Some patients who wear dentures face a kind of Catch-22: their denture fit may have loosened and become uncomfortable over time due to continued bone loss, yet the same bone loss prevents them from obtaining dental implants, a superior tooth replacement system to dentures.
But there may be a solution to this dilemma that combines the stability of implants with a removable denture. A set of smaller diameter implants — “mini-implants” — can support a removable denture with less bone than required by a conventional implant.
Like all living tissue, bone has a life cycle: after a period of growth, the older bone dissolves and is absorbed by the body, a process known as resorption. The forces generated when we bite or chew are transmitted by the teeth to the jawbones, which stimulates new bone formation to replace the resorbed bone. When the teeth are lost, however, the stimulation is lost too; without it, resorption will eventually outpace bone growth and repair, causing the bone mass to shrink.
Removable dentures also can’t supply the missing stimulation — bone loss continues as if the dentures weren’t there; and due to the compressive forces of a denture, bone loss accelerates. As the jawbone structure used to originally form the denture’s fit eventually shrinks, the denture becomes loose and difficult to wear. It’s possible to adjust to the new jaw contours by relining the dentures with new material or creating a new set of dentures that match the current bone mass. Without adequate bone, fixed crowns or bridges anchored by conventional implants may also be out of the picture.
On the other hand, mini-implants with their smaller diameter need less bone than the traditional implant. A few strategically placed within the jaw are strong and stable enough to support a removable denture. One other advantage: these mini-implants can be installed in one visit with local anesthesia and usually without the need for incisions or stitches.

Fans of the primetime TV show The Middle were delighted to see that high school senior Sue, played by Eden Sher, finally got her braces off at the start of Season 6. But since this popular sitcom wouldn’t be complete without some slapstick comedy, this happy event is not without its trials and tribulations: The episode ends with Sue’s whole family diving into a dumpster in search of the teen’s lost retainer. Sue finds it in the garbage and immediately pops it in her mouth. But wait — it doesn’t fit, it’s not even hers!
If you think this scenario is far-fetched, guess again. OK, maybe the part about Sue not washing the retainer upon reclaiming it was just a gag (literally and figuratively), but lost retainers are all too common. Unfortunately, they’re also expensive to replace — so they need to be handled with care. What’s the best way to do that? Retainers should be brushed daily with a soft toothbrush and liquid soap (dish soap works well), and then placed immediately back in your mouth or into the case that came with the retainer. When you are eating a meal at a restaurant, do not wrap your retainer in a napkin and leave it on the table — this is a great way to lose it! Instead, take the case with you, and keep the retainer in it while you’re eating. When you get home, brush your teeth and then put the retainer back in your mouth.
If you do lose your retainer though, let us know right away. Retention is the last step of your orthodontic treatment, and it’s extremely important. You’ve worked hard to get a beautiful smile, and no one wants to see that effort wasted. Yet if you neglect to wear your retainer as instructed, your teeth are likely to shift out of position. Why does this happen?
As you’ve seen firsthand, teeth aren’t rigidly fixed in the jaw — they can be moved in response to light and continuous force. That’s what orthodontic appliances do: apply the right amount of force in a carefully controlled manner. But there are other forces at work on your teeth that can move them in less predictable ways. For example, normal biting and chewing can, over time, cause your teeth to shift position. To get teeth to stay where they’ve been moved orthodontically, new bone needs to form around them and anchor them where they are. That will happen over time, but only if they are held in place with a retainer. That’s why it is so important to wear yours as directed — and notify us immediately if it gets lost.
And if ever you do have to dig your retainer out of a dumpster… be sure to wash it before putting in in your mouth!

Periodontal (gum) disease is an infectious condition that if left untreated could lead to tooth loss. While gum disease is primarily caused by a thin layer of bacterial plaque and calculus left on the teeth due to poor hygiene, you may also have extenuating factors that may make you more susceptible to the disease.
Gum disease is actually a group of infectious diseases in which some forms are more difficult to control than others. All these forms arise from interactions between the bacteria in the dental plaque and your body’s immune system. Depending on both your body’s individual response and the disease form, your resistance to the resulting bacterial infection may be low.
That low resistance to certain strains of bacteria may be genetic — something you’ve inherited from your parents. Your stress level, particularly when it’s high, can also diminish your body’s ability to resist disease. There are also numerous strains of bacteria that could lead to gum disease — your body may not be able to effectively resist the particular “mix” of strains contained in your dental plaque.
Aside from lifestyle issues like stress or oral hygiene, we can at least test and verify any susceptibility you may have due to uncontrollable factors like genetics or the particular bacterial makeup within your plaque. Unfortunately, a minority of people will continue to deal with gum disease even after treatment and adopting a more effective hygiene regimen. Although we can’t cure the disease, we can certainly control it with regular monitoring and treatment when necessary.
The key is to adopt a long-term strategy that will seek to preserve the teeth for as long as possible. In some cases, the best treatment approach is to prolong the life of the affected teeth for as long as possible to give you time to prepare emotionally and financially for eventual tooth replacement.
Indeed, any patient experiencing some form of gum disease should seek professional treatment, followed by a daily oral hygiene program and regular checkups and office cleanings. Taking the right steps in consultation with your dentist will assure you’ll preserve your teeth for as long as possible.
