Gum recession — when the gum tissue covering teeth wears away — is a serious matter. If the roots become exposed you'll not only have increased sensitivity and possible discomfort, your teeth can become more susceptible to decay.
There are a number of reasons for gum recession, including overaggressive brushing and flossing, poor fitting appliances like dentures or braces, or genetics (inheriting a thin gum tissue type or poor tooth position). Perhaps the most common reason, though, is periodontal (gum) disease. Caused by bacterial plaque, a thin film of food particles that builds up on tooth surfaces, the disease weakens the gum tissues around teeth, causing them ultimately to detach and “roll up” toward the roots.
Treating the gum infection by removing the built-up plaque and calculus (hardened plaque deposits) will help stop recession or even reverse it. Â As we remove plaque the infection subsides and the gums cease to be inflamed. If they haven't receded too far they may re-grow and renew their attachment to the teeth.
In other cases, though, the recession may have progressed too far and too rapidly toward root exposure. Gums in this condition may require tissue grafts to the recessed area to create or regenerate new tissue.
Most grafting techniques fall into one of two categories. The first is known as free gingival grafting where a thin layer of skin is removed or "freed" from the roof of the patient's mouth (the palate), shaped and then stitched to the recession site.
The second category is called connective tissue grafting, most often used to cover exposed roots. In this case the donor material is transplanted from the donor site to the recipient site, but the recipient site's tissue covers the donor connective tissue graft as it still maintains a physical attachment to the original location. The recipient site can thus maintain a blood supply, which can result in quicker, more comfortable healing than with free gingival grafting.
Connective tissue grafting does, however, require sophisticated microsurgical techniques, along with the surgeon's in-depth skill and art, to prepare both the donor and recipient sites. Allografts (donor skin from another person) may also be used as a donor tissue and placed beneath the recipient site tissue thereby avoiding a second surgical site.
Gum tissue grafting can be an intense undertaking, but the results can be astounding. Not only will restoring recessed gum tissues give your teeth a new lease on life, it will revitalize your smile.

It's difficult to measure how x-ray imaging has transformed dentistry since its use became prominent a half century ago. As equipment and methods standardized, the technology revolutionized the way we diagnose tooth decay and other mouth-related issues.
One of the more useful of these methods is called the bitewing x-ray. The term comes from the shape of the device a patient holds between their teeth with the film attached on the side toward their tongue. We direct the x-ray beam to the outside of the patient's cheek, where it passes through the teeth to expose on the film. Its particular design provides clearer images since the patient's bite helps keep the film still and distortion-free, making it easier to view signs of early tooth decay.
Bitewing x-rays usually consist of four films, two on either side of the mouth, necessary to capture all of the teeth (children with smaller jaws, however, often only require one film per side). How frequently they're conducted depends on a number of factors, including the patient's age: children or young adolescents are usually filmed more frequently than adults, usually every six to twelve months. Frequency also depends on a patient's particular decay risk — the higher the risk the more frequent the x-ray.
Regardless of how often they're performed, a similar application principle applies with bitewing x-rays as with any other radiological method: As Low As Reasonably Achievable (ALARA). With the ALARA principle in other words, we're looking for that sweet spot where we're able to detect the earliest stages of dental disease with the least amount of radiation exposure.
Bitewings fit this principle well: a patient receives only a fraction of the radiation exposure from a four-film bitewing as they do from a daily dose of environmental radiation. Factor in new digital technology that reduces exposure rates and bitewings pose virtually no health risk to patients, especially if conducted in a prudent manner.
The benefits are well worth it. Thanks to bitewing x-rays we may be able to diagnose decay early and stop it before it causes you or your family member extensive tooth damage.
Wearing braces isn't just for teenagers — straightening teeth can be just as viable a need when you're an adult. For example, it may be necessary to first move teeth away from an empty tooth socket before you obtain a dental implant or other restoration.
But braces could have complications, especially if you have periodontal (gum) disease. These infections caused by plaque, a thin film of bacteria and food particles, inflame and weaken gum tissues and erode supporting bone. It can be treated and brought under control — but keeping it under control requires daily brushing and flossing, along with frequent office cleanings and checkups.
Braces can make this more difficult: it's harder to brush and floss effectively through the hardware of brackets and wires, which can give plaque a chance to build up. Patients susceptible to gum disease are more likely to have re-infections while wearing braces. The hardware can also cause enamel to come in prolonged contact with acid, which can dissolve its mineral content and open the door to tooth decay.
