After years of wearing a denture, many people realize the fit is not as dependable as when it was first made. It begins to slip while chewing and also rub sore spots on tender gum tissues.
The reason for this is due to bone loss. When natural tooth roots no longer exist in the upper or lower jaw, the bone begins to shrink, or ‘resorb.’ Resorption is also the reason a once-secure fitting denture feels less and less so after each year.
Most people are not aware that wearing a denture places pressure on the jaw bones, which speeds up the process of bone loss. For those who sleep in their dentures, the rate is accelerated even more.
Initially, after a denture is first made, patients may be advised to wear it 24/7 until becoming used to its presence in the mouth. However, after an adjustment period, you should remove it before bedtime. Studies have also shown that people who sleep in their denture have a higher risk for pneumonia.

For people who do everything possible to care for their dentures, however, there is no way to prevent bone resorption. In addition to the looser fit with each passing year, changes to facial appearance will begin to take place.
These changes include deep wrinkles that form around the mouth, having the corners of the mouth turn downward (even while smiling), a more pointed chin, having a mouth that seems collapsed into the face, and jowls that form as facial muscles detach from bone structures.
A temporary fix to loose dentures is a reline. This reshapes the gum base portion to fit the less prominent contours of a declining gum ‘ridge’ to which it was originally fitted. Yet, the problems will reappear as bone loss continues.
In the past, people who had experienced severe bone loss were required to first have a bone graft, often using a piece of hip bone to rebuild the jaw bone where implants were to be placed. As dental techniques advanced, bone rebuilding materials were developed that could regenerate bone mass, preventing the need for the more-involved surgical grafting procedure.
Fortunately, in 1998, a new dental implant system was introduced that enabled implant placement in even severely resorbed bone mass. All-On-4 dental implants relied on specially designed implants placed at unique angles. This technique evenly distributed the load among four implants.
There were additional advantages to the All On Four system. First, the procedure itself was less complex than traditional implant placement, making it possible for the patient to recover quickly. Too, teeth could be attached immediately after placement. So, not only could the patient walk out of the dentist’s office and meet a friend following the procedure, they could enjoy lunch together!
For many, the best advantage of all is in the lower cost as compared to many other implants systems. Because only 4 dental implants are needed to support a full upper or lower arch of teeth, treatment costs are typically quite lower than traditional implant types.
While All On 4 dental implants won’t work for every individual who is missing teeth, they are a beneficial option for a number of patients who wish to be rid of a bothersome denture. If you’re one, call 843-871-6351 to schedule a free, no obligation consultation.
