Although dental implants are best known as single tooth replacements, they can actually play a role in multiple or complete tooth loss (edentulism) restorations. While replacing multiple teeth with individual implants is quite expensive, there’s another way to incorporate them in a restoration at much less cost — as supports for bridges.
In this case, only a few strategically placed implants are needed to support restorations of multiple crowns fused together into a single unit. Implant-based bridges consist of two main types: the first type is a fixed bridge, which is permanently attached to the implants and can’t be removed by the patient. It’s often the preferred treatment for patients who’ve lost most or all of their teeth but have not yet experienced significant bone loss in the jaw.
This choice, however, may not be the best option for patients with significant bone loss. In these cases, there’s a second type of fixed bridge: an implant-supported fixed denture. This type of fixed denture provides support for the lost bone support of the lips and cheeks. If a fixed bridge is not possible due to finances or inadequate bone support to place 4 to 6 implants, a removable denture (also known as an overdenture) that’s supported and held in place by implants is the next best alternative. Unlike a fixed bridge, an overdenture can be removed by the patient for cleaning purposes, and will require less investment than a fixed bridge.
For people with bone loss, the overdenture does more than restore chewing and speech function. Because bone loss can diminish support of the facial structures — actually shorten the distance between the chin and the tip of the nose — an overdenture provides additional bulk to support these structures to improve appearance. Depending on what the patient needs for facial support, overdentures for the upper jaw can be designed as “full palates,” meaning the denture plastic completely covers the upper jaw palate, or open in which the plastic doesn’t completely cover the palate.
Besides the condition of your teeth, gums and bone, your own personal preferences and financial ability will also play a role in which option is best for you. After considering all these factors, we can recommend which of these types of implant-based restorations will fit your needs. With either bridge, fixed or removable, you’ll certainly benefit from the improvement to both your mouth function and your smile.

Dental implants are by far the best way to replace missing teeth. But they do more than improve your smile: they can restore your ability to eat, chew and talk properly, especially if the teeth replaced are in the back of your mouth. What’s more, they can improve the entire look of your face by restoring facial height and cheek support lost because of the missing teeth.
There is, however, one obstacle to overcome before receiving dental implants — a lack of sufficient bone at the implant site. Bone loss usually occurs when teeth have been missing for some time. This is because when we chew the forces generated by the teeth stimulate continual bone growth to make up for older bone that has dissolved (resorbed). This stimulation doesn’t occur after teeth are lost, which slows the rate of bone growth. Over time the amount of healthy bone diminishes.
Without enough bone for support, implants can’t be placed properly. Fortunately, some of the bone can be regenerated through techniques that place bone grafting material at the site to stimulate and serve as a scaffold for new bone.Â The new bone will eventually replace the graft.
For missing upper back teeth with bone loss, we can take advantage of facial anatomy to grow the bone needed for implants. This area of the face is where the maxillary sinuses, air spaces lined with a tissue membrane, are located on either side just above the upper jaw. After determining their exact size and location through detailed x-ray imaging, we can surgically access the area inside the mouth just above the missing teeth.
The sinus cavity is an area where bone growth can occur by placing a bone graft between the floor of the sinus and the sinus membrane. Sometimes bone growth enhancers are used to stimulate and speed up regeneration. The procedure can usually be performed with local anesthesia (much like a routine tooth filling), with only mild discomfort afterward for a few days managed by an anti-inflammatory drug like ibuprofen and a decongestant for sinus swelling.
After six to seven months, we re-evaluate the area to see if sufficient bone has returned for implant surgery. If so, you will be well on your way to achieving a new look and better function through dental implants.

Which would you rather have — the flu or a root canal procedure? Nearly 80 percent of people recently surveyed by the American Association of Endodontists wisely chose the root canal. If this takes you by surprise, then let us bring you up to date on root canal treatment today. It’s nothing like the experience that once made it the butt of jokes and a benchmark against which other “undesirable” experiences were measured.
The term “root canal” actually has two meanings. It is part of the pulp-filled chamber at the center of every tooth containing nerves and blood vessels that keeps teeth vital (alive). It’s also the endodontic (endoÂ = inside; dont = tooth) procedure that treats inflammation and infection in this tissue. Common causes of pulp problems are traumatic damage (for example a crack, chip, or root fracture), deep decay, or gum disease.
The first sign of a problem is typically pain — ranging from acute and intense pangs when biting down, to lingering discomfort after consuming hot or cold foods, to a chronic dull ache and pressure, or tenderness and swelling in nearby gums. The primary pain may abate as the nerves in the pulp die, but the infection will continue, compromising the affected tooth, jeopardizing the health of the surrounding tissues, and often triggering secondary pain.
Pain-Relieving, Tooth-Saving Treatment
Endodontic treatment, by contrast, is no more uncomfortable than having a cavity filled. The tooth and surrounding area are numbed with a local anesthetic before the procedure begins. In order to access the diseased pulp, a small opening is made in the biting surface of the tooth. Tiny instruments are used to remove the pulp, clean and disinfect the root canal(s) and pulp chamber, and prepare the empty tooth interior to receive a biocompatible filling material to prevent bacteria from returning. A permanent crown may be placed over the tooth at that time, or a second visit may be needed. A crown (cap) is important to the tooth's long-term strength and functionality.
For a day or two following treatment you may experience temporary sensitivity, which often responds to an over-the-counter medication like ibuprofen. Occasionally, prescription medications, including antibiotics, may be needed.
All in all, doesn’t saving a tooth sound easier and more constructive than coming down with the flu?

