Accidents happen, especially to teenagers involved with sports or similar activities. In an instant they can lose one or more teeth and permanently alter their smile.
Fortunately we can restore a teenager’s lost teeth, but often not immediately as a permanent restoration with a dental implant requires maturity of their jaw structure. Our focus then turns to the age of the patient and the condition of the underlying bone. A future dental implant, your best choice for tooth replacement, depends on bone for support, but also the age of the patient as it relates to jaw development.
There are a couple of ways an accidental tooth loss can harm supporting bone: first and foremost, the impact of the accident itself can damage the bony socket. To find out for sure we may need to perform a cone beam scan, a type of x-ray that allows us to view the area three-dimensionally. If we do find damage, we can attempt to repair the socket through bone grafting.
Bone can also suffer from the long-term absence of a tooth. Bone has a growth cycle in which older cells dissolve and new ones form to take their place. The force generated by teeth when we eat or chew helps stimulate this growth. Without stimulation, as with a missing tooth, the bone may not grow at a healthy rate. In time, it could lose some of its volume and density and not be able to support an implant.
Installing an implant right after tooth loss could help avoid this situation. Bone has a natural affinity with the titanium post imbedded in the jaw and will naturally grow and adhere to it. But we can’t place an implant with a teenager. This is because the jaw is still developing so an implant would gradually become misaligned as the jaw grows. It’s best to install an implant later after full jaw development in early adulthood.
Today, we can place a bone graft in the empty socket right after tooth loss. The graft serves as a scaffold for bone cells to grow on and will help keep the bone volume at a healthy level until we can install an implant.
Timing is everything in restoring a teenager’s accidental tooth loss. But with coordination and care for the supporting bone, a teenager can eventually enter their adult years with their smile intact.

Dental implants have become the standard for long-term tooth replacement. From mechanics to movie stars, people from all walks of life have discovered the advantages of replacing a missing tooth with an implant. Obviously, restoring your smile is a definite advantage, but an implant can also help to maintain the health of your jawbone and adjacent teeth.
The implant is a small, screw-like titanium post that is placed into your jawbone to function as the root part of the tooth. The living bone tissue will actually attach to the titanium post, fusing them together. This will not only provide a sturdy anchor for a natural-looking crown, but will provide stability for bridgework or dentures. You will then be able to smile, chew and talk as if all of your teeth are natural. The procedure will also help to stabilize the bone, reducing long-term bone loss that occurs when a missing tooth is not replaced.
At this point, if you are thinking that there must be a lot of pain involved, I have good news for you. There is very little pain involved after the procedure is completed and no pain at all during the procedure. Typically, it is a routine surgery that takes place in a dentist’s office under local anesthesia where the immediate area is numbed. If there is any apprehension at all about the procedure, we will offer alternative anesthesia or sedation options during the planning process.
To determine who will be a good candidate for the implant procedure, a plan must be in place to assure the success of the implant. Part of the plan includes:
- Reviewing your past medical and dental history. We must know your complete past and present medical history and medication use, since good health is essential. There are certain conditions and diseases that can affect the healing of an implant.
- Performing a comprehensive dental examination. An evaluation of your dental problems and needs will determine if implants are in your best interests. An assessment of the health and mass of the jawbone as well as the number and location of the implant(s) that are needed to restore your bite and smile back to health will also be determined.
When the implant procedure has been successfully completed, there is one more step. As with your natural teeth, preventive maintenance is crucial for long-term success. A daily routine of brushing and flossing along with regular professional dental cleanings and checkups will help ensure continued gum health and proper functioning of your implants.

