Baby (primary) teeth look and function much like their permanent counterparts. Besides having a visible crown, they also have roots that maintain contact with the jawbone.
But there are some differences, the biggest one being the normal process whereby primary tooth roots dissolve or, in dental terms, resorb. Root resorption eventually leads to the tooth coming loose to make way for the permanent tooth.
Adult tooth roots can also resorb — but it's decidedly not normal. If adult root resorption isn't promptly treated, it could also lead to tooth loss — but there won't be an incoming tooth to take its place.
Although it can begin inside a tooth, adult root resorption usually begins on the outside. One type, external cervical resorption (ECR), begins around the neck-like area of the tooth not far below the gum line. Its initial signs are small pink spots where the tooth enamel has eroded; those pink cells within the space are doing the damage.
We don't fully understand the mechanism behind ECR, but there are some factors that often contribute. People with periodontal ligament damage or trauma, sometimes due to too much force applied during orthodontic treatment, have a high risk of ECR. Some bleaching techniques for staining inside a tooth may also be a factor.
The key to treating ECR is to detect it as early as possible before it does too much root damage. Regular checkups with x-rays play a pivotal role in early detection. Advanced stages of ECR might require more advanced diagnostics like a cone beam computed tomography (CBCT) scan to fully assess the damage.
If the lesion is small, we can surgically remove the cells causing the damage and fill the site with a tooth-colored filling. If ECR has spread toward the pulp, the tooth's inner nerve center, we may also need to perform a root canal treatment.
Either of these methods intends to save the tooth, but there is a point where the damage is too great and it's best to remove the tooth and replace it with a life-like dental implant or other restoration. That's why it requires vigilance through regular, semi-annual dental visits to detect the early signs of root resorption before it's too late.

While the sport of golf may not look too dangerous from the sidelines, players know it can sometimes lead to mishaps. There are accidents involving golf carts and clubs, painful muscle and back injuries, and even the threat of lightning strikes on the greens. Yet it wasn’t any of these things that caused professional golfer Danielle Kang’s broken tooth on the opening day of the LPGA Singapore tournament.
“I was eating and it broke,” explained Kang. “My dentist told me, I've chipped another one before, and he said, you don't break it at that moment. It's been broken and it just chips off.” Fortunately, the winner of the 2017 Women’s PGA championship got immediate dental treatment, and went right back on the course to play a solid round, shooting 68.
Kang’s unlucky “chip shot” is far from a rare occurrence. In fact, chipped, fractured and broken teeth are among the most common dental injuries. The cause can be crunching too hard on a piece of ice or hard candy, a sudden accident or a blow to the face, or a tooth that’s weakened by decay or repetitive stress from a habit like nail biting. Feeling a broken tooth in your mouth can cause surprise and worry—but luckily, dentists have many ways of restoring the tooth’s appearance and function.
Exactly how a broken tooth is treated depends on how much of its structure is missing, and whether the soft tissue deep inside of it has been compromised. When a fracture exposes the tooth’s soft pulp it can easily become infected, which may lead to serious problems. In this situation, a root canal or extraction will likely be needed. This involves carefully removing the infected pulp tissue and disinfecting and sealing the “canals” (hollow spaces inside the tooth) to prevent further infection. The tooth can then be restored, often with a crown (cap) to replace the entire visible part. A timely root canal procedure can often save a tooth that would otherwise need to be extracted (removed).
For less serious chips, dental veneers may be an option. Made of durable and lifelike porcelain, veneers are translucent shells that go over the front surfaces of teeth. They can cover minor to moderate chips and cracks, and even correct size and spacing irregularities and discoloration. Veneers can be custom-made in a dental laboratory from a model of your teeth, and are cemented to teeth for a long-lasting and natural-looking restoration.
Minor chips can often be remedied via dental bonding. Here, layers of tooth-colored resin are applied to the surfaces being restored. The resin is shaped to fill in the missing structure and hardened by a special light. While not as long-lasting as other restoration methods, bonding is a relatively simple and inexpensive technique that can often be completed in just one office visit.

