A traditional root canal procedure can be a “life-saver” for a decayed or injured tooth. But while it’s usually the best course for a damaged adult tooth, variations of the procedure are advisable for a new permanent tooth in a child or young adolescent.
This is because the inner pulp, the focus of the treatment, plays an important role in a young tooth’s development. When it first erupts a tooth’s dentin layer, the living tissue that makes up most of the body and roots of the tooth, hasn’t fully formed. The pulp increases the dentin layer over time in conjunction with jaw development.
Because a full root canal treatment removes all of the pulp tissue, it could interrupt any remaining dentin development in a young tooth. This could lead to poorly-formed roots and a less healthy tooth. For an immature permanent tooth, then, we would use variations of a root canal treatment depending on the nature and extent of the injury, the patient’s overall health and medications they may be taking.
Our main objective is to expose or remove as little of the pulp tissue as possible when treating the tooth. If the pulp hasn’t been exposed by the decay or injury, we may only need to remove the softened decayed or injured dentin while leaving harder dentin nearer the pulp intact. If, however, the pulp has become partially exposed by disease or injury, we would then perform a pulpotomy in which we remove only the exposed tissue and then place calcium hydroxide or mineral trioxide aggregate (MTA) to stimulate dentin growth that will eventually patch the exposure site.
In cases where decay or injury has rendered an immature tooth’s pulp tissue unsalvageable, we may use a procedure known as apexification that seals off the open, cylindrical root end of the tooth. This will allow bone-like tissue to grow around the root to serve as added support for the tooth. Although it can save a tooth in the short run, the tooth’s long-term survival chances may be lower.
By using these and other techniques we may be able to save your child’s immature tooth. At the very least, such a technique could postpone replacing the tooth until a more opportune time in adulthood.

Our main focus as your dentist is to keep your teeth and gums healthy and functional. But there’s another important aspect of care — your teeth’s appearance. It’s not just a superficial concern: your smile can have a profound effect on your self-image, as well as your personal and professional relationships.
This is the realm of cosmetic dentistry: served by both specialists and general dentists, it focuses on altering your teeth’s appearance with treatments as basic as teeth whitening or as comprehensive as dental implants. The goal, however, is the same: a new, more attractive smile.
In a way, cosmetic dentistry begins with you and oral hygiene. The twin tasks of brushing and flossing to remove dental plaque not only lowers your risk for tooth decay or periodontal (gum) disease, they also improve the appearance of the tooth surface. There are, however, circumstances where otherwise healthy or repaired teeth may need extra cosmetic attention due to chipping, misshape or staining. In these cases, a truly cosmetic approach may be necessary.
One approach is to cover a tooth’s blemishes. Veneers, for example, are thin, layered pieces of dental porcelain shaped and colored like natural teeth that are bonded to the outside of an unattractive tooth. In other cases, a tooth may require a life-like porcelain crown that completely covers it to gain the same effect.
Missing teeth, of course, pose a different challenge, but here there are a wide range of solutions: dental implants, fixed bridgework or removable full or partial dentures. Advancements in dental materials and techniques can produce new teeth that are so life-like and natural that they’re imperceptible from the real thing.
Â These and other measures like orthodontics can all be used to turn a smile you find embarrassing into one you’re confident to share with the world. It begins, though, with both you and us taking a good, close look at your current smile — a smile analysis, if you will.
After assessing both your current needs and your expectations for change, we can develop an appropriate treatment plan. It might be quite simple or with multiple treatment stages, but it will be the best plan for you. Through cosmetic dentistry we have the means to help you achieve a new, more confident smile.

