Human beings have known for millennia the importance of keeping teeth clean. Although we've only come to more fully understand dental plaque's role in dental disease in the last century, our ancestors seemed to know instinctively this gritty biofilm on teeth had to go.
People from the past once used a variety of substances like ground oyster shells or leftover fire ashes to remove plaque from their teeth. Today, most of the world has replaced these substances with toothpaste, a mainstay of daily oral hygiene.
So, why is toothpaste better than other substances used in the ancient past? Besides the many other ingredients found in the typical tube of toothpaste, here are the top 3 that make it the ultimate tooth cleaner.
Abrasives. While your toothbrush does most of the mechanical work loosening plaque, toothpaste has ingredients called abrasives that give an added boost to your brushing action. The ideal abrasive is strong enough to remove plaque, but not enough to damage tooth enamel. If you look at your toothpaste's ingredient list, you'll probably see an abrasive like hydrated silica (made from sand), hydrated alumina, calcium carbonate or dicalcium phosphates.
Detergents. Your toothpaste's foaming action is a sign of a detergent, which helps loosen and break down non-soluble (not dissolvable with plain water) food substances. While similar to what you may use to wash your clothes or dishes, toothpaste detergents are much milder, the most common being sodium lauryl sulfate found in many cosmetic items. If you have frequent canker sores, though, sodium lauryl sulfate can cause irritation, so look for a toothpaste with a different detergent.
Fluoride. The enamel strengthening power of fluoride was one of the greatest discoveries in dental care history. Although not all toothpastes contain it, choosing one with fluoride can improve your enamel health and help protect you from tooth decay.
These and other ingredients like binders, preservatives and flavorings, all go in to make toothpaste the teeth-cleaning, disease-fighting product we've all come to depend upon. Used as part of daily oral hygiene, toothpaste can help brighten and freshen your smile, and keep your teeth and gums healthy.

Whether she’s singing, dancing or acting, Jennifer Lopez is a performer who is known for giving it all she’s got. But during one show, Lopez recently admitted, she gave a bit more then she had planned.
“I chipped my tooth on stage,” she told interviewers from Entertainment Tonight, “and had to finish the show….I went back thinking ‘Can I finish the show like this?’”
With that unlucky break, J-Lo joins a growing list of superstar singers—including Taylor Swift and Michael Buble—who have something in common: All have chipped their teeth on microphones while giving a performance.
But it’s not just celebs who have accidental dental trouble. Chips are among the most common dental injuries—and the front teeth, due to their position, are particularly susceptible. Unfortunately, they are also the most visible. But there are also a number of good ways to repair chipped, cracked or broken teeth short of replacing them.
For minor to moderate chips, cosmetic bonding might be recommended. In this method, special high-tech resins, in shades that match your natural teeth, are applied to the tooth’s surface. Layers of resin, cured with a special light, will often restore the tooth to good appearance. Best of all, the whole process can often be done in just one visit to the dental office, and the results can last for several years.
For a more permanent repair—or if the damage is more extensive—dental veneers may be another option. Veneers are wafer-thin shells that cover the entire front surface of one or more teeth. Strong, durable and natural-looking, they can be used to repair moderate chips, cracks or irregularities. They can also help you get a “red-carpet” smile: brilliant white teeth with perfectly even spacing. That’s why veneers are so popular among Hollywood celebs—even those who haven’t chipped their teeth!
Fortunately, even if the tooth is extensively damaged, it’s usually possible to restore it with a crown (cap), a bridge—or a dental implant, today’s gold standard for whole-tooth replacement. But in many cases, a less complex type of restoration will do the trick.
Which tooth restoration method did J-Lo choose? She didn’t say—but luckily for her adoring fans, after the microphone mishap she went right back up on stage and finished the show.
If you have a chipped tooth but you need to make the show go on, please contact us or schedule an appointment for a consultation. You can also learn more by reading the Dear Doctor magazine articles “Artistic Repair of Chipped Teeth With Composite Resin” and “Porcelain Veneers.”
Whether performed in a dental office or using a home kit, teeth whitening applications are quite effective for bleaching exterior (extrinsic) stains on enamel surfaces. But what if your discoloration comes from inside the tooth? In this case, extrinsic teeth whitening won’t work — you’ll need to undergo an “internal bleaching” method, which can only be performed in a dentist's office.
There are a number of causes for “intrinsic” staining, including too much fluoride exposure or tetracycline use during childhood. One of the more common causes, though, occurs from root canal treatments used to remove the remnants of the pulp tissue inside a tooth’s pulp chamber and root canals. Certain cements used during the procedure to help seal in the filling material and leftover blood pigments can cause the tooth to darken over time.
