We're all interested in how our toothpaste tastes, how it freshens breath or how it brightens teeth. But those are secondary to its most important function, which is how well our toothpaste helps us remove dental plaque, that thin bacterial film on teeth most responsible for both tooth decay and gum disease.
Daily brushing and flossing clear away dental plaque, resulting in a much lower risk for dental disease. But while the mechanical action of brushing loosens plaque, toothpaste helps complete its removal. It can do this because of two basic ingredients found in nearly every brand of toothpaste.
The first is an abrasive (or polishing agent), a gritty substance that boosts the effectiveness of the brushing action (which, by the way, alleviates the need for harmful aggressive brushing). These substances, usually hydrated silica, hydrated alumina or calcium carbonate, are abrasive enough to loosen plaque, but not enough to damage tooth enamel.
The other ingredient, a detergent, works much the same way as the product you use to wash greasy dishes—it breaks down the parts of plaque that water can't dissolve. The most common, sodium lauryl sulfate, a safe detergent found in other hygiene products, loosens and dissolves plaque so that it can be easily rinsed away.
You'll also find other ingredients to some degree in toothpaste: flavorings, of course, that go a long way toward making the brushing experience more pleasant; humectants to help toothpaste retain moisture; and binders to hold bind all the ingredients together. And many toothpastes also contain fluoride, a naturally-occurring chemical that strengthens tooth enamel.
You may also find additional ingredients in toothpastes that specialize in certain functions like reducing tartar buildup (hardened plaque), easing tooth or gum sensitivity or controlling bacterial growth. Many toothpastes also include whiteners to promote a brighter smile. Your dentist can advise you on what to look for in a toothpaste to meet a specific need.
But your first priority should always be how well your toothpaste helps you keep your teeth and gums healthy. Knowing what's in it can help you choose your toothpaste more wisely.

If you think brushing and flossing and regular dental visits are all you need to do to avoid dental disease, you're missing a key component in your prevention plan. What you eat could also help close the door on tooth decay or gum disease—or open it even wider if you're eating nutritionally deficient foods.
Let's look first at the latter scenario. Like us, the oral bacteria most responsible for dental disease also have to eat to survive and thrive. And, often like us, they have a favorite food—provide them ample amounts of that and they'll continue to multiply and raise your risk of disease.
That favorite bacterial food is simple carbohydrates, particularly refined sugar. A diet heavy in added sugar can increase oral bacteria, which in turn elevates your chances of a gum infection. Bacteria's main by-product, acid, may also increase. That's bad news for your teeth. At high levels, acid contact softens and erodes enamel, the precursor to tooth decay.
Obviously, then, a "tooth-friendly" diet should be low on sugar and other simple carbohydrates like refined breads, pasta or pastries. Soda, energy and sports drinks high in both sugar and acid should also be avoided or restricted to mealtimes. You should also be careful with how much fruit you're eating as their natural sugars can also feed bacteria.
A well-rounded diet, however, isn't simply about avoiding foods—you'll also want to include foods that help you build and maintain healthy teeth and gums. That includes:
- Fiber-rich plant foods: Their fiber reduces the effects of any carbohydrates and they're packed with nutrients;
- Whole grains: Whole grains don't promote decay as refined products do, and chewing them stimulates saliva flow for neutralizing acid;
- Fresh fruits: Eaten in moderation, fruits can provide a bevy of vitamins and minerals. But avoid dried fruits as their sugars are more concentrated;
- Dairy: Milk-based products, particularly cheese, contain nutrients like Vitamin D, calcium and phosphorus, which strengthen teeth against dental disease.
For the most part, a diet that promotes overall well-being will also provide optimum benefits for your dental health. Along with your dental hygiene efforts, eating the right foods can help protect your teeth and gums from both tooth decay and gum disease.

