The image of Grandma and Grandpa taking out their dentures every night and placing them in a glass of water by the bed is still a reality for a lot of people.
If you have dentures, you probably know that the conditions in your mouth will or have changed over time, necessitating adjustments. This is because full dentures exert continuous pressure on the gum tissues and underlying bone of your jaw resulting in a slow shrinkage. The gum tissues, and the bone beneath, atrophy or melt away. The result — over time the dentures lose their original tight fit and become loose. This can cause discomfort and embarrassment as the dentures slip and slide around.
Reline (refit) your current dentures. If your dentures are in good condition and are functional, applying a new inner lining to the dentures will restore their former fit. Because the rate of bone loss differs from person to person, some denture wearers may need more frequent relines than others. A temporary reline involves adding a layer of moldable plastic material under the denture while you are in the dentist's chair. The material will harden and fill in spaces where the gums have shrunk away from the denture. For a more permanent relining, the dentures must be sent to a dental lab, which will replace the temporary material with permanent denture material. This can usually be done in one day.
A new set of dentures. If your dentures are worn or you cannot speak, eat, bite or chew properly with them, a new set of dentures may be the answer. The condition of your jaw is another factor. If examination shows that a reline will not achieve the fit and stability you need, then remaking the dentures is another option.
Dental Implants — State-of-the-art tooth replacement systems. Dentures used to be the only solution to the problem of missing teeth, but with today's technology it's amazing what dentists can do. Implants do not only replace teeth but also stabilize the gradual bone loss that takes place when teeth are missing. Choose dental implants to replace at least two of your missing teeth to anchor your dentures and make them more stable.
Have all your missing teeth replaced with dental implants. Dental implants are generally the best option for long-term denture wearers who have endured jawbone loss and can no longer tolerate dentures alone. Bridgework (or dentures) are attached to the implants, stabilizing them and the underlying bone. The new teeth also provide support to the face, lips and cheeks giving a more youthful appearance.

Why is it important to replace missing teeth with restorations such as dental implants? You might be surprised to find that the damage caused by missing teeth is much greater than the simple gaps left in your smile.
As the years go by, teeth lost early in adulthood cause structural changes in a person's face. By age 45 changes in facial structure are already visible in the form of sunken cheeks. By 60, cheeks and lips lose their support, resulting in an aging look. This process continues and if the teeth are not replaced, much of the structural support of the person's face is lost.
These changes are caused by loss of bone. Although it may seem static, bone is actually living tissue that needs constant stimulation to maintain its form and density. With normal stimulation it is in a constant state of resorption (breaking down) and deposition (building up). Teeth provide the needed stimulation for the bone that surrounds them (called alveolar bone) as they meet each other during biting, chewing, and speech. When the stimulation continues, the bone continues to rebuild itself. Without this stimulation, the bone resorbs, does not build up again, and loses substance.
Without stimulation, alveolar bone loses width, height, and volume. Since your teeth and their surrounding bone support your chin, cheeks, and lips, this has a powerful effect on your appearance. It may also affect your ability to chew and to speak.
As alveolar bone diminishes, the next layer of bone also begins to resorb. This is the bone of the jaw itself. The lower part of the face begins to collapse, and the cheeks become hollow. This effect is especially noticeable for people with no teeth (edentulous).
Usually the first tooth to be lost, due to infection and decay, is a molar (back tooth). In the past, a missing single back tooth was frequently replaced by a fixed partial denture (FPD). A crown is provided for each of the two teeth on the sides of the gap, called abutment teeth, to support a false tooth in the middle. However, if they are not well cared for, the abutment teeth may be the next to succumb to decay.
Today the treatment of choice is an implant. A dental implant is a tooth-root replacement made of titanium, which fuses with the bone — making it very stable. Above the gums it is covered by a crown that looks like a natural tooth. The benefit of the implant is that it continues to provide stimulation to the alveolar bone, preventing bone loss.
Implants are also a good choice in the case of multiple missing teeth. They can be used to support bridges or false teeth (dentures). The results are an improved, younger appearance and better functionality.