To alleviate this discoloration, we use a bleaching agent, usually sodium perborate mixed with a diluted solution of hydrogen peroxide to achieve a safe, accelerated color change. After determining that the root canal filling is still intact and the bone is healthy, we create a small cavity in the back of the tooth to access the pulp chamber. The chamber is cleaned of any debris or stained material and then thoroughly irrigated. The original root canal filling is then sealed off to prevent leakage from the bleaching agent.
We then place the bleaching agent in the cleaned-out space with a cotton pellet and seal it in with a temporary adhesive. This step is repeated for several days until we achieve the desired shade of white. Once that occurs we then seal the dentin with a more permanent filling and then restore the cavity we created with a composite resin bonded to the enamel and dentin.
If we’re successful in achieving the desired color, intrinsic whitening could help you avoid more costly options like veneers or crowns for an otherwise healthy and attractive tooth. The end result would be the same — a beautiful smile without those unsightly stains.

Bacteria are bad… right? They can cause diseases like pneumonia, strep throat, and tooth decay. They are the reason we wash our hands with soap (or antibacterial gels) and cook (or refrigerate) our food. Yet it turns out that bacteria are also necessary to keep our bodies healthy — and new research is showing just how important these tiny microorganisms are to our well-being. Here are five facts you should know about bacteria.
The bacteria in our bodies outnumber our cells by a factor of 10 to 1. An estimated 100 trillion bacteria live inside the average human — but because they’re so small, they make up only 1-3 percent of our body mass.
The collection of bacteria we harbor is called our “microbiome.” Like the groundbreaking study of human DNA called the Human Genome Project, recent research is leading to a “map” of our bacterial makeup. This revolutionary study is called — you guessed it — the Human Microbiome Project.
No two people have exactly the same microbiome. But in general, the bacteria that live in a particular spot on the body (the mouth, for example) play the same roles in different individuals. Research has also shown that a healthy microbiome looks very different from a diseased microbiome.
In terms of bacteria, the mouth is one of the best-understood areas of the body. It has long been known that tooth decay can result when “bad” oral bacteria begin to outnumber their “good” counterparts. Now we are gaining a better understanding of how certain lifestyle factors — like cigarette smoking — may influence the bacterial balance in the mouth.
Understanding the microbiome may lead to new treatments for disease. Researchers hope that one day, certain serious diseases could be controlled by bacterial “transplants” that re-balance an individual’s microbiome. Maintaining a healthy microbiome could also help prevent many diseases.
So by all means, don’t stop brushing your teeth or washing your hands — this helps control bacteria that could harm you — but do remember that not all bacteria are harmful. One day, an infusion of bacteria might just cure your illness.
Dairy foods have played a role in human diets for thousands of years. More than one kid—whether millennia ago on the Mesopotamian plains or today in an American suburb—has been told to drink their milk to grow strong. This is because milk and other dairy products contain vitamins and minerals that are essential for a healthy body, including healthy teeth and gums. In honor of National Dairy Month in June, here are four ways dairy boosts your oral health:
Dental-friendly vitamins, minerals and proteins. Dairy products are an excellent source of many vitamins and minerals that are important for good dental health. They are packed with calcium and phosphorus, two minerals that work together to strengthen tooth enamel. In addition to the vitamins they contain naturally, milk and yogurt are fortified with vitamin D, which aids in calcium and phosphorus absorption; cheese contains a small amount of vitamin D naturally. What's more, dairy proteins have been shown to prevent or reduce the erosion of tooth enamel and strengthen the connective tissues that hold teeth in place.
Lactose: a more tooth-friendly sugar. Sugars like sucrose or high fructose corn syrup, which are routinely added to processed foods, are a primary trigger for tooth decay. This is because certain oral bacteria consume sugar, producing acid as a by-product. The acid weakens tooth enamel, eventually resulting in cavities. Dairy products—at least those without added sugar—are naturally low in sugar, and the sugar they contain, lactose, results in less acid production than other common sugars.
The decay-busting power of cheese. We know that high acidity in the mouth is a major factor in decay development. But cheese is low in acidity, and a quick bite of it right after eating a sugary snack could help raise the mouth's pH out of the danger zone. Cheeses are also rich in calcium, which could help preserve that important mineral's balance in tooth enamel.
Dairy for gum health. A study published in the Journal of Periodontology found that people who regularly consumed dairy products had a lower incidence of gum disease than those who did not. And since gum health is related to the overall health, it's important to do all we can to prevent and manage gum disease.
For those who cannot or choose not to consume dairy products, there are other foods that supply calcium naturally, such as beans, nuts and leafy greens—and many other foods are fortified with calcium, vitamin D and other nutrients. It may be wise to take a multivitamin or calcium with vitamin D as a supplement as well.
