Each part of the human body is an intricate wonder. Take your teeth, for example: they’re so woven into everyday life we don’t notice them, yet they each work seamlessly with the jaws and mouth so we can eat, speak and even smile.
Here, then, are a few facts to help you understand — and appreciate — these tiny, amazing wonders we call teeth.
Layer Upon Layer. Rather than one solid mass, teeth are composed of different layers of slightly different tissues each with a unique role in protecting and enabling a tooth to function. Innermost is the pulp filled with connective tissue encasing blood vessels and nerves that transmit sensations to the brain. The next layer out is the dentin, a bone-like material sensitive to touch and other stimuli, which also absorbs some of the forces generated when biting or chewing. The outermost layer is enamel, the hardest material in the body and the tooth’s first defense against infection and other dangers.
Front and Center. Teeth perform different functions depending on their type and location. Front teeth are our “onstage performers” — they help us to speak and enunciate words clearly and, of course, contribute to our smile. They’re also adept at cutting through food when it first enters our mouths.
The Support Team. In keeping with our theater analogy, back teeth are our “backstage crew”: they help support our facial height, provide balance for the jaws as we swallow and protect the front teeth from too much vertical force. They’re also able to crush food before we finally swallow, which aids in the digestive process.
Intended for a Lifetime. If you consider all the environmental factors our teeth face — acidic foods, biting forces and temperature swings to name a few — you then can appreciate their resiliency. Of course, teeth have their enemies: decay, infection and trauma. With daily brushing and flossing and at least a couple of visits a year to our office for cleanings and checkups, you can help thwart many of those enemies. With both our efforts we can make sure your teeth really do last a lifetime.
Repairing a decayed tooth may be as simple as removing the damaged tooth material and filling the void. Many filling materials can now match the color of a tooth, so the dental work is hardly noticeable.
Sometimes, though, the decay is too extensive or we've treated the tooth several times and it won't support another filling. If the tooth is still viable, we may be able to cover it with a custom crown.
Also known as a cap, a crown fits over and is securely affixed to the tooth with bonding material or cement. Crowns have been used for decades to restore teeth, but the materials they're made of have changed with time.
The original crowns were made of metal, usually gold or silver. They were strong and could hold up well to the daily forces produced by chewing or biting. They did, however, visually stand out and came to be regarded as unattractive. There were porcelain materials available that could closely mimic the life-likeness of teeth, but they could be weak and brittle.
Dentists came up with a hybrid crown that could supply strength as well as an attractive appearance. These were composed of two parts: an inner metal frame for strength overlaid with porcelain for appearance. These fused crowns were the most popular until the mid-2000s.
About that time, newer forms of porcelain came on the market that were not only attractive, but also durable. Although caution should still be taken when biting something hard, they've proven to stand up well to biting forces. Fused porcelain to metal is still in use, but usually for back teeth where biting forces are higher and the crown won't be as noticeable as on front teeth.
Crowns can also address cosmetic issues with chipped, fractured or excessively worn teeth. But with any crown you should be aware that much of the original tooth material must be removed to accommodate the fit. The altered tooth will require a crown or other restoration from then on. Crowns must also be custom-made by a dental technician in a process that can take weeks.
Still, the process can be well worth it. With proper care and maintenance, a crown could serve you and your smile well for many years to come.

Are you reluctant to have your orthodontic problems resolved because you want to avoid wearing conspicuous metallic brackets and wires? If so, a dentist at More Smiles of Beverly in Chicago, IL, might be able to straighten your smile and improve its appearance discreetly using Invisalign braces instead. One Invisalign consultation could be the beginning of a whole smile makeover.
Why You Want to “Get Things Straight” with Your Smile
There are both cosmetic and functional reasons why you would want to straighten out teeth that are crowded, misaligned, and crooked. These common smile imperfections are easy to notice—people often have a tendency to look at your mouth when you talk, which can be distracting and demotivating if there are cosmetic issues. Also, when there are gaps due to small or misaligned teeth, it can also cause problems with food getting stuck between the teeth.
Invisalign: The Discreet Choice
Many patients avoid necessary orthodontic treatment because they are afraid of having to wear metal braces. A discreet option is not only preferable but required if you have a very busy lifestyle. If concerns about your appearance have caused you to avoid straightening out your smile, talk to your Chicago dentist about Invisalign. The treatment requires the use of custom-made plastic clear braces that you must wear for the majority of your day. Besides being discreet, Invisalign also allows you the comfort of being able to brush, floss, and eat normally.
Word to the Wise: Wear Your Retainer
When your smile is straightened out, you’ll have to do maintenance to keep the new position of your teeth. So, after you’ve gone through the Invisalign treatment period, which can take anywhere from six to 12 months, it’s important to wear your retainer every night thereafter. Though your teeth are now in an optimal position, there’s always a chance for them to shift back. The retainer will help maintain the appearance of your new smile.
