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.
Even though coronavirus lockdowns have prevented TV hosts from taping live shows, they're still giving us something to watch via virtual interviews. In the process, we're given occasional glimpses into their home life. During a Tonight Show interview with Seahawks quarterback Russell Wilson and his wife, R & B performer Ciara, Jimmy Fallon's daughter Winnie interrupted with breaking news: She had just lost a tooth.
It was an exciting and endearing moment, as well as good television. But with 70 million American kids under 18, each with about 20 primary teeth to lose, it's not an uncommon experience. Nevertheless, it's still good to be prepared if your six-year-old is on the verge of losing that first tooth.
Primary teeth may be smaller than their successors, but they're not inconsequential. Besides providing young children with the means to chew solid food and develop speech skills, primary teeth also serve as placeholders for the corresponding permanent teeth as they develop deep in the gums. That's why it's optimal for baby teeth to remain intact until they're ready to come out.
When that time comes, the tooth's roots will begin to dissolve and the tooth will gradually loosen in the socket. Looseness, though, doesn't automatically signal a baby tooth's imminent end. But come out it will, so be patient.
Then again, if your child, dreaming of a few coins from the tooth fairy, is antsy to move things along, you might feel tempted to use some old folk method for dispatching the tooth—like attaching the tooth to a door handle with string and slamming the door, or maybe using a pair of pliers (yikes!). One young fellow in an online video tied his tooth to a football with a string and let it fly with a forward pass.
Here's some advice from your dentist: Don't. Trying to pull a tooth whose root hasn't sufficiently dissolved could damage your child's gum tissues and increase the risk of infection. It could also cause needless pain.
Left alone, the tooth will normally fall out on its own. If you think, though, that it's truly on the verge (meaning it moves quite freely in the socket), you can pinch the tooth between your thumb and middle finger with a clean tissue and give it a gentle tug. If it's ready, it should pop out. If it doesn't, leave it be for another day or two before trying again.
Your child losing a tooth is an exciting moment, even if it isn't being broadcast on national television. It will be more enjoyable for everyone if you let that moment come naturally.

Despite momentous strides in recent years in the fight against cancer, treatments can still disrupt normal life. Both radiation and chemotherapy have side effects that can cause problems in other areas of health—particularly the teeth and gums.
If you or a loved one are undergoing cancer treatment, it's important to get ahead of any potential side effects it may have on dental health. Here are 4 things that can help protect teeth and gums while undergoing cancer treatment.
Get a preliminary dental exam. Before beginning treatment, patients should have their dentist examine their teeth and gums to establish a baseline for current dental health and to treat any problems that may already exist. However, patients should only undergo dental procedures in which the recovery time can be completed before starting radiation or chemotherapy.
Be meticulous about oral hygiene. Undergoing cancer treatment can increase the risks for developing tooth decay or gum disease. That's why it's important that patients thoroughly brush and floss everyday to reduce bacterial plaque buildup that causes disease. Patients should also reduce sugar in their diets, a prime food source for bacteria, and eat “teeth-friendly” foods filled with minerals like calcium and phosphorous to keep teeth strong.
Keep up regular dental visits. The physical toll that results from cancer treatment often makes it difficult to carry on routine activities. Even so, patients should try to keep up regular dental visits during their treatment. Besides the extra disease prevention offered by dental cleanings, the dentist can also monitor for any changes in oral health and provide treatment if appropriate.
Minimize dry mouth. Undergoing cancer treatment can interfere with saliva production and flow. This can lead to chronic dry mouth and, without the full protection of saliva against dental disease, could increase the risk of tooth decay or gum disease. Patients can minimize dry mouth by drinking more water, using saliva boosters and discussing medication alternatives with their doctor.
It may not be possible to fully avoid harm to your oral health during cancer treatment, and some form of dental restoration may be necessary later. But following these guidelines could minimize the damage and make it easier to regain your dental health afterward.

Infancy is perhaps the only time in a person's life where a smile with just a few tiny teeth is still endearing. More will come—and then each will gradually depart, succeeded by permanent replacements.
That short lifespan, though, doesn't diminish their importance. Primary teeth not only provide children the ability to eat solid food and develop speech, but they set the stage for future dental health.
The latter arises from primary teeth's role as placeholders for incoming permanent teeth. Because permanent teeth eruption occurs in stages, primary teeth prevent earlier erupted teeth from drifting into the space intended for a later tooth. If they're lost prematurely and other teeth crowd into the space, the intended tooth may not have enough room to erupt properly, cascading from there into a poor bite (malocclusion).
The most common reason for premature loss is an aggressive form of tooth decay in children under 6 called early childhood caries (ECC). About one in four U.S. children encounter ECC, with those in poverty at higher risk. Infection in one tooth can spread to others, including newly erupted permanent teeth.
The goal then is to prevent ECC as much as possible, and initiate prompt treatment should it still occur. A good prevention strategy has two prongs: the actions and habits of parents or caregivers; and the prevention and treatment measures taken by dental providers.
At home, it's important that you wipe your newborn's gums with a clean, damp cloth after each feeding to reduce bacterial growth. As teeth erupt, switch then to gentle brushing with a rice grain-sized amount of baby toothpaste. You should also limit their sugar consumption, including not allowing them to sleep with a bedtime bottle of any liquid other than water.
It's also important that you start your child's regular dental visits around their first birthday. This allows us to detect any developing cavities, as well as apply sealants and topical fluoride to help prevent decay. And should a cavity develop, regular visits help ensure prompt treatment to preserve the tooth.
Your child's set of primary teeth only last a few short years, but their contribution echoes for a lifetime. Taking these measures to protect them from tooth decay ensures they'll fully make that contribution.

The top cause for adult tooth loss isn't decay or trauma—it's periodontal (gum) disease. The disease may begin with the gums, but it can ultimately damage underlying bone enough to weaken its support of teeth, causing them to loosen and fall out.
But that's not the end of the havoc gum disease can wreak. The consequences of an uncontrolled infection can ripple beyond the mouth and worsen other health problems like diabetes, heart disease or arthritis.
The common link between gum disease and these other conditions is the inflammatory response, a natural mechanism to fight infection caused by disease or trauma. This mechanism changes blood vessels to increase blood flow to hasten the travel of protective white blood cells to the injury or disease location.
But if this mechanism that supports healing becomes chronic, it can actually do harm. The chronic inflammation that occurs with gum disease can damage mouth structures, just as inflammation from diabetes or arthritis can damage other parts of the body. And any form of chronic inflammation, even that found in gum disease, can worsen other inflammatory diseases.
You can lessen this link between gum disease and other conditions—as well as improve your oral health—by preventing or seeking prompt treatment for any periodontal infection in the following ways:
- Practice daily brushing and flossing to clear away bacterial dental plaque, the main cause of gum disease;
- See your dentist regularly for more thorough dental cleanings and checkups;
- See your dentist promptly if you notice red, swollen or bleeding gums, common signs of a gum infection;
- Stop smoking to lower your risk for both gum disease and tooth decay;
- Adopt a healthy diet, which can help you lose weight (a factor in diabetes and other inflammatory diseases) and strengthen your immune system;
- Manage other inflammatory conditions to lessen their effect on your gum disease risk.
Taking these steps can help you avoid the inflammation caused by gum disease that might also affect the rest your body. Seeking prompt treatment at the first sign of an infection will also minimize the damage to your teeth and gums and the effect it could have on the rest of your health.
