Does the word “vitamin” make you think of a capsule that comes from a bottle… one that you’re supposed to take every day to improve your health? If so, it shows the effectiveness of the marketing strategy used by the vitamin and dietary supplement industry — a business that’s valued at $25 billion annually. The other definition, of course, is a substance that your body requires (in small amounts) to control normal metabolic functions and sustain life. It’s often assumed that taking vitamins in pill form can help you be healthier. But is that assertion really backed up by evidence?
It’s true that if your body is severely lacking in any of the 13 vitamins, you could be at risk for developing a disease related to vitamin deficiency: scurvy or pellagra, for example. Moreover, several vitamins (notably vitamins C and E, and beta carotene, a precursor to vitamin A) are also antioxidants; these are molecules that can protect our cells (and our genetic material) from damage caused by toxins in the environment and metabolic processes within our bodies.
Fruits and vegetables are rich in vitamins A and C, and vitamin E is found in vegetable oils. That’s one of the reasons why nutritionists and health-care providers stress the importance of a well-balanced diet, including plenty of plant-based foods. Many studies have shown that people who eat lots of vegetables and fruits have lower incidences of heart disease, cancer, and other chronic health problems.
You can also buy substances marketed as antioxidants and nutritional supplements in pill form. But contrary to what you might expect, in that form they don’t seem to have the same protective effect on the body. Scientists still aren’t sure why this is so, but it may have to do with the presence of many other biologically active compounds in vegetables and fruits. In fact, there is solid evidence that taking too many vitamins or supplements can be dangerous to your health.
We’re certainly not saying it’s of no use to take vitamins or nutritional supplements — especially if a deficiency is known to exist. If an individual isn’t getting enough vitamin D because they avoid exposure to sunlight, for example, then it makes sense to take a supplemental dose. But we need to remember that a supplement in pill form isn’t a substitute for a balanced diet — and taking unneeded supplements, or excessive doses, can lead to problems. Like it or not, there are few shortcuts on the road to good health.

Once upon a time, a well-known Hollywood actress might have hired a private eye to keep unflattering pictures from appearing in the media. Today, that’s no longer the case. Take timeless beauty Demi Moore: In a widely circulated set of photos, her gap-toothed grin showed she was actually missing one of her front teeth!
It turns out the actress released the pictures herself, as she live-tweeted the tooth replacement procedure from her dentist’s office. Moore later explained that the tooth fell out suddenly as she was sitting at her desk.
Celebrities are just like regular folks… except they have more followers on twitter. So we’re happy when they show us that no matter how bad a dental problem may seem, there’s almost always a way to regain a gorgeous-looking smile. We’re not sure exactly how Demi’s dentist chose to restore the damaged tooth — but depending on the individual circumstances, modern dentistry offers a number of ways to close the gap.
A crown (or cap) is a replacement for the entire visible area of the tooth. It may be needed due to accident or trauma, or as a follow-up to root canal therapy. Placing a crown usually requires more than one office visit. First, the tooth is prepared by removing any decay and shaping it, and a precise model is made of the bite. Next, the permanent crown is custom-made in a dental laboratory; this is placed during a subsequent visit. Advances in technology, however, have made it possible in some instances to deliver the permanent crown in a single office visit. If the tooth still has a healthy root structure, a crown is usually a viable option — even when most of the visible part is gone.
What if the entire tooth, including the roots, are missing? Then your replacement options could include bridgework or a dental implant. A fixed bridge is a series of crowns joined together as one unit. The teeth on either side of the gap are prepared just as they would be for crowns, and the bridge (including a replacement for the missing tooth in the middle) is attached. Bridges have been used successfully for many years, but they have a drawback: They require enamel to be removed from the healthy teeth on either side of the gap, which could lead to a greater chance of decay, gum disease, or a root canal in the future.
The optimal solution, however, might be a dental implant. With this remarkable technology, the replacement tooth is solidly anchored into the jaw via a screw-shaped post made of titanium — a metal which actually becomes fused with the living bone tissue. A custom-made, lifelike crown is then securely attached to the metal implant. Dental implants are the most successful tooth-replacement procedure; they help preserve bone quality in the jaw — and with regular care, they can last a lifetime.

Q: I’ve never heard these terms used in dentistry. What are they?
A: In the decorative arts, an inlay refers to a small piece of distinctive material that’s set into a larger matrix: a mother of pearl accent worked into the lid of a wooden box, for example. In dentistry, it means something similar: a filling (or restoration) that’s fabricated in a dental laboratory, and then set into a tooth in an area that has been damaged or lost.
Q: What’s the difference between inlays and onlays?
A: An inlay is made to fit in between the cusps (small points or ridges) of a back tooth (molar or premolar), and it covers only a small region of the biting surface of the tooth. If the restoration covers one or more of the cusps, it’s an onlay.
Q: Why would I need to have one of these restorations?
A: When a tooth has suffered damage (from decay or trauma, for example), and the affected area is too large to fill with a simple filling — but not large enough to need a full crown (cap) — then an inlay or onlay may be just right. Both of these procedures are considered “indirect fillings,” because the restoration itself is custom-fabricated in a laboratory and then bonded to the tooth in the dental office.
Q: What is the procedure for getting an inlay or onlay?
A: It’s similar to having a crown placed, in that it typically takes more than one office visit — yet an inlay or onlay involves less removal of tooth structure than a crown would require. On the first visit, after the area has been anesthetized (usually with a numbing shot), any decay is removed, and the tooth is shaped to receive the restoration. Next, a model of the tooth is made (either with putty or in digital form), and the tooth receives a temporary filling. The laboratory uses this model to create the actual inlay or onlay, which may take a few days; it is then permanently attached to the tooth on a second visit to the office. However, with today’s advances in CAD/CAM (computer aided design/ manufacturing) technology, some inlays or onlays can be made in the office and placed in the same visit.
Q: What else do I need to know about these tooth restorations?
A: Both inlays and onlays are strong and long-lasting restorations that need no more care than you would normally give your teeth: namely, regular brushing and flossing, and periodic checkups at our office. But because they don’t require the removal of a great deal of natural tooth material, they are considered relatively conservative treatments. After a thorough dental examination, we can recommend the type of tooth restoration that’s most appropriate in your individual circumstances.
