When you first received your removable dentures the fit was firm and comfortable. Lately, though, they’ve become loose, making it difficult to eat or speak without slippage.
The problem may not be with your denture, but with bone loss. Human bone goes through a natural cycle of dissolving (known as resorption) and new growth to take the lost bone’s place. The jawbone receives further stimulation to grow from the forces generated by natural teeth when we bite or chew.
When natural teeth are missing, however, the jawbone lacks this stimulation, which over time results in bone loss and gum tissue shrinkage. Traditional dentures can’t transmit this stimulating force to the jawbone either, so the bone and gum structure under a denture will also shrink. This results in a looser fit for the denture.
The simplest option to correct a loose-fitting denture (especially if it’s the first occurrence) is to reline the dentures with additional material to re-form the fit to the new conditions in the mouth. A permanent relining will require sending your dentures to a dental laboratory to apply the new material based on a mold of your current anatomy beneath the denture.
If, however, your dentures have already undergone a few relinings, or after examining your gums we determine a relining won’t provide the fit and stability needed, then it may be time for a new denture. Although this is more costly than a relining, a new appliance could provide a more accurate fit to the current contours in your mouth.
The latter option may also give you a chance to benefit from advancements in denture technology or materials since you received your current denture. One such advancement is a removable denture that’s supported by implants. It’s possible to achieve this new supporting foundation for the denture with as few as two strategically-placed implants in the lower jaw.
If you’ve begun to notice denture looseness, be sure to make an appointment for an examination. From there, we can advise you on what will work best in your particular case.

A recent episode of “America’s Got Talent” featured an engaging 93-year-old strongman called The Mighty Atom Jr. The mature muscleman’s stunt: moving a full-sized car (laden with his octogenarian “kid brother,” his brother’s wife, plus Atom’s “lady friend”) using just his teeth. Grinning for host Howie Mandel, Atom proudly told the TV audience that his teeth were all his own; then he grasped a leather strap in his mouth, and successfully pulled the car from a standstill.
We’re pleased to see that the Atom has kept his natural teeth in good shape: He must have found time for brushing and flossing in between stunts. Needless to say, his “talent” isn’t one we’d recommend trying at home. But aside from pulling vehicles, teeth can also be chipped or fractured by more mundane (yet still risky) activities — playing sports, nibbling on pencils, or biting too hard on ice. What can you do if that happens to your teeth?
Fortunately, we have a number of ways to repair cracked or chipped teeth. One of the easiest and fastest is cosmetic bonding with tooth-colored resins. Bonding can be used to fill in small chips, cracks and discolorations in the teeth. The bonding material is a high-tech mixture of plastic and glass components that’s extremely lifelike, and can last for several years. Plus, it’s a procedure that can be done right in the office, with minimal preparation or discomfort. However, it may not be suitable for larger chips, and it isn’t the longest-lasting type of restoration.
When more of the tooth structure is missing, a crown (or cap) might be needed to restore the tooth’s appearance and function. This involves creating a replacement for the entire visible part of the tooth in a dental lab — or in some cases, right in the office. It typically involves making a model of the damaged tooth and its neighbors, then fabricating a replica, which will fit perfectly into the bite. Finally, the replacement crown is permanently cemented to the damaged tooth. A crown replacement can last for many years if the tooth’s roots are in good shape. But what if the roots have been dislodged?
In some cases it’s possible to re-implant a tooth that has been knocked out — especially if it has been carefully preserved, and receives immediate professional attention. But if a tooth can’t be saved (due to a deeply fractured root, for example) a dental implant offers today’s best option for tooth replacement. This procedure has a success rate of over 95 percent, and gives you a natural looking replacement tooth that can last for the rest of your life.
So what have we learned? If you take care of your teeth, like strongman Atom, they can last a long time — but if you need to move your car, go get the keys.