When it comes to replacing missing teeth, we have numerous options. However, two of the most common treatment options include bridgework and dental implants. See how much you really know about dental implants and bridgework by taking our quick and easy true/false self test.
- When it comes to costs, dental implants may initially cost more than bridgework but are less expensive than bridgework over a lifetime.
True or False
- Both bridgework and dental implants can last a lifetime when properly maintained.
True or False
- Prior to placing a three-unit fixed bridge, if the surrounding teeth have crowns, they must be redone so that the bridge fits and wears properly.
True or False
- Replacing a single tooth with a three-unit bridge, requires removing the enamel on the adjacent teeth even if these teeth are disease-free.
True or False
- In addition to being permanent tooth replacements, another advantage of dental implants is that they don't decay like teeth supporting bridgework.
True or False
- It is not uncommon for root canal treatment to be required to save teeth that support bridgework if they have been subjected to severe decay and their nerves become infected.
True or False
- Placing a dental implant requires more time when compared to placing a three-unit bridge.
True or False
- Both bridgework and dental implants require minor surgery to replace a missing tooth.
True or False
- Dental implants are more desirable than bridgework because placing them does not affect the adjacent teeth.
True or False
- Studies indicate that bridges are only 67% successful at 15 years whereas dental implants have success rates into the 90s.
True or False
Answers: 1) True. This fact shocks many people. 2) False. This is more commonly true for dental implants. 3) True. 4) True. This is one of the disadvantages of bridgework. 5) True. This is just one of the advantages of a dental implant. 6) True. 7) True. 8) False. Dental implants require surgery to be placed. 9) True. This fact is a significant advantage for dental implants. 10) True. Your results may vary; however, this statistic represents what you might expect.
Most people think of bone as rock-solid, but it's actually a living tissue that's constantly changing. This has significant implications for your oral health, general health, and appearance — if you are one of the 70% of Americans missing at least one tooth.
Throughout the day, your top and bottom teeth make hundreds of fleeting contacts with each other. These small stresses are transmitted though the periodontal ligament (“peri” – around; “odont” – tooth) that supports each tooth in its socket like a hammock. Think of it as a gentle push on the hammock, which causes the tooth to gently bump the underlying bone. The bone then builds up in the spot that's receiving stress to counteract it. This constant remodeling of bone is what allows bone to stay healthy and strong.
When a tooth is lost, the bone does not receive that gentle stress. It reacts by literally melting away. Sometimes this happens fairly quickly — in a matter of months. After the tooth-supporting bone is lost, the jawbone itself begins the same process of deterioration. This could eventually change the shape of the face, as the distance from nose to chin can decrease — even if only a few back teeth are missing. The results aren't pretty. But the good news is, there's a way to prevent all this.
Dental implants, which function as substitute tooth roots, actually save underlying bone when teeth are lost. They do this because they are made of titanium, which fuses to the bone in which it's set, stabilizing it. The implant is topped by a realistic-looking crown, which replaces the part of the missing tooth that was visible in the mouth. Together, they look and function just as your natural tooth did.
If you are missing a lot of teeth, implants can also be used to anchor bridges or even removable dentures while providing that same bone-saving benefit. And when you consider that they are so durable they should never need replacement, implants are a great investment.

The best method for permanently replacing a missing tooth is with a dental implant. But did you know that there are two main techniques for placing implants? Implants can be placed either using a one stage or a two stage surgical technique, and as their names suggests, one is performed in one step while the other requires a second surgery.
With a one-stage procedure, a healing abutment is placed at the time of surgery. An abutment is a connector that attaches the implant from the bone into the mouth and which protrudes through the gum tissues. Following a 3 to 6 month healing period in which the implant fuses to the bone, a crown is then placed on the implant restoring the immediate appearance of a healthy, normal tooth. One-stage implant systems are generally used when the bone quality is good, guaranteeing good initial implant stability. They are also used when cosmetics is not a concern, such as the back areas of the mouth.
Under special conditions an implant can be placed and a crown placed on top of it at the same time. However, this is a very special circumstance requiring ideal conditions and surgical experience as well as crown fabrication know-how. It is generally safer and wiser not to subject an implant to biting forces until it is fully healed and integrated with the supporting bone.
A two-stage procedure is typically used for replacing teeth where there is no immediate need for a cosmetic solution and when more of a margin of safety is required. With this approach, the implant(s) are placed into the jawbone and the gum tissues cover them. They are not exposed to the mouth, but stay buried and left to heal. Once healed, a second surgery is performed to attach an abutment for securing the crown in place. This approach is used when there is poorer bone quality or quantity. This may make it necessary to regenerate bone around the implant at the time of its placement. There may also be other health considerations dictating that a two-stage approach may be indicated.
Depending on your individual situation and medical status, our implant team will determine which approach is best for you.
