Before determining if a bridge or an implant will work best for you, here is some useful background information. There are two main parts to a tooth; the crown or part that you see above the gum line and the root portion that is below the gum line and encased in bone — the part that is replaced by a dental implant.
A dental implant is inserted into the jawbone during a surgical procedure. The implant is actually a titanium screw-like device that is placed in contact with the bone. During a 3 to 6 month healing period, it subsequently fuses to the bone. A crown made from dental porcelain, gold or a combination of both is then attached to the implant to mimic a healthy, normal tooth.
There are two critical reasons why implants are the preferred method for permanently replacing an adult tooth. The first is that they are less susceptible to gum disease and they are not subject to tooth decay. The second is that because they attach to the jawbone and not to the adjacent teeth. And while an implant may cost a little more initially, when compared to the longevity and replacement cost of bridgework over a lifetime, they may cost less.
By contrast, a fixed bridge is also a non-removable restoration or prosthesis (replacement part) that is held in place by attaching it to your natural adjacent teeth. The treatment gets its name from the French word for bridge, “pont,” as the tooth being replaced is called a pontic. Before placing a bridge, the teeth on either side of the missing tooth must be prepared by removing layers of tooth enamel. Three new teeth are then crafted as a single unit from dental porcelain and/or precious metals with crowns on either side of the pontic. The pontic is held in place when the crowns are placed. Bridgework is at risk for gum disease and tooth decay and requires careful maintenance.
As with most dental procedures you have options and choices. Luckily, when it comes to determining whether a bridge or an implant will work best for you, you can rely upon our expertise. However, by having a clear understanding of these two options you are now better prepared for working with us should you require this treatment option. To learn more read the article, “Implants Vs. Bridgework.” Or, contact us to discuss your questions or to schedule an appointment.
When a device meant to make your life easier doesn't function properly, it can be extremely frustrating. This is sometimes the case for people who wear lower dentures, which loosen over time. These removable replacement teeth can become less reliable and more uncomfortable. Why does this happen?
The answer is bone loss. When a tooth is lost, the bone surrounding it deteriorates and this will change the shape of the jawbone in your mouth. You may find that a lower denture that once had a snug fit on your lower jaw is now sliding around. This happens more often on the bottom because your muscular tongue pushes against the denture. Also, a top denture has more surface area due to an artificial palate to help create suction to the roof of the mouth and keep it in place.
Dental implants, which permanently replace the roots of teeth, do not loosen and they also prevent bone loss. But replacing a whole set of bottom teeth with dental implants and crowns is expensive. What to do?
There's a relatively new solution that combines the security of implants with the affordability of a removable denture. It's called an overdenture, and it may be something you want to consider. An overdenture is a lot like the removable lower denture you already have, only it fits over two implants strategically placed in your lower jaw. While the lower denture is still removable, its stability is greatly improved.
Studies have shown that people with two-implant overdentures have a higher quality of life, and receive better nutrition, than those wearing conventional dentures. It's not hard to figure out why: A more stable denture makes it easier to eat healthy foods such as vegetables — or, really, any foods — and prevents embarrassing slippage of false teeth.

While the first recorded attempts at dental implant were recorded around 600 AD during the Mayan civilization, today they have become a normal and integral tool that we use to replace teeth and restore full functionality to dental and oral health. In fact, many dentists now refer to dental implants as a person's third set of teeth, and they are the optimal choice for permanently replacing missing adult (permanent) teeth.
To help you visualize, think of your teeth as having two main parts: the crown or the part that can be seen above the gum tissues and the root, the portion that is suspended in the bone by the periodontal (gum) ligament that keeps the tooth in place. A dental implant is actually a root replacement, but unlike a tooth's root, it is anchored in the jawbone. However, an interesting fact is that the dental implants being used today actually fuse with or integrate in to the bone to become one. This process is called “osseo-integration.”
For the most part, dental implants are made from commercial-grade, pure titanium. This metal is “osteo-philic” or literally a bone loving metal that has been used for many years by both the medical and dental professions because it is not rejected by the body. For these reasons, these dental implants are very successful and can last for a lifetime.
Implant placement is a surgical process that requires prior planning involving collaborative efforts between the implant surgeon, dentist, and a laboratory technician. Periodontists, oral surgeons, or general dentists with advanced training in implantology and surgery normally “place” them.

