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 primary goal of dental care is to preserve teeth. But there are circumstances in which removing a tooth, even a relatively healthy one, could prove best in the long run.
A malocclusion (poor bite) related to crowding might fit such a circumstance. Crowding occurs when the size of the jaw is too small for the teeth coming in. With not enough space, some teeth could erupt out of their proper positions. Removing certain teeth frees up space to eventually allow braces or other orthodontic devices to re-align the teeth.
The teeth most frequently removed are the first bicuspids, located between the cuspid (the "eyeteeth" directly under the eyes) and the back teeth, and the second premolar. Removing these won't normally affect appearance or functionality once orthodontic or cosmetic treatments are complete.
Because of the mechanics of jaw development it might be necessary to perform these extractions several years before orthodontic treatment. This could create another potential problem: the time lag could adversely affect bone health.
This is because bone, as living tissue, has a life cycle with cells forming, functioning and then dissolving, and new cells taking their place. When teeth are chewing or in contact with each other they generate force that travels through the tooth roots to the bone and stimulates cell growth at a healthy replacement rate.
But when a tooth is missing, so is this stimulation. This slows the replacement rate and eventually leads to decreased bone volume. Too much bone loss could create obstacles for orthodontic treatment or a future dental implant.
To avoid this, the dentist will often place a bone graft with processed bone mineral within the empty tooth socket right after extraction. The graft serves as a scaffold for bone cells to grow upon. The graft (plus any other added growth boosters) can help maintain a healthy level of bone volume to facilitate future orthodontic or restorative treatments.
Since targeted extraction for orthodontics is time-sensitive, you should have your child's bite evaluated by an orthodontist by age 7 to see if any action is necessary. The earlier a malocclusion is detected, the more likely a more attractive and healthy smile will be the ultimate outcome.