Most first-time root canal treatments achieve their purpose in saving an internally decayed tooth and extending its life to match those of the patient’s non-decayed teeth. Occasionally, though, a root canal-treated tooth may become re-infected by decay.
There are a number of reasons for this: the permanent crown meant to add further protection against decay may have been delayed, giving bacteria an opening to re-infect the tooth; it’s also possible the original seal for the pulp chamber and root canals after filling wasn’t sufficient to prevent bacterial contamination.
There‘s also another reason that’s very difficult to foresee — the presence of narrow, curved root canals in the tooth that can pose complications during the procedure. Some of these known as accessory or lateral canals branch off the main canals to create a complex network that’s difficult to detect during the initial procedure. If they’re not cleaned out and filled during the procedure any tissue trapped in them can remain infected and ultimately die. If these canals also open into the periodontal membrane at the attachment between the teeth and bone, the infection can spread there and become a periodontal (gum) infection that can trigger future tooth loss.
Fortunately, a reoccurrence of infection isn’t necessarily a death sentence for a tooth. A second root canal treatment can correct any problems encountered after the first treatment, especially complications from accessory canals. It may, though, require the advanced skills of an endodontist, a dental specialist in root canal problems. Endodontists use microscopic equipment to detect these smaller accessory canals, and then employ specialized techniques to fill and seal them.
If you encounter pain or other signs of re-infection for a tooth previously treated with a root canal procedure, contact us as soon as possible. The sooner we can examine and diagnose the problem, the better your tooth’s chances of survival by undergoing a second root canal treatment.

Stained teeth can be embarrassing — so much so you may even hesitate to smile. Before you seek out a whitening solution, though, there are a few things you need to know about tooth staining.
Tooth staining is more complex than you might think. There are actually two types: extrinsic, staining from foods and other substances of the outer surface of the enamel; and intrinsic, discoloration deep within a tooth that affects their outward appearance. The latter staining has a number of causes, including the type of dental materials used to fill a tooth, a history of trauma or the use of the antibiotic tetracycline during early tooth development.
There are some noticeable differences between the two types, although an examination is usually necessary to determine which you have. Extrinsic staining tends to be brown, black, or gray, or occasionally green, orange or yellow. Intrinsic staining can be red, pink or, if caused by tetracycline and fluoresced under ultraviolet light, yellow. If only one tooth is discolored it’s most likely intrinsic due to decay in the tooth pulp.
What can be done also depends on which type. Extrinsic staining can be modified through whitening, with either an office application or a home kit (there are differences, so you should consult with us before you decide). It may also be essential to modify your diet by restricting foods and beverages (coffee, wine or tea) known to cause staining and by eliminating tobacco use. You should also practice daily hygiene, including brushing with a toothpaste designed to diminish staining, and regular office cleaning and polishing.
Intrinsic staining can’t be addressed by these methods. Instead, you may need to undergo a procedure where we enter the interior of the tooth and insert a bleaching agent. If this isn’t an option, you can also choose a cosmetic restoration such as a porcelain veneer or crown that will cover the tooth to better match the color of your other teeth.
Dealing with stained teeth begins with a visit to our office to determine what type of discoloration you have and to learn your options. But regardless of what type you have, there is a way to a brighter smile.

A “gummy” smile, in which the upper gums are too prominent, is a common condition. There are several causes for gummy smiles — determining which one is the first step to having your appearance changed.
Although perceptions vary from person to person, most dentists agree a gummy smile shows 4 mm or more of gum tissue, and the amount is out of proportion with the length of the crown (the visible tooth). Teeth normally erupt through the gums during childhood and continue development until early adulthood, shrinking back from the tooth until stabilizing in place.
This typically produces a crown length of about 10 mm, with a “width to length” ratio of about 75-85%. But variations can produce differences in the relationship between teeth and gums and the width to length ratio of the teeth. The teeth may appear shorter and the gums more prominent. Worn teeth, caused by aging or grinding habits, may also appear shorter.
If tooth to gum proportionality is normal, then the cause may be upper lip movement. When we smile, muscles cause our lips to retract 6-8 mm from the lip’s resting position. If the amount of movement is greater (meaning the lip is hypermobile), it may show too much of the gums. The upper jaw can also extend too far forward and cause the gums to appear too prominent.
There are a number of ways to improve gummy smiles, depending on the cause. Periodontal plastic surgery known as crown lengthening removes and reshapes excess gum tissue to reveal more of the tooth. Lip hypermobility can be reduced with Botox injections (to paralyze the muscles) or in some cases with surgery to reposition the muscle attachments. Orthognathic surgery can be used to surgically reposition an overextended upper jaw. Other cosmetic enhancements such as orthodontics, bonding or porcelain restorations can also prove effective.
The first step is to obtain an accurate diagnosis for your gummy smile. From there, we can devise the best treatment approach to bring your smile back into a more attractive proportion.
