For over a hundred years dental amalgam — a combination of silver, mercury, tin and other metals — has been an effective filling material for teeth damaged by decay. But it has one major drawback — its metallic appearance stands out in stark contrast to the natural color of teeth.
As an alternative, composite resin fillings can match the color, shape and texture of natural teeth. These materials and the techniques used to bond them are proving just as effective as and more aesthetically pleasing than dental amalgam.
Fillings help protect and preserve a decayed tooth. By first removing decayed tooth structure through drilling, the resulting void is filled with durable material that strengthens the tooth and provides it protection from further decay.
The ultimate goal for restoration is to return the tooth to as near normal form and function as possible. Dental amalgam serves well in terms of function, providing the tooth strength in the face of the daily biting forces it encounters. In contrast, composite resins excel in appearance, but haven’t always matched the durability of amalgam. They’re material construction has improved over time, though, as well as the techniques used to bond them to teeth.
Most of these bonding techniques incorporate layering. The first step is to seal the dentin (the porous, living tissue just below the enamel); we then build up the composite material layer by layer within the tooth using special bonding adhesive and curing lights. In some cases where a large volume of tooth structure must be replaced, the restoration is first formed on the tooth and then removed for curing before being cemented into the tooth or a separate restoration is formed by a dental lab.
The end result is a tooth which both looks and functions like a fully intact tooth. Though care must be taken not to subject composite resin restorations to undue forces (no cracking open nutshells, for example), your new filling should continue to serve you and look great for a long time to come.

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.

While tooth decay is a potential problem at any age, the risk increases as you grow older. Not only are senior adults more susceptible, decay is often more difficult to treat. That’s because cavities can occur at or below the gum line, often due to gum recession.
If that’s the case, we won’t be able to fill the cavity in the usual way because the gum tissue is in the way. To make it possible to treat, we may need to perform a minor surgical procedure known as crown lengthening.
As the name implies, the procedure helps expose more of the crown, the tooth’s visible part, from the surrounding gum tissue. In basic terms, we’re repositioning the gum tissue away from the biting surface of a tooth to make room for a filling. It’s also useful for improving a tooth’s appearance by making it look longer, or creating room for a crown or other dental restoration.
After applying a local anesthesia, the dentist (or periodontist, a specialist in the gums) creates a tiny flap of gum tissue with a series of incisions. This allows the dentist to move the affected gums out of the way to access the underlying bone. The dentist then reshapes the bone to adequately support the gum tissue when it’s finally repositioned to expose the crown. In its new and improved position, the dentist sutures the gum tissue in place.
For a few days afterward, the patient will need to restrict their diet to soft foods, avoid strenuous activities and apply an ice pack to help reduce swelling the day of surgery. They will also prescribe a pain reliever and possibly an antibiotic to reduce the chances of infection.
While most people return to normal activities a few days later, you’ll usually have to wait a few weeks for the gums to heal before undergoing any further treatments for the affected teeth. But even with the wait, crown lengthening could make it possible to not only save your tooth but improve your smile as well.
