Children losing their primary (“baby”) teeth is both natural and necessary. So, is it really that much of a concern if they lose one early?
The answer is yes — premature primary tooth loss could have long-term consequences for the permanent teeth as they develop within the jaw before eruption. Primary teeth play a crucial role in this development: as the permanent teeth form and grow the primary teeth serve as placeholders until they’re ready to erupt. A natural process then takes place in which the primary tooth’s roots dissolve (resorb) to allow them to fall out. Once they’re out of the way, the permanent teeth can then erupt.
If, however, they’re lost before the permanent teeth are ready, it leaves a space in the child’s bite. The dynamic mechanism between teeth and the periodontal ligament causes adjacent teeth to move or “drift” into the space. This can crowd out the permanent tooth intended for the space, causing it to come in improperly forming a malocclusion (bad bite), or it may become impacted and remain partially or fully below the surface of the gums.
This poor dental development could lead to extensive orthodontic treatment later in life, which is why we seek to preserve even decayed primary teeth for their entire natural lifespan. If the tooth is lost, however, we need to take action to preserve the space for the permanent tooth and avoid costly treatment later.
This usually calls for a “space maintenance” appliance — a type of orthodontic “retainer” — worn by the child to prevent other teeth from drifting into the space. Designed by your orthodontist, the appliance can also perform a cosmetic and social function by causing the space to appear unnoticeable.
Maintaining that space requires monitoring — especially by an orthodontist — and continued dental hygiene and care both at home and at the dentist’s office. The extra care preserving the space caused by premature tooth loss will help to ensure your child’s dental structure develops properly and their future smile will be an attractive one.

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.

Porcelain veneers represent one of the best values in cosmetic dentistry, capable of radically changing a person’s smile with little tooth surface preparation. Still, the small amount of tooth enamel usually removed to accommodate them will permanently alter the affected teeth, to the point they will require a veneer or other restoration from then on.
The traditional veneer has remarkable versatility for solving a number of minor cosmetic problems, correcting mild tooth positioning problems and replacing lost or damaged enamel. But to avoid an unnatural bulky appearance, a portion of the tooth enamel must be permanently removed to accommodate them.
In recent years, though, a new concept known as “prepless veneers” has emerged in the field of cosmetic dentistry. Understandably, this new, “drill-free” veneer application has caused a lot of debate among dentists and patients alike, with concerns of bulky, overly-contoured teeth resulting from the technique. But the concept is growing as many well-regarded dentists have incorporated both minimal prep and prepless veneers into their service offerings.
The prepless veneer offers a cosmetic solution that doesn’t alter the tooth permanently. Using techniques such as feathering, which tapers and blends the veneer seamlessly with the tooth at the gum line, we can avoid an unnatural appearance while offering patients a much less invasive outcome.
The main disadvantage of prepless veneers at this time is that they’re not appropriate in every case. In fact, careful patient selection is a key to a successful outcome. For example, relatively large teeth or teeth positioned too far forward don’t work well with an added layer of thickness.
If, on the other hand, you have small, short or worn teeth, or teeth overshadowed by your lips — just to name a few likely scenarios — then you may benefit immensely from prepless veneers without permanent alteration to your teeth. A detailed examination is your first step to finding out if this new technique could provide you with a less-invasive smile makeover.

Before she began hosting the long-running TV competition Top Chef, Padma Lakshmi was a well-known model and successful cookbook author. (Appropriately, she is said to have been “discovered” by a modeling agent while sitting in a café in Madrid.) Yet the Indian-born beauty's striking look — at once exotic and familiar — doesn't come from any cookie-cutter mold.
So when Lakshmi had cosmetic work done on her teeth, early in her career, her dentist didn't use a cookie-cutter approach either: Instead, her smile was carefully designed, using small amounts of bonding material to brighten her teeth and to bring their shape and spacing into harmony with her facial features.
Dentistry by Design
What exactly is smile design — and what could it do for you? Essentially, it's the process of evaluating your smile in concert with the appearance of your entire face, and visualizing the changes — some dramatic and some subtle — that will make it really shine. Some aspects we consider include the face's shape, the proportion or “balance” of facial features, the complexion, eye and lip color and form, and the overall dimensions of the smile.
Based on dental aesthetics and clinical experience, we will probably have a number of suggestions to make on how you can improve your smile. Your input will also be very important; while some individuals prefer perfectly even teeth and a sparkling “Hollywood white” smile, others are looking for a result that's more in keeping with a “natural” look: slight irregularities in tooth shape, spacing, and even color.
There's no right or wrong answer here: Having a “perfect” smile means what's perfect for you, so it's very important for dentists and patients to communicate openly during the smile design process. But sometimes, words alone just aren't enough to convey the subtle dimensions of beauty.
The Trial Smile
Fortunately, it's now possible to preview your “perfect” smile using a number of different techniques. Advances in computer imaging make this the first step in previewing your new smile — you can see the changes before a single tooth is touched! Still, many people find that having a more concrete picture is helpful. The next step is to make a 3-D mock-up the proposed dental work on an actual model of your mouth. That way, you can see a physical representation of the final results — and even turn it around and hold it in your hands.
There's still one more way to really experience the difference cosmetic treatments can make without committing to a permanent change: the provisional restoration. Here, tooth-colored bonding material and other techniques are used to actually create the new smile — temporarily. This gives you time to “live with it,” and see if the proposed changes work for you. If everything goes well with the provisional work, the permanent restoration is guaranteed to please.
So if you want holiday treats, get out the cookie cutter — but if you're looking for a smile that's uniquely yours, and one that enhances your own individual appearance… call our office and ask about a smile design consultation.

So you’re tearing up the dance floor at a friend’s wedding, when all of a sudden one of your pals lands an accidental blow to your face — chipping out part of your front tooth, which lands right on the floorboards! Meanwhile, your wife (who is nine months pregnant) is expecting you home in one piece, and you may have to pose for a picture with the baby at any moment. What will you do now?
Take a tip from Prince William of England. According to the British tabloid The Daily Mail, the future king found himself in just this situation in 2013. His solution: Pay a late-night visit to a discreet dentist and get it fixed up — then stay calm and carry on!
Actually, dental emergencies of this type are fairly common. While nobody at the palace is saying exactly what was done for the damaged tooth, there are several ways to remedy this dental dilemma.
If the broken part is relatively small, chances are the tooth can be repaired by bonding with composite resin. In this process, tooth-colored material is used to replace the damaged, chipped or discolored region. Composite resin is a super-strong mixture of plastic and glass components that not only looks quite natural, but bonds tightly to the natural tooth structure. Best of all, the bonding procedure can usually be accomplished in just one visit to the dental office — there’s no lab work involved. And while it won’t last forever, a bonded tooth should hold up well for at least several years with only routine dental care.
If a larger piece of the tooth is broken off and recovered, it is sometimes possible to reattach it via bonding. However, for more serious damage — like a severely fractured or broken tooth — a crown (cap) may be required. In this restoration process, the entire visible portion of the tooth may be capped with a sturdy covering made of porcelain, gold, or porcelain fused to a gold metal alloy.
A crown restoration is more involved than bonding. It begins with making a 3-D model of the damaged tooth and its neighbors. From this model, a tooth replica will be fabricated by a skilled technician; it will match the existing teeth closely and fit into the bite perfectly. Next, the damaged tooth will be prepared, and the crown will be securely attached to it. Crown restorations are strong, lifelike and permanent.
Was the future king “crowned” — or was his tooth bonded? We may never know for sure. But it’s good to know that even if we’ll never be royals, we still have several options for fixing a damaged tooth.
