People have depended on dentures for generations—and they still do. That's because they work, both in restoring dental function and a smile marred by missing teeth.
But they have one major drawback related to bone health. That's because living bone has a life cycle: as older cells die, new ones form to take their place. The pressure generated when we chew stimulates this growth. But when this stimulus goes missing along with the teeth, the cell replacement rate slows and bone volume and density gradually diminishes.
Traditional dentures can't transmit this chewing pressure stimulus. And because they rest directly on the gum ridges, they can adversely affect the underlying bone and actually accelerate bone loss.
But implant technology potentially solves this bone loss problem with dentures by using implants rather than the gums to support them. It's a two-fold benefit: first, the implants relieve much of the irritation to the gums and bone caused by traditional dentures. Primarily, though, the implants themselves can slow or even stop continuing bone loss.
Most implants are made of titanium, not only because it's compatible with the body, but also because it has an affinity with bone. Over time bone cells grow on the titanium post imbedded in the jawbone. This process not only creates stability and durability, it can improve bone health.
In recent years dentists have incorporated implants with dentures to create two exciting treatment options. With one option, the dentist installs two or more implants in the jaw, to which a specially fitted removable denture can be attached. You would still have the ease of removing the denture for cleaning, while gaining greater stability and a reduced risk of bone loss.
The other option is a fixed denture (or bridge) attached permanently to implants. For this option, a patient's jawbone must be adequate and healthy enough to support at least four to six implants. A fixed denture is also often costlier and more complex than a removable denture, but it can feel more like real teeth. It also promotes better bone health too.
Although both options are more expensive than traditional dentures, they can pay dividends for long-term dental health. Implants could help you enjoy your new dentures and resulting smile for a long time to come.

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.

While many people still consider dental implants the "new kids on the block" in dental restoration, they're now in their fourth decade of use. And since their inception implant technology has continued to improve and revolutionize how we replace missing teeth.
Implants are a different "species" compared to other restoration methods. To be precise, an implant is a tooth root replacement—usually a titanium metal post imbedded directly into the jaw bone. Titanium is not only a biocompatible metal, but bone cells naturally grow on its surface to create a strong and durable hold. It's this secure hold that's most responsible for implants' high long-term success rate.
But we should also credit some of this success to the steady stream of advances over the years in implant construction and supporting technologies. For one thing, we're now more accurate and precise with implant placement thanks to advances in computer tomography (CT) and cone beam CT (CBCT) scanning.
These digital processes merge a series of images taken by a special camera to form a three-dimensional model of the jaw. We can manipulate this model on a computer monitor to view it from different vantage points. It can help us locate and avoid anatomical structures like nerves and sinuses when determining where to place a future implant. CT and CBCT are especially useful when there's a concern about adequate available bone, a necessity for stable implants.
Technology has also improved how we create surgical guides, often used during implant surgery to obtain the most accurate results. Surgical guides are custom-made devices that fit over the teeth with the drilling locations for the implants marked on them. Recent advances in 3-D printing have made these guides even more accurate so that they fit more securely in the mouth. This greater stability increases their accuracy during the drilling sequence during surgery.
These and other advances are helping ensure every implant is a success story. The end result is both a functional restoration and a beautiful smile.

Your dentures have served you well over the years. Lately, though, you’ve noticed the fit loosening in the lower denture. It’s not a new problem: you’ve had them refitted a few times already. But now it seems to be growing worse and you’re having more trouble chewing food or speaking clearly.
The problem isn’t all wear and tear with your dentures — the bone in your jaw is shrinking. A denture applies forces that are compressive. Natural teeth produce forces when we chew that travel through the tooth root and stimulate the bone to grow. Without teeth, there’s no such force to stimulate the bone. As a result, new bone cells don’t replace older cells at a healthy rate and bone volume diminishes over time. Because traditional dentures are supported by the gum ridges, the constant compressive forces on the gums can also contribute to bone loss.
As mentioned, we can refit dentures by lining them with new acrylic material. Eventually, though, it may be necessary to consider a new set of dentures that match the altered contours of your jaw. But continuing bone loss might lead to the same fate for your new dentures as your previous pair.
There’s a relatively new alternative, though, that could provide greater denture stability and help deter bone loss: implant overdentures. They’re actually a union between a traditional denture and a dental implant, a tooth replacement approach introduced over thirty years ago.
With this option, two strategically-placed implants are surgically inserted into the jaw bone. We then manufacture a denture (or retrofit your current dentures, if possible) with fittings that connect to the implants. Once in the mouth, the dentures gain their main support from the implants rather than the gum ridge, which relieves pressure on the bone. And because the titanium implant has a natural affinity with bone, new bone will grow and attach itself to it, increasing its stability and stopping bone loss.
Although more expensive than traditional dentures, implant overdentures are more affordable than individual teeth replaced by implants and are very cost-effective over time. What’s more, they can restore the comfort and confidence to eat, speak and smile that you once enjoyed when you had your own teeth.

Although naturally resilient, your teeth still face some significant dangers. Tooth decay and gum disease, “enemies” within the mouth, can severely damage your teeth and eventually lead to their loss.
But there are also external dangers just as devastating — traumatic injuries that can happen in the blink of an eye. Fortunately, we can treat even the most serious of these injuries and increase the chances of an injured tooth’s survival.
Here are some of those common dental injuries:
Chipped or Fractured Teeth. This is a case where a part of the tooth has been broken but it’s still firmly rooted in the mouth. If small portions of the enamel or dentin (the next underlying layer of the tooth) have been chipped, we may be able to reattach them or fill the affected tooth area with a natural-colored filling (larger broken portions may require a complete crown). If the damage has injured or exposed the inner pulp, a root canal treatment might be in order to prevent infection and reduce pain.
Dislocated (Luxated) Teeth. A dislocation occurs when the impact moves the tooth in an abnormal way in the socket. We must first reposition the tooth and, if need be, stabilize it by splinting it to neighboring teeth. This type of injury may also require a root canal treatment.
Knocked out (Avulsed) Teeth. It’s quite possible to replant a knocked out tooth — if you act quickly. Without touching the root, the tooth should be rinsed with cold, clean water and then placed into the empty socket within five minutes of the injury. If placement isn’t possible, the tooth should be placed in a container with milk or with some of the injured person’s collected saliva (to keep the root from drying out), and sent with the injured person to treatment. We need to see the injured person as soon as possible to make sure the tooth is repositioned properly and take other measures to protect it. We’ll also need to monitor it for proper healing for awhile.
Although some injuries may be too severe to save a traumatized tooth, seeking immediate treatment certainly increases the chances for survival. If you or a family member experiences such an injury, keep calm and contact us immediately.
