Acquired Immune Deficiency Syndrome (AIDS) jolted our collective consciousness in the 1980s. The deadly disease caused by the human immunodeficiency virus (HIV) had no known cure and, at the time, no effective treatment.
HIV is a retrovirus, a virus with a genetic makeup and reproduction system differing from other kinds. After taking up permanent residency in the body, HIV begins “hijacking” the replication process of cells in the body's immune system and replacing it with a copy of its own. This destroys the cells' ability to protect the body from hostile organisms. As the virus affects more and more cells, the patient's condition ultimately develops into AIDS.
An estimated 35 million people worldwide (1.2 million in the U.S.) are currently infected with the virus. Thanks to new antiretroviral drugs, though, HIV can be kept from accelerating into AIDS. While their condition remains serious, many HIV positive patients can now live long and relatively normal lives. Even so, having the virus requires them to pay close attention to their health, including their mouth.
Even while stalled from becoming AIDS, HIV can still cause oral problems for 30 to 80% of patients. The fungal infection candidiasis (also known as thrush) is the most common of these problems, which appears as lesions, cracking skin or creamy white patches on the tongue or palate that easily bleed. Patients also have higher risks for dry mouth, oral cancer and periodontal (gum) disease.
HIV positive patients must practice diligent daily oral care and see their dentist for checkups regularly. Prevention, early diagnosis and treatment can keep gum disease and other damaging conditions under control. Monitoring oral health is also important because certain mouth conditions could be an early sign the infection is entering a new advanced stage in the body that requires additional attention.
Keeping vigilant in all aspects of health is a way of life for someone with HIV. Such vigilance, though, can help them maintain a healthy mouth and even prolong their life.
Although dental care has made incredible advances over the last century, the underlying approach to treating tooth decay has changed little. Today’s dentists treat a decayed tooth in much the same way as their counterparts from the early 20th Century: remove all decayed structure, prepare the tooth and fill the cavity.
Dentists still use that approach not only because of its effectiveness, but also because no other alternative has emerged to match it. But that may change in the not-too-distant future according to recent research.
A research team at Kings College, London has found that a drug called Tideglusib, used for treating Alzheimer’s disease, appears to also stimulate teeth to regrow some of its structure. The drug seemed to cause stem cells to produce dentin, one of the tooth’s main structural layers.
During experimentation, the researchers drilled holes in mouse teeth. They then placed within the holes tiny sponges soaked with Tideglusib. They found that within a matter of weeks the holes had filled with dentin produced by the teeth themselves.
Dentin regeneration isn’t a new phenomenon, but other occurrences of regrowth have only produced it in tiny amounts. The Kings College research, though, gives rise to the hope that stem cell stimulation could produce dentin on a much larger scale. If that proves out, our teeth may be able to create restorations by “filling themselves” that are much more durable and with possibly fewer complications.
As with any medical breakthrough, the practical application for this new discovery may be several years away. But because the medication responsible for dentin regeneration in these experiments with mouse teeth is already available and in use, the process toward an application with dental patients could be relatively short.
If so, a new biological approach to treating tooth decay may one day replace the time-tested filling method we currently use. One day, you won’t need a filling from a dentist—your teeth may do it for you.
A certain news story a few years ago notwithstanding, dentists still recommend flossing along with brushing to adequately remove disease-causing plaque. If there is any controversy at all about flossing, it's whether you should perform it before brushing or after. Each perspective has good reasons.
"Brush First" proponents say their way encourages the formation of a daily hygiene habit, a must for preventing disease. That's because brushing can remove most of the plaque built up on the teeth, while flossing can then remove what's left. If you floss first, though, you'll have to plow through the sticky film with the floss, which can be an unpleasant experience. Facing that every day could make a person less enthusiastic about developing a hygiene habit.
But it's not just about the sensation: depending on the person, the plaque buildup could be so much that the floss becomes clogged with it. You're then moving the plaque rather than removing it. Brushing a lot of the plaque out of the way first will increase the cleaning power of your floss.
The "Floss First" team, though, is undaunted with their own take on the matter. Flossing can loosen up any stuck debris between teeth, making it easier for brushing to clear it away. It can also expose plaque-covered areas between teeth to allow better contact with the fluoride in your toothpaste. And, the amount of plaque you're pulling out in certain areas during flossing could tip you off to beef up your brushing efforts on those areas of heavier plaque accumulation.