Modern dental implants not only help you maintain your normal chewing ability and speech patterns after you have lost a tooth or teeth — they also keep you looking younger. How do they do this? Read on.
Do lost teeth cause tooth-supporting bone to “melt” away? Yes. Of course, the bone does not actually melt. Bone is a living tissue, and under normal conditions it constantly dissolves and rebuilds. Stimulation by the small stresses from the contact of upper and lower teeth — something that normally happens hundreds of times each day — keeps these two forces in balance. When a tooth is missing, the bone that normally surrounds and supports the tooth (called alveolar bone) no longer receives the stimulation that causes it to rebuild, and it begins to diminish over time.
What happens if you don't replace missing teeth? The first year after a tooth is lost, the width of the bone that once surrounded the tooth decreases by 25 percent. Over the years, gradually increasing bone loss results in sunken cheeks and lips, making you look older. Gum tissue also decreases, affecting your ability to chew and speak.
What happens if you lose all your teeth? For people who have lost all their teeth, called edentulous, the effects are severe. After the alveolar bone is lost, the bone beneath it, called basal bone, also begins to be resorbed, eventually causing the lower part of the face to partially collapse.
Do partial or full dentures prevent bone loss? Unfortunately, just the contrary is true. A removable denture pressing on a person's gum increases bone loss because the pressures from biting are not transferred into the internal structure of the bone but instead are compressive, which damages the bone over time. This is why dentures begin to fit poorly after they have been worn for a while. This problem can be reduced by anchoring dentures with strategically placed dental implants.
What is a dental implant? A dental implant is a tooth-root replacement that is made of titanium. This metal is able to osseointegrate, or fuse with the bone. For a single tooth replacement, a crown that looks and functions like natural tooth is attached to the titanium implant. As mentioned above, implants can also be used to anchor dentures.
Does an implant prevent bone loss? Yes. When dental implants fuse to the jaw bone, they stabilize the bone. They also provide tooth-to-tooth stimulation that was formerly supplied by the natural tooth.
How long do dental implants last? Dental implants have been shown to last at least 10 years. For most people, implants will last the rest of their lives.

Dentists often recommend bone grafting to ensure the success of dental implants. And it is likewise common for people to squirm a bit at the thought. Bone graft? That sounds serious. And maybe a bit, well, unappealing. These feelings are completely understandable. After all, this may be something you've never had to consider before. But there's no reason to worry. HereÃ¢Â€Â™s why:
- Bone grafting is not new or experimental. It is actually a very routine part of the implant process, as well as other types of oral and periodontal surgery. And it is very successful when performed by an experienced doctor.
- Bone grafting materials are processed for safety. The grafts used — whether synthetic or from a natural source, such as cow or human bone — have been specially treated for medical use.
- Only a small amount of this bone-grafting material is needed. Once placed in the site of the missing tooth, it serves as a helpful scaffold your body uses to build more of its own bone in that spot.
- Your implant will be more ideally positioned and may work better. It needs a good, strong foundation with which to fuse. But when teeth are lost, this supporting bone is often lost, too. This loss is often unpredictable and bone grafting limits the change that occurs. In fact that's one of the main benefits of replacing missing teeth with implants: they help prevent bone loss just as a natural tooth does.
- Your implant will look so much better! Think about it: Your original tooth was supported to a certain height by the underlying bone. If that bone is now gone, the replacement tooth is going to be much longer because of the missing bone height. It may not look quite right without that additional support.
So if you want the best-looking and best-functioning implant possible, have no fear of bone grafting. And please contact us to discuss any of your concerns, or schedule an appointment for an implant consultation.
