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.

While most dental problems are caused by disease or trauma, sometimes the root problem is psychological. Such is the case with bulimia nervosa, an eating disorder that could contribute to dental erosion.
Dental erosion is the loss of mineral structure from tooth enamel caused by elevated levels of acid in the mouth, which can increase the risk for decay and eventual tooth loss. While elevated acid levels are usually related to inadequate oral hygiene or over-consumption of acidic foods and beverages, the practice of self-induced vomiting after food binging by bulimic patients may also cause it. Some of the strong stomach acid brought up by vomiting may remain in the mouth afterward, which can be particularly damaging to tooth enamel.
It’s often possible to detect bulimia-related erosion during dental exams. The bottom teeth are often shielded by the tongue during vomiting, so erosion may be more pronounced on the unshielded upper front teeth. The salivary glands may become enlarged, giving a puffy appearance to the sides of the face below the ears. The back of the mouth can also appear red and swollen from the use of fingers or objects to induce vomiting.
Self-induced vomiting may not be the only cause for dental erosion for bulimics. Because the disorder causes an unhealthy focus on body image, bulimics may become obsessed with oral hygiene and go overboard with brushing and flossing. Aggressive brushing (especially just after throwing up when the tooth enamel may be softened) can also damage enamel and gum tissue.
Treatment must involve both a short — and long-term approach. Besides immediate treatment for dental erosion, a bulimic patient can minimize the effect of acid after vomiting by not brushing immediately but rinsing instead with water, mixed possibly with a little baking soda to help neutralize the acid. In the long-term, though, the eating disorder itself must be addressed. Your family doctor is an excellent starting point; you can also gain a great deal of information, both about eating disorders and treatment referrals, from the National Eating Disorders Association at their website, www.nationaleatingdisorders.org.
The effects of bulimia are devastating to mental and physical well-being, and no less to dental health. The sooner the disorder can be treated the better the person’s chance of restoring health to their mind, body — and mouth.

There are good reasons, for both health and appearance, to replace a missing tooth with a dental implant or similar restoration as soon as is practical. The bone around a tooth socket diminishes the longer it remains empty, up to 25% the first year. And, of course, your smile is less attractive, especially with a highly visible tooth.
If it’s your teenager, though, you may need to wait on a permanent restoration because their jaws are still developing. An implant placed before completion of jaw development could eventually appear out of alignment with neighboring teeth.
Our biggest concern is protecting bone health at the site of the missing tooth. We can do this and encourage growth by placing bone grafts (processed minerals from another donor) that serve as scaffolds on which surrounding bone can grow. Grafts usually dissolve (resorb) over time, but the rate of resorption can be slowed for a younger patient in need of long-term bone growth.
Planned orthodontic treatment can usually go on as scheduled. The orthodontist may accommodate the tooth loss by adding a temporary tooth within the braces or other device that matches the color and shape of the patient’s natural teeth. The orthodontist will also take care to maintain the empty space for a future implant or other restoration.
A dental implant is considered the best option for a missing tooth, not only for its life-like appearance and durability, but also its ability to encourage bone maintenance. Timing, though, is essential for teenagers. As it grows, the upper jaw will tend to move forward and down. Natural teeth move with this growth; implants, though, are attached differently and won’t move with the jawbone. While the other teeth around them move, the implants can appear to shrink back resulting in an unattractive smile appearance. So waiting until the jaw has finished growing is important.
For most people, jaw growth finishes by age twenty-one for men, women usually faster, but each person is different. The dentist’s expertise and experience, coupled with comparisons of adult family members’ facial appearances, will help determine the right time to undertake a permanent restoration for the best outcome both for health and a permanent, attractive smile.

