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’ve suddenly noticed one of your teeth looks and feels uneven, and it may even appear chipped. To make matters worse it’s right in front in the “smile zone” — when you smile, everyone else will notice it too. You want to have it repaired.
So, what will it be — a porcelain veneer or crown? Maybe neither: after examining it, your dentist may recommend another option you might even be able to undergo that very day — and walk out with a restored tooth.
This technique uses dental materials called composite resins. These are blends of materials that can mimic the color and texture of tooth structure while also possessing the necessary strength to endure forces generated by biting and chewing. A good part of that strength comes from the way we’re able to bond the material to both the tooth’s outer enamel and underlying dentin, which together make up the main body of tooth structure. In skilled, artistic hands composite resins can be used effectively in a number of situations to restore a tooth to normal appearance.
While veneers or crowns also produce excellent results in this regard, they require a fair amount of tooth alteration to accommodate them. Your dentist will also need an outside dental laboratory to fabricate them, a procedure that could take several weeks. In contrast, a composite resin restoration usually requires much less tooth preparation and can be performed in the dental office in just one visit.
Composite resins won’t work in every situation — the better approach could in fact be a veneer or crown. But for slight chips or other minor defects, composite resin could transform your tooth’s appearance dramatically.
To see if composite resin is a viable restoration option for your tooth, visit your dentist for a complete dental examination. It’s quite possible you’ll leave with a more attractive tooth and a more confident smile.
