We all know that dentistry can do amazing things these days to give you the smile you've always dreamed of. With the latest cosmetic and restorative dental techniques, it is possible to achieve amazingly natural-looking results. But how do we map out the best route to a better smile? And how do we know that the results will hold up over time?
Every individual has a unique set of conditions in his or her mouth and it is our job to figure out how you have come to your present state, dentally speaking. We need to correct or at least manage any factors that could risk the success of your treatment. These risk factors fall into four basic categories:
Periodontal Risk — This involves the condition of the structures that support your teeth, including your gum and bone tissue. It's important to establish good periodontal health before we perform any restorative or cosmetic procedures.
Biomechanical Risk — This has to do with the structural integrity of your teeth. We will look at whether any tooth structure has been lost due to decay, and take steps to reduce your susceptibility to decay if necessary.
Functional Risk — This relates to your bite: how your teeth, muscles and jaw joints are functioning. For example, do you have excessive tooth wear or joint pain? If so, you are at a higher risk in this category and we need to figure out why.
Aesthetic Risk — This is the most subjective of the categories as beauty is in the eye of the beholder. Still, if you display a lot of your teeth and gums when you smile, any issues you have (gum recession, for example) will be that much more visible and affect your smile more. We will have to take this into account when we plan your treatment.
Only when we have determined how best to minimize your risk in all four of these categories can we restore or enhance your smile in a way that will not only look great but also last as long as possible.
“Smile, and the world smiles with you,” the old saying goes. For people who are afraid to smile because they don't like how their smile looks, the twenty-first century offers a myriad of solutions. Smiling shows your teeth in their various shapes, colors, and sizes, your gums and gum line, your tooth alignment, spacing, and bite all in relation to the rest of your face. Any of these can now be improved.
Through the knowledge, skills, and combined experience of our dental team, it is now possible to make teeth whiter, brighter, and more evenly aligned, to alter tooth shape and size, and to make the teeth and gum line more proportionally balanced. Here are some options for cosmetic dentistry:
- Polish. Remove unwanted stains on outside tooth surfaces by having your teeth polished.
- Teeth Whitening. If teeth are stained or have just lost their luster, whitening is a safe and effective way to lighten a smile.
- Porcelain veneers. Applying a thin layer of dental porcelain restorative material to replace stained or damaged tooth enamel can truly change a smile.
- Porcelain crowns. If teeth are damaged by decay or trauma, porcelain crowns can replace the parts of the teeth that show above the gum line.
- Orthodontics. For teeth that are not in their correct and functional position, a variety of orthodontic techniques can be used including traditional braces, clear aligners and moreÃ¢Â€Â”to improve crooked teeth or a malaligned bite.
- Dental implants. Nothing ruins a smile more than missing teeth. Entire teeth can be replaced, including the roots and the crowns, using dental implants. These are exact replicas of the natural teeth and can be made to match their neighbors exactly.
Considering the costs, many people view replacing a back tooth as less important than a more visible front tooth. They’re rarely seen, so who will notice?
You might, eventually. A missing back tooth can set off a chain reaction of problems that can affect your overall dental health. Besides playing an important role in chewing food, back teeth also redistribute most of the chewing force away from the front teeth. Their absence can also affect the bite: adjacent teeth to the missing one will tend to migrate toward the open space, causing them to tip and rotate into an improper position. This can cause an increase in tooth mobility, excessive wear and erosion, and endanger their survival in the long run.
To avoid these and other problems you should consider some form of replacement. Most dentists prefer a dental implant for its life-like appearance and durability, and because its titanium post has a natural affinity with bone. Bone cells will grow around and permanently adhere to the implant, which may stop and even reverse bone loss in some cases.
Implants, though, require a certain amount of bone structure initially to anchor and position properly. If you have inadequate bone and don’t want to bone graft the area, the next best option is a fixed bridge, in which the missing tooth is replaced with an artificial crown known as a pontic. The pontic is fused between two support crowns that are permanently affixed to the natural teeth on either side of the missing tooth (also known as abutments). While fixed bridges restore function and inhibit tooth migration, they require the natural tooth supporting the bridge to be reduced to accommodate the crowns placed on them. This permanently alters them and places them at higher risk for future nerve damage, gum disease and decay.
