In the early Eighties, dentists began noticing symptoms among a few patients that indicated something far more serious. They were, in fact, among the first healthcare providers to recognize what we now know as HIV-AIDS.
Today, about 1.2 million Americans have contracted the Human Immunodeficiency Virus (HIV). It’s a retrovirus, somewhat different than other viruses: it can invade immune system cells and hijack their replication mechanism to reproduce itself. Untreated it eventually destroys these cells to give rise to the more serious, life-threatening disease Acquired Immunodeficiency Syndrome (AIDS).
Thanks to antiretroviral drugs, most HIV positive patients live somewhat normal lives and avoid the more serious Acquired Immunodeficiency Syndrome (AIDS). But while antiretroviral therapy effectively inhibits the action of the virus, it isn’t a cure — the virus is a permanent resident of the body and can still affect health, especially in the mouth.
In this regard, one of the more common conditions associated with HIV is Candidiasis, a fungal infection also known as thrush, which causes cracking of the mouth corners and lesions or white patches on the surface of the tongue or roof of the mouth. HIV patients may also experience limited saliva flow that causes dry mouth (xerostomia) with effects that range from bad breath to a higher risk of tooth decay.
The most serious effect, though, of HIV on oral health is the body’s lower resistance to fight periodontal (gum) disease. HIV patients are especially susceptible to a severe form known as Necrotizing Ulcerative Periodontitis (NUP), a sign as well of immune system deterioration and the beginning of AIDS. This painful condition causes gum ulcerations, extensive bleeding, and the rapid deterioration of gum attachment to teeth.
If you or a family member is HIV positive, you’ll need to pay close attention to oral health. Besides diligent brushing and flossing, you or they should also regularly visit the dentist. These visits not only provide diagnosis and treatment of dental problems, they’re also an important monitoring point for gauging the extent of the HIV infection.
Taking care of dental problems will also ease some of the discomfort associated with HIV. Thanks to proper oral care, you or someone you love can experience a higher quality of life.
Dental implants are today’s preferred choice for replacing missing teeth. They’re the closest restoration to natural teeth—but at a price, especially for multiple teeth. If implants are beyond your current financial ability, there’s an older, more affordable option: a removable partial denture (RPD).
Similar in concept to a full denture, a RPD replaces one or more missing teeth on a jaw. It usually consists of a lightweight but sturdy metal frame supporting a resin or plastic base (colored pink to mimic gum tissue). Prosthetic (false) teeth are attached to the base at the locations of the missing teeth. Unlike transitional dentures, RPDs are designed to last for many years.
Although simple in concept, RPDs certainly aren’t a “one-size-fits-all” option. To achieve long-term success with an RPD we must first consider the number of missing teeth and where they’re located in the jaw. This will dictate the type of layout and construction needed to create a custom RPD.
In addition, we’ll need to consider the health and condition of your remaining teeth. This can be important to an RPD’s design, especially if we intend to use them to support the RPD during wear. Support is a fundamental concern because we want to prevent the RPD from excessively moving in place.
Besides dental support we’ll also need to take into account how the jaws function when they bite. The RPD’s design should evenly distribute the forces generated when you eat and chew so as not to create undue pressure on the bony ridges of the jaw upon which the RPD rests. Too much pressure could accelerate bone loss in the jaw, a common issue with dentures.
It takes a lot of planning to create a comfortably-fitting RPD with minimal impact on your dental health. But you’ll also have to maintain it to ensure lasting durability. You should clean your RPD daily, as well as brush and floss the rest of your teeth to minimize the chances of developing tooth decay or periodontal (gum) disease. You can further discourage disease-causing bacterial growth by removing them at night while you sleep.
A RPD can be a viable alternative to more expensive restorations. And with the right design and proper care it could serve you and your smile for a long time to come.

Academy Award-winning actress Kathy Bates knows how important it is to present your best face to the world — and one of the most important features of that face is a beaming smile. But there came a point when she noticed something was a little off. “I've always had good teeth, but it seemed to me as I was getting older that they weren't looking as good,” Kathy explained in a recent interview with Dear Doctor magazine.
That's when she decided it was time to take action. Kathy had orthodontic treatment when she was in her fifties, and she keeps her smile bright with tooth whitening treatments. She uses a kit provided by her dentist with a safe, effective whitening solution.
Of course, a bright, healthy smile looks great anywhere — whether you're on the red carpet or “off the grid.” And you don't have to be a Hollywood star to have professional whitening treatments. In fact, teeth whitening is one of the most popular and affordable cosmetic treatments modern dentistry offers.
The basic options for professional teeth whitening include in-office bleaching or take-home kits. Both types of dentist-supervised treatments offer a safe and effective means of getting a brighter smile; the main difference is how long they take to produce results. A single one-hour treatment in the office can make your teeth up to ten shades lighter — a big difference! To get that same lightening with at-home trays, it would take several days. On the plus side, the take-home kit is less expensive, and can achieve the same results in a bit more time.
It's important to note that not all teeth can be whitened with these treatments. Some teeth have intrinsic (internal) stains that aren't affected by external agents like bleaches. Also, teeth that have been restored (with bonding or veneers, for example) generally won't change color. And you can't necessarily whiten your teeth to any degree: Every tooth has a maximum whiteness, and adding more bleach won't lighten it beyond that level. Most people, however, find that teeth whitening treatments produce noticeable and pleasing results.
What about those off-the-shelf kits or in-the-mall kiosks? They might work… or they might not. But one thing's for sure: Without a dentist's supervision, you're on your own. That's the main reason why you should go with a pro if you're considering teeth whitening. We not only ensure that your treatment is safe — we can also give you a realistic idea of what results to expect, and we will make sure that other dental problems aren't keeping you from having a great-looking smile.
How often does Kathy Bates see her dentist for a checkup and cleaning? “I go about every four months,” she noted. “I'm pretty careful about it.” And if you've seen her smile, you can tell that it pays off.