For generations, dentures have helped people avoid the dire consequences of total teeth loss. Now, implant technology is making them even better.
Composed of life-like prosthetic teeth fixed within a plastic or resin gum-colored base, dentures are manufactured to fit an individual patient’s mouth for maximum fit, comfort and performance. But dentures also have a critical drawback—they can’t stop bone loss in the jaw.
Bone is constantly regenerating as older cells dissolve and then are replaced by newer cells. In the jawbone, the forces generated when we chew travel through the teeth to the bone and help stimulate this new cell growth. When teeth are missing, though, the bone doesn’t receive this stimulus and may not regenerate at a healthy rate, resulting in gradual bone loss.
Dentures can’t transmit this chewing stimulus to the bone. In fact, the pressure they produce as they rest on top of the gums may actually accelerate bone loss. Over time then, a denture’s once secure and comfortable fit becomes loose.
In the past, most patients with loose dentures have had them relined with new dental material to improve fit, or have new dentures created to conform to the changed contours of the jaws. But implant technology now offers another alternative.
Implants are in essence a tooth root replacement. Dentists surgically implant a titanium metal post directly into the jawbone that naturally attracts bone cells to grow and adhere to it over time (a process called osseointegration). This not only creates a secure and lasting hold, it can also stop or even reverse bone loss.
Most people know implants as single tooth replacements with a porcelain crown attached to the titanium post. But a few strategically placed implants can also support either removable or fixed dentures. Removable dentures (also called overdentures) usually need only 3 or 4 implants on the top jaw and 2 on the bottom jaw for support through built-in connectors in the dentures that attach to the implants. A fixed bridge may require 4-6 implants to which they are permanently attached.
There are pros and cons for each of these options and they’re both more expensive than traditional dentures. In the long run, though, implant-supported dentures could be more beneficial for your bone health and hold their fit longer.
With a 95-plus percent survival rate after ten years, dental implants are one of the most durable replacement restorations available. Implants can potentially last much longer than less expensive options, which could make them a less costly choice in the long run.
But although a rare occurrence, implants can and do fail—often in the first few months. And tobacco smokers in particular make up a sizeable portion of these failures.
The reasons stem from smoking’s effect on oral health. Inhaled smoke can actually burn the outer skin layers in the mouth and eventually damage the salivary glands, which can decrease saliva production. Among its functions, saliva provides enzymes to fight disease; it also protects tooth enamel from damaging acid attacks. A chronic “dry mouth,” on the other hand, increases the risk of disease.
The chemical nicotine in tobacco also causes problems because it constricts blood vessels in the mouth and skin. The resulting reduced blood flow inhibits the delivery of antibodies to diseased or wounded areas, and so dramatically slows the healing process. As a result, smokers can take longer than non-smokers to recover from diseases like tooth decay or periodontal (gum) disease, or heal after surgery.
Both the higher disease risk and slower healing can impact an implant’s ultimate success. Implant durability depends on the gradual integration between bone and the implant’s titanium metal post that naturally occurs after placement. But this crucial process can be stymied if an infection resistant to healing arises—a primary reason why smokers experience twice the number of implant failures as non-smokers.
So, what should you do if you’re a smoker and wish to consider implants?
First, for both your general and oral health, try to quit smoking before you undergo implant surgery. At the very least, stop smoking a week before implant surgery and for two weeks after to lower your infection risk. And you can further reduce your chances for failure by practicing diligent daily brushing and flossing and seeing your dentist regularly for cleanings and checkups.
It’s possible to have a successful experience with implants even if you do smoke. But kicking the habit will definitely improve your odds.

Semi-annual office cleanings are important for keeping teeth healthy and disease-free. If you’ve replaced some of your teeth with dental implants, though, you may be thinking they don’t need as much attention from your hygienist.
It’s quite the opposite — cleaning around implants is important, and actually requires additional attention. The reason for this relates to both how dental implants attach to the jaw and their constructive materials.
Natural teeth are held in place by the periodontal ligament with tiny fibers that attach to the teeth on one side of it and to the jawbone on the other. The ligaments and the gingival (gum) fibers (which are also attached to the tooth) provide some disease resistance to the teeth through its rich blood vessel and collagen network. Dental implants, on the other hand, anchor directly into the jawbone. The titanium integrates with the bone, which naturally attracts to the metal and grows around it, which provides the implant’s eventual attachment strength. The implant doesn’t attach to the gum tissue and won’t develop the same relationship with the periodontal ligament as natural teeth.
Bacterial plaque, the primary cause for tooth decay and periodontal (gum) disease, can collect on an implant crown just as readily as on a natural tooth. Although the materials that make up an implant can’t be affected by a plaque-induced infection, the gum tissues and supporting bone around it can. In fact, because implants lack the disease resistance of the gingival fibers and the ligament attachment, an infection can turn rapidly into a condition known as peri-implantitis that could cause bone and tissue loss and lead to the loss of the implant.
Your hygienist understands the importance of removing plaque and calculus (hardened plaque deposits) from around your dental implant. This often calls for different instruments made of plastics or resins that won’t scratch the implant’s highly polished surface. Scratches provide a haven for bacteria to collect and make it more difficult to dislodge them. Likewise, if the hygienist uses ultrasonic equipment that loosens plaque through vibration, the hygienist will often use nylon or plastic tips to minimize damage to the implant.
And don’t forget your own personal hygiene habits — they’re just as important with dental implants as with natural teeth. Keeping plaque under control, both at home and with your dentist, is crucial to longevity for your dental implants.
