Orthodontics, veneers and other cosmetic dental techniques can turn a less than perfect smile into a beautiful one—but not always very quickly. For example, porcelain veneers can take weeks from planning to installation, including the meticulous work of an outside dental lab to produce veneers that look natural as well as beautiful.
But you may be able to take advantage of another approach, one that often takes no more than a couple of dental visits. Called direct veneers, it's actually a process of bonding and sculpting life-like composite materials to teeth that are heavily stained, chipped or that contain tiny crevices called “craze lines.”
Unlike the similarly-named traditional method, direct veneers don't involve the creation of layered porcelain veneers fashioned by a dental lab. But this newer process is similar to the older one in that some of the enamel must be removed from the teeth in question to provide a suitable surface for the composite material to adhere. This alteration will be permanent, requiring a restorative covering on the treated teeth from then on.
Right before this preparation, though, a dentist typically makes an impression of the patient's mouth. This will be the basis for creating the procedural plan for the dental work, particularly a “trial smile” from similar composite material that can be applied to the patient's teeth before actual restoration work begins. This temporary application gives both patient and dentist an opportunity to visualize the final look, and make needed adjustments in color and shaping.
Once the work plan is finalized, the patient then returns for the actual restoration procedure. The dentist begins by applying and bonding the composite material to the prepared teeth. Then, using a drill and manual instruments, the dentist shapes and smooths the material into a tooth-like appearance that blends with other teeth. The procedure can take a few hours, but it can usually be completed during a single visit.
Although direct veneers may not last as long as porcelain veneers, the process is less costly and requires less time to complete. Direct veneers could be an economical solution for achieving a more attractive smile.

We Americans love our sports, whether as participants or spectators. But there's also a downside to contact sports like soccer, football or basketball: a higher risk of injury, particularly to the mouth and face. One of the most severe of these is a knocked out tooth.
Fortunately, that doesn't necessarily mean it's lost: The tooth can be reinserted into the empty socket and eventually return to normal functionality. But it must be done as soon as possible after injury. The more time elapses, the lower the chances of long-term survival.
That's because of how teeth are held in place in the jaw, secured by an elastic, fibrous tissue known as the periodontal ligament. When a tooth is knocked out some of the ligament's periodontal cells remain on the tooth's root. If these cells are alive when the tooth is reinserted, they can regenerate and reestablish attachment between the ligament and the tooth.
Eventually, though, the cells can dry out and die. If that has already happened before reinsertion, the tooth's root will fuse instead with the underlying bone. The tooth may survive for a short time, but its roots can eventually dissolve and the tooth will be lost.
Your window of opportunity for taking advantage of these live periodontal cells is only 5-20 minutes with the best chances in those earlier minutes. You should, therefore, take these steps immediately after an injury:
- Find the tooth, hold it by the crown (not the root end), and rinse off any debris with clean water;
- Reinsert the root end into the empty socket with firm pressure;
- Place clean gauze or cloth in the person's mouth between the tooth and the other jaw, and ask them to bite down gently and hold their bite;
- Seek dental or emergency medical care immediately;
- If you're unable to reinsert the tooth, place it quickly in a container with milk and see a dentist immediately.
You can also obtain an Android or IOS smartphone app developed by the International Association of Dental Traumatology called ToothSOS, which will guide you through this process, as well as for other dental emergencies. The quicker you act, the better the chances that the injured person's knocked out tooth can be rescued.

Often as children grow older, their participation in sports or similar activities increases. While generally encouraged, this greater activity does increase injury risk, especially to the mouth.
In fact, the late childhood to early adulthood demographic is the most prone portion of the population to incur dental injuries. To complicate matters, their dental development is often incomplete, posing a number of treatment obstacles for an injured tooth.
For example, the primary means for preserving an injured adult tooth is a root canal treatment: damaged or diseased tissue within the pulp, the tooth’s innermost layer, is removed and the empty chamber and root canals filled and sealed to prevent infection. But while a fully matured tooth can function without the nerves and blood vessels of the pulp, a developing tooth needs these tissues for continued tooth formation. Otherwise, tooth development can stall and cause problems later on.
The most common solution for younger teeth is to remove any damaged tooth structure without disturbing the pulp if at all possible followed by a filling. That’s contingent, though, on whether we find the pulp unexposed or undamaged—if it is, we’ll try to remove only damaged or diseased pulp tissue and leave as much healthy tissue intact as possible. To aid with healing and tissue re-growth, we may also place medicinal stimulators between the pulp and the filling.
Jaw development may also pose a challenge if the injured tooth is too far gone and must be removed. Our best choice is to replace it with a dental implant; but if we install the implant while the jaw is still growing, it may eventually appear out of place with the rest of the teeth. It’s best to postpone an implant until full jaw maturity in early adulthood.
In the meantime we could provide a temporary solution like a removable partial denture or a modified bonded bridge that won’t permanently alter nearby teeth. These methods can adequately restore the function and appearance of missing teeth until the jaw is mature enough for an implant.
While injuries with young permanent teeth do pose extra challenges, we have effective ways to address them. With the right approach, the outcome can be just as successful as with a mature tooth.
