Fluoride is a critical weapon in the war against tooth decay. But this natural chemical proven to strengthen tooth enamel has also aroused suspicion over the years that it might cause health problems.
These suspicions have led to rigorous testing of fluoride's safety. And the verdict from decades of research? We've found only one verifiable side effect, a condition called enamel fluorosis. Caused by too much fluoride present in the body, enamel fluorosis produces white streaks and patches on teeth, and can develop into darker staining and pitting in extreme cases. But other than having an unattractive appearance, the teeth remain sound and healthy.
Fortunately, you can reduce the risk of fluorosis by limiting fluoride exposure to within recommended limits. Fluoride can show up in processed foods and other substances, but the two sources you should focus on most are oral hygiene products and fluoridated drinking water.
Dentists highly recommend using toothpaste with fluoride to fight tooth decay. But be careful how much your family uses, especially younger members. An infant only needs a slight smear of toothpaste on their brush for effective hygiene. At around age 2, you can increase the amount to about the size of a vegetable pea.
As to drinking water, most utilities add fluoride to their supply. If yours does, you can find out how much they add by calling them or visiting cdc.gov ("My Water's Fluoride"), where you can also learn more about recommended levels of fluoridation. If you think it's excessive, you can switch to water labeled "de-ionized," "purified," "demineralized," or "distilled," which contain little to no added fluoride.
Even if your fluoridated water is within recommended levels, you may wish to take extra precautions for infants nursing with formula. If possible, use "ready-to-feed" formula, which usually contains very low amounts of fluoride if any. If you're using the powdered form, use only water with the aforementioned labeling for mixing.
Before making any drastic changes that might affect your family's fluoride intake, consult with your dentist first. And be sure you're keeping up regular dental visits—your dentist may be able to detect any early signs of fluorosis before it becomes a bigger problem.

Tooth loss is a problem that affects many seniors—and since May is Older Americans Month, this is a good time to talk about it. Did you know that more than a quarter of adults over age 75 have lost all of their natural teeth? This not only affects their quality of life but poses a significant health risk.
According to a study in The Journal of Prosthodontics, significant tooth loss is associated with increased risk for malnutrition—and also for obesity. If this seems like a contradiction, consider that when you have few or no teeth, it’s much easier to eat soft, starchy foods of little nutritional value than it is to eat nutritious fresh fruits and vegetables. If all of your teeth are missing, it’s especially critical to replace them as soon as possible.
There are several ways to replace a full set of missing teeth, including removable dentures, overdentures, and fixed dentures:
Removable dentures are the classic replacement teeth that you put in during the day and take out at night. (However, if you suffer from sleep apnea, research has found that keeping dentures in at night may help keep the airway open, so if you have this condition, be sure to mention it to your doctor and dentist it). Dentures have come a long way in terms of how convincing they look, but they still have some disadvantages: For one thing, they take some getting used to—particularly while eating. Also, wearing removable dentures can slowly wear away the bone that they rest on. As that bone gradually shrinks over time, the dentures cease to fit well and require periodic adjustment (re-lining) or a remake.
Overdentures are removable dentures that attach onto a few strategically placed dental implants, which are small titanium posts placed in the bone beneath your gums. Strong and secure, implants prevent the denture from slipping when you wear it. Implants also slow the rate of bone loss mentioned above, which should allow the denture to fit better over a longer period of time. The ability to maintain hygiene is easier because you can remove them for cleaning.
Fixed implant-supported dentures are designed to stay in your mouth all the time, and are the closest thing to having your natural teeth back. An entire row of fixed (non-removable) replacement teeth can usually be held in place by 4-6 dental implants. Dental implant surgery is an in-office procedure performed with the type of anesthesia that’s right for you. After implants have been placed and have integrated with your jaw bone—generally after a few months—you can enjoy all of your favorite foods again without worry or embarrassment.

