If you’ve lost some teeth you may eventually want to replace them with dental implants. Implants by far are the restoration of choice due to their life-likeness and durability. But those advantages don’t come cheaply — implants can be expensive especially for multiple teeth.
If you’re forced to wait financially for implants, you still have other intermediary options like a removable partial denture (RPD). The conventional RPD has a rigid acrylic base colored to resemble gum tissue supported by a metal frame with attached prosthetic (false) teeth at the missing teeth locations. They’re held secure in the mouth through metal clasps that fit over the remaining teeth.
But these conventional RPDs can sometimes be uncomfortable to wear and don’t always cover the bottom of the gum completely. If this is a concern, you might consider an alternative: flexible RPDs. The base of this RPD is made of a form of flexible nylon rather than acrylic plastic. They’re much more lightweight but still fit securely in the mouth with thin plastic extensions rather than metal clasps. The base can also be more easily formed to cover areas where gum tissue may have receded.
While flexible RPDs hold up better to wear and tear than their conventional counterparts, they must still be maintained like any other appliance. They can accumulate plaque (bacterial biofilm) responsible for tooth decay and periodontal (gum) disease, so daily thorough cleaning is a must. And if there fit becomes loose they can be more difficult to reline or repair than other types of dentures.
They also share a common weakness with other dentures — they can’t prevent and may even stimulate bone loss. As bone ages, old cells dissolve and new ones form to take their place. As we eat and chew our teeth transmit the forces generated through the teeth to the bone to stimulate it to grow. RPDs and other dentures can’t transmit this stimulus, so the bone replaces much slower to the point that the bone volume can diminish.
That’s why it’s best to consider any RPD as a temporary solution until you can obtain an implant for a more permanent and bone-friendly option. In the meantime, though, an RPD can provide you with a great solution for both form and function for missing teeth.

Office cleanings and other minor procedures are a routine part of regular dental care. For some people, though, a routine visit could put them at slight risk for a serious illness.
The reason for this concern is a condition known as bacteremia. This occurs when bacteria, in this case from the mouth and conceivably during an office cleaning or other routine dental procedure, enters the bloodstream. Although for most people this isn’t a great issue, there’s been concern that bacteremia could further compromise the health of patients with or susceptible to other conditions like endocarditis (heart inflammation), prosthetic joints or compromised immune systems.
This concern grew out of a number of studies in the early 20th Century that seemed to show a link between dental bacteremia and infective endocarditis. At about mid-century it became a common practice to administer antibiotics before dental work (usually 2 grams of amoxicillin or an equivalent about an hour before) to high risk patients as a way of protecting them against infection. The practice later expanded to other health issues, including many heart conditions.
Beginning in 2007, however, guidelines developed jointly by the American Heart Association and the American Dental Association reduced the number of conditions recommended for antibiotic therapy. Based on these guidelines, we now recommend pre-procedure antibiotics if you have a history of infective endocarditis, artificial heart valves, certain repaired congenital heart defects, or heart transplant that develops a subsequent heart valve problem. Patients with prosthetic joints or immune system problems are no longer under the guidelines, but may still undergo antibiotic therapy if believed necessary by their individual physician.
If you have a condition that could qualify for antibiotic therapy, please be sure to discuss it with both your dentist and physician. We’ll work together to ensure any dental work you undergo won’t have an adverse effect on the rest of your health.

A loose primary (“baby”) tooth is often a cause for celebration. A loose permanent tooth, however, is a cause for concern. A permanent tooth shouldn't even wiggle.
If you have a loose tooth, it's likely you have a deeper dental problem. Here are the top underlying causes for loose teeth.
Gum disease. Teeth are held in place by an elastic tissue called the periodontal ligament. But advanced periodontal (gum) disease, a bacterial infection usually caused by film buildup on teeth called dental plaque, can damage the ligament and cause it to detach. If it's not treated, it could lead to tooth loss.
Bite-related trauma. A normal bite helps balance out the forces generated when we chew so they don't damage the teeth. But if a misaligned tooth protrudes higher from the jaw, the opposing tooth will likely create more downward pressure on it while chewing. This can stress the tooth's supporting ligament to the point of looseness.
Self-inflicted trauma. While they may be trendy, tongue jewelry can cause dental damage. A wearer who clicks the “barbell” of a tongue stud against their teeth could be creating conditions conducive for gum damage and bone loss, which can cause tooth looseness. Similarly, taking orthodontics into your own hands could also damage your teeth, especially if you have undiagnosed gum disease.
Genetics. Although you can't prevent it, the type of resistance or susceptibility you inherited from your parents (as well as your dental anatomy) can cause you dental problems. Thinner gum tissues, especially around the roots, can make you more susceptible to gum disease or dental trauma, which in turn could contribute to tooth looseness.
There are things you can do to lessen your chance of loose teeth. Brush and floss every day to remove disease-causing bacterial plaque and see a dentist regularly for cleanings to reduce your risk of gum disease. If you have any misaligned teeth, consult with an orthodontist about possible treatment. And avoid oral jewelry and DIY orthodontics.
If you do notice a loose tooth, see us as soon as possible. We'll need to diagnose the underlying cause and create a treatment plan for it. We may also need to splint the tooth to its neighbors to stabilize it and reduce your risk of losing it permanently.
