All crowns are designed to restore functionality to a damaged tooth. But crowns can differ from one another in their appearance, in the material they’re made from, and how they blend with other teeth.
A crown is a metal or porcelain artifice that’s bonded permanently over a decayed or damaged tooth. Every crown process begins with preparation of the tooth so the crown will fit over it. Afterward, we make an impression of the prepared tooth digitally or with an elastic material that most often is sent to a dental laboratory to create the new crown.
It’s at this point where crown composition and design can diverge. Most of the first known crowns were made of metal (usually gold or silver), which is still a component in some crowns today. A few decades ago dental porcelain, a form of ceramic that could provide a tooth-like appearance, began to emerge as a crown material. The first types of porcelain could match a real tooth’s color or texture, but were brittle and didn’t hold up well to biting forces. Dentists developed a crown with a metal interior for strength and a fused outside layer of porcelain for appearance.
This hybrid became the crown design of choice up until the last decade. It is being overtaken, though, by all-ceramic crowns made with new forms of more durable porcelain, some strengthened with a material known as Lucite. Today, only about 40% of crowns installed annually are the metal-porcelain hybrid, while all-porcelain crowns are growing in popularity.
Of course, these newer porcelain crowns and the attention to the artistic detail they require are often more expensive than more traditional crowns. If you depend on dental insurance to help with your dental care costs, you may find your policy maximum benefit for these newer type crowns won’t cover the costs.
If you want the most affordable price and are satisfied primarily with restored function, a basic crown is still a viable choice. If, however, you would like a crown that does the most for your smile, you may want to consider one with newer, stronger porcelain and made with greater artistic detail by the dental technician. In either case, the crown you receive will restore lost function and provide some degree of improvement to the appearance of a damaged tooth.
Over the last century effectively treating a decayed tooth has often required removing any decayed structure with drilling and then filling the remaining cavity. While this approach does save teeth that might otherwise be lost, it can also result in a fair amount of healthy structure removed in the process.
But continuing advances in dentistry are now making possible a new approach to tooth decay treatment that preserves as much of the healthy portions of tooth as possible. This new way is often referred to as minimally invasive dentistry (MID).
The primary goal of MID treatment is to intercept and treat decay as early as possible to minimize tooth damage. It begins with helping patients identify their own individual risk factors for decay such as the presence of disease-causing bacteria, the adequacy of their saliva flow, or their lifestyle and dietary habits. We then recommend changes or preventive measures to reduce those risks.
The next step in MID is using various diagnostic technologies to find decay as early as possible. X-rays continue to play a major role, but dentists are also using dental microscopy to magnify the earliest forms of decay. Many also utilize laser fluorescence, infrared photography and optical scanning to further “see” decay difficult to detect with the naked eye.
In regard to treatments, MID adopts the adage “less is more.” If caught early enough, we can encourage the re-mineralization of enamel that acid has eroded with CPP-ACP, a substance acquired from milk, or strengthen teeth with topical fluoride applications. Instead of the dental drill, many dentists now turn to air abrasion for decay removal, equipment that emits a fine stream of abrasive particles that harms less healthy structure than a drill.
And if lasers continue to develop at their current pace, we’ll be able to use this technology to perform much more precise decay treatment than possible with manual instruments. As a result, we’ll be able to treat decayed teeth with less invasive means to preserve as much healthy structure as possible.
As these and other developments continue, MID promises a bright future for preventing and treating tooth decay. As a result, there’ll be less tooth structure loss and more attractive and healthy smiles.

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.

Here’s a sobering statistic: you have a 50/50 chance over your lifetime for developing periodontal (gum) disease. And it’s much more serious than irritated gums: if not treated aggressively you could experience bone loss, which can not only lead to tooth loss but actually increases your risk of heart attack and stroke.
Initially, you may not notice any symptoms unless you know what to look for: mainly red and puffy gums that frequently bleed during brushing and flossing. As the infection advances into the underlying support structures that hold teeth in place you may also notice receding gums (moving away from your teeth causing them to look longer), pus around the gums or lingering bad breath or taste. And one or more loose teeth are a definite sign the supporting structures have weakened severely.
So, how does gum disease happen? It starts with bacteria. Your mouth contains millions of these and other microorganisms, most of which are friendly and even beneficial. Unfortunately, a fraction of them can infect and harm tissues like the gums and underlying bone. Your mouth’s defenses can normally handle them if their numbers remain low. But a bacterial population explosion can quickly overwhelm those defenses.
Bacteria are like any other life form: they need a secure environment and food. Disease-causing bacteria establish the former by utilizing proteins and other components of saliva to form a sticky biofilm on teeth known as plaque. Within the safe haven of dental plaque bacteria quickly multiply and form a complex and concentrated ecosystem feeding on remnant food particles, especially sugar and other carbohydrates.
The key to gum disease prevention (as well as treatment) is to deprive bacteria of their home and food source by removing plaque and its more hardened form calculus (tartar). You can manage plaque buildup by brushing and flossing daily, seeing your dentist regularly for cleanings to remove any remaining hard-to-reach plaque and calculus, and eating a nutritious diet with fewer sweets or other carbohydrate-rich snacks.
You can further lower your disease risk by avoiding smoking and other tobacco products and moderating your consumption of alcohol. And be sure to see your dentist as soon as possible if you notice any signs of infection with your gums. Taking these steps can help you avoid gum disease’s destructiveness and help preserve a healthy and attractive smile.
Sports drinks have been widely touted as an ideal way to replenish carbohydrates, electrolytes and, of course, fluids after a strenuous event or workout. But the mixtures of many popular brands often contain acid and added sugar, similar to other types of soft drinks. This can create an acidic environment in the mouth that can be damaging to tooth enamel.
Of course, the best way to replenish fluids after most strenuous activities is nature’s hydrator, water. If, however, you or a family member does drink the occasional sports beverage, you can help reduce the acid impact and help protect tooth enamel by following these 3 tips.
Avoid sipping a sports drink over long periods. Sipping on a drink constantly for hours interferes with saliva, the bodily fluid responsible for neutralizing mouth acid. But because the process can take thirty minutes to an hour to bring the mouth to a normal pH, saliva may not be able to complete neutralization because of the constant presence of acid caused by sipping. It’s best then to limit sports drinks to set periods or preferably during mealtimes.
Rinse your mouth out with water after drinking.Â Enamel damage occurs after extended periods of exposure to acid. Rinsing your mouth out immediately after consuming a sports drink will wash away a good amount of any remaining acid and help normalize your mouth’s pH level. And since water has a neutral pH, it won’t add to the acid levels.
Wait an hour to brush after eating. As mentioned before, saliva takes time to neutralize mouth acid. Even in that short period of time, though, acid can soften some of the mineral content in enamel. If you brush during this “soft” period, you may inadvertently brush away some of the minerals. By waiting an hour, you give saliva time not only to neutralize acid but also restore mineral strength to the enamel.
