We’ve come a long way since the early 1980s when we first identified the HIV virus. Although approximately 35 million people worldwide (including a million Americans) now have the virus, many are living relatively long and normal lives thanks to advanced antiretroviral drugs.
Still, HIV patients must remain vigilant about their health, especially their oral health. In fact, problems with the teeth, gums and other oral structures could be a sign the virus has or is moving into the full disease stage, acquired immunodeficiency syndrome (AIDS). That’s why you or a loved one with the virus should maintain regular dental checkups or see your dentist when you notice any oral abnormalities.
One of the most common conditions among HIV-positive patients is a fungal infection called candidiasis (or “thrush”). It may appear first as deep cracks at the corners of the mouth and then appear on the tongue and roof of the mouth as red lesions. The infection may also cause creamy, white patches that leave a reddened or bleeding surface when wiped.
HIV-positive patients may also suffer from reduced salivary flow. Because saliva helps neutralize excess mouth acid after we eat as well as limit bacterial growth, its absence significantly increases the risk of dental disease. One of the most prominent for HIV-positive patients is periodontal (gum) disease, a bacterial infection normally caused by dental plaque.
While gum disease is prevalent among people in general, one particular form is of grave concern to HIV-positive patients. Necrotizing ulcerative periodontitis (NUP) is characterized by spontaneous gum bleeding, ulcerations and a foul odor. The disease itself can cause loosening and eventually loss of teeth, but it’s also notable as a sign of a patient’s deteriorating immune system. The patient should not only undergo dental treatment (including antibiotics), but also see their primary care physician for updates in treating and managing their overall symptoms.
Above all, HIV-positive patients must be extra diligent about oral hygiene, including daily brushing and flossing. Your dentist may also recommend other measures like saliva stimulators or chlorhexidine mouthrinses to reduce the growth of disease-causing bacteria. Together, you should be able to reduce the effects of HIV-induced teeth and gum problems for a healthier mouth and better quality of life.

What makes an attractive smile? Of course, shiny, straight and defect-free teeth are a big factor. But there’s another equally important element: all your teeth have come in.
Sometimes, though, they don’t: one or more teeth may remain up in the gums, a condition known as impaction. And if they’re in the front like the upper canines (the pointed teeth on either side of the front four incisors) your smile’s natural balance and symmetry can suffer.
Impaction usually happens due to lack of space on a small jaw. Previously erupted teeth crowd into the space of teeth yet to come in, preventing them from doing so. As a result the latter remain hidden within the gums.
While impaction can interfere with the smile appearance, it can cause health problems too. Impacted teeth are at higher risk for abscesses (localized areas of infection) and can damage the roots of other teeth they may be pressing against. That’s why it’s desirable for both form and function to treat them.
We begin first with an orthodontic examination to fully assess the situation. At some point we’ll want to pinpoint the impacted teeth’s precise location and position. While x-rays are useful for locating impacted teeth, many specialists use cone beam CT (CBCT) technology that produces highly detailed three-dimensional images viewable from different vantage points.
If the tooth is in too extreme a position, it might be best to remove it and later replace it with a dental impact or similar restoration once we’ve completed other necessary orthodontic treatment. But if the tooth is in a reasonable position, we might be able to “move” the tooth into its proper place in the jaw in coordination with these other tooth-movement efforts to make room for it.
To begin this process, an oral surgeon or periodontist surgically exposes the tooth crown (the normally visible portion) through the gums. They then bond a small bracket to the crown and attach a small gold chain. An orthodontist will attach the other end to orthodontic hardware that will exert downward pressure on the tooth to gradually bring it into normal position.
Dealing with impacted teeth of this nature is often part of a comprehensive effort to correct the bite. If we’re successful, it could permanently transform both the smile and overall dental health.
