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 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.

Like other healthcare providers, your dentist keeps records of your ongoing care. These include not only their written notes but also x-ray imaging, frequency of visits and cleanings, and any medical information that could affect your care. What’s more, they have a legal obligation to maintain these records.
Your dental records help guide decisions about your care. In that regard, you should consider something else—you may need to change providers: your dentist retires or you move; your dentist isn’t in your new insurance network; or, unfortunately, you have an “irreconcilable” difference with your provider.
If that happens, it’s very important your dental records find their way to your new provider. Here are 3 reasons why.
Your individual dental history. Each person’s dental situation and needs are unique. Your past records help clue in your new dentist about your past history and current needs, which will help guide how they treat you.
Time and money. Your dental records contain x-rays or other diagnostic information about your oral condition, including preparations for any upcoming dental work. If you change dentists before completing that treatment, your new dentist may have to start over with new diagnostic tests if they don’t have this previous data. It could cost you more money and make you wait longer for a needed procedure.
Coordinating dental care with your general health. Your mouth isn’t isolated from the rest of your body, and some dental treatment measures could affect other health conditions (and vice-versa). If your new dentist knows other health issues you may have from your previous records, it can help ensure you’re getting dental treatment appropriate to your overall health.
For the most streamlined transition between providers, it’s important your dental records follow you. You’re entitled to having those records transferred, and, if you’re uncomfortable asking yourself, your new provider can obtain them for you. Just be sure to ask.

You have a lot of options for replacing missing teeth, from state-of-the-art dental implants to affordable, but effective partial dentures. But if the teeth in question have been missing for a while, you may first have to undergo orthodontic treatment. Here's why.
While they may feel rigid and firm in the jawbone, teeth are actually held in place by periodontal (gum) ligaments. These elastic tissues lie between the teeth and the bone and attach to both with tiny filaments. This mechanism allows the teeth to incrementally move over time in response to biting pressures or other environmental factors.
When a tooth goes missing the teeth on either side of the space naturally move or "drift" into it to help close the gap. This natural occurrence can reduce the space for a restoration if it has gone on for some time. To make room for a new prosthetic (false) tooth, we may have to move the drifted teeth back to where they belong.
If you're thinking metal braces, that is an option—but not the only one. Clear aligners are another way to move teeth if the bite problem (malocclusion) isn't too severe. Aligners are a series of custom-made, clear, plastic trays worn over the teeth. The patient wears each tray, slightly smaller than the previous one in the series, for about two weeks before changing to the next one. The reduction in size gradually moves teeth to their intended target position.
Many adults prefer clear aligners because they're nearly invisible and don't stand out like metal braces. They're removable, so you can take them out for cleaning or for special occasions. And, we can also attach a prosthetic tooth to the tray that temporarily covers the missing tooth space.
Whichever orthodontic treatment you choose, once completed we can then proceed with restoration to permanently replace your missing teeth. While it can be a long process, the end result is a beautiful smile that could last for years to come.

What's your favorite winter sport? For some, it's all about swooshing down a snowy trail on skis, a board, or a sled. For others, the main attraction is skating at an ice rink or a frozen pond. If you're more of an indoors athlete, you may enjoy a fast-moving game of basketball or a round of squash. Or, you might take a turn on a climbing wall or a trampoline.
What do all these activities have in common? They're fun, they're great exercise…and they all come with a risk of injury to your teeth.
It's easy to see how a collision on snow or ice could result in a blow to the mouth. But did you know that basketball (along with hockey) is among the sports with the highest risk of facial injury? What's more, many "non-contact" sports actually have a similar risk.
Located front and center in the face, the incisors (front teeth) are the ones most likely to sustain injury. Unfortunately, they are also the most visible teeth in your smile. With all of the advances in modern dentistry, it's possible to restore or replace damaged teeth in almost any situation—but the cost can be high, both for present restoration and future preservation. Is there a better alternative?
Yes! It isn't sitting at home—it's wearing a custom-made mouthguard when there's a risk of facial injury.
Most people don't ski or play hockey without protective gear like a helmet. A mouthguard can effectively protect against dental injury that might otherwise be serious. Available here at the dental office, a custom mouthguard is made from an exact model of your own teeth, so it's comfortable to wear and fits perfectly—but no safety equipment can work if you don't use it!
So whether you like to hit the trails or the gym this winter, don't forget to bring a custom-made mouthguard. It's a small piece of gear that can save you from a big headache!
