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.

Dental implants are a fascinating treatment option that can be life changing when used properly. They have also experienced tremendous scientific advancements and press over the years making them highly desirable by people of all walks of life.

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.

While the long-term success rate for a dental implant is well over 95%, there are factors that can compromise their success. For this reason, our office has put together this list so that you can be prepared should you ever need a dental implant. We feel that by providing our patients with this type of easy-to-understand information, we can educate, address any concerns and help produce the best results.
The three most common categories for classifying factors that influence dental implant success are: general health concerns, local factors and maintenance issues. As you may suspect, general health concerns include factors such as:
The second category is “local factors” and includes bone quantity and quality — there must be sufficient bone to anchor implants. Other considerations that fall into this category include whether or not you clench or grind your teeth or have additional bite concerns, as all of these can have negative impacts on both the short and long-term success of an implant.
The last category concerns maintenance. While dental implants are superior works of technology that can last a lifetime and produce results that are nearly identical to natural teeth in looks and durability, they do require routine maintenance. This includes daily cleaning (brushing and flossing) and routine visits to our office for evaluation and professional care to make sure they are functioning properly.

Dental implants are in much demand when it comes to replacing missing teeth. And although they have long-term success rates of well over 95% when properly placed, the dental profession's current rule-of-thumb is to not use them as a treatment option for teenagers because jaw and facial growth are not complete.
As with most things in life, timing can be everything. However, having missing teeth as a teen can contribute to significant loss of self-esteem and psychological issues. All this means is that we must review each patient's needs on a case-by-case basis so that we can determine the optimal time to place implants while maintaining your teen's self-esteem. However, the good news is that there are some temporary tooth replacements available until the timing is right for implants.
Unlike natural teeth, which move and change position along with normal growth and jaw development, implants don't. Because implants replace tooth roots by fusing with the jawbone, their position is fixed. If placed before normal jaw growth and maturity are complete, they appear to sink as the jaws grow and leave them behind!
Given the above details, you can clearly see why it is critical for jaw and facial growth to be complete prior to placing a dental implant. To determine this timeline, we will work with our dental team, which include orthodontists (specialist in the study of the growth, development and moving teeth into the right positions). Working together, we will best be able to assess when the time is right to plan and place dental implants — usually around late teens.