During this year's baseball spring training, Minnesota Twins center fielder Byron Buxton got into a row with a steak dinner—and the beefsteak got the better of it. During his meal, the Gold Glove winner cracked a tooth.
Fortunately, he didn't lose it. Buxton's dentist rescued the tooth with a dental procedure that's been around for over a century—a root canal treatment. The dependable root canal is responsible for saving millions of teeth each year.
Dentists turn to root canal treatments for a number of reasons: a permanent tooth's roots are dissolving (a condition called resorption); chronic inflammation of the innermost tooth pulp due to repeated fillings; or a fractured or cracked tooth, like Buxton's, in which the pulp becomes exposed to bacteria.
One of the biggest reasons, though, is advanced tooth decay. Triggered by acid, a by-product of bacteria, a tooth's enamel softens and erodes, allowing decay into the underlying dentin. In its initial stages, we can often treat decay with a filling. But if the decay continues to advance, it can infect the pulp and root canals and eventually reach the bone.
Decay of this magnitude seriously jeopardizes a tooth's survival. But we can still stop it before that point with a root canal. The basic procedure is fairly straightforward. We begin first by drilling a small hole into the tooth to access the inner pulp and root canals. Using special instruments, we then remove all of the infected tissue within the tooth.
After disinfecting the now empty spaces and reshaping the root canals, we fill the tooth with a rubber-like substance called gutta percha. This, along with filling the access hole, seals the tooth's interior from future infection. In most cases, we'll return sometime later and bond a life-like crown to the tooth (as Buxton's dentist did for him) for added protection and support.
You would think such a procedure would get its own ticker tape parade. Unfortunately, there's a cultural apprehension that root canals are painful. But here's the truth—because your tooth and surrounding gums are numbed by local anesthesia, a root canal procedure doesn't hurt. Actually, if your tooth has been throbbing from tooth decay's attack on its nerves, a root canal treatment will alleviate that pain.
After some time on the disabled list, Buxton was back in the lineup in time to hit his longest homer to date at 456 feet on the Twins' Opening Day. You may not have that kind of moment after a root canal, but repairing a bothersome tooth with this important procedure will certainly get you back on your feet again.

It's normal to have occasional mouth dryness—that "cotton mouth" feeling when you first wake up or after eating a spicy meal. It soon dissipates, though, leaving you no worse for wear other than the memory of an unpleasant sensation.
For some, though, the unpleasant sensation becomes a chronic condition known as xerostomia, in which their mouth feels dry most of the time. And, it can have far-reaching consequences beyond a mere irritation if not treated.
Among the numerous causes for xerostomia, the most common appears to be over-the-counter and prescription medication. An estimated five hundred medications have dry mouth as a potential side-effect, from antihistamines to antidepressants. And because people over 65 are more likely to take medications, they also have a high occurrence of xerostomia.
A person with certain systemic diseases like Parkinson's Disease or undergoing radiation or chemotherapy for cancers of the head and neck may also encounter dry mouth. For example, an autoimmune disease called Sjögren's syndrome, primarily affecting postmenopausal women, can dry out the mouth's mucous membranes.
Chronic dry mouth isn't normal, and often a sign of a health problem that should be examined. And it can lead to more problems with your oral health. Because dry mouth is most likely a reduction in saliva, which helps buffer decay-causing acid and provides antibodies to fight bacteria, having less of this vital fluid can increase your risk for both tooth decay and gum disease.
So, what can you do if you're plagued by persistent dry mouth? If you suspect your medications may be a factor, talk with your doctor about whether one of them may be the underlying cause for your symptoms. You may be able to switch to an alternate medication without dry mouth side-effects.
You can also increase your water intake during the day, including drinking more before and after taking medication. And there are a number of products like the artificial sweetener xylitol found in gums and candies that can boost saliva. Your dentist may also be able to recommend products that increase saliva.
Above all, be sure you keep up daily brushing and flossing, as well as regular dental cleanings. Taking care of chronic dry mouth could help you avoid dental problems later.

If you like conundrums like "Which came first? The chicken or the egg?", then you may enjoy this one: "Which should you do first, brush or floss?"
Both of these oral hygiene tasks are equally important for removing dental plaque, a thin bacterial film that forms on teeth after eating. Removing plaque on a daily basis minimizes your risk for developing tooth decay or periodontal (gum) disease, the top causes for tooth loss. Brushing removes plaque from broad tooth surfaces, while flossing removes it from between teeth where brushing can't reach.
There is wide consensus that you need both brushing and flossing to thoroughly remove plaque. But there is a debate over which of these two tasks you should do first for the most effective outcome. Those debates are more or less good-natured, but there are proponents on both sides on which task should come first.
Those on the "Brush First" side say brushing initially gets the bulk of accumulated plaque out of the way. If you floss first, you may be plowing through a lot of soft plaque, which can quickly turn your floss into a gunky mess. More importantly, you may only be moving plaque around with the floss, not actually removing it. By brushing first, there's less plaque to deal with when flossing.
"Floss First" folks, though, say flossing before you brush loosens plaque stuck between teeth that can be more easily brushed away. But perhaps a more important reason is psychological: People don't really like flossing as much as brushing. Because of this, putting it off to the end may mean it doesn't happen; doing it first will help ensure it actually gets done.
In the end, though, the order you perform these tasks comes down to personal preference. You can try both ways to see which one suits you best. The important thing, however, is that you do both tasks—if you do, you can greatly lower your risk of dental disease that could rob you of your teeth.