About one American baby in 700 is born with some form of lip or palate cleft—and the percentage is even higher in other parts of the world. At one time this kind of birth defect sentenced a child to a lifetime of social stigma and related health issues. But thanks to a surgical breakthrough over sixty years ago, cleft defects are now routinely treated and repaired.
Oral and facial clefts happen because a child’s facial structure fails to develop normally during pregnancy. This causes gaps or “clefts” to occur in various parts of the mouth or face like the upper lip, the palate (roof of the mouth), the nose or (more rarely) in the cheek or eye region. Clefts can have no tissue fusion at all (a “complete” cleft) or a limited amount (an “incomplete” cleft), and can affect only one side of the face (“unilateral”) or both (“bilateral”).
There was little that could be done up until the early 1950s. That’s when a U.S. Navy surgeon, Dr. Ralph Millard, stationed in Korea noticed after reviewing a series of cleft photos that tissue needed to repair a cleft was most often already present but distorted by the defect. From that discovery, he developed techniques that have since been refined in the ensuing decades to release the distorted tissue and move it to its proper location.
This revolutionary breakthrough has evolved into a multi-stage approach for cleft repair that often requires a team effort from several dental and medical professionals, including oral surgeons, orthodontists and general dentists. The approach may involve successive surgeries over several years with dental care front and center to minimize the threat of decay, maintain proper occlusion (the interaction between the upper and lower teeth, or “bite”), or restore missing teeth with crowns, bridgework or eventually dental implants.
While it’s quite possible this process can span a person’s entire childhood and adolescence, the end result is well worth it. Because of these important surgical advances, a cleft defect is no longer a life sentence of misery.

If your teenager is in need of orthodontic treatment, you might automatically think braces. But while this decades-old appliance is quite effective, it isn’t the only “tooth movement” game in town any more. Clear aligners are another choice your teenager might find more appealing.
Clear aligners are a sequential set of computer-generated plastic trays that are worn by a patient one after the other, usually for about two weeks per tray. The trays are fabricated using 3-D computer modeling of the patient’s mouth, each one slightly different from the last to gradually move teeth to the desired new positions.
So, why choose clear aligners over braces?
They’re nearly invisible. Because they’re made of a clear polymer material, they’re not nearly as noticeable as metal braces. In fact, they may go completely unnoticed to the casual observer.
They’re removable. Unlike metal braces, which are fixed in place by an orthodontist, clear aligners can be removed by the wearer. This makes brushing and flossing much easier, and they can also be removed for eating or special occasions. That said, though, they should be worn at least 20 to 22 hours each day to be effective.
They’re becoming more versatile. With some complicated malocclusions (poor bites), braces and other orthodontic appliances may still be necessary. But innovations like added power ridges in clear aligners can more precisely control which teeth move and which don’t. This has greatly increased the number of poor bite scenarios where we can appropriately use clear aligners.
If you’d like to consider clear aligners, just remember they require a bit more self-discipline on the part of the wearer than braces. And once the treatment finishes, they’ll still need to wear a retainer just as with metal braces to help keep the repositioned teeth from reverting to their old positions.
If you think your teen is up to the challenge and their particular situation can be corrected with this innovative technology, then clear aligners could be a great choice.

Just like other parts of your physical body, teeth naturally wear as we get older. Just the effect from chewing during hundreds of thousands of meals in a lifetime can take its toll.
But there are some factors that can make tooth wear worse. By addressing them promptly should they arise, you can keep age-related tooth wear to a minimum.
Here are 3 areas to watch for to avoid excessive tooth wear.
Dental disease. Tooth decay and periodontal (gum) disease are most responsible for not only the loss of teeth but for compromising tooth health overall. But the good news is they’re largely preventable through proper oral hygiene practices to remove bacterial plaque, the main trigger for these diseases. Prompt treatment when they do occur can also minimize any damage and help your teeth and gums stay strong and healthy.
Your bite. Also known as occlusion, the bite refers to how the upper and lower teeth align with each other when you bite down. When they don’t align properly, regular chewing and biting can create abnormally high forces in the teeth and cause them to wear unevenly and more rapidly. Correcting the bite through orthodontic treatment won’t just improve your smile, it can improve bite function and decrease accelerated tooth wear.
Bruxism. This is a general term describing habits like teeth clenching and grinding in which the teeth forcefully contact each other beyond normal parameters. There are a number of causes for bruxism, but for adults it’s typically related to stress. Over time, bruxism can accelerate tooth wear and cause other problems like TMD. There are a number of ways to stop or at least reduce the effects of bruxism like relaxation techniques or a night guard worn during sleep that prevents the teeth from making forceful contact.
If you suspect you’re experiencing any of these factors, see us for a full examination. We’ll then be able to discuss your condition, the potential impact on tooth wear, and what we can do to protect your teeth.
