Cosmetic Fillings
Frequently Asked Questions About Dental Fillings
Are dental amalgams safe? Is it possible to have an allergic reaction to amalgam? Is it true that dental amalgams have been banned in other countries? Is there a filling material that matches tooth color? If my tooth doesn’t hurt and my filling is still in place, why would the filling need to be replaced? Read this interesting and informative discussion from the American Dental Association.
FDA Consumer Update: Dental Amalgams
The Food and Drug Administration and other organizations of the U.S. Public Health Service (USPHS) continue to investigate the safety of amalgams used in dental restorations (fillings). However, no valid scientific evidence has shown that amalgams cause harm to patients with dental restorations, except in rare cases of allergic reactions.

Analysis reveals significant drop in children's tooth decay
Children have significantly less tooth decay in their primary (baby) and permanent teeth today than they did in the early 1970s, according to the Journal of the American Dental Association (JADA). The analysis reveals that among children between the ages of six and 18 years, the percentage of decayed permanent teeth decreased by 57.2 percent over a 20-year period. In addition, children between the ages of two and 10 years experienced a drop of nearly 40 percent in diseased or decayed primary teeth.
Alternative Materials
Here's a look at some of the more common kinds of alternatives to silver amalgam:
- Composite fillings – Composite fillings are a mixture of acrylic resin and finely ground glasslike particles that produce a tooth-colored restoration. Composite fillings provide good durability and resistance to fracture in small-to-mid size restorations that need to withstand moderate chewing pressure. Less tooth structure is removed when the dentist prepares the tooth, and this may result in a smaller filling than that of an amalgam. Composites can also be “bonded” or adhesively held in a cavity, often allowing the dentist to make a more conservative repair to the tooth. In teeth where chewing loads are high, composite fillings are less resistant to wear than silver amalgams. It also takes longer to place a composite filling.
- Ionomers – Glass ionomers are tooth-colored materials made of a mixture of acrylic acids and fine glass powders that are used to fill cavities, particularly those on the root surfaces of teeth. Glass ionomers can release a small amount of fluoride that help patients who are at high risk for decay. Glass ionomers are primarily used as small fillings in areas that need not withstand heavy chewing pressure. Because they have a low resistance to fracture, glass ionomers are mostly used in small non-load bearing fillings (those between the teeth) or on the roots of teeth. Resin ionomers also are made from glass filler with acrylic acids and acrylic resin. They also are used for non-load bearing fillings (between the teeth) and they have low to moderate resistance to fracture. Ionomers experience high wear when placed on chewing surfaces. Both glass and resin ionomers mimic natural tooth color but lack the natural translucency of enamel. Both types are well tolerated by patients with only rare occurrences of allergic response.
- Porcelain (ceramic) dental materials – All-porcelain (ceramic) dental materials include porcelain, ceramic or glasslike fillings and crowns. They are used as inlays, onlays, crowns and aesthetic veneers. A veneer is a very thin shell of porcelain that can replace or cover part of the enamel of the tooth. All-porcelain (ceramic) restorations are particularly desirable because their color and translucency mimic natural tooth enamel. All-porcelain restorations require a minimum of two visits and possibly more. The restorations are prone to fracture when placed under tension or on impact. Their strength depends on an adequate thickness of porcelain and the ability to be bonded to the underlying tooth. They are highly resistant to wear but the porcelain can quickly wear opposing teeth if the porcelain surface becomes rough.
Other Dental Services
In general dentistry, the dentist is the primary care provider for patients of all ages and is responsible for the prevention, diagnosis and treatment of a wide variety of conditions, disorders and diseases affecting the teeth, gums and maxillofacial (jaw and face) parts of the body.
From minor tweaks to major makeovers, we offer a comprehensive range of cosmetic services to fit any patient’s needs, lifestyle and oral health.
Bonding is a process in which an enamel-like material is applied to a tooth’s surface, sculpted to an ideal shape, hardened, and then polished for an ideal smile.
Crowns are synthetic caps, usually made of a material like porcelain, placed on the top of a tooth. Crowns are typically used to restore a tooth’s function and appearance following a restorative procedure such as a root canal.
Sealants act as a barrier to prevent bacteria and food from collecting and sitting on the grooves and pits of teeth.
Implants are synthetic structures that are placed in the area of the tooth normally occupied by the root. Implants act as a foundation for an artificial tooth or permanent bridge.
Veneers are thin pieces of porcelain or plastic cemented over the front of your teeth to change their color or shape. Veneers are used on teeth with uneven surfaces or are chipped, discolored, oddly shaped, unevenly spaced or crooked.
Whitening procedures have effectively restored the smile of people with stained, dull, or discolored teeth.The darker tissue of your teeth, the dentin, can become exposed as the outer layer of enamel is worn away by the effects of aging or things like caffeine and tobacco.
Invisalign’s® invisible, removable, and comfortable aligners will give you the beautiful straight teeth you’ve always wanted. And best of all, no one can tell you’re wearing them. Invisalign is great for adults and teenagers.
Sealants are liquid coatings that harden on the chewing surfaces of teeth and are showing a great deal of effectiveness in preventing cavities—even on teeth where decay has begun.
When restoration procedures such as root canal therapy, crowns, or fillings are not enough to save a tooth, it may need to be pulled, or extracted.
Simple toothaches can often be relieved by rinsing the mouth to clear it of debris and other matter. A broken, fractured or displaced tooth is usually not a cause for alarm, as long as decisive, quick action is taken.
Root canal therapy is a remarkable treatment with a very high rate of success, and involves removing the diseased tissue, halting the spread of infection and restoring the healthy portion of the tooth.
A denture is a removable replacement for missing teeth and adjacent tissues. It is made of acrylic resin, sometimes in combination with various metals.
Some cases of acute periodontal (gum) disease that do not respond to more conventional treatment and self-care such as flossing may require a special kind of cleaning called scaling and root planing.
A knocked out tooth or bitten tongue can cause panic in any patient, but quick thinking and staying calm are the best ways to approach such common dental emergencies and prevent additional unnecessary damage and costly dental restoration. Please contact our office as soon as possible.
Soft tissue grafts are sometimes performed to treat gum disease, or correct other abnormalities. The procedure involves taking gum tissue from the palate or another donor source to cover an exposed root in order to even the gum line and reduce sensitivity.
