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.

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.

Periodontal (gum) disease is a progressive bacterial infection caused primarily by bacterial plaque on tooth surfaces not adequately removed by daily oral hygiene. In fact, nearly all of us will develop gingivitis (inflammation of the gum tissues) if we fail to clean our teeth and gums for an extended period of time.
Some people, however, have a greater susceptibility for developing gum disease because of other risk factors not related to hygiene. Patients with diabetes are at particular high risk for acute forms of gum disease.
Diabetes is a chronic condition in which the body can’t adequately regulate the bloodstream’s levels of glucose, the body’s primary energy source. Type 1 diabetes is caused by inadequate production in the pancreas of the hormone insulin, the body’s primary glucose regulator. In Type 2 diabetes the body develops a resistance to insulin’s effects on glucose, even if the insulin production is adequate. Type 1 patients require daily insulin injections to survive, while most Type 2 patients manage their condition with medications, dietary improvements, exercise and often insulin supplements.
Diabetes has a number of serious consequences, including a higher risk of heart disease and stroke. Its connection with gum disease, though, is related to how the disease alters the body’s response to infection and trauma by increasing the occurrence of inflammation. While inflammation is a beneficial response of the body’s immune system to fight infection, prolonged inflammation destroys tissues. A similar process occurs with gum disease, as chronic inflammation leads to tissue damage and ultimately tooth loss.
Researchers have found that patients with diabetes and gum disease may lessen the effects of inflammation related to each condition by properly managing both. If you’ve been diagnosed with either type of diabetes, proper dental care is especially important for you to reduce your risk of gum disease. In addition to effective daily brushing and flossing and a professional cleaning and checkup every six months (more frequent is generally better), you should also monitor your gum health very closely, paying particular attention to any occurrence of bleeding, redness or swelling of the gums.
If you encounter any of these signs you should contact us as soon as possible for an examination. And be sure to inform any dental professional that cares for your teeth you’re diabetic — this could affect their treatment approach.
