If an adult has lost his or her teeth (a condition called “edentulism”), full removable dentures (false teeth) can restore the person's appearance and ability to bite, chew, and talk properly. Even with our current extensive knowledge about tooth care and restoration, over 25 percent of Americans have lost all their teeth by the time they are 65.
How much do you know about dentures? Test yourself below.
How does tooth loss affect your bones?
Bone is a living substance that is constantly changing and rebuilding itself, depending on signals it receives from surrounding tissues. The bone that surrounds your teeth is called alveolar bone (from “alveolus,” meaning sac-like). To keep healthy, alveolar bone needs stimulation or function such as chewing and your teeth touching your opposing teeth. If you lose your teeth, bone begins to melt away (resorb).
How can we minimize bone loss during tooth extraction?
We can maintain bone volume by using bone grafting techniques. While this sounds scary, it is a relatively easy procedure. The principle of bone grafting is to build a sort of scaffolding on which your body begins to build and maintain its own bone. Bone loss can be prevented by the placement of a few dental implants.
How are dentures designed and created?
The dentures that look best and work best for you are based on your original teeth. We often utilize photographs of how you looked with your natural teeth, along with your input about possible changes you would like to see. First we take detailed impressions (molds) of the residual ridges in which your teeth once rested. From these we make denture bases of a light cured plastic resin. We attach horseshoe-shaped rims made of wax to the bases, to simulate the position of the teeth as we work out their design and spacing, based on both appearance and function. The prosthetic teeth are then tried out in your mouth, adjustments are made, and the dentures are processed in a dental laboratory. The final product substitutes a pink colored plastic (methyl methacrylate) to represent the gums and white plastic material as the teeth, created to make them look as natural as possible.
What is your part in the denture fitting process?
As a patient with new dentures, you must learn to use your jaw joints, ligaments, nerves, and muscles in new ways to help stabilize your dentures and to relearn to speak, bite, chew, smile, and laugh with these new structures. It takes a little practice, but with your removable dentures you can once again enjoy a complete and normal life.
What is composite resin bonding?
This term refers to a kind of tooth-colored material that is a mixture of a plastic resin and a glass filler. The glass gives the mixture, or composite, strength and translucency that is similar to a natural tooth. The composite is bonded to the tooth by slightly abrading or roughening the tooth so that the resin fills in small cuts in the tooth surface and bonds with it. The end result functions and looks like part of the original tooth.
What is bonding used for?
This technique is a good way to restore chipped or stained teeth or to change a tooth's shape or color. It can also be used to restore parts of a tooth near the gum line where the gums have receded and left the root partially exposed.
What are the advantages of bonding?
Composite resin tooth restorations have several advantages.
- They take only a single dental visit because they are done right in the dental chair rather than having to be sent to a dental lab for preparation.
- They are less expensive than many other dental restorations.
- They leave most of the original tooth intact since little tooth preparation or drilling has to be done in order to make the composite material bond to the tooth.
- They can be made in a wide range of colors and can be matched well with the teeth around them.
- Because little of the original tooth has to be removed, they are a good choice for teens, whose dental arches (upper and lower jaws) are still developing.
What are the disadvantages of bonding?
The composite resin material is not as strong as the original tooth material, so the bonded restorations may not last over a long time. If it does last, the material may also stain as it ages.
When should you choose bonding?
Composite resin bonding is a good choice for a quick and attractive tooth restoration that may be replaced later by something more permanent, such as porcelain veneers.
The goal of restorative dentistry is to return the teeth to full form (shape) and function. For years, a key tool for achieving this goal has been through the use of metal amalgams (silver looking dental fillings). However, this technique does have some disadvantages. One is the fact that they can involve removal of healthy tooth structure to retain them. Too much “undercutting” can undermine and weaken a tooth resulting in less resistance to biting forces possibly leading to fatigue fractures and cracked tooth syndrome. Another approach is call “biomimetic” which literally means mimicking life. This approach to dentistry is made possible through the structured use of tooth-like materials such as composite resins. Scientific studies and clinical experience have validated their use as both safe and predictable.
By mimicking life, we rely upon our delicate balance of artistry, experience and expertise to provide you with properly restored teeth that function and wear normally, while appearing indistinguishable from natural teeth. Dental composite are now the most commonly used materials for tooth-colored adhesive restorations and have properties similar to a natural tooth's enamel and dentin. They consist of resin which are plastic and fillers made of silica (a form of glass). The fillers give the composites wear resistance and translucency (see through properties). However, most of the properties of enamel are also mimicked quite well by dental porcelains. Porcelains are a form of ceramic, that are formed by the action of heat. Dental porcelains come in all colors and shades so we can easily and perfectly match the color of virtually any natural tooth. As for longevity, porcelain is typically your best option because it is the closest option in mimicking a natural tooth.

According to the Centers for Disease Control and Prevention (CDC), community water fluoridation has been a safe and healthy way to prevent tooth decay effectively for over 65 years now. In fact, the CDC has recognized water fluoridation as one of the 10 great public health achievements of the 20th century.
It all began back in the 1930's when it was discovered that fluoride had oral health benefits. However, community water fluoridation did not begin until January 25, 1945, when Grand Rapids, Michigan became the first city to add fluoride to its municipal water system. Before it was officially rolled out in other cities, Grand Rapids was compared to other cities or “controlled groups” that had not added fluoride to their water so that scientific research could assess the relationship between tooth decay and fluoride. Well, you can guess the results — it was proven that fluoride helped reduce tooth decay when added to ordinary tap water. On November 29, 1951, the National Academy of Sciences’ National Research Council (NRC) declared water fluoridation safe, effective, and beneficial based upon the results of their findings and the fact that there was a dramatic decline in tooth decay in the children of Grand Rapids.
Ever since, fluoride has continued to play a critical role as a simple, safe, effective way to provide improved oral health by helping reduce tooth decay in the United States. This reality is still being demonstrated with each new generation benefiting from better oral health than the previous generation.
As for identifying when the time is right to introduce fluoride to your children's oral health program, ask us. Most children get the right amount of fluoride to help prevent cavities if they drink water that contains fluoride. And if by chance you live in an area where your tap water is not fluoridated, brush your children's teeth with no more than a pea-sized amount of fluoride toothpaste twice a day and ask your dentist about fluoride supplements and treatment.

For generations, root canal treatment has received a bad rap. Thought to cause pain, it is actually just the reverse. The truth is that root canal treatment does not cause pain but actually relieves it. Not only does root canal treatment relieve pain, it literally saves the affected tooth or teeth from further damage and/or loss.
To get started, let's define this procedure. A root canal treatment is a procedure in which the diseased pulpal tissue in the root canals are removed, disinfected, cleaned, and sealed. This is usually necessary following inflammation and infection of the pulp — which is the cause of your pain — as a result of severe decay or in a very heavily filled or damaged tooth.
However, if left untreated, an infected tooth can spread into the bone and even cause an abscess — and that can be more painful and impact your overall general health. The good news is that once a tooth has had the appropriate endodontic treatment (“endo” – inside; “dont” – tooth) followed by a proper restoration, it can last as long as your other teeth. The key is to take proper care of your teeth, have routine cleanings, and visit our offices as soon as you feel you have a problem with a tooth.
If you are having pain from a tooth or several teeth, you may need a root canal treatment. Please contact us today to schedule an appointment before it gets worse. To learn more about the signs, symptoms, and treatment for a root canal, read the article “Common Concerns About Root Canal Treatment.”
