Accidents can happen to your mouth, especially if you have an active lifestyle. For example, a sudden blow to the jaw while playing sports or exercising could result in a chipped tooth. And, while the internal tooth structure may be fine, the effect on your appearance can be disheartening.
Fortunately, we have techniques and materials to restore your smile after an injury. Bonding with composite resin is one such procedure: it’s ideal for mild to moderate chipping, especially in highly visible front teeth.
Composite resin is a dental material made of various substances mixed to match the color and texture of natural teeth. The composite is usually made of inorganic glass filler blended with a plastic-based matrix and joined together with a chemical “coupling” agent. The ratio of filler to matrix will depend on the type of tooth and damage — for example, back teeth, which encounter higher biting forces, require a composite with more filler for added strength.
To begin the procedure, we first prepare the damaged tooth by applying microscopic etchings (often with a chemical solution) that create tiny depressions or “undercuts”: these help create a seamless bond between the composite and the natural tooth. We then apply the composite in layers with a bonding agent, building up layer upon layer until we’ve achieved the desired shape for the tooth involved.
Bonding with composite resins doesn’t require much tooth preparation, can be placed quickly and is relatively inexpensive. Because of the wide spectrum of color possibilities, composite resins are superior to traditional amalgam (metal) restorations in creating a more life-like appearance. Its application, however, can be limited by the amount of tooth structure needing to be replaced: because it isn’t as strong as the tooth structure it replaces, the more tooth structure the bonded composite resin attempts to replace the less likely it can stand up over time to normal bite forces.
Still, composite resins are ideal for mild to moderate damage or disfigurement. If you’ve suffered such an injury, be sure to visit us to see if bonding with life-like composites is the right solution for restoring your smile.

Your son has fallen and hit his face against a hard surface. Not only is he in pain but now there is also a chip missing from his front tooth. He is worried that his smile will never be the same. What should you do?
Answer: If you can find that missing chip, sometimes we can bond the fragment back on to the tooth. The tooth should be evaluated and repaired as soon as possible, although in the absence of other signs and symptoms of injury, and if your child is not in acute pain, it can probably wait up to 12 hours.
If the fragment can't be found, then the tooth can be restored with tooth-colored filling materials, which are also physically bonded to the natural tooth. Done well, these “composite resin” fillings can last for years and look perfectly natural. They may eventually need to be replaced with something more permanent.
If the chipped tooth is a child's primary (baby) tooth rather than a permanent (adult) tooth, the treatment will be similar.
However, a blow to a tooth can cause damage to the pulp — the living tissue within the tooth, which can become infected and die. If the damage to a primary tooth is too extensive it may be better to remove it to avoid damage to an underlying and developing permanent tooth. A place-holding appliance called a space maintainer may be used. If it is a permanent tooth it may need root canal treatment.
If a tooth is not chipped but is loosened or tender to the touch, it may require temporary stabilization, called splinting, until it has healed. Sometimes no treatment is required. If there has been a fracture to the tooth's root (the part below the gum line) it may heal by itself, or it may require further treatment especially if it is a permanent tooth, depending on the individual situation.
It is important to evaluate teeth that have been hit or damaged as a result of injury to ensure that they remain healthy and functional. We will keep track of the tooth or teeth, with observation, x-rays when necessary and monitoring over time to make sure no permanent damage has been done.

Your son just crashed his skateboard and cracked a tooth, or maybe your daughter fell off the monkey bars at school and now has a chipped front tooth. For children, and some adults, repairing chipped or damaged teeth with tooth-colored restorative materials directly bonded to the teeth may be the perfect solution to restore their smiles.
What is Involved: Composite bonding is a technique that has been developed to correct chipped teeth and other minor dental imperfections. It may also be used to correct mild crookedness or gaps between teeth. The procedure requires the application of a tooth-colored composite resin material to the surfaces of teeth, which is then sculpted to the desired shape. It can be performed in a single visit for one or multiple teeth. The procedure usually takes between one and two hours, and the end result is a beautiful, natural-looking smile.
Advantages for Kids and Adults: Composite resin bonding is a good choice for kids and teens since their jaws are still growing and developing, and they may still be engaged in high-risk activities. After your child's teeth and jaws are fully developed, we can discuss options for more permanent restorations such as porcelain veneers or crowns. These require removal of more tooth structure, which could compromise the long-term health of your child's teeth if done too soon. Composite resin restorations, which bond straight to the teeth and require little to no tooth preparation or drilling are therefore a good option for fixing chipped teeth, and they're less expensive than choosing veneers.
Disadvantages: The longevity of composite resin restorations is related to how well you maintain your teeth. Many people can go for ten or fifteen years before they need to have the bonded resins repaired or replaced. Others will tend to stain and wear after only one or two years and will need some touch-up work.
Nearly every parent and caregiver has experienced that almost instantaneous sick feeling when they see that their child has been injured, especially when it is an injury to the mouth and teeth. For some, it is just a bloody lip; however, if the accident chipped a tooth, then you may have a completely different situation on your hands. If the nerve of the tooth has not been damaged, you needn't worry too much — a composite (plastic) tooth-colored restoration that is actually bonded to the tooth is an ideal material for repairing most broken or chipped teeth. See us as soon as possible to assess the extent of injury, so that proper and appropriate action can be taken.
An additional reason why bonding with composite resin may be the ideal choice for repairing a child's chipped tooth is that it can be custom created in virtually any shade so that it perfectly matches the damaged tooth and the surrounding teeth. It is also far less expensive than a crown, an important factor to consider when repairing a primary (baby) tooth that will eventually fall out to make room for a permanent tooth. If the injury is to a permanent tooth, a composite resin still may be ideal to use as a restoration until your child or teenager has stopped growing or playing contact sports. This is because your teenager may be too young for a more permanent restoration such as a crown or porcelain veneer.
An important, proactive step you can take to be prepared for the next time your child has a dental injury is to download Dear Doctor's Field-side Pocket Guide for Dental Injuries. This handy, quick reference guide is a must have for athletes, parents, caregivers, teachers, coaches or anyone who is often in an environment where a mouth injury is likely to occur. Knowing what to do and how quickly you must respond can make the critical difference between saving and losing a tooth.