One of the prime reasons for flossing first, though, goes back to the comfort factor and human nature. To be honest, for most people flossing isn't as much "fun" as brushing. If you put it off until after brushing, you're more likely not to do it if you find it unpleasant. Doing it first gets the less likeable task out of the way, so you can then do the more likeable one, brushing.
Which approach is best for you? It's really a personal decision, one you can discuss with your dentist. Try both ways, and see which one seems better. But whether you floss first or last, do floss to really reduce your risk for dental disease.

As a regular part of your daily hygiene you may be using a mouthrinse — or “mouthwash” — mainly to keep your mouth feeling fresh and clean. Some mouthrinses, though, do more than give you fresher breath.
While there are countless mouthrinses available, we can place all of them into two broad categories: cosmetic and therapeutic. The first refresh your mouth and breath, usually with a mentholated or minty taste and smell that masks unpleasant odors. How well they work is mainly subjective: if you feel better after using them, they’ve done their job.
Therapeutic rinses have a different role, intended to improve oral health in some way. We can divide these into anti-cariogenic (decay prevention) or anti-bacterial rinses. You can find fluoride-based anti-cariogenic rinses over-the-counter in retail or drug stores, usually containing about .05% sodium fluoride per volume. Numerous studies have shown these rinses highly effective in preventing tooth decay when used with daily brushing and flossing.
Likewise, over-the-counter antibacterial rinses have proven somewhat effective in reducing bacteria that leads to dental disease. Formulated usually with triclosan, sanguinaria extract, zinc or essential oils, they can also help reduce the incidence of gingivitis (inflammation of the gums), but only if used in conjunction with brushing and flossing.
Perhaps, though, the most widely studied and substantiated therapeutic mouthrinse is chlorhexidine, a prescription-only rinse. Chlorhexidine inhibits the formation of bacterial plaque on tooth surfaces, the main trigger for both tooth decay and periodontal (gum) disease. It’s often used as a post-surgery rinse when brushing and flossing may not be possible, but dentists will often prescribe it for patients who have a high propensity for dental disease.
Using a mouthrinse depends on your current oral health and personal preferences. Therapeutically, most people gain some added tooth strength protection from using a fluoride rinse in their daily hygiene. If fresh breath and the way your mouth feels are important to you, you should consider such a rinse that also has a pleasant taste and effect for you. We can further discuss with you whether a different type of rinse, or a prescription-strength formula, might be best for your particular needs.

It’s been widely established for decades that cigarette smoking contributes to cancer and heart disease. But did you know smoking will also increase your risk of tooth decay and periodontal (gum) disease, as well as nuisance problems like tooth staining, bad breath and diminished taste perception?
Its effects on your teeth and mouth are all the more reason to quit smoking. But deciding and following through are two different things: many smokers find it painfully difficult to quit due to their addiction to nicotine, tobacco’s active ingredient.
But while difficult, it can be done. Here are 4 tips to help you follow through on your decision to quit smoking.
Change Your Response to Stress. Cigarette smoking is closely tied to the pleasure and reward areas of your brain. With its “hit” of nicotine, you sub-consciously identify smoking as a way to relieve the unpleasant feelings of stress. Instead, substitute other stress relievers when it occurs: going for a walk, talking to a friend or taking a few deep breaths. In time, this substitution will wear down the trigger response to stress you’ve developed with smoking.
Gradually Reduce Nicotine. You don’t have to quit abruptly or “cold turkey”: over the course of a few weeks, try switching to brands with decreasing levels of nicotine. Each week change to a brand with 0.2-0.4 milligrams less nicotine yield than the brand you were smoking the previous week. When you reach the lowest nicotine yield you can find, begin reducing the number of cigarettes you smoke each day. You can find a list of nicotine yields by brand at www.erowid.org/plants/tobacco/tobacco_nic.shtml.
Quitting Loves Company. While you’re responsible for quitting, you may also benefit from the support of others. Usually eight to ten weeks of peer group sessions, a cessation support group provides instruction and ample structure with others engaged in the same struggle. You can usually locate one of these support groups by asking your healthcare provider.
Talk to Your Doctor or Dentist. Next to you or your family, no one wants you to quit more than we do! We can provide you information, treatment and encouragement as you take this big step toward improving your life and health.