Go in for a Consultation
At your initial orthodontic consultation, your dentist will help you determine if Invisalign will be your best bet. Call (773) 980-8900 today to schedule your visit with Dr. Ademola Adekola Jr. at More Smiles of Beverly in Chicago, IL.
X-rays are an important diagnostic tool in dentistry because of their ability to penetrate and pass through body tissues. Because they penetrate at different speeds depending on tissue density (shorter and thus darker on exposed film for soft tissues, longer and lighter for hard tissues like bone or teeth), we’re able to detect decay which appear as dark areas on x-ray film.
Without x-rays, the early detection and diagnosis of dental problems would be quite difficult. But despite its obvious benefits, it’s still a form of released energy that exposes patients to a certain amount of radiation. Since the potential health risk from radiation depends on the amount released (the dosage) and for how long and often a person is exposed, we must determine if the dosage and frequency from dental x-rays is a cause for concern.
It’s a common misconception to view any radiation exposure as dangerous. The truth is, however, we’re all exposed daily to radiation from the natural environment — about 2 to 4.5 millisieverts (the dosage measurement for radiation exposure) a year, or about 10 microsieverts (one-thousandth of a millisievert) every day.
In comparison, radiation exposure from routine dental x-rays is a fraction of this if measured over time. A set of four bitewing images of the back teeth produces 4 microsieverts of radiation, less than half the average daily exposure. One of the most comprehensive x-ray sets, a full mouth series of 18-20 images using “D” speed film, results in an exposure of 85 microsieverts, equaling about a week of normal radiation exposure.
These thoroughly researched rates help demonstrate that regular dental x-rays are relatively safe. What’s more, x-ray technology has continued to advance since first used in the mid-20th Century. With innovations in film and digital processing, today’s equipment produces only 80% of the radiation exposure of earlier machines. In effect, we’ve increased our capabilities to more accurately detect and diagnose issues through x-rays, while lowering the amount of radiation exposure.
Of course, a person’s annual exposure rate may differ from others. If you have concerns for yourself or your family about x-ray radiation exposure, please feel free to discuss this with us. Our primary goal is to improve your oral health without undue risk to your health in general.

Some people are lucky — they never seem to have a mishap, dental or otherwise. But for the rest of us, accidents just happen sometimes. Take actor Jamie Foxx, for example. A few years ago, he actually had a dentist intentionally chip one of his teeth so he could portray a homeless man more realistically. But recently, he got a chipped tooth in the more conventional way… well, conventional in Hollywood, anyway. It happened while he was shooting the movie Sleepless with co-star Michelle Monaghan.
“Yeah, we were doing a scene and somehow the action cue got thrown off or I wasn't looking,” he told an interviewer. “But boom! She comes down the pike. And I could tell because all this right here [my teeth] are fake. So as soon as that hit, I could taste the little chalkiness, but we kept rolling.” Ouch! So what's the best way to repair a chipped tooth? The answer it: it all depends…
For natural teeth that have only a small chip or minor crack, cosmetic bonding is a quick and relatively easy solution. In this procedure, a tooth-colored composite resin, made of a plastic matrix with inorganic glass fillers, is applied directly to the tooth's surface and then hardened or “cured” by a special light. Bonding offers a good color match, but isn't recommended if a large portion of the tooth structure is missing. It's also less permanent than other types of restoration, but may last up to 10 years.
When more of the tooth is missing, a crown or dental veneer may be a better answer. Veneers are super strong, wafer-thin coverings that are placed over the entire front surface of the tooth. They are made in a lab from a model of your teeth, and applied in a separate procedure that may involve removal of some natural tooth material. They can cover moderate chips or cracks, and even correct problems with tooth color or spacing.
A crown is the next step up: It's a replacement for the entire visible portion of the tooth, and may be needed when there's extensive damage. Like veneers, crowns (or caps) are made from models of your bite, and require more than one office visit to place; sometimes a root canal may also be needed to save the natural tooth. However, crowns are strong, natural looking, and can last many years.
But what about teeth like Jamie's, which have already been restored? That's a little more complicated than repairing a natural tooth. If the chip is small, it may be possible to smooth it off with standard dental tools. Sometimes, bonding material can be applied, but it may not bond as well with a restoration as it will with a natural tooth; plus, the repaired restoration may not last as long as it should. That's why, in many cases, we will advise that the entire restoration be replaced — it's often the most predictable and long-lasting solution.
Oh, and one more piece of advice: Get a custom-made mouthguard — and use it! This relatively inexpensive device, made in our office from a model of your own teeth, can save you from a serious mishap… whether you're doing Hollywood action scenes, playing sports or just riding a bike. It's the best way to protect your smile from whatever's coming at it!
