As tough as teeth are, life can take its toll on them and sometimes lead to parts of them chipping off. Although it might not affect a tooth's overall health, it can certainly downgrade its appearance.
But we can restore a chipped tooth like new, and it may not require extensive dental work. Thanks to a versatile dental material called composite resin, we can often bring back a tooth's natural appearance in just one visit.
Tooth-colored resins have been around for decades, but their application has been limited due to issues with durability. Recently developed bonding techniques, though, have made them a workable option for restoring mild to moderate tooth defects.
We do this by applying and bonding the composite resin to a tooth to “fill in” the missing portion. While it's often a short process, it does require a thorough understanding of tooth anatomy, function and aesthetics.
We begin with a comprehensive exam to assess the true condition of a chipped tooth. Some dental defects might be better served with a porcelain restoration like a veneer or crown for best results. Still, there are a wide range of defects for which composite resins is a solid repair choice.
Once we've determined bonding is appropriate, we prepare the tooth by first roughening its outer surface and then etching it with an acid solution to increase bonding strength. We then apply a luting agent, a kind of dental cement, also to aid with bonding.
We then begin applying the composite resin in liquid form, one layer at a time. This layering process helps simulate the color depth and shape of the tooth, and to further incorporate strength into the restoration. We're also careful at this point to match the variations of color with those of the surrounding teeth so that it looks as natural as possible.
As we finish each layer, we apply a curing light to harden the resin. We can then polish the finished product and make adjustments for the bite. The end result is a tooth that not only looks whole, but natural and blended with the rest of your teeth. Bonding could truly change your smile in just one visit.

Even though teeth are resilient, they're not indestructible. An accidental collision involving the face could damage teeth, even knocking a tooth completely out of its socket.
At first, it might seem like the end of the line for that particular tooth. But it doesn't have to be—if you know what to do. But you'll have to act quickly: The longer the tooth is out of its socket, the less chance it will survive long-term.
Here are the steps you should take to save a knocked-out tooth.
Find the tooth. It's important that you locate the missing tooth quickly. When you do, don't handle it by the root end: It still contains delicate periodontal cells that are essential if the tooth is going to rejoin with the ligaments and bone. Use clean water to rinse off any dirt or debris.
Reinsert the tooth. Holding it by the crown and not the root, reinsert the tooth into its empty socket, hopefully within an hour (the faster the better). You want to make sure it's good and snug, so apply a little force when you do this. Place some clean gauze or cloth between the tooth and its opposite on the other jaw, then have the person bite down and hold it in place.
Get immediate dental care. It's preferable to find a dentist as soon as possible (if not, then the nearest emergency medical facility). The dentist will x-ray the tooth to make sure it's positioned properly, and may adjust it further if necessary. They may also splint the tooth to adjacent teeth to help stabilize it until it fully reattaches with the jaw.
Again, time is of the essence—the quicker you can perform the above steps, the better the tooth's chances. Any delay could jeopardize the tooth's ability to reattach, or it could shorten its lifespan.
You can also get guidance on treating a knocked-out tooth and other dental emergencies with a free mobile app developed by the International Association of Dental Traumatology (IADT). Just look in your Android or IOS app store for ToothSOS.

Moving teeth through orthodontics may involve more than simply wearing braces. There are many bite conditions that require extra measures before, during or after traditional orthodontic treatment to improve the outcome.
One such measure is extracting one or more teeth. Whether or not we should will depend on the causes behind a patient's poor dental bite.
Here, then, are 4 situations where tooth extraction before orthodontics might be necessary.
Crowding. This happens when the jaw isn't large enough to accommodate all the teeth coming in. As a result, later erupting teeth could erupt out of position. We can often prevent this in younger children with space maintainers or a palatal expander, a device which helps widen the jaw. Where crowding has already occurred, though, it may be necessary to remove selected teeth first to open up jaw space for desired tooth movement.
Impacted teeth. Sometimes an incoming tooth becomes blocked and remains partially or fully submerged beneath the gums. Special orthodontic hardware can often be used to pull an impacted tooth down where it should be, but not always. It may be better to remove the impacted tooth completely, as well as its matching tooth on the other side of the jaw to maintain smile balance before orthodontically correcting the bite.
Front teeth protrusion. This bite problem involves front teeth that stick out at a more horizontal angle. Orthodontics can return the teeth to their proper alignment, but other teeth may be blocking that movement. To open up space for movement, it may be necessary to remove one or more of these obstructing teeth.
Congenitally missing teeth. The absence of permanent teeth that failed to develop can disrupt dental appearance and function, especially if they're near the front of the mouth. They're often replaced with a dental implant or other type of restoration. If only one tooth is missing, though, another option would be to remove the similar tooth on the other side of the jaw, and then close any resulting gaps with braces.
Extracting teeth in these and other situations can help improve the chances of a successful orthodontic outcome. The key is to accurately assess the bite condition and plan accordingly.
