TimingisEverythingWhenReplacingaTeenagersMissingTooth

There are good reasons, for both health and appearance, to replace a missing tooth with a dental implant or similar restoration as soon as is practical. The bone around a tooth socket diminishes the longer it remains empty, up to 25% the first year. And, of course, your smile is less attractive, especially with a highly visible tooth.

If it’s your teenager, though, you may need to wait on a permanent restoration because their jaws are still developing. An implant placed before completion of jaw development could eventually appear out of alignment with neighboring teeth.

Our biggest concern is protecting bone health at the site of the missing tooth. We can do this and encourage growth by placing bone grafts (processed minerals from another donor) that serve as scaffolds on which surrounding bone can grow. Grafts usually dissolve (resorb) over time, but the rate of resorption can be slowed for a younger patient in need of long-term bone growth.

Planned orthodontic treatment can usually go on as scheduled. The orthodontist may accommodate the tooth loss by adding a temporary tooth within the braces or other device that matches the color and shape of the patient’s natural teeth. The orthodontist will also take care to maintain the empty space for a future implant or other restoration.

A dental implant is considered the best option for a missing tooth, not only for its life-like appearance and durability, but also its ability to encourage bone maintenance. Timing, though, is essential for teenagers. As it grows, the upper jaw will tend to move forward and down. Natural teeth move with this growth; implants, though, are attached differently and won’t move with the jawbone. While the other teeth around them move, the implants can appear to shrink back resulting in an unattractive smile appearance. So waiting until the jaw has finished growing is important.

For most people, jaw growth finishes by age twenty-one for men, women usually faster, but each person is different. The dentist’s expertise and experience, coupled with comparisons of adult family members’ facial appearances, will help determine the right time to undertake a permanent restoration for the best outcome both for health and a permanent, attractive smile.

NewFrontTeethforaTeenagedDavidDuchovny

In real life he was a hard-charging basketball player through high school and college. In TV and the movies, he has gone head-to-head with serial killers, assorted bad guys… even mysterious paranormal forces. So would you believe that David Duchovny, who played Agent Fox Mulder in The X-Files and starred in countless other large and small-screen productions, lost his front teeth… in an elevator accident?

“I was running for the elevator at my high school when the door shut on my arm,” he explained. “The next thing I knew, I was waking up in the hospital. I had fainted, fallen on my face, and knocked out my two front teeth.” Looking at Duchovny now, you’d never know his front teeth weren’t natural. But that’s not “movie magic” — it’s the art and science of modern dentistry.

How do dentists go about replacing lost teeth with natural-looking prosthetics? Today, there are two widely used tooth replacement procedures: dental implants and bridgework. When a natural tooth can’t be saved — due to advanced decay, periodontal disease, or an accident like Duchovny’s — these methods offer good looking, fully functional replacements. So what’s the difference between the two? Essentially, it’s a matter of how the replacement teeth are supported.

With state-of-the-art dental implants, support for the replacement tooth (or teeth) comes from small titanium inserts, which are implanted directly into the bone of the jaw. In time these become fused with the bone itself, providing a solid anchorage. What’s more, they actually help prevent the bone loss that naturally occurs after tooth loss. The crowns — lifelike replacements for the visible part of the tooth — are securely attached to the implants via special connectors called abutments.

In traditional bridgework, the existing natural teeth on either side of a gap are used to support the replacement crowns that “bridge” the gap. Here’s how it works: A one-piece unit is custom-fabricated, consisting of prosthetic crowns to replace missing teeth, plus caps to cover the adjacent (abutment) teeth on each side. Those abutment teeth must be shaped so the caps can fit over them; this is done by carefully removing some of the outer tooth material. Then the whole bridge unit is securely cemented in place.

While both systems have been used successfully for decades, bridgework is now being gradually supplanted by implants. That’s because dental implants don’t have any negative impact on nearby healthy teeth, while bridgework requires that abutment teeth be shaped for crowns, and puts additional stresses on them. Dental implants also generally last far longer than bridges — the rest of your life, if given proper care. However, they are initially more expensive (though they may prove more economical in the long run), and not everyone is a candidate for the minor surgery they require.

Which method is best for you? Don’t try using paranormal powers to find out: Come in and talk to us.

Modern dentistry has many ways to replace teeth and restore a clean, brilliant smile, and dental implants are one of the best available methods. Not only do they provide a cosmetically superior result, but they last the longest of all tooth restoration options, and are the Dental Implants most beneficial for maintaining jaw and oral health. Teeth aging is a fact of life, but with this cutting-edge technology, the care team here in St. Louis, MO can give you back the smile you once had. 

What Is Implant Dentistry?

The ‘implant’ refers to the method used to attach the denture into the mouth - instead of sitting on the gums or being attached to other teeth, a sturdy post, usually made of titanium or another bio-compatible material, is firmly set into the mandible (jaw bone). The bone actually grows around and secures the implant, giving it the long-lasting stability that dental implants provide for the prosthetic tooth. With a firm foundation in place, a custom-molded and color-matched denture can be attached for the most natural appearance and feel. 

What Does the Procedure Involve?

Implant placement involves a series of minor oral surgical procedures carried out at the Johnsons’ dental office. The first appointment involves burying the implant into the bone where the previously existing tooth root was. Usually local anesthesia is perfectly adequate, although other sedation options may be used depending on the patient.

After the post is placed, it needs time to heal. Over time, the bone rebuilds around the implant, a process called osseointegration. After this process has occurred, your dentist will be able to confirm that the implant has set correctly and attach the prosthetic denture at a second appointment. To place the denture, the implant site is re-exposed, and an abutment is attached to hold the prosthetic. 

What If I Need Multiple Teeth Replaced?

No problem! Dental implants can be used in multiple places for individual teeth, for whole sections needing replacement, or even for an entire denture set. 

Why Dental Implants?

Aside from the near-perfect cosmetic results and low maintenance, dental implants are better for your mouth. Root replacement keeps the surrounding bone from receding and weakening, as usually happens with a tooth is missing. Pressure on the gums from other forms of prosthetics can accelerate this process, and lead to a loose fit and slipping.
