Below are some of the most frequently asked questions patients have about dentistry and oral health issues. If you have any other questions or would like to schedule an appointment, we would love to hear from you.
Are amalgam (silver) fillings safe?
Over the years, there have been some concerns as to the safety of amalgam (silver) fillings. An amalgam is a blend of copper, silver, tin, and zinc, bound by elemental mercury. Dentists have used this blended metal to fill teeth for more than 100 years. The controversy is due to claims that the exposure to the vapor and minute particles from the mercury can cause a variety of health problems.
According to the American Dental Association (ADA), up to 76% of dentists use silver containing mercury to fill teeth. The ADA also states that silver fillings are safe and that studies have failed to find any link between silver containing mercury and any medical disorder.
The general consensus is that amalgam (silver) fillings are safe. Along with the ADA’s position, the Centers for Disease Control and Prevention (CDC), the World Health Organization, the U.S. Food and Drug Administration, and others support the use of silver fillings as safe, durable, and cost-effective. The U.S. Public Health Service says that the only reason not to use silver fillings is when a patient has an allergy to any component of this type of filling. The ADA has had fewer than 100 reported incidents of an allergy to components of silver fillings, and this is out of countless silver fillings over the decades.
Although studies indicate that there are no measurable health risks to patients who have silver fillings, we do know that mercury is a toxic material when we are exposed at high, unsafe levels. For instance, we have been warned to limit the consumption of certain types of fish that carry high levels of mercury in them. However, with respect to amalgam fillings, the ADA maintains that when the mercury combines with the other components of the filling, it becomes an inactive substance that is safe.
There are numerous options to silver fillings, including composite (tooth-colored), porcelain, and gold fillings. We encourage you to discuss these options with your dentist so you can determine which is the best option for you.
How can I tell if I have gingivitis or periodontitis (gum disease)?
Most people who have periodontal disease are not aware of it because the disease is usually painless in the early stages. Unlike tooth decay, which often causes discomfort, it is possible to have periodontal disease without noticeable symptoms. Having regular dental check-ups and periodontal examinations are very important and will help detect if periodontal problems exist.
Periodontal disease begins when plaque, a sticky, colorless, film of bacteria, food debris, and saliva, is left on the teeth and gums. The bacteria produce toxins (acids) that inflame the gums and slowly destroy the bone. Brushing and flossing regularly and properly will ensure that plaque is not left behind to do its damage.
Other than poor oral hygiene, there are several other factors that may increase the risk of developing periodontal disease:
- Smoking or chewing tobacco – Tobacco users are more likely than nonusers to form plaque and tartar on their teeth.
- Certain tooth or appliance conditions – Bridges that no longer fit properly, crowded teeth, or defective fillings that may trap plaque and bacteria.
- Many medications – Some medications have side effects that reduce saliva, making the mouth dry and plaque easier to adhere to the teeth and gums. Examples include steroids, cancer therapy drugs, blood pressure meds, and oral contraceptives.
- Pregnancy, oral contraceptives, and puberty – Can cause changes in hormone levels, causing gum tissue to become more sensitive to bacteria toxins.
- Systemic diseases – Diabetes, blood cell disorders, HIV / AIDS, etc.
- Genetics may play role – Some patients may be predisposed to a more aggressive type of periodontitis. Patients with a family history of tooth loss should pay particular attention to their gums.
Good oral hygiene, a balanced diet, and regular dental visits can help reduce your risk of developing periodontal disease.
How can cosmetic dentistry help improve the appearance of my smile?
If you’re feeling somewhat self-conscious about your teeth, or just want to improve your smile, cosmetic dental treatments may be the answer to a more beautiful, confident smile.
Cosmetic dentistry has become very popular in the last several years, not only due the many advances in cosmetic dental procedures and materials available today, but also because patients are becoming more and more focused on improving their overall health.

What can I do about stained or discolored teeth?
Since teeth whitening has now become the No. 1 aesthetic concern of many patients, there are many products and methods available to achieve a brighter smile.
Professional teeth whitening (or bleaching) is a simple, non-invasive dental treatment used to change the color of natural tooth enamel, and is an ideal way to enhance the beauty of your smile. Over-the-counter products are also available, but they are much less effective than professional treatments and may not be approved by the American Dental Association (ADA).
As we age, the outer layer of tooth enamel wears away, eventually revealing a darker or yellow shade. The color of our teeth also comes from the inside of the tooth, which may become darker over time. Smoking, drinking coffee, tea, and wine may also contribute to tooth discoloration, making our teeth yellow and dull. Sometimes, teeth can become discolored from taking certain medications as a child, such as tetracycline. Excessive fluoridation (fluorosis) during tooth development can also cause teeth to become discolored.
It’s important to have your teeth evaluated by your dentist to determine if you’re a good candidate for bleaching. Occasionally, tetracycline and fluorosis stains are difficult to bleach and your dentist may offer other options, such as veneers or crowns to cover up such stains. Since teeth whitening only works on natural tooth enamel, it is also important to evaluate the replacement of any old fillings, crowns, etc. before bleaching begins. Once the bleaching is done, your dentist can match the new restorations to the shade of the newly whitened teeth.
Since teeth whitening is not permanent, a touch-up may be needed every several years to keep your smile looking bright.
Teeth whitening can be very effective and can give you a brighter, whiter, more confident smile!
