One of the top concerns in public health today is exposure to the metallic element mercury within the environment. At abnormal levels, mercury can have a toxic effect on our nervous systems and cause other health problems.
These concerns over mercury have also increased attention on one material in dentistry that has included the metal in its makeup for over a century — dental amalgam for filling teeth. Amalgam is a metal alloy that can include, in addition to mercury, silver, tin, and copper. When first mixed dental amalgam is a moldable material used for fillings in prepared teeth. It then hardens into a durable restoration that can withstand biting forces.
While the use of amalgam has declined with the introduction of life-like colored fillings, it's still used for teeth like molars subject to high biting forces. With what we now know about the ill effects of mercury (which can make up to half of an amalgam mixture) is it safe to continue its use?
The American Dental Association has performed extensive research into amalgam safety. They've found that mercury is stabilized by the other metals in the amalgam. This prevents "free" molecules of mercury, the real source of harm to health, from escaping into the blood stream in the form of vapor. Although trace amounts of mercury vapor from the amalgam are released as a person chews, those levels are well below the threshold that could cause harm.
From a patient standpoint, the biggest drawback to dental amalgam isn't safety — it's the appearance of teeth it's used on. Silver fillings aren't considered attractive. And now there are viable filling alternatives that not only look like natural teeth but can withstand biting forces almost as well as amalgam. These materials include composite resins, mixtures of glass or quartz within resin, or glass and resin ionomers. Each of these has advantages and disadvantages depending on how and where they're applied.
After a thorough dental examination, we'll be able to advise you on what filling material will work best to produce the best result. And if we do suggest dental amalgam you can rest assured it will be a safe choice.

It is only natural that, with continued use throughout your life, your teeth would dull, stain or become discolored. However, avoiding this natural progression of your teeth can be as easy as avoiding the things which stain them. Find out about keeping your teeth white and bright and helping restore their appearance with teeth whitening with Dr. Gregory Hysong and Dr. Lynda LePore at Colesville Dentistry in Silver Spring, MD.
What causes tooth discolorations and stains?
Stains occur on one of two layers of your tooth: the outer layer made of enamel called the extrinsic level or the softer inner dentin layer called the intrinsic level. Extrinsic staining occurs due to consuming darkly-pigmented food or drinks like coffee, tea or berries or cigarette or cigar smoke coming into contact with the teeth. Intrinsic staining occurs due to taking certain medications or trauma to the tooth. In addition to extrinsic and intrinsic staining, teeth can become discolored due to the enamel wearing thin as you age. This normal wear and tear causes the yellow-colored dentin layer to begin showing through the lighter colored enamel, causing a yellowed appearance.
Avoiding Tooth Discolorations in Silver Spring, MD
Avoiding stains is as easy as avoiding what causes them. Cutting out stain causers like coffee, tea and tobacco will eliminate the possibility that these things can stain your teeth at all. However, many people are not willing to avoid these things. To decrease the chance of stains, try to limit the time the stain-causing elements come into contact with your teeth and be sure to brush twice a day and floss at least once. For example, drink your morning coffee or tea in one sitting rather than sipping it throughout the day.

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.

Proactive dental care is an essential part of childhood growth. But that care can be much harder for children with chronic health issues than for healthier children.
“Chronic condition” is an umbrella term for any permanent and ongoing health issue. Asthma, Down’s syndrome, cystic fibrosis, congenital heart defects and many others fall under this umbrella, with varying symptoms and degrees of intensity. But they all have one common characteristic — a long-term effect on all aspects of a child’s health.
That includes the health of a child’s teeth and gums. Here, then, are a few areas where a chronic health condition could impact dental care and treatment.
Ineffective oral hygiene. Some chronic conditions like autism or hyperactivity disorder (ADHD) that affect behavior or cognitive skills can decrease a child’s ability or willingness to brush or floss; some conditions may also limit their physical ability to perform these tasks. Parents and caregivers may need to seek out tailored training for their child’s needs, or assist them on a regular basis.
Developmental defects. Children with chronic conditions are also more likely to have other developmental problems. For example, a child with Down, Treacher-Collins or Turner syndromes mayÂ be more likely to develop a birth defect called enamel hypoplasia in which not enough tooth enamel develops. Children with this defect must be monitored more closely and frequently for tooth decay.
Special diets and medications. A child with a chronic condition may need to eat different foods at different times as part of their treatment. But different dietary patterns like nutritional shakes or more frequent feedings to boost caloric intake can increase risk for tooth decay. Likewise, children on certain medications may develop lower saliva flow, leading to higher chance of disease. You’ll need to be more alert to the signs of tooth decay if your child is on such a diet or on certain medications, and they may need to see the dentist more often.
While many chronic conditions raise the risk of dental disease, that outcome isn’t inevitable. Working with your dentist and remaining vigilant with good hygiene practices, your special needs child can develop and maintain healthy teeth and gums.

During his former career as a professional footballer (that's a soccer star to U.S. sports fans) David Beckham was known for his skill at “bending” a soccer ball. His ability to make the ball curve in mid-flight — to avoid a defender or score a goal — led scores of kids to try to “bend it like Beckham.” But just recently, while enjoying a vacation in Canada with his family, “Becks” tried snowboarding for the first time — and in the process, broke one of his front teeth.
Some fans worried that the missing tooth could be a “red card” for Beckham's current modeling career… but fortunately, he headed straight to the dental office as soon as he arrived back in England. Exactly what kind of treatment is needed for a broken tooth? It all depends where the break is and how badly the tooth is damaged.
For a minor crack or chip, cosmetic bonding may offer a quick and effective solution. In this procedure, a composite resin, in a color custom-made to match the tooth, is applied in liquid form and cured (hardened) with a special light. Several layers of bonding material can be applied to re-construct a larger area of missing tooth, and chips that have been saved can sometimes be reattached as well.
When more tooth structure is missing, dental veneers may be the preferred restorative option. Veneers are wafer-thin shells that are bonded to the front surface of the teeth. They can not only correct small chips or cracks, but can also improve the color, spacing, and shape of your teeth.
But if the damage exposes the soft inner pulp of the tooth, root canal treatment will be needed to save the tooth. In this procedure, the inflamed or infected pulp tissue is removed and the tooth sealed against re-infection; if a root canal is not done when needed, the tooth will have an increased risk for extraction in the future. Following a root canal, a tooth is often restored with a crown (cap), which can look good and function well for many years.
Sometimes, a tooth may be knocked completely out of its socket; or, a severely damaged tooth may need to be extracted (removed). In either situation, the best option for restoration is a dental implant. Here, a tiny screw-like device made of titanium metal is inserted into the jaw bone in a minor surgical procedure. Over time, it fuses with the living bone to form a solid anchorage. A lifelike crown is attached, which provides aesthetic appeal and full function for the replacement tooth.
So how's Beckham holding up? According to sources, “David is a trooper and didn't make a fuss. He took it all in his stride." Maybe next time he hits the slopes, he'll heed the advice of dental experts and wear a custom-made mouthguard…
