It’s a common problem for denture wearers: after years of a comfortable fit, your dentures now seem to be uncomfortably loose. The reason, though, may have more to do with bone loss than the dentures.
Bone is a living tissue with a life cycle — it forms, it ages, and it eventually dies and dissolves (resorbs). It’s replaced with new bone and the cycle repeats. Additionally, the forces generated when we bite or chew are transmitted from the teeth to the jaw, which helps stimulate new bone growth. When the natural teeth are missing, however, the bone no longer receives this stimulus. Resorbed bone isn’t replaced at a healthy rate, which leads over time to bone loss.
Denture construction can also contribute to bone loss. The denture palate rests for support on the bony ridges that once held the teeth. Over time the compressive forces of the dentures apply damages and reduces the volume of gum tissue and eventually does the same to the bone. Combining all these factors, the reduced gum and bone volume will eventually alter the denture fit.
There are a few alternatives for correcting loose dentures. One is to reline them with new plastic, as either a temporary fix performed during an office visit or a more permanent relining that requires sending your dentures to a dental lab. Depending on the rate of bone loss, a patient could go through several denture relinings to accommodate ongoing changes in the jaw. At some point, though, it may be necessary to create a new set of dentures.
A third alternative that’s becoming increasingly useful is to incorporate dental implants into the denture design. Implants can of course be used to replace individual teeth, but a few strategically placed implants (usually of smaller dimension) can serve as a support platform for a removable denture. This relieves some of the compression force of a traditionally worn denture and can slow bone loss.

You expect a decayed tooth, a fracture or a gum infection to be the cause for that toothache causing you grief. Sometimes, though, the answer may be “none of the above”—there's nothing wrong going on in your mouth to cause the pain.
You pain is real—but its source is elsewhere in the body, a situation known as referred pain. It's important to find out the pain's true source to determine what kind of treatment you'll need to alleviate it.
Here are some of the likely candidates for a “toothache” that's not a toothache.
Facial nerves. Tooth pain may be associated with trigeminal neuralgia, a misfiring disorder of the trigeminal nerves that course through either side of the face. The nerve is divided into three branches, two of which are located in the upper face and one in the lower jaw. Because they're interconnected, a problem with one of the branches in other parts of the face could be felt in the branch around the jaw.
Jaw joints. Temporomandibular Joint Disorders (TMD) can cause pain in the pair of joints that connect the lower jaw to the skull. The joints can become inflamed due to stress or trauma and the associated muscles begin spasming, causing severe pain. Because of their proximity to the teeth, the pain from the joints can radiate into the dental area and mimic a toothache.
Ear or sinus infections. Both the ears and the maxillary sinus are subject to infections that can cause severe pain and pressure. With the close proximity of both the ears and the sinus to the upper jaw, it's quite possible for pain originating in these structures to be felt within the mouth.
These are only a few of the possibilities that also include migraines, shingles, fibromyalgia and even vitamin deficiencies. As such, your dentist or physician may need to do a little detective work to locate the true cause. But the effort to locate where your mouth pain is actually coming from will help ensure you get the right treatment to give you lasting relief.

As far as your appearance goes, the most important teeth you have are those in the “smile zone.” These are the teeth most visible when you smile—and the ones that awkwardly stand out if they're chipped, worn or otherwise flawed. More than any other teeth, they determine how inviting your smile is to others.
You might think you'll need extensive cosmetic dental work to fix these kinds of dental defects. But that may not be necessary: We may be able to use a dental material known as composite resin to repair the defects in your “smile zone” teeth in one office visit.
Composite resins are a combination of ceramics and plastics that have been around for some time. They've only recently come into wide use, though, with the development of new techniques to bond them to tooth surfaces. They're ideal for chips, cracks, or decayed areas where front teeth make contact with one another. They may also be used occasionally to reshape irregular or misaligned teeth.
You'll first need a complete dental examination to determine if composite resin bonding is an appropriate approach for your situation. If so, we'll begin by preparing the tooth surface to better accept the resin material. We'll then apply the liquid form of the material in layers, along with other agents to increase the material's strength. Each layer is cured (hardened) before applying the next layer.
As the layers build up, we shape the material to achieve a normal tooth appearance. We'll also incorporate your individual color shadings, so that the prepared tooth blends well with surrounding natural teeth. In effect, the procedure requires as much artistry as technical skill to create a natural look.
Though not as strong as porcelain veneers or crowns, composite resins are durable if not subjected to heavy biting forces. And for a few hours in the dentist's chair with minimal tooth preparation, a composite resin treatment can create a dramatic and exciting change in your appearance.
