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.
There have been vast improvements over the years in various methods to restore diseased, damaged or missing teeth. A lot of this is due to better restorative materials that are stronger and more life-like.
But given the mouth's hostile environment and the forces generated from chewing, even the most durable restorations could fail. You can, however, improve their durability through proper care and good protective practices.
Here are 3 ways to preserve your dental work and keep it functioning for years or even decades to come.
Daily oral hygiene. Although the bacteria in dental plaque doesn't affect non-living dental materials, it can infect and weaken living tissues around fillings, crowns or implants. Because these tissues often support restorations, an infection could cripple your dental work's survivability. You can prevent this by practicing daily brushing and flossing, and getting regular dental cleanings, to remove plaque and decrease your risk of dental disease.
Dietary choices. You can further prevent dental disease by restricting your consumption of sugar and eating foods rich in calcium and other nutrients. But there's one other thing to keep in mind about what you eat: Some foods can stain veneers and other restorations, as well as natural tooth enamel. If staining occurs at different rates, your dental work could stand out from your natural teeth and look out of place. You can help avoid this by limiting items in your diet known to stain (like wine or coffee) and practicing good oral hygiene.
Poor habits. Many of us have nervous habits like nail-biting or ice-chewing, or an unconscious habit of grinding teeth. Habits like these can damage restorations like composite bonding or veneers. To prevent the chances of this happening, take steps to stop habits and practices that involve biting down on hard objects (including foods like fruits with hard skins). You should also talk to your dentist about solutions to reduce teeth grinding, especially if it's occurring while you sleep.
Above all, keep up your dental visits to regularly monitor the condition of your dental work and obtain repairs or enhancements as needed. By taking care of these valuable restorations, you can help them continue to function and serve your needs for a long time to come.

Ever have a paper cut or an irritated hangnail? They're not considered major health problems, but, boy, can they sting!
Something similar can occur in the corners of your mouth called angular cheilitis. It's also known as perleche, from the French word “to lick” (a common habit with this type of sore). It can occur at any age, with children or young adults developing it from drooling during sleep or orthodontic treatment.
Older adults, though, are more prone than younger people for a variety of reasons. Age-related wrinkling is a major factor, especially “marionette lines” that run from the mouth to the chin. Dried or thinned out skin due to exposure from cold, windy weather may also contribute to perleche.
Perleche can also develop from within the mouth, particularly if a person is experiencing restricted salivary flow leading to reduced lubrication around the lips. Poorly cleaned dentures, weakened facial supporting structure due to missing teeth, vitamin deficiencies and some systemic diseases can all lead to perleche. And if an oral yeast infection occurs around the cracked mouth corners, the irritation can worsen and prolong the healing process.
To clear up a case of cracked mouth corners, you should promptly see your dentist for treatment. Treatment will typically include some form of antifungal ointment or lozenge applied over a few days to clear up the sores and prevent or stop any infection. You might also need to apply a steroid ointment for inflammation and other ointments to facilitate healing.
To prevent future episodes, your dentist may ask you to use a chlorhexidine mouthrinse to curb yeast growth. If you wear dentures, you'll need to adopt a regular cleaning routine (as well as leaving them out at night). You might also wish to consider updated dental restorations or orthodontics to improve dental support, and help from a dermatologist if wrinkling might be a potential cause.
Cracked mouth corners won't harm you, but they can make for a miserable experience. Take steps to relieve the irritation and any future occurrence.
