Children have a lot of energy that's often channeled through physical activities and sports. Unfortunately, this also increases their risk of injuries, particularly to their teeth.
Injuries to the mouth can endanger permanent teeth's survival. For an older tooth, a root canal treatment might be in order. Not so, though, for a pre-adolescent tooth, even if it is permanent.
A young permanent tooth is still developing dentin, the large layer just below the enamel. This growth depends on the connective tissue, blood vessels and nerves within the pulp in the center of the tooth. Because a root canal treatment removes all of this tissue, it could stunt dentin and root growth and endanger the tooth's future.
Instead, we may need to treat it with one of a number of modified versions of a root canal, depending on what we find. If the tooth's pulp is unexposed, for example, we may need only to remove the damaged dentin, while still leaving a barrier of dentin to protect the pulp. We then apply an antibacterial agent to minimize infection and fill in the area where we've removed tooth structure.
If some of the pulp is exposed, we may perform a pulpotomy to remove just the affected pulp and any overgrown tissue. We then place a substance that encourages dentin growth and seal it in with a filling. If we go deeper toward the root end, we might also perform procedures that encourage the remaining pulp to form into a root end to stabilize the tooth.
If the entire pulp has been damaged beyond salvage, we may then turn to a procedure called an apexification. In this case we clean out the pulp chamber; at the root end we place mineral trioxide aggregate (MTA), a growth stimulator that encourages surrounding bone to heal and grow. We then fill in the root canals and chamber with a special filling called gutta percha to seal the tooth.
The deeper we must penetrate into the pulp, the higher the chances the young tooth's dentin and roots won't form properly, leading to later problems and possible loss. But by employing the appropriate one of these methods, we can minimize the risk and give your child's damaged tooth a fighting chance.

A loose adult tooth isn't normal. It could be loose because it's been subjected to high biting forces like those that occur with a tooth grinding habit. Or, it could be the result of periodontal (gum) disease or some other infection that has weakened some of the tooth's supporting gums and bone. Whatever the underlying cause, we'll need to act quickly to save your tooth.
Our first step is to find out this exact cause—that will determine what treatment course we need to follow. For a tooth grinding habit, for example, you might need to wear an occlusal guard or have your bite (teeth) adjusted. With gum disease, we'll focus on removing dental plaque, the thin film of bacteria and tartar (calculus) fueling the infection. This stops the infection and minimizes any further damage.
While we're treating the cause, we may also need to secure the loose tooth with splinting. This is a group of techniques used to join loose teeth to more stable neighboring teeth, similar to connecting pickets in a fence. Splinting can be either temporary or permanent.
Temporary splinting usually involves composite materials with or without strips of metal to bond the loose tooth to its neighbors as the periodontal structures heal. Once the tooth's natural attachments return to health, we may then remove the splint.
There are a couple of basic techniques we can use for temporary splinting. One way is to bond the splint material to the enamel across the loose tooth and the teeth chosen to support it (extra-coronal splinting). We can also cut a small channel across all the affected teeth and then insert metal ligatures and bond the splint material within the channel (intra-coronal).
If we're not confident the loose tooth will regain its natural gum attachment, we would then consider a permanent splint. The most prominent method involves crowning the loose tooth and supporting teeth with porcelain crowns. We then fuse the crowns together to create the needed stability for the loose teeth.
Whatever splinting method we use, it's important to always address the root cause for a tooth's looseness. That's why splinting usually accompanies other treatments. Splinting loose teeth will help ensure your overall treatment is successful.

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.

Even with modern prevention and treatment advances, losing teeth in later life is still a sad but common part of human experience. Just as generations have before, many today rely on dentures to regain their lost dental function and smile.
But although effective, dentures have their weaknesses. The most serious: they can't prevent jawbone deterioration, a common problem associated with tooth loss.
Bone health depends on chewing forces applied to the teeth to stimulate replacement growth for older bone cells. When teeth are gone, so is this stimulation. Dentures can't replicate the stimulus and may even accelerate bone loss because they can irritate the bone under the gums as they rest upon them for support.
But there's a recent advance in denture technology that may help slow or even stop potential bone loss. The advance incorporates implants with dentures to create two hybrid alternatives that may be more secure and healthier for the supporting bone.
The first is known as an overdenture, a removable appliance similar to a traditional denture. But instead of deriving its support from the gums alone, the overdenture attaches to three to four implants (or only two, if on the lower jaw) that have been permanently set into the jawbone. This not only increases stability, but the implants made of bone-friendly titanium attract and foster increased bone growth around them. This can help slow or even stop the cycle of bone loss with missing teeth.
The second type is a fixed denture. In this version, four to six implants are implanted around the jaw arch. The denture is then secured in place to these implants with screws. It's a little more secure than the overdenture, but it's also more expensive and requires good quality bone at the implant sites.
If you've already experienced significant bone loss you may first need bone grafting to build up the implant sites for these options, or choose traditional dentures instead. But if you're a good candidate for an implant-supported denture, you may find it provides better support and less risk of continuing bone loss than traditional dentures.

Periodontal (gum) disease is a bacterial infection, which if left untreated could cause gum recession, bone loss and eventually tooth loss. Caused mainly by plaque left on tooth surfaces from poor hygiene practices, the deeper the infection spreads below the gum line, the more difficult it is to treat.
One possible scenario involves parts of a tooth’s root structure known as furcations. These are branching forks formed during the early development of teeth with multiple roots where they take different paths from the base of the crown. As gum disease spreads around the root it may cause different degrees of bone loss at the point of the branch.
It’s imperative when treating gum disease to uncover and remove any bacterial plaque or calculus (hardened plaque deposits) found, including below the gum line. To address bacterial plaque at the root level, it’s important to first determine if bone loss has involved the furcations (where the roots separate, also referred to as a “furcation invasion”) and to what degree.
We usually classify this degree of involvement in three classes: Class I, the invasion has created a groove in the furcation, but minimal significant bone loss; Class II, the bone loss has extended into the furcation by at least two millimeters; or Class III, the bone loss extends completely from one end of the furcation to the other (or “through and through”).
Depending on the class, cleaning plaque and calculus from furcations and then maintaining them thereafter can be quite challenging. We may need to use specially shaped hand instruments known as scalers or curettes to reach and clean root surfaces, or ultrasonic scalers that use high-frequency vibrations and streaming water to loosen and flush away plaque debris. It may also prove helpful, though limited, to apply antimicrobials or antibiotics to the area to help limit the levels of bacteria.
Disease damage around furcations may also require surgical treatment to encourage new tissue and bone growth in the area. Surgery can also help make the area more accessible to future cleaning and maintenance, both for you and us. Renewed hygiene practices on your part and regular cleaning and checkups with us will help ensure that the situation involving your tooth roots can be kept under control and your tooth preserved for many years to come.
