For over half a century now, community water systems have been adding fluoride to drinking water to help reduce the risk of tooth decay. Numerous long-term studies have demonstrated the soundness of this practice, prompting the U.S. Centers for Disease Control to call water fluoridation one of the ten most effective public health measures of the 20th Century.
In the 1960s, after years of study into the teeth-strengthening effects of fluoride, the U.S. Public Health Service recommended that drinking water utilities add fluoride at a rate of between 0.7 and 1.20 milligrams per liter (mg/L) or parts per million (ppm) of water. This recommendation held fast until 2015 when the service changed the recommendation to no more than 0.7 mg/L.
Why the change to guidelines that had been in place for over fifty years? The revision was in response to an increasing occurrence of dental fluorosis. This condition happens when the teeth absorb more fluoride than necessary, leading to discoloration of the surface enamel, creating effects like small white spots or brownish “mottling.”
Dental fluorosis is the only known health condition caused by fluoride. As such, it doesn't damage the tooth itself, and is mainly a cosmetic problem. But it can still be avoided if fluoride intake is kept at moderate levels.
The original recommendation was sound science when first introduced. Since then, though, the prevalence of fluoride in everyday life has grown, with the chemical commonly found in dental care products like toothpastes or mouthrinses, as well as many processed foods and beverages and even infant formula. Our society's overall intake of fluoride has been growing as a result.
The new recommendation came after several years of research to verify water fluoridation levels of 0.7 mg/L would still be effective in the fight against tooth decay while lowering the risk of dental fluorosis. With this adjustment, this important and safe measure for keeping your family's teeth protected against disease is safer than ever.
Although they can be expensive upfront, dental implants often prove to be a wise investment in the long-term. With a success rate that outperforms other teeth replacement restorations, dental implants could be the answer to a more attractive smile that could last for decades.
But while their success rate is high (95% still functioning after ten years), they can and do occasionally fail. Of those that do, two-thirds happen in patients who smoke.
This unfortunate situation stems from smoking's overall effect on dental health. The nicotine in tobacco constricts oral blood vessels, inhibiting the flow of nutrients and antibodies to the teeth and gums. Inhaled smoke can scald the inside skin of the mouth, thickening its surface layers and damaging salivary glands leading to dry mouth.
These and other effects increase the risk for tooth decay or gum disease, which in turn makes it more likely that a smoker will lose teeth than a non-smoker and require a restoration like dental implants. And blood flow restriction caused by nicotine in turn can complicate the implant process.
Long-term implant durability depends on bone growth around the imbedded implant in the ensuing weeks after implant surgery. Because of their affinity with the titanium used in implants, bone cells readily grow and adhere to the implant. This integration process anchors the implant securely in place. But because of restricted blood flow, the healing process involved in bone integration can be impaired in smokers. Less integration may result in less stability for the implant and its long-term durability.
To increase your chances of a successful implant installation, you should consider quitting smoking and other tobacco products altogether before implant surgery. If that's too difficult, then cease from smoking for at least one week before surgery and two weeks after to better your odds of implant success. And be as meticulous as possible with daily brushing and flossing, as well as regular dental visits, to reduce your risk of disease.
There are many good reasons to quit smoking. If nothing else, do it to improve your dental health.

During the COVID-19 quarantines, stir-crazy celebrities have been creating some “unique” home videos—like Madonna singing about fried fish to the tune of “Vogue” in her bathroom or Cardi B busting through a human-sized Jenga tower. But an entertaining Instagram video from Kevin Bacon also came with a handy culinary tip: The just-awakened film and TV actor showed fans his morning technique for cutting a mango to avoid the stringy pulp that gets between your teeth. After cutting a mango in half, he scored it lengthwise and crosswise to create squares and then turned the mango inside out for easy eating.
With his mango-slicing video garnering over a quarter-million views, the City on a Hill star may have touched a nerve—the near universal annoyance we all have with food stuck between our teeth. Trapped food particles aren't only annoying, they can also contribute to a bacterial film called dental plaque that's the top cause for tooth decay and gum disease.
Unfortunately, it's nearly impossible to avoid stuck food if you love things like popcorn, poppy-seed muffins or barbecue ribs. It's helpful then to have a few go-to ways for removing food caught between teeth. First, though, let's talk about what NOT to use to loosen a piece of stuck food.
A recent survey of more than 1,000 adults found that when removing something caught between our teeth, we humans are a creative lot. The makeshift tools that survey respondents said they've used in a pinch included twigs, safety pins, screwdrivers and nails (both the hammer and finger/toe variety). Although clever, many such items are both unsanitary and harmful to your gums and tooth enamel, especially if they're metallic or abrasive.
If you want a safe way to remove unwanted food debris, try these methods instead:
Brush your teeth: The gentle abrasives in toothpaste plus the mechanical action of brushing can help dislodge trapped food.
Use dental floss: A little bit of dental floss usually does the trick to remove wedged-in food—and it's easy to carry a small floss container or a floss pick on you for emergencies.
Try a toothpick. A toothpick is also an appropriate food-removing tool, according the American Dental Association, as long as it is rounded and made of wood.
See your dentist. We have the tools to safely and effectively remove trapped food debris that you haven't been able to dislodge by other means—so before you get desperate, give us a call.
You can also minimize plaque buildup from food particles between teeth by both brushing and flossing every day. And for optimally clean teeth, be sure you have regular dental office cleanings at least twice a year.
Thanks to Kevin Bacon's little trick, you can have your “non-stringy” mango and eat it too. Still, you can't always avoid food getting wedged between your teeth, so be prepared.