The market for sugar alternatives has grown exponentially since saccharin was accidentally discovered in 1878. Today, saccharin has been joined by other FDA-approved zero-calorie artificial sweeteners, including aspartame (“Equal®” or “NutraSweet®”), sucralose (“Splenda®”) and rebaudioside A, derived from the stevia plant. You can also choose low-calorie alcohol sugars like erythritol or xylitol.
With rare exceptions, all these choices are widely considered safe substitutes for table sugar, high fructose corn syrup or other versions of this plentiful carbohydrate. Finding substitutes for sugar is a worthy health goal: besides its role in obesity, sugar is considered a contributing factor in cardiovascular disease and diabetes.
It's also a prime food for oral bacteria that cause dental disease. As bacteria consume sugar they produce acid as a byproduct. Acid softens and dissolves the mineral content in enamel, leading to erosion and the formation of cavities. While saliva normally neutralizes acid after we eat, constant snacking and higher quantities of sugar in our food make it difficult for it to control or neutralize acid in the oral environment.
Because most of us are hard-wired with a “sweet tooth,” it's difficult for many to cut back on sugar. Artificial sweeteners help reduce the amount of sugar in the diet with obvious benefits for general health. It can also make a big difference in your dental health by helping you prevent tooth decay.
One alcohol sugar may even go a step further. In addition to reducing the presence of sugar in the mouth, xylitol (found in chewing gums, candy and breath mints) also seems to reduce bacterial growth by interfering with their ability to ferment the sugar.
If you're considering using an artificial sweetener, get to know them first: some like aspartame aren't suitable for baked goods or cooking, while saccharine or sucralose are. People with a rare genetic condition called phenylketonuria also can't properly process aspartame in the body.
Be sure you also talk to us about artificial sweeteners' impact on oral health, especially the benefits of xylitol for dental care. Used in a wise and informed way, these sugar alternatives can improve both your oral and general health.
If you would like more information on artificial sweeteners impact on dental health, please contact us or schedule an appointment for a consultation.

Acquired Immune Deficiency Syndrome (AIDS) jolted our collective consciousness in the 1980s. The deadly disease caused by the human immunodeficiency virus (HIV) had no known cure and, at the time, no effective treatment.
HIV is a retrovirus, a virus with a genetic makeup and reproduction system differing from other kinds. After taking up permanent residency in the body, HIV begins “hijacking” the replication process of cells in the body's immune system and replacing it with a copy of its own. This destroys the cells' ability to protect the body from hostile organisms. As the virus affects more and more cells, the patient's condition ultimately develops into AIDS.
An estimated 35 million people worldwide (1.2 million in the U.S.) are currently infected with the virus. Thanks to new antiretroviral drugs, though, HIV can be kept from accelerating into AIDS. While their condition remains serious, many HIV positive patients can now live long and relatively normal lives. Even so, having the virus requires them to pay close attention to their health, including their mouth.
Even while stalled from becoming AIDS, HIV can still cause oral problems for 30 to 80% of patients. The fungal infection candidiasis (also known as thrush) is the most common of these problems, which appears as lesions, cracking skin or creamy white patches on the tongue or palate that easily bleed. Patients also have higher risks for dry mouth, oral cancer and periodontal (gum) disease.
HIV positive patients must practice diligent daily oral care and see their dentist for checkups regularly. Prevention, early diagnosis and treatment can keep gum disease and other damaging conditions under control. Monitoring oral health is also important because certain mouth conditions could be an early sign the infection is entering a new advanced stage in the body that requires additional attention.
Keeping vigilant in all aspects of health is a way of life for someone with HIV. Such vigilance, though, can help them maintain a healthy mouth and even prolong their life.