One final option is a removable partial denture (RPD). Although RPDs restore function and improve appearance, their movement within the mouth may place additional stress on the teeth that hold them in place. This movement over time could damage or loosen them.
We can discuss which option is best for you after a complete dental exam. The important thing, though, is to replace the back tooth as soon as possible — doing nothing could cost you much more in the long run.

Implants are highly regarded by both dentists and patients for their versatility and durability. But it’s their life-like appearance that “seals the deal” as the restoration of choice — not only mimicking an individual tooth, but emerging from the gum line and blending indistinguishably with other teeth in color and symmetry.
To achieve this result, we must consider a few factors beforehand, particularly the amount of bone available at the intended implant site. An implant requires a certain amount of bone to properly position it for the most natural crown appearance. The bone present around adjacent teeth can also affect your appearance: in the absence of adequate bone the papillae, triangular shaped gum tissue between teeth, may not regenerate properly between the implant and the natural teeth. This can leave a noticeable void, what dentists call “black hole disease.”
Bone loss is a significant problem particularly after tooth loss. It’s quite possible for you to lose a quarter of the bone’s width in the first year after tooth loss. To avoid this, we often use bone grafting techniques immediately after extraction to lessen bone loss; if it’s already occurred we may be able to use similar reconstructive techniques to rebuild and encourage renewed bone growth. In the end, though, if there remains a significant level of bone loss it may be necessary to consider another option for tooth replacement other than implants.
The thickness of your gum tissue, a genetic trait, can also have an impact on the implant’s ultimate appearance. Thicker gum tissues are generally more resilient and easier to work with surgically. Thinner gum tissues are more susceptible to recession and tend to be more translucent, which could cause the underlying metal implant to be visible. Thus, working with thinner gum tissues requires a more delicate approach when trying to achieve a visually appealing result.
All these factors must be balanced, from implantation to final crown placement. But with careful planning and attention to detail throughout the process, many of these issues can be overcome to produce a satisfying result — a new and appealing smile.

The final emergence of permanent teeth in late adolescence marks the end of a long process beginning in the womb with the formation of our primary or “baby” teeth. Permanent teeth form in a similar way as buds high in the jaw, continuing to grow until the primary teeth ahead of them fall away. The crowns of the new adult teeth eventually break through the gum tissue and emerge (erupt) into view.
At least, that’s normally what should happen; sometimes, though, a tooth may only erupt partially or not at all, a condition known as impaction. The crown remains partially or fully submerged below the gum line, causing the tooth to press against other teeth, potentially damaging them. It can also make periodontal (gum) tissues adjacent to the area more susceptible to disease. Wisdom teeth are especially prone to this kind of impaction, to the extent they’re often surgically removed (extracted) to avoid future problems to adjacent teeth or the bite.
Upper canines (the “eye teeth” normally located directly below the eyes) are also subject to impaction. But because of their highly visible position, extracting them could have an adverse impact on the patient’s smile. In this case, we often attempt instead to expose and ultimately save the tooth.
Before taking any action, however, an orthodontic examination is conducted first to pinpoint the exact position of the impacted tooth and determine how that position might affect moving teeth into a more desired alignment. If we find the impacted canine is in a workable position, the next step is to surgically uncover the tooth from the gum tissue (a minor procedure usually performed by an oral surgeon or periodontist). Once exposed, an orthodontic bracket with a small attached gold chain is bonded to the tooth. The gums are then sutured back into place with the chain exposed and allowed to heal.
At some future point an orthodontist will attach the chain to orthodontic hardware that will pull the impacted tooth into proper position over several months. As a result, the upper canine becomes “un-impacted”; the dangers to surrounding teeth and tissues are also reduced. And, just as important, we can preserve the tooth and with orthodontics achieve an attractive, normal smile.
