Until recently anyone who needed to repair cavities in his or her teeth ended up with a mouth full of “silver” fillings. Dental amalgam, which has a silver appearance, was the tooth restoration material of choice. Amalgam, a combination of metals including silver, mercury, and other metals, is still used — but today there are other options that mimic the original teeth they are restoring.
You may have read about some people's concerns about the mercury used in dental amalgam. According to the American Dental Association (ADA), scientific studies have found no ill effects arising from using dental amalgam in fillings for adults or children: “While questions have arisen about the safety of dental amalgam relating to its mercury content, the major US and international scientific and health bodies, including the National Institutes of Health, the US Public Health Service, the Centers for Disease Control and Prevention, the Food and Drug Administration and the World Health Organization, among others have been satisfied that dental amalgam is a safe, reliable and effective restorative material.” Dental amalgam is still used for molars (back teeth) that must withstand heavy pressure from chewing.
For teeth that are more visible, materials that look and perform more like the original teeth — and are thus more pleasing in appearance — are now available. Dentistry is now taking a “biomimetic approach” (from words meaning “life mimicking”). The new materials — composite resins and porcelains — look like teeth because in many ways their structure imitates the biologic structure of teeth.
Composite resins are made of a plastic material (methacrylate) combined with fillers made of silica, a form of glass. They are able to bond to natural tooth structure and resemble the dentin, the inner layer of the tooth, which has a porous structure similar to bone.
Dental porcelains are a form of ceramic. They are non-metallic materials formed by the action of heat, like the ceramics used in porcelain cups and bowls. They come in a powder form that is mixed with water, shaped, and then placed in an oven until they reach the proper hardness. The end product is translucent and very hard, resembling the densely packed crystals of calcium that make up a tooth's normal outer layer, the enamel.
The old amalgam fillings required removal of tooth material to prepare a site in which they could be placed. Composite resins and porcelains can be used to treat teeth that have small or large amounts of damage to their natural substance because the materials bond directly to the remaining dentin and enamel. Thus they end up stabilizing and strengthening the restored tooth, as well as providing a natural-looking appearance.

Tooth pain occurs when a trauma or infection triggers a reaction from the nerves inside a tooth's pulp chamber. The severity of the pain and its duration can vary depending on the underlying cause, which can include anything from a loose filling to an abscess. Ignoring symptoms not only results in unnecessary physical and emotional pain, but can also lead to more expensive dental treatment as problems become more complex. Make an appointment with our office today if you are experiencing any of the following symptoms:
- Sharp pain when biting down on food — This type of pain could be indicative of a cracked tooth, loose filling, or tooth decay that is affecting one or more of your teeth. We can remove decay and replace a loose filling, but if your tooth is cracked, we will have to determine the location and depth of the crack before formulating a treatment plan. In some cases, root canal treatment or even extraction may be necessary.
- Pain that lingers after eating hot or cold foods or liquids — Mild and short-term sensitivity (lasting only seconds or a minute) to hot and cold foods resulting from gum recession can often be soothed by using a fluoride toothpaste made for sensitive teeth. However, an inflamed tooth pulp or one that is dying due to severe decay could cause sensitivity that lingers for a long time after exposure. In this case, root canal treatment may be necessary to remove dying pulp tissue in order to save the tooth.
- Constant severe pain and pressure, swelling of the gums, and sensitivity to touch — Infections and/or abscesses can spread from the tooth pulp into the surrounding periodontal tissues and bone causing this type of pain. Root canal treatment will most likely be required.
- Dull ache and pressure on one or both sides of the face in the upper teeth region — The sinuses and upper back teeth share the same nerves, so, oftentimes, referred pain from sinus congestion or infection can feel like a toothache. A thorough examination can determine whether or not the pain is dentally related.
If you are experiencing tooth pain, call our office immediately so that we can begin to provide you with some relief. To read about other symptoms of tooth pain and possible treatment options, read the Dear Doctor magazine article “Tooth Pain? Don't Wait!”
Oral cancer is on the rise in the United States, yet few people are familiar with the disease and its risk factors. The National Institute of Dental and Craniofacial Research (NIDCR) estimates that 35,000 Americans are diagnosed with the disease each year. The good news is that prevention and early detection can greatly reduce your risk of developing oral cancer.
Risk Factors for Oral Cancer Include:
- Tobacco: Smoking and using chewing tobacco have been shown to increase the risk of developing oral cancer.
- HPV virus: The Human Papilloma Virus (HPV) is the same virus linked to cervical cancer and genital warts. According to the Oral Cancer Foundation (OCF), many young people and women are being diagnosed with oral cancer as a result of exposure to the HPV virus.
- Age: Although it occurs more frequently in people over the age of 40, the incidence is increasing in younger people.
- Alcohol Consumption: Oral cancer is six times more common in those who drink alcohol excessively.
- Diet: People who consume lots of red and processed meat and fried foods are at greater risk.
Symptoms: Alert our office if you notice a change in your mouth such as a sore that doesn't heal or bleeds easily; a lump, thickening, crust or erosion; pain or tenderness; or a change in the way your teeth are positioned. Our office can administer an easy, painless test that detects abnormal cells.
Other symptoms may include unexplained bleeding or numbness in the mouth, difficulty chewing, swallowing or speaking, hoarseness, chronic sore throat or changes in your voice.
Importance of Dental Screenings: In its early stages, oral cancer can often go unnoticed, but visiting our office regularly can ensure that any cancerous cells are detected and treated early. Our office will check your tongue and the area under your tongue, as well as your lips and palate and the back of your mouth.

Nearly everyone who has ever played a sport, or had a child participate in one, has had that panic-filled moment when they witness an injury. And when you consider that there are more than 22,000 dental injuries each year in children younger than 18 years of age, you see there is fact to backup this concern. This is just one reason why we strongly encourage all of our patients who are involved in activities such as football, soccer, hockey, wrestling, lacrosse, skateboarding, field hockey and more to wear one of our custom-fitted professional mouthguards. It is especially true for basketball and baseball, which are responsible for the largest number of dental injuries.
The following are some key issues to help you understand the importance and advantages mouthguards offer.
Is there a way to determine who is at the highest risk for sports injuries?
Yes there are several. Age, gender, dental anatomy, and the type of sports being played are the four categories used to measure the risks for dental injuries. Young male teens still top the list of most likely to be injured; however, the gap is closing with more females getting involved in sports. Learn which sports or exercise activities made the American Dental AssociationÃ¢Â€Â™s list of recommendations for using a custom mouthguard, when you continue reading “Athletic Mouthguards.”
What's the difference between a “boil and bite” mouthguard and a professionally made mouthguard?
We are often asked this very important question. While some over-the-counter (OTC) mouthguards provide what is advertised as a “custom-fit” to your teeth, it is nowhere near the fit — and thus protection — you receive from our mouthguards that are crafted from precise molds of your teeth. Additionally, because all aspects of our mouthguards are tailored to each specific mouth, they provide much more protection and comfort. This important fact can enhance performance as the athlete can literally breathe easier while wearing one of our mouthguards.
What can I do if I witness a dental injury?
The first important fact to know is that you do not have to be a dental or healthcare professional to assist. However, before jumping in to help out, consult Dear Doctor's Field-Side Guide to Dental Injuries. This pocket-sized, quick-reference guide details what you should do at the scene of a dental injury based on the type of injury. But best of all, it is available to you free of charge from Dear Doctor.
