Dental amalgam—also known as “silver fillings”—has been used for nearly a hundred years to treat cavities. There are several reasons why this mixture of metals has been the go-to material among dentists: Malleable when first applied, dental amalgam sets up into a durable dental filling that can take years of biting forces. What’s more, it’s stable and compatible with living tissue.
But there’s been growing concern in recent years about the safety of dental amalgam, with even some wondering if they should have existing fillings replaced. The reason: liquid mercury.
Mercury makes up a good portion of dental amalgam’s base mixture, to which other metals like silver, tin or copper are added to it in powder form. This forms a putty that can be easily worked into a prepared cavity. And despite the heightened awareness of the metal’s toxicity to humans, it’s still used in dental amalgam.
The reason why is that there are various forms of mercury and not all are toxic. The form making headlines is known as methylmercury, a compound created when mercury from the environment fuses with organic molecules. The compound builds up in the living tissues of animals, particularly large ocean fish, which have accumulated high concentrations passed up through their food chain.
That’s not what’s used in dental amalgam. Dentists instead use a non-toxic, elemental form of mercury that when set up becomes locked within the amalgam and cannot leach out. Based on various studies, treating cavities with it poses no health risks to humans.
This also means there’s no medical reason for having an existing silver fillings removed. Doing so, though, could cause more harm than good because it could further weaken the remaining tooth structure.
The most viable reason for not getting a dental amalgam filling is cosmetic: The metallic appearance of amalgam could detract from your smile. There are newer, more life-like filling options available. Your dentist, though, may still recommend dental amalgam for its strength and compatibility, especially for back teeth. It’s entirely safe to accept this recommendation.
While not as prevalent as adults, teenagers can have missing teeth, usually from injury or from never having been formed. Fortunately, life-like dental implants can replace missing teeth. But unfortunately for teens, implants aren't usually a good option—yet.
That's because a teenager's jaws are still growing, and will continue until early adulthood. Dental implants don't adjust to this growth like natural teeth and will eventually look out of place. It's best, then, to consider a temporary restoration for a teenager. And, there are two excellent options: one removable and one fixed.
The first is a removable partial denture (RPD). Like a full denture, an RPD has an acrylic base that resembles gum tissue, to which prosthetic (false) teeth are attached to match the positions of the missing teeth. It's usually held in place with metal or nylon clips that slide under part of the natural teeth at the gum line.
RPDs are versatile and durable. But they're not designed to be worn indefinitely, so they can be damaged if subjected to excessive biting forces like biting into something hard. And, peer-pressured teens may also feel self-consciousness about wearing a “denture.”
The other option is a bonded bridge. It's similar to a traditional bridge, except how it's supported in the mouth. A traditional bridge gains its support from the crowns on each end attached to natural teeth, which must be permanently altered for them. By contrast, a bonded bridge has strips of dental material extending from both sides of its back that are bonded to the back of the adjacent natural teeth.
With the bonding material behind the bridge, it can't be seen—and the natural teeth won't require permanent alteration. But a bonded bridge is usually more costly than an RPD and less secure than a traditional bridge. And not every teen is a viable candidate for one: issues like how the teeth fit together and if the teen has a tooth grinding habit could be strikes against this fixed option.
Your dentist can help you sort out the best of these options for your teen. If cared for and maintained properly, either restoration can buy you time until your teen is ready for dental implants.

Whether she’s singing, dancing or acting, Jennifer Lopez is a performer who is known for giving it all she’s got. But during one show, Lopez recently admitted, she gave a bit more then she had planned.
“I chipped my tooth on stage,” she told interviewers from Entertainment Tonight, “and had to finish the show….I went back thinking ‘Can I finish the show like this?’”
With that unlucky break, J-Lo joins a growing list of superstar singers—including Taylor Swift and Michael Buble—who have something in common: All have chipped their teeth on microphones while giving a performance.
But it’s not just celebs who have accidental dental trouble. Chips are among the most common dental injuries—and the front teeth, due to their position, are particularly susceptible. Unfortunately, they are also the most visible. But there are also a number of good ways to repair chipped, cracked or broken teeth short of replacing them.
