling.
With upper lip hypermobility, we may be able to inhibit the lip muscles' movement temporarily with Botox injections that partially paralyze the muscles (the effect eventually wears off, so this treatment will need to be repeated). A periodontist, an oral surgeon, or a plastic surgeon could also permanently alter the upper lip movement through a surgical procedure. Surgery may also be necessary for an abnormally long upper jaw: orthognathic surgery re-positions the jaw to the skull, which can lessen the amount of gums showing.
If your smile is too gummy, we can transform it. But first, let's find out what the real cause is with a comprehensive dental examination. Once we know, we can better advise you on the best way to bring beautiful balance to your smile.
