ATeensMissingToothMayRequireaTemporaryReplacement

Besides reduced biting and chewing function, a missing tooth can cause an embarrassing inhibition to healthy social interaction. This can be especially so for teens who greatly value peer relationships and acceptance.

Be that as it may, we typically discourage a permanent replacement for teens with a missing tooth, particularly dental implants. While we value a patient’s psychological needs, the long-term effect on dental health may be too great to advise otherwise.

The effect we’re concerned with involves jaw growth and development. Although a person’s permanent teeth have usually all erupted by early adolescence, the jaws continue to grow until the late teens or early twenties. Natural teeth can adapt to this growth because the periodontal ligament that holds them in place allows for incremental tooth movement. The teeth move in response to jaw growth and are thus able to maintain their proper relationship and alignment in the jaw as growth occurs.

Dental implants, on the other hand, are imbedded into the jaw bone: they, therefore, can’t move like natural teeth and thus can’t adjust their position with jaw growth, particularly the upper jaw as it grows forward and down. This can result in the implants appearing as though they are left behind or retreat into the jaw. It can also affect the position of the gums and inhibit their growth around the implants.

It’s best then to hold off implants and other permanent restorations until the jaw has finished developing. That, however, isn’t always easy to determine: specialized x-ray diagnostics may help, but it’s not an exact science. Your input as a parent will also be helpful, such as whether you’ve noticed the end of growth spurts (not changing clothes or shoe sizes as often) or your child’s recent similarity in appearance to other adult members of your family. It thus becomes a judgment call, based on examination and experience, as to whether it’s safe to proceed with implants — and may require erring on the side of caution.

In the meantime, there are temporary restorations that can improve appearance while you wait for the appropriate time to undertake a permanent restoration. Two of the most useful are removable partial dentures (RPDs) or a bonded bridge, a less invasive form of the traditional bridge. With a proper assessment we can advise you on which option is your best choice.

Implant-SupportedDentures-aBetterFitwithExcessiveBoneLoss

Some patients who wear dentures face a kind of Catch-22: their denture fit may have loosened and become uncomfortable over time due to continued bone loss, yet the same bone loss prevents them from obtaining dental implants, a superior tooth replacement system to dentures.

But there may be a solution to this dilemma that combines the stability of implants with a removable denture. A set of smaller diameter implants — “mini-implants” — can support a removable denture with less bone than required by a conventional implant.

Like all living tissue, bone has a life cycle: after a period of growth, the older bone dissolves and is absorbed by the body, a process known as resorption. The forces generated when we bite or chew are transmitted by the teeth to the jawbones, which stimulates new bone formation to replace the resorbed bone. When the teeth are lost, however, the stimulation is lost too; without it, resorption will eventually outpace bone growth and repair, causing the bone mass to shrink.

Removable dentures also can’t supply the missing stimulation — bone loss continues as if the dentures weren’t there; and due to the compressive forces of a denture, bone loss accelerates. As the jawbone structure used to originally form the denture’s fit eventually shrinks, the denture becomes loose and difficult to wear. It’s possible to adjust to the new jaw contours by relining the dentures with new material or creating a new set of dentures that match the current bone mass. Without adequate bone, fixed crowns or bridges anchored by conventional implants may also be out of the picture.

On the other hand, mini-implants with their smaller diameter need less bone than the traditional implant. A few strategically placed within the jaw are strong and stable enough to support a removable denture. One other advantage: these mini-implants can be installed in one visit with local anesthesia and usually without the need for incisions or stitches.

DontBreakItLikeBeckham

During his former career as a professional footballer (that's a soccer star to U.S. sports fans) David Beckham was known for his skill at “bending” a soccer ball. His ability to make the ball curve in mid-flight — to avoid a defender or score a goal — led scores of kids to try to “bend it like Beckham.” But just recently, while enjoying a vacation in Canada with his family, “Becks” tried snowboarding for the first time — and in the process, broke one of his front teeth.

Some fans worried that the missing tooth could be a “red card” for Beckham's current modeling career… but fortunately, he headed straight to the dental office as soon as he arrived back in England. Exactly what kind of treatment is needed for a broken tooth? It all depends where the break is and how badly the tooth is damaged.

For a minor crack or chip, cosmetic bonding may offer a quick and effective solution. In this procedure, a composite resin, in a color custom-made to match the tooth, is applied in liquid form and cured (hardened) with a special light. Several layers of bonding material can be applied to re-construct a larger area of missing tooth, and chips that have been saved can sometimes be reattached as well.

When more tooth structure is missing, dental veneers may be the preferred restorative option. Veneers are wafer-thin shells that are bonded to the front surface of the teeth. They can not only correct small chips or cracks, but can also improve the color, spacing, and shape of your teeth.

But if the damage exposes the soft inner pulp of the tooth, root canal treatment will be needed to save the tooth. In this procedure, the inflamed or infected pulp tissue is removed and the tooth sealed against re-infection; if a root canal is not done when needed, the tooth will have an increased risk for extraction in the future. Following a root canal, a tooth is often restored with a crown (cap), which can look good and function well for many years.

Sometimes, a tooth may be knocked completely out of its socket; or, a severely damaged tooth may need to be extracted (removed). In either situation, the best option for restoration is a dental implant. Here, a tiny screw-like device made of titanium metal is inserted into the jaw bone in a minor surgical procedure. Over time, it fuses with the living bone to form a solid anchorage. A lifelike crown is attached, which provides aesthetic appeal and full function for the replacement tooth.

So how's Beckham holding up? According to sources, “David is a trooper and didn't make a fuss. He took it all in his stride." Maybe next time he hits the slopes, he'll heed the advice of dental experts and wear a custom-made mouthguard…
