What does the term “two-implant overdentures” mean?
For more than a century, complete dentures were the only care option for edentulous (toothless) people. As a solution, these left a lot to be desired, particularly for the lower jaw. Now dental technology has developed a better alternative that combines two strategically placed dental implants and a traditional lower denture that has been modified to fit over the two implants — thus the term.
What are the problems with traditional dentures?
The problem is that when you lose teeth, the bone that supported the missing teeth begins to shrink away. This is known as resorption, and it is the reason that dentures fitted too soon after teeth are lost quickly become loose. Bone loss happens most rapidly during the first year and is four times greater in the lower jaw than in the upper.
Why not just use dental adhesives to hold dentures tightly to the lower jaw?
Zinc, a major ingredient in most dental adhesives, has been associated with neurological disorders and may be unsafe. In addition, dental adhesives are expensive and the cost of frequent usage adds up.
Besides dental adhesives, are other health problems associated with dentures?
Yes, edentulism has been related to poor nutrition. Many edentulous people switch to soft foods with high fat content because they find healthier foods like vegetables and proteins difficult to chew.
What are dental implants?
Dental implants are replacements for the roots of teeth, the parts that are below the gumline and anchored in bone. They are usually covered with a crown that shows above the line of the gums.
What are the benefits of implants?
Most importantly, implants reduce the amount of bone resorption. Studies have shown about 75% less resorption in parts of the jaw with implants compared to areas without them. Since most of the bone loss occurs within the first year after tooth loss, it is important to place implants within this time period.
Is a complete set of dental implants a good solution for edentulism?
Yes, it can be a good solution, but it is not for everyone. Some patients, who have lost a great deal of bone support, need another solution for cosmetic reasons that offer more facial support like an implant overdenture. In addition, depending on their resources and insurance, some people require a less expensive solution.
Why does the two-implant overdenture work better for the lower jaw?
Based on differences in bone volume, density and other factors, we think that four to six implants are needed to retain an upper implant overdenture. Thus a two-implant overdenture is a good solution to consider for a lower jaw, but other options might be preferred for an upper jaw.

A veneer is a cosmetic dental procedure that we use in some situations to correct discolored teeth, small spaces or gaps between teeth, small chips or oddly shaped teeth, and teeth that are slightly misaligned by placing a thin shell covering over the teeth. They are artistically hand-crafted by lab technicians out of tooth-colored porcelain using precise molds that we have made in our office. We attach veneers to the tooth's surface using a special adhesive that creates a chemical bond. Veneers are often a key component in a smile makeover.
Traditional veneers will require some tooth preparation, a process where we reduce or file down some of the facial (front, visible) portion of your tooth by 0.3 to 0.7 millimeters. For this reason this cosmetic procedure is not reversible.
How Long Do They Last?
Veneers can last from 7 to 20+ years depending on how you care for them. This may include sleeping in a protective, professionally made mouthguard. And while porcelain is a durable material that can withstand a great deal of pressure, you must remember that they are a type of glass. You could possibly shatter a veneer if you bite into anything that requires a hefty amount of twisting movement and biting pressure.
By using the latest technologies and procedures, we will create the naturally beautiful smile of your dreams and we will restore your mouth to full functionality and optimal health. Contact us today to discuss your questions or to schedule a consultation.

Tooth sensitivity is an issue that can range from a slight twinge at times to downright excruciating pain. However, before we continue, understanding the cause of tooth sensitivity is helpful to both relieving and treating it.
Tooth enamel is inert in that it has no nerve supply and thus it protects the teeth from temperature and pressure changes — the main cause of sensitivity. Once it is compromised, worn thin, or exposed due to gum recession, it leaves the delicate nerve fibers within the dentin vulnerable to touch, acid, and temperature change. These nerve fibers most often grab your attention when they come in contact with heat, cold, or a “double whammy” combination of both cold and sweet. They also become sensitive to touch — even the bristles of a soft toothbrush can irritate exposed dentin.
As for the causes of tooth sensitivity, one common cause we see is aggressive brushing. Yes, too much brushing can be bad for you! To be more specific, excessive, improper brushing with a sawing back and forth motion can erode the gum tissues, expose, wear, and even groove the dentin. Another cause for sensitivity can be from the destructive process of tooth decay that eats through the enamel and into the dentin.

When it comes to your oral healthcare, we strive to provide state-of-the-art care along with education to both our patients and community. One way we do this is by taking a moment to answer some of the questions we are most often asked about a certain topic. And one topic that almost always ignites questions is the subject of lumps and bumps in the mouth.
Help! I just found a small lump in my mouth — what should I do?
Not to alarm you, but your first priority is to contact us as soon as possible to schedule an appointment so that we can review it. Most often, we will know what it is by taking a history, knowing how long it's been there and what it looks like. Depending on what we find, we may want to take a biopsy so that we can determine exactly what it is and how we need to treat it.
What is involved in having a biopsy performed?
A biopsy is a normal and routine procedure that is used to definitively diagnose and confirm exactly what the abnormal lump, bump or other tissue is. It is typically performed with local anesthesia so that a small tissue sample can be removed without any pain for examination under a microscope. Depending on the size of the wound, it may require two to three sutures (stitches), leaving a flat and flush surface that heals in a few days to a week. The procedure usually lasts between 10 and 15 minutes with the lab results processed within a few days.
Does this mean I have cancer?
No, the chances are slim that you actually have cancer. However any change or sore in the mouth that does not heal in a week or two should be evaluated by a dentist and if necessary biopsied. If it is pre-cancerous and removed, it could save your life. The most important fact you need to remember is that no one can tell for sure what the abnormal tissue growth is until an expert in oral pathology (“patho” – disease; “ology” – study of) examines it under a microscope. While it is human nature to be concerned, until you have the facts, you are suffering needlessly.