Clear aligners are an alternative to braces that can accomplish tooth movement while minimizing infection flare-ups for people with gum disease. Aligners are a series of customized clear plastic trays worn over the teeth, with each succeeding tray incrementally moving the teeth further than the preceding one. After wearing one tray for a specified time period, you then switch to the next tray. The teeth gradually move to the desired new position over the course of the aligner series.
This option is especially advantageous for gum disease patients because the trays can be removed temporarily for brushing and flossing. There are also other benefits: we can hide a missing tooth space with a temporary false tooth attached to the aligner; and, they're nearly invisible so it won't be obvious to others you're undergoing orthodontic treatment.
Not all orthodontic situations benefit from this alternative, while some cases may call for a combination approach between aligners and braces. But in the right setting, clear aligners are a good choice for not only obtaining better teeth position, but also helping you avoid a new encounter with dental disease.
While tooth loss can occur at any age, replacing one in a younger patient requires a different approach than for someone older. It’s actually better to hold off on a permanent restoration like a dental implant if the person is still in their teens.
This is because a teenager’s jaws won’t finish developing until after nineteen or in their early twenties. An implant set in the jawbone before then could end up out of alignment, making it appear out of place — and it also may not function properly. A temporary replacement improves form and function for now and leaves the door open for a permanent solution later.
The two most common choices for teens are a removable partial denture (RPD) or a bonded fixed bridge. RPDs consist of a plastic gum-colored base with an attached prosthetic (false) tooth matching the missing tooth’s type, shape and jaw position. Most dentists recommend an acrylic base for teens for its durability (although they should still be careful biting into something hard).
The fixed bridge option is not similar to one used commonly with adult teeth, as the adult version requires permanent alteration of the teeth on either side of the missing tooth to support the bridge. The version for teens, known as a “bonded” or “Maryland bridge,” uses tiny tabs of dental material bonded to the back of the false tooth with the extended portion then bonded to the back of the adjacent supporting teeth.
While bonded bridges don’t permanently alter healthy teeth, they also can’t withstand the same level of biting forces as a traditional bridge used for adults. The big drawback is if the bonding breaks free a new bonded bridge will likely be necessary with additional cost for the replacement.
The bridge option generally costs more than an RPD, but buys the most time and is most comfortable before installing a permanent restoration. Depending on your teen’s age and your financial ability, you may find it the most ideal — though not every teen is a good candidate. That will depend on how their bite, teeth-grinding habits or the health of surrounding gums might impact the bridge’s stability and durability.
A complete dental exam, then, is the first step toward determining which options are feasible. From there we can discuss the best choice that matches your teen’s long-term health, as well as your finances.
Tooth decay and periodontal (gum) disease pose the most common dangers to dental health. But there are some rare conditions that can also place teeth at risk to be on the lookout for during regular dental checkups.
One such condition is root resorption in an adult tooth, in which the root itself or its surface breaks down and is absorbed by the body. Resorption occurs naturally in a primary (“baby”) tooth so it can loosen and give way for an incoming permanent tooth. Â Resorption still occurs in a limited form with young permanent teeth but should eventually stop.
Sometimes, though, it doesn’t, either from the inside of the tooth out (internal resorption) or more often from the outside in, usually around the neck-like (or “cervical”) portion of the tooth. This more common occurrence, External Cervical Resorption (ECR), can first appear as pink spots on the enamel and then progress into cavity-like areas. If not found and treated promptly, damage can occur quickly and lead to tooth loss.
We don’t fully understand the exact nature and causes for ECR, but we have identified risk factors for its development. Excessive orthodontic force on the teeth or any other trauma can cause damage to the periodontal ligament (which holds teeth in place with the jaw bone). Teeth grinding habits and some dental procedures like internal tooth whitening can also be risk factors.That being said, though, the vast majority of people who experience these issues don’t develop ECR.
Although the causes aren’t fully understood, we can still treat it: the key to success is early detection. You probably won’t notice early signs of ECR, but we can often detect spots from routine x-rays. We can then remove the tissue cells within the lesions causing the damage and restore the area with a tooth-colored filling material. If ECR has extended near the tooth’s interior pulp layer, then a root canal treatment may be needed.
Needless to say, the more extensive ECR occurs in the roots, the less likely the tooth can be saved and may need to be extracted. It’s important, therefore, to maintain regular dental checkups (at least twice a year) to increase your chances of catching a developing problem early.
