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.
If you're one of the millions of people wearing an oral appliance, you already know how important it is to your dental health. Whatever the purpose—replacing teeth, stopping teeth grinding or guarding against injury—you want to get the most and longest service from it. That means showing your appliance some tender loving care on a regular basis.
It doesn't require a lot of time and effort to clean and maintain your oral appliance. But there are some pitfalls that could lead to greater wear and tear and just outright damage. Here are 3 things you should be on the alert for to keep your appliance doing its job for you.
Be careful how you clean it. Your appliance might resemble natural oral tissue, but it's not—so don't use toothpaste. Toothpaste contains abrasives, which are fine for tooth enamel but damaging to materials in your appliance. Instead, use dish detergent, hand soap or a specialized cleaner. Don't use hot or boiling water, which could soften any plastic and distort the appliance's mouth fit. Nix the bleach too, which can fade colored portions of the appliance that mimic gum tissue.
Don't wear them 24/7 unless your dentist advises. Depending on the type and function of your appliance, you shouldn't wear them around the clock unless your dentist advises otherwise. Dentures are usually removed at night while you sleep to help prevent bacterial growth. Keeping them out at night -and keeping them clean—will help lower your risk of dental disease. One caveat, though: there are some concerns today about the effect of keeping dentures out of the mouth at night on sleep apnea. It's a good idea, then, to discuss the issue with your dentist regarding taking dentures out at night.
Prevent accidental drops on hard surfaces. Chewing forces are considerable, but your appliance is designed to take it. The same can't be said, though, if they accidentally fall on a hard surface—the fall could crack or break them. To protect against this, be sure to put a soft towel or cloth in your sink basin while you're cleaning your appliance. And don't place it on a night stand or low surface where it could be knocked off accidentally by a child, a pet or you. A sudden accident like this could be costly.

How a dental crown from your dentist in Virginia Beach, Virginia can help your smile.
If you have badly damaged teeth which are reducing your ability to chew, you may need a dental crown. Dr. Jason Campbell at Seaside Dentistry in Virginia Beach, Virginia offers dental crowns to help your smile. He proudly serves residents of Virginia Beach, Landstown, and Princess Anne, Virginia and he can help you too.
Dental crowns can give you a much stronger smile. That’s because a dental crown covers the entire visible part of your tooth above the gumline. Dental crowns protect your teeth from breaking by evenly distributing the pressure and stress when you bite down or chew.
Consider dental crowns if you have teeth that are:
- Fractured or broken from trauma
- Severely damaged from decay
- Eroded or chipped from grinding, clenching, or aging
Dental crowns can also give you a much more beautiful smile. That’s because today’s dental crowns are made from porcelain, a sparkling, light-reflective material that closely resembles tooth structure. In fact, when a porcelain crown is placed, it is virtually indistinguishable from a natural tooth. Porcelain is also stain-resistant, so your porcelain crowns will stay sparkling for years.
A full porcelain crown is one of the most aesthetically beautiful crowns, but sometimes you need extra strength. For back teeth, where you need extra strength for chewing, consider a porcelain-fused-to-metal crown, known as a PFM crown. These crowns combine the beauty of porcelain with the strength of a metal underlay.
To find out more about how dental crowns can benefit your smile, and the different types of dental crowns, talk with an expert. Call Dr. Jason Campbell at Seaside Dentistry in Virginia Beach, Virginia today.
You feel great about your new smile, thanks to dental implants! And you may also be feeling relief as the problems with your former teeth fade into the past.
But that doesn’t mean you can drop your guard on periodontal (gum) disease. Even though implants are impervious to decay, the natural tissues supporting them are vulnerable to periodontal (gum) disease. If they become diseased, your implants could lose their bone support and eventually fail.
And that failure could happen quickly. That’s because, as life-like as they are, implants don’t have one important advantage of real teeth: an attachment to a connective tissue called the periodontal ligament. This tough but elastic ligament lies between the teeth and the bone, attaching to both with tiny extending fibers and holding the teeth in place.
And that’s not all: Because the periodontal ligament contains an abundance of blood vessels, it can supply antibodies to help fight infection. The body’s defenses may not be able to stop disease, but they can certainly inhibit its progress.
Implants can’t benefit from this infection-fighting mechanism. So, when an infection arises in the gums surrounding an implant, it can spread rapidly through a form of gum disease known as peri-implantitis (literally “inflammation around an implant”). If we don’t stop it with prompt treatment, you could lose bone support from your implant and eventually lose it, sometimes in quick fashion.
That’s why you should clean your implants everyday like you do the rest of your teeth with brushing and flossing. You should also visit us regularly for dental cleanings. A dental cleaning involving implants is similar to one with natural teeth, except the hygienist won’t use metal instruments on the implants—this could create tiny scratches on their surface. Instead, they’ll use nylon or plastic instruments or ultrasonic equipment to clean them.
You should also make a dental appointment as soon as you notice swollen, reddened or bleeding gums. If you have gum disease, we can stop the infection through treatment and restore your gums to health. This can be a long and involved process, but it’s necessary to preserve your implants.
It’s true that implants can change your life. If you want to enjoy that change for a long time, take care of your implants and the natural tissues that support them.

Everyone loves a concert where there's plenty of audience participation… until it starts to get out of hand.Â Recently, the platinum-selling band Fifth Harmony was playing to a packed house in Atlanta when things went awry for vocalist Camila Cabello. Fans were batting around a big plastic ball, and one unfortunate swing sent the ball hurtling toward the stage — and directly into Cabello's face. Pushing the microphone into her mouth, it left the “Worth It” singer with a chipped front tooth.
Ouch! Cabello finished the show nevertheless, and didn't seem too upset. “Atlanta… u wild… love u,” she tweeted later that night. “Gotta get it fixed now tho lol.” Fortunately, dentistry offers a number of ways to make that chipped tooth look as good as new.
A small chip at the edge of the tooth can sometimes be polished with dental instruments to remove the sharp edges. If it's a little bigger, a procedure called dental bonding may be recommended. Here, the missing part is filled in with a mixture of plastic resin and glass fillers, which are then cured (hardened) with a special light. The tooth-colored bonding material provides a tough, lifelike restoration that's hard to tell apart from your natural teeth. While bonding can be performed in just one office visit, the material can stain over time and may eventually need to be replaced.
Porcelain veneers are a more long-lasting solution. These wafer-thin coverings go over the entire front surface of the tooth, and can resolve a number of defects — including chips, discoloration, and even minor size or spacing irregularities. You can get a single veneer or have your whole smile redone, in shades ranging from a pearly luster to an ultra-bright white; that's why veneers are a favorite of Hollywood stars. Getting veneers is a procedure that takes several office visits, but the beautiful results can last for many years.
If a chip or crack extends into the inner part of a tooth, you'll probably need a crown (or cap) to restore the tooth's function and appearance. As long as the roots are healthy, the entire part of the tooth above the gum line can be replaced with a natural-looking restoration. You may also need a root canal to remove the damaged pulp material and prevent infection if the fracture went too far. While small chips or cracks aren't usually an emergency (unless accompanied by pain), damage to the tooth's pulp requires prompt attention.
