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.
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.

Dental implants are popular with both patients and dentists for their durability and likeness to natural teeth. That natural look, though, can be difficult to attain, especially in what’s known as the “smile zone” — the area of the mouth where teeth are most visible when you smile.
Our biggest concern is the upper front teeth, where the gums are most visible, especially if you smile widely. It takes considerable skill, experience and artistry to position implants in this area so that they appear to naturally emerge from the gums and blend well with other teeth.
To obtain that natural look, we must first assess whether or not there’s enough bone present, which tends to dissolve (resorb) when a tooth is missing, to sufficiently anchor the implant in the right position. There also needs to be sufficient bone around adjacent teeth to support the tiny triangles of gum tissue between teeth called papillae. Without the papillae an unattractive black hole may result between the implant and an adjacent tooth or implant.
Another factor we must consider is the type of gum tissue you have. Everyone generally inherits one of two types of tissue from their parents: thin or thick. The type you have can influence the way the implant appears to emerge from the gums. If you have thick gums, they’re easier to work with and can cover more of the implant. Thinner tissues aren’t quite as easy and are less forgiving if an implant isn’t placed as precisely as possible.
In recent years, improvements in implant design have sought to provide greater stability around bone and gum tissues to offset some of the issues we’ve mentioned. A variation on the design of the top of the implant (where the crown is attached) changes the direction of growth for gum tissues from a horizontal orientation to a vertical one, which can help with the final appearance.
The first step, if you’re considering dental implants for a tooth in the smile zone, is to visit us for a complete examination to see if any of these factors may have an impact on your situation. We can then advise you on the best course of action to achieve the most attractive smile possible.

Each year, over a million Americans venture abroad for healthcare, with roughly half for dental treatment. Cost is the main reason — “medical tourists” believe they can save substantially on treatment, even with travel.
But before undertaking such a venture for dental work, there are some things you should take into consideration. For one, although quality care exists all over the world, you’ll also find different standards of care. In the United States, for example, not only must dental providers graduate from accredited schools, they must also pass state examinations before they can practice (specialists even more). In some parts of the world, educational standards aren’t as difficult to attain. You may also find differing standards for infection control, drug applications or appliances: for example, you may find a lower quality in implant or crown materials or craftsmanship than you might expect in the U.S.
Communication can also be an obstacle. Language barriers make it more difficult to understand what to expect before, during and after a procedure, or to have your questions answered. It may also hinder your provider from fully accessing your medical and dental history, which could have an impact on your treatment and outcome. Limited communication also increases misunderstanding about services offered, charges and treatment expectations.
Finally, many dental procedures have multiple phases to them, some of which normally span several months and visits. Many who go abroad for more complex procedures may try to have them performed in a much shorter time frame. Doing so, however, could prove disappointing both in the quality of the final outcome and your own well-being under such an arduous schedule. Even if your dental work is performed in an exotic locale, recovering from extensive procedures where you must rest and refrain from strenuous activity is best performed in the comfort of your own home.
It’s important to get the facts before traveling to a foreign country for any medical or dental treatment, especially about a region’s accreditation and care standards, as well as what you can expect in terms of amenities and culture during your stay. One good source is the U.S. Center for Disease Control’s web page for medical tourism (http://goo.gl/75iWBk).
Going abroad for dental care is a big decision — be sure you’re prepared.
