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.
When die-hard music fans hear that their favorite performer is canceling a gig, it’s a big disappointment—especially if the excuse seems less than earth-shaking. Recently, British pop sensation Dua Lipa needed to drop two dates from her world tour with Bruno Mars. However, she had a very good reason.
“I’ve been performing with an awful pain due to my wisdom teeth,” the singer tweeted, “and as advised by my dentist and oral surgeon I have had to have them imminently removed.”
The dental problem Lipa had to deal with, impacted wisdom teeth, is not uncommon in young adults. Also called third molars, wisdom teeth are the last teeth to erupt (emerge from beneath the gums), generally making their appearance between the ages of 18-24. But their debut can cause trouble: Many times, these teeth develop in a way that makes it impossible for them to erupt without negatively affecting the healthy teeth nearby. In this situation, the teeth are called “impacted.”
A number of issues can cause impacted wisdom teeth, including a tooth in an abnormal position, a lack of sufficient space in the jaw, or an obstruction that prevents proper emergence. The most common treatment for impaction is to extract (remove) one or more of the wisdom teeth. This is a routine in-office procedure that may be performed by general dentists or dental specialists.
It’s thought that perhaps 7 out of 10 people ages 20-30 have at least one impacted wisdom tooth. Some cause pain and need to be removed right away; however, this is not always the case. If a wisdom tooth is found to be impacted and is likely to result in future problems, it may be best to have it extracted before symptoms appear. Unfortunately, even with x-rays and other diagnostic tests, it isn’t always possible to predict exactly when—or if—the tooth will actually begin causing trouble. In some situations, the best option may be to carefully monitor the tooth at regular intervals and wait for a clearer sign of whether extraction is necessary.
So if you’re around the age when wisdom teeth are beginning to appear, make sure not to skip your routine dental appointments. That way, you might avoid emergency surgery when you’ve got other plans—like maybe your own world tour!

We often don't realize how important something is until it's gone. Like saliva: you're usually not aware that it's cleaning the mouth, neutralizing mouth acid or helping with digestion. But that could change if your saliva flow drops below normal: your health may soon suffer with your mouth taking the brunt.
In particular, reduced saliva flow increases your risk for tooth decay and periodontal (gum) disease. Both diseases are linked to oral bacteria. While many of the myriad strains in the mouth are beneficial, a few bacteria can infect and inflame gum tissues. Bacteria also produce acid, which can soften and erode enamel and make the teeth more susceptible to decay.
Saliva inhibits bacteria in a number of ways. It first clears the mouth of leftover food so not as much stays behind to form bacterial plaque, a thin film of food particles that builds up on teeth. You still need to brush and floss daily to remove plaque, but it's less effective without saliva's cleansing action. Saliva also contains antibodies that destroy disease-causing bacteria and other organisms, which keeps their populations in the mouth low.
One of saliva's most important functions, though, is buffering acid. The mouth's ideal pH level is neutral, but many foods we eat can cause it to become more acidic.Â Even a slight acidic rise after eating can soften the minerals in enamel. But saliva goes to work immediately and usually restores normal pH within a half hour to an hour. It also aids in re-mineralizing the enamel.
For these reasons, it's important for you to find out the cause of chronic dry mouth and treat it. If it's a side effect of your medication, talk to your doctor about an alternative, or drink more water before and after you take your dose. Certain products can also stimulate saliva flow, like chewing gum with xylitol, an alcohol-based sweetener that has dental health-protecting properties too.
Although you often don't notice this unsung bodily fluid swishing in your mouth, it's important that you take care of it. Keeping your saliva flowing will help ensure better oral health.

While oral hygiene, a nutritious diet and regular dental visits are all crucial to long-term oral health, these efforts complement what your body already does to keep your mouth healthy. One of the major players in this function is saliva.
Produced by hundreds of glands located throughout the mouth, saliva does much more than help you swallow and wash away food. As you chew, an enzyme in saliva known as amylase breaks down starches in your food to make it easier to digest in the stomach. Saliva also contains antibodies, similar to what’s in tears, which can fight bacteria and other disease-causing organisms.
Perhaps its most important function, though, is its ability to protect and maintain healthy tooth enamel. The strongest substance in the body, enamel nevertheless has one primary enemy — the acid found in certain foods or as a byproduct of bacteria feeding on sugar and other carbohydrates.
When the ideally neutral pH level of the mouth becomes too acidic (nearly every time you eat), minerals in the enamel begin to soften and dissolve. The increased saliva flow when we eat floods the mouth with buffering agents that neutralize the acid and restore the mouth’s normal pH level. Not only does saliva stop demineralization, but it also restores a good bit of the enamel’s mineral content.
In recent years, a new role for saliva has begun to emerge as a means to diagnose disease. Like blood, urine and other bodily fluids, saliva contains molecules that serve as biological markers for disease. Given the right equipment, saliva has the potential to indicate early signs of cancer (including oral), diabetes and other systemic conditions. As the means to examine saliva for these markers increases it promises to be easier and less expensive to collect and sample than blood, while reducing the chances of transmitting bloodborne diseases to healthcare workers.
It’s a lot to consider with this fluid that you hardly notice, except when it isn’t there. Saliva is proof that our efforts at keeping our mouths healthy cooperate and depend on our bodies’ amazing systems.

Preventing tooth decay is mostly about the basics: daily brushing and flossing followed by regular dental cleanings and checkups. But there’s also a bigger picture: your own personal risk profile for decay based on factors you can modify directly — and those you can’t.
The first type of factor usually involves habits and behavior that either work with your mouth’s natural defenses to fight decay or against it. Besides regular hygiene, your diet is probably the most important of these you can modify for better dental health.
A diet rich in fresh vegetables, protein and dairy products boosts strong, healthy teeth resistant to decay. Conversely, bacteria thrive on the sugar in many snack foods, while sodas, sports or energy drinks elevate acid levels that soften and erode the minerals in your teeth’s enamel.
Lifestyle habits like tobacco use or excessive alcohol consumption also increase your decay risk. Not only do they promote plaque buildup (the thin film of bacteria and food particles that feeds the decay process), but tobacco especially can impede the body’s natural prevention and healing properties.
Conscientious hygiene practices, a dental-friendly diet and modified lifestyle habits all can help you prevent decay. But diligence may not be enough — there are other possible factors you can’t control or may find difficult to change. For example, you may have a genetic propensity toward certain bacteria that cause decay. You may have a condition like gastric reflux that increases the mouth’s acid level. You may also be taking medications that reduce saliva flow, the mouth’s natural acid neutralizer.
But if we know which of these indirect risk factors affect you, we can compensate with extra measures. If enamel strength is a problem we can topically apply fluoride; we can also reduce chronic bacterial levels with prescription rinses. If you have restricted saliva flow, we can attempt to modify your prescriptions through your doctor or prescribe aids that increase saliva.
The key is to investigate your complete risk factor profile through a thorough dental examination. Once we know everything about your mouth, life and health that increases your decay risk, we can put in place a balanced strategy of prevention and treatment just for you. Doing so will greatly increase your chances for keeping your teeth decay-free and healthy.
