Losing a tooth can be traumatic, but a dental implant can dramatically turn that experience around. Providing functionality, life-like appearance and durability, implants stand out as the premier restoration for lost teeth.
For adults, that is. An older child or teenager with a missing tooth may need to wait a few more years for an implant. The reason: jaw development. A person's jaws, particular the upper jaw, continue to grow with most growth completed by early adulthood. Natural teeth with their periodontal attachments develop right alongside the jaw.
But because an implant attaches directly to the jawbone, its position is fixed: it won't change as the jaw grows and may gradually appear to sink below the gum line. That's why we wait to place an implant until most of jaw maturity has occurred after full jaw maturity. For females, we try to wait until 20 years of age and for males, usually 21 years of age. These are guidelines as some people mature faster and some slower, so a discussion with your dentist or surgeon is necessary to make an educated decision.
While we wait, we can install a temporary replacement for a child's or teenager's lost tooth, usually a partial denture or fixed modified ("Maryland") bridge. The latter affixes a prosthetic (false) tooth in the missing tooth space by attaching it to the back of natural teeth on either side with bonded dental material. It differs from a traditional bridge in that these supporting teeth aren't permanently altered and crowned to support the bridge.
During the time before implants we should understand that the area where the implant will be placed will undergo some bone deterioration, a common consequence of missing teeth. Forces generated as we chew travel through the teeth to stimulate renewing bone growth all along the jawbone. But with a lost tooth the chewing stimulation ceases at that part of the bone, slowing the growth rate and leading to gradual bone loss.
Fortunately, the titanium posts of dental implants stimulate bone growth as bone cells naturally grow and adhere to their surfaces. Before then, though, if the bone volume is diminished, we may need to graft bone material to stimulate bone growth that will enlarge the jaw bone enough for an implant to be placed.
It usually isn't a question of "if" but "when" we can provide your child with an implant for their missing tooth. In the meantime, we can prepare for that day with a temporary restoration.

X-ray imaging is such an intricate part of dentistry, we usually don't think twice about it. Without it, though, the fight against dental disease would be much harder.
At the same time, we can't forget that x-rays are a form of electromagnetic radiation that can penetrate human tissue. It's that very quality and the difference in the absorption rate between denser bone and teeth and softer diseased tissue that makes disease diagnosis possible.
But this same penetrative power can potentially harm the tissues it passes through. For that reason when practicing any form of x-ray diagnostics, dentists follow a principle known as ALARA, an acronym for "As Low As Reasonably Achievable." In lay terms ALARA means getting the most benefit from x-rays that we can with the lowest dose and exposure time possible.
While practicing ALARA with x-rays is important for patients of any age, it's especially so for children who are more sensitive to radiological energy given their smaller size and anatomy. We can't use the same settings, dosages or exposure times with them as with an adult.
To protect children, dentists have developed techniques and protocols that lessen their exposure time and rate, while still providing usable images for diagnosing disease. The bitewing is a good example of safe and effective pediatric x-ray imaging.
A bitewing is a plastic device holding exposable film that patients bite down on and hold in their mouth while x-raying. The x-rays pass through the teeth and gums and expose the film behind them on the bitewing. Using a bitewing we can capture a set of two to four radiographs to give us a comprehensive view of the back teeth, while exposing the child less radiation than they normally receive daily from background environmental sources.
This and other advances in equipment and digital imaging greatly reduce the amount of radiation patients receive during x-rays. If, though, you're still concerned about your child's x-ray exposure, talk with your dentist who can explain in more detail the x-ray safety protocols they follow. Just like you, they want your child to be as safe as possible while still benefiting from the diagnostic power of x-rays.

Teenagers and adults alike can improve their smile appearance with dental solutions like teeth whitening or orthodontics. But there are a few cosmetic solutions like porcelain veneers that are better suited for more mature teeth.
Veneers are composed of thin layers of dental porcelain that are bonded to the outside of teeth. They're kind of a tooth "mask" that hides blemishes like chips, discoloration or mild bite problems. They're often less involved and expensive than other types of dental restoration.
Even so, we usually need to remove some of the natural tooth's enamel before applying them. Veneers placed directly on unprepared teeth can appear bulky, so we remove some of the enamel to create a more natural look. And although usually only a slight amount, the alteration is permanent and will require the tooth to have some form of restoration from then on.
This usually doesn't pose a major issue for adults, but it could for a teenager's younger teeth. The nerve-filled dentin in a teenager's still developing tooth is thinner and closer to the pulp (nerve tissue) than in more mature teeth.
There's at least one situation, though, where veneers might be applied safely to a teenager's teeth without this concern. If the teen has abnormally small teeth and are receiving veneers to improve their appearance, they might not need alteration. Because the teeth are already thinner than normal, the "no-prep" veneers may not look bulky when directly bonded to them without preparation.
With most cases, though, it might be best to pursue other options that at the very least can make a cosmetic difference until their teeth are mature enough for veneers. For example, we might be able to repair chipped areas with composite resin material that we form and bond to the tooth to achieve a life-like appearance.
We can discuss these and other options for safely improving your teenager's smile. The important thing is to achieve a more confident appearance without endangering their future health.