Losing teeth continues to be an all too common experience for people, especially those in their senior years. Fortunately, there are several ways to replace them, ranging from partial or full dentures to implants.
Some, though, postpone or simply choose not to replace a lost tooth, often because of the cost. But putting off a dental restoration could have a long-term impact on your health, and not in a good way. Continuing bone deterioration is one of the top consequences of delayed restoration.
Like other bones in the body, the jawbone is living tissue with cells that form, grow and eventually wear out. At the end of their life, these older cells give way to new cells. Eating and chewing play an important role in maintaining this growth cycle: the forces we generate as we chew travel up through the tooth roots to stimulate bone growth in the jaw.
When a tooth goes missing, though, the stimulus ends. Over time the bone cell replacement rate can fall off and the bone slowly loses volume. To make matters worse, bone loss can continue beyond the immediate bone underlying the tooth and affect the rest of the jawbone. The jaw can shrink in height and width, and in time become weaker overall and more susceptible to fracture.
But dental implant restorations in particular could help stop or even reverse bone deterioration at the site of the missing teeth. The titanium post implanted in the jaw attracts bone cells, which grow and adhere to its surface. Over time the bone fills in and becomes stronger.
You don't want to wait too long, though, because implants depend on a minimum amount of bone present for secure placement. You should therefore undergo an implant restoration as soon as it's practical after tooth loss. Otherwise, although we may be able to restore some of the lost bone with bone grafting, you may need to consider another restorative option.
When it comes to replacing missing teeth, time isn't on your side. But the right kind of dental restoration undertaken promptly can make for a brighter, healthier future.

On the big screen, Australian-born actress Margot Robbie may be best known for playing devil-may-care anti-heroes—like Suicide Squad member Harley Quinn and notorious figure skater Tonya Harding. But recently, a discussion of her role in Peter Rabbit proved that in real life, she’s making healthier choices. When asked whether it was hard to voice a character with a speech impediment, she revealed that she wears retainers in her mouth at night, which gives her a noticeable lisp.
“I actually have two retainers,” she explained, “one for my bottom teeth which is for grinding my teeth, and one for my top teeth which is just so my teeth don't move.”
Clearly Robbie is serious about protecting her dazzling smile. And she has good reasons for wearing both of those retainers. So first, let’s talk about retainers for teeth grinding.
Also called bruxism, teeth grinding affects around 10 percent of adults at one time or another, and is often associated with stress. If you wake up with headaches, sore teeth or irritated gums, or your sleeping partner complains of grinding noises at night, you may be suffering from nighttime teeth grinding without even being aware of it.
A type of retainer called an occlusal guard is frequently recommended to alleviate the symptoms of bruxism. Typically made of plastic, this appliance fits comfortably over your teeth and prevents them from being damaged when they rub against each other. In combination with stress reduction techniques and other conservative treatments, it’s often the best way to manage teeth grinding.
Orthodontic retainers are also well-established treatment devices. While appliances like braces or aligners cause teeth to move into better positions, retainers are designed to keep teeth from moving—helping them to stay in those positions. After active orthodontic treatment, a period of retention is needed to allow the bite to stabilize. Otherwise, the teeth can drift right back to their old locations, undoing the time and effort of orthodontic treatment.
So Robbie has the right idea there too. However, for those who don’t relish the idea of wearing a plastic appliance, it’s often possible to bond a wire retainer to the back surfaces of the teeth, where it’s invisible. No matter which kind you choose, wearing a retainer can help keep your smile looking great for many years to come.

Wearing braces will probably never make your list of Most Pleasurable Life Experiences: you'll have to avoid certain foods and habits, endure some occasional discomfort, and perhaps feel some embarrassment about your appearance. The good news, though, is that at worst, these are mostly no more than inconveniences and additionally they're well worth the straighter, more attractive smile you'll achieve.
But there's one downside to braces that can lead to something more serious. The braces hardware makes brushing and flossing more difficult—and that could increase your risk of dental disease.
The principal goal of oral hygiene is to remove dental plaque, a thin film of accumulated bacteria and food particles that can cause tooth decay or periodontal (gum) disease. Without effective brushing and flossing, plaque can build up quickly and make the chances of having either of these two diseases more likely.
Not only does the braces hardware hinder your toothbrush's or floss's access to the parts of the teeth it covers, but it can also create "hiding places" for plaque build-up. Several studies have found that braces wearers on average have up to two to three times the plaque build-up of non-braces wearers.
There are ways, though, to make hygiene easier while wearing braces, particularly with flossing. Floss threaders or interproximal brushes can both be used to access between teeth while wearing braces. Another option is a water flosser or irrigator that sprays pressurized water between teeth (and beneath brackets and wires) to remove plaque. And braces wearers can get a prevention boost with topical fluoride applications or antibacterial mouth rinses to reduce disease-causing bacteria.
Besides taking a little extra time with brushing and flossing, you can also boost your mouth's health with good nutrition choices, less sugar consumption and keeping up regular dental visits. And, you should also see your dentist promptly if you notice any signs of tooth or gum problems—the sooner you have it checked and treated, the less damage any dental disease is likely to cause.
It's not easy keeping your teeth and gums plaque-free while wearing braces. But with a little extra time and effort, a few helpful tools and your dentist's support, you can maintain a healthy mouth during orthodontic treatment.
