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.
So, you’ve just acquired an attractive restoration with dental implants. You may be thinking at least with these teeth you won’t have to worry about dental disease.
Think again. While the implants and their porcelain crowns are impervious to decay the surrounding gums and bone are still vulnerable to infection. In fact, you could be at risk for a specific type of periodontal (gum) disease called peri-implantitis (inflammation around the implant).
Bacterial plaque, the thin bio-film most responsible for gum disease, can build up on implant crowns just as it does on natural tooth surfaces. If it isn’t removed with daily brushing and flossing and regular dental cleanings the bacteria can trigger an infection in the gums.
Besides weakening gum tissues, gum disease can also cause bone loss, of critical importance to dental implants. An implant depends on the bone they’re inserted in to hold them in place. If the bone around an implant becomes infected it could begin to be lost or dissolve (resorb), which could lead to loss of the implant.
That’s why it’s critical to keep the natural tissue structures supporting your implants infection-free. Not only is daily hygiene a must, but your implants and any remaining natural teeth should undergo professional cleaning at least twice a year or more if your dentist recommends it.
Cleanings involving implants will also be a bit different from natural teeth. While the dental materials used in the crown and implant post are quite durable, regular cleaning instruments can scratch them. Although tiny, these scratches can become hiding places for bacteria and increase your risk of infection.
To avoid this, your hygienist will use instruments (known as scalers and curettes) usually made of plastics or resins rather than metal. The hygienist may still use metal instruments on your remaining natural teeth because their enamel can tolerate metal without becoming scratched creating a smoother surface.
While keeping implants clean can sometimes be a challenge, it’s not impossible. Implants on average have a long-term success rate above 95%. With both you and your dentist caring and maintaining these state-of-the-art restorations, you may be able to enjoy them for decades.