For minor to moderate chips, cosmetic bonding might be recommended. In this method, special high-tech resins, in shades that match your natural teeth, are applied to the tooth’s surface. Layers of resin, cured with a special light, will often restore the tooth to good appearance. Best of all, the whole process can often be done in just one visit to the dental office, and the results can last for several years.
For a more permanent repair—or if the damage is more extensive—dental veneers may be another option. Veneers are wafer-thin shells that cover the entire front surface of one or more teeth. Strong, durable and natural-looking, they can be used to repair moderate chips, cracks or irregularities. They can also help you get a “red-carpet” smile: brilliant white teeth with perfectly even spacing. That’s why veneers are so popular among Hollywood celebs—even those who haven’t chipped their teeth!
Fortunately, even if the tooth is extensively damaged, it’s usually possible to restore it with a crown (cap), a bridge—or a dental implant, today’s gold standard for whole-tooth replacement. But in many cases, a less complex type of restoration will do the trick.
Which tooth restoration method did J-Lo choose? She didn’t say—but luckily for her adoring fans, after the microphone mishap she went right back up on stage and finished the show.

Although adults are more prone to dental disease, children aren't immune from one particular infection, tooth decay. Some children, in fact, are at higher risk for an aggressive form called early childhood caries (ECC).
There are a number of things you can do to help your child avoid this destructive disease, especially daily brushing and flossing to remove bacterial dental plaque, the underlying cause for tooth decay. It's also important for your child to see a dentist regularly for professional dental cleanings and checkups.
But some of their teeth, particularly the back molars, may need some extra attention to fully protect them against decay. This is because larger teeth like molars have numerous pits and crevices along their biting surfaces that can accumulate dental plaque difficult to remove by brushing alone. The added plaque increases the presence of bacteria around the tooth, which increases the risk of decay.
To minimize this possibility, dentists can apply a dental sealant to "smooth out" those pits and crevices in the molars and make it more difficult for plaque to accumulate. This is a quick and painless procedure in which a dentist brushes a liquid plastic resin or similar material onto the teeth's biting surfaces. They then apply a curing light to harden it into a durable coating.
About one-third of children—mostly those considered at higher risk for tooth decay—have undergone sealant treatment. But the American Dental Association and the American Academy of Pediatric Dentistry recommend this preventive measure for all children between ages 5 and 7, and then later between 11 and 14 when additional molars come in. Although there is a moderate cost per tooth for sealant application, it's much less than the potential expense of treating an infected tooth.
Combined with daily oral hygiene and other preventive measures, sealants can reduce the chances of damaging tooth decay. Keeping your child's teeth healthy is an important part in maintaining their dental health today—and tomorrow.
Dental implants are all the rage—and for good reason: They’re incredibly “tooth-like,” both in appearance and function. They also have a stunningly high success rate: More than 95% of implants still function after ten years. This means out of thousands of implants installed each year, only a handful fail.
But although that’s an amazingly low number, they’re still failures for real people who’ve suffered a loss. If you’re considering dental implants the chances of that being your experience are quite low. But it could still happen.
Here’s a few things you can do to make sure your implants don’t fail.
Stop smoking. Of the small percentage of implant failures, an inordinate number are smokers. A smoker’s chances of implant failure are roughly double those of non-smokers. Smoking, and to some degree any tobacco use, can make your mouth an unhealthier place: Not only can it increase your dental disease risk, but it can interfere with the healing process after implant placement and increase the chances of early failure.
Manage your health. Diabetes and similar systemic conditions can interfere with the healing process too, which could impact your implant attachment to bone. Diabetics thus run a slight risk of implant failure—but actual failures mostly involve patients who don’t have good control of their symptoms. If you’re a diabetic, properly managing your condition will lower your risk of implant failure to nearly identical that of someone without diabetes.
Treat gum disease. Implants in themselves are immune to disease—but the underlying bone that supports them isn’t. A gum disease infection could eventually weaken and diminish the implant-bone attachment. If this happens around an implant, its stability can be severely compromised. The best strategy is to prevent gum disease through daily, thorough brushing and flossing to remove disease-causing dental plaque. And if you see any symptoms like gum swelling, redness or bleeding, see your dentist as soon as possible.
Your implants could serve you well for decades. Just be sure you’re doing the right things to ensure their longevity.
