In recent decades civilization's millennia-long search for clean, safe drinking water has become much easier with modern purification methods. Today, there are few places in the United States without adequate access to potable water. And about three-fourths of the nation's tap water systems add fluoride, credited with helping to reduce tooth decay over the past half century.
But in recent years some have voiced concerns about the safety of tap water and popularizing an alternative: bottled water. Manufacturers of bottled water routinely market their products as safer and healthier than what comes out of your faucet.
But is that true? A few years ago a non-profit consumer organization called the Environmental Working Group (EWG) performed a detailed, comprehensive study of bottled water. Here's some of what they found.
Lack of transparency. It's not always easy to uncover bottled water sources (in some cases, it might actually begin as tap water), how it's processed, or what's in it. That's because unlike water utilities, which are rigorously monitored by the Environmental Protection Agency (EPA), the Food and Drug Administration (FDA) oversees bottled water production with less strenuous guidelines on labeling. Eight out of the top 10 selling brands were less than forthcoming about their water's contents in EWG's investigation.
Higher cost. According to the EPA, the average consumer cost in the last decade for tap water was $2.00 per 1,000 gallons (0.2 cents per gallon). The retail cost for even bulk bottled water is exponentially higher. It can be a costly expenditure for a family to obtain most of their potable water by way of bottled—while still paying for tap water for bathing and other necessities.
Environmental impact. Bottled water is often marketed as the better environmental choice. But bottled water production, packaging and distribution can pose a significant environmental impact. EWG estimated the total production and distribution of bottled water consumes more than 30 million barrels of oil each year. And disposable plastic water bottles have become one of the fastest growing solid waste items at about 4 billion pounds annually.
While there are credible concerns about tap water contaminants, consumers can usually take matters into their own hands with an affordable and effective household filtering system. EWG therefore recommends filtered tap water instead of bottled water for household use.

The market for sugar alternatives has grown exponentially since saccharin was accidentally discovered in 1878. Today, saccharin has been joined by other FDA-approved zero-calorie artificial sweeteners, including aspartame (“Equal®” or “NutraSweet®”), sucralose (“Splenda®”) and rebaudioside A, derived from the stevia plant. You can also choose low-calorie alcohol sugars like erythritol or xylitol.
With rare exceptions, all these choices are widely considered safe substitutes for table sugar, high fructose corn syrup or other versions of this plentiful carbohydrate. Finding substitutes for sugar is a worthy health goal: besides its role in obesity, sugar is considered a contributing factor in cardiovascular disease and diabetes.
It's also a prime food for oral bacteria that cause dental disease. As bacteria consume sugar they produce acid as a byproduct. Acid softens and dissolves the mineral content in enamel, leading to erosion and the formation of cavities. While saliva normally neutralizes acid after we eat, constant snacking and higher quantities of sugar in our food make it difficult for it to control or neutralize acid in the oral environment.
Because most of us are hard-wired with a “sweet tooth,” it's difficult for many to cut back on sugar. Artificial sweeteners help reduce the amount of sugar in the diet with obvious benefits for general health. It can also make a big difference in your dental health by helping you prevent tooth decay.
One alcohol sugar may even go a step further. In addition to reducing the presence of sugar in the mouth, xylitol (found in chewing gums, candy and breath mints) also seems to reduce bacterial growth by interfering with their ability to ferment the sugar.
If you're considering using an artificial sweetener, get to know them first: some like aspartame aren't suitable for baked goods or cooking, while saccharine or sucralose are. People with a rare genetic condition called phenylketonuria also can't properly process aspartame in the body.
Be sure you also talk to us about artificial sweeteners' impact on oral health, especially the benefits of xylitol for dental care. Used in a wise and informed way, these sugar alternatives can improve both your oral and general health.

Implant-supported fixed bridges are growing in popularity because they offer superior support to traditional bridges or dentures. They can also improve bone health thanks to the affinity between bone cells and the implants' titanium posts.
Even so, you'll still need to stay alert to the threat of periodontal (gum) disease. This bacterial infection usually triggered by dental plaque could ultimately infect the underlying bone and cause it to deteriorate. As a result the implants could loosen and cause you to lose your bridgework.
To avoid this you'll need to be as diligent with removing plaque from around your implants as you would with natural teeth. The best means for doing this is to floss around each implant post between the bridgework and the natural gums.
This type of flossing is quite different than with natural teeth where you work the floss in between each tooth. With your bridgework you'll need to thread the floss between it and the gums with the help of a floss threader, a small handheld device with a loop on one end and a stiff flat edge on the other.
To use it you'll first pull off about 18" of dental floss and thread it through the loop. You'll then gently work the sharper end between the gums and bridge from the cheek side toward the tongue. Once through to the tongue side, you'll hold one end of the floss and pull the floss threader away with the other until the floss is now underneath the bridge.
You'll then loop each end of the floss around your fingers on each hand and work the floss up and down the sides of the nearest tooth or implant. You'll then release one hand from the floss and pull the floss out from beneath the bridge. Rethread it in the threader and move to the next section of the bridge and clean those implants.
You can also use other methods like specialized floss with stiffened ends for threading, an oral irrigator (or "water flosser") that emits a pressurized spray of water to loosen plaque, or an interproximal brush that can reach into narrow spaces. If you choose an interproximal brush, however, be sure it's not made with metal wire, which can scratch the implant and create microscopic crevices for plaque.
Use the method you and your dentist think best to keep your implants plaque-free. Doing so will help reduce your risk of a gum infection that could endanger your implant-supported bridgework.