Is a chipped tooth big news? It is if you’re Justin Bieber. When the pop singer recently posted a picture from the dental office to his instagram account, it got over 2.6 million “likes.” The snapshot shows him reclining in the chair, making peace signs with his hands as he opens wide; meanwhile, his dentist is busy working on his smile. The caption reads: “I chipped my tooth.”
Bieber may have a few more social media followers than the average person, but his dental problem is not unique. Sports injuries, mishaps at home, playground accidents and auto collisions are among the more common causes of dental trauma.
Some dental problems need to be treated as soon as possible, while others can wait a few days. Do you know which is which? Here are some basic guidelines:
A tooth that’s knocked out needs attention right away. First, try and locate the missing tooth and gently clean it with water — but avoid holding the tooth’s roots. Next, grasp the crown of the tooth and place it back in the socket facing the correct way. If that isn’t possible, place it between the cheek and gum, in a plastic bag with the patient’s saliva or a special tooth preservative, or in a glass of cold milk. Then rush to the dental office or emergency room right away. For the best chance of saving the tooth, it should be treated within five minutes.
If a tooth is loosened or displaced (pushed sideways, deeper into or out of its socket), it’s best to seek dental treatment within 6 hours. A complete examination will be needed to find out exactly what’s wrong and how best to treat it. Loosened or displaced teeth may be splinted to give them stability while they heal. In some situations, a root canal may be necessary to save the tooth.
Broken or fractured (cracked) teeth should receive treatment within 12 hours. If the injury extends into the tooth’s inner pulp tissue, root canal treatment will be needed. Depending on the severity of the injury, the tooth may need a crown (cap) to restore its function and appearance. If pieces of the tooth have been recovered, bring them with you to the office.
Chipped teeth are among the most common dental injuries, and can generally be restored successfully. Minor chips or rough edges can be polished off with a dental instrument. Teeth with slightly larger chips can often be restored via cosmetic bonding with tooth-colored resins. When more of the tooth structure is missing, the best solution may be porcelain veneers or crowns. These procedures can generally be accomplished at a scheduled office visit. However, if the tooth is painful, sensitive to heat or cold or producing other symptoms, don’t wait for an appointment — seek help right away.
Justin Bieber earned lots of “likes” by sharing a picture from the dental office. But maybe the take-home from his post is this: If you have a dental injury, be sure to get treatment when it’s needed. The ability to restore a damaged smile is one of the best things about modern dentistry.

Tooth decay is a highly destructive dental disease, responsible along with periodontal (gum) disease for most adult tooth loss. And we become even more susceptible to it as we get older.
One form of decay that’s especially prominent among senior adults is a root cavity. Similar to a cavity in the crown (visible tooth), this form instead occurs at or below the gum line in the roots. They happen mainly because the roots have become exposed due to gum recession, a common consequence of periodontal (gum) disease and/or brushing too hard.
Exposed roots are extremely vulnerable to disease because they don’t have the benefit of protective enamel like the tooth crown, covered instead with a thin and less protective mineral-like material called cementum. Normally, that’s not a problem because the gums that would normally cover them offer the bulk of the protection. But with the gums receded, the roots must depend on the less-effective cementum for protection against disease.
Although we treat root cavities in a similar way to those in the crown by removing decayed structure and then filling them, there’s often an added difficulty in accessing them below the gum line. Because of its location we may need to surgically enter through the gums to reach the cavity. This can increase the effort and expense to treat them.
It’s best then to prevent them if at all possible. This means practicing daily brushing and flossing to remove bacterial plaque, the thin, built-up biofilm on teeth most responsible for both tooth decay and gum disease. You should also visit your dentist at least twice a year for professional cleanings and advanced prevention methods like topical fluoride to strengthen any at-risk teeth.
You should also seek immediate treatment at the first sign of gum disease to help prevent gum recession. Even if it has occurred, treating the overall disease could help renew gum attachment. We may also need to support tissue regeneration with grafting surgery.
Root cavities are a serious matter that could lead to tooth loss. But by practicing prevention and getting prompt treatment for any dental disease, you can stop them from destroying your smile.
