Implant-SupportedDenturesCouldContributetoBetterBoneHealth

For generations, dentures have helped people avoid the dire consequences of total teeth loss. Now, implant technology is making them even better.

Composed of life-like prosthetic teeth fixed within a plastic or resin gum-colored base, dentures are manufactured to fit an individual patient’s mouth for maximum fit, comfort and performance. But dentures also have a critical drawback—they can’t stop bone loss in the jaw.

Bone is constantly regenerating as older cells dissolve and then are replaced by newer cells. In the jawbone, the forces generated when we chew travel through the teeth to the bone and help stimulate this new cell growth. When teeth are missing, though, the bone doesn’t receive this stimulus and may not regenerate at a healthy rate, resulting in gradual bone loss.

Dentures can’t transmit this chewing stimulus to the bone. In fact, the pressure they produce as they rest on top of the gums may actually accelerate bone loss. Over time then, a denture’s once secure and comfortable fit becomes loose.

In the past, most patients with loose dentures have had them relined with new dental material to improve fit, or have new dentures created to conform to the changed contours of the jaws. But implant technology now offers another alternative.

Implants are in essence a tooth root replacement. Dentists surgically implant a titanium metal post directly into the jawbone that naturally attracts bone cells to grow and adhere to it over time (a process called osseointegration). This not only creates a secure and lasting hold, it can also stop or even reverse bone loss.

Most people know implants as single tooth replacements with a porcelain crown attached to the titanium post. But a few strategically placed implants can also support either removable or fixed dentures. Removable dentures (also called overdentures) usually need only 3 or 4 implants on the top jaw and 2 on the bottom jaw for support through built-in connectors in the dentures that attach to the implants. A fixed bridge may require 4-6 implants to which they are permanently attached.

There are pros and cons for each of these options and they’re both more expensive than traditional dentures. In the long run, though, implant-supported dentures could be more beneficial for your bone health and hold their fit longer.

FifthHarmonysCamilaCabelloChipsaToothbutConcertStillWorthIt

Everyone loves a concert where there's plenty of audience participation… until it starts to get out of hand.├é┬áRecently, 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.

LocalAnesthesiaisaKeyPartofPain-FreeDentalWork

We can easily take for granted the comfort we now experience when we undergo dental work. For much of human history that hasn't been the case.

Local anesthesia has been a major factor in the evolution of pain-free dentistry. The term refers to the numbing of nerve sensation in the tissues involved in a procedure. This type of anesthesia is usually applied in two ways: topical and injectable.

We apply topical anesthetic agents to the top layers of tissue using a cotton swab, adhesive patch or a spray. Topical agents are useful for increasing comfort during cleanings for patients with sensitive teeth or similar superficial procedures. Topical anesthesia is also used in conjunction with injections as a way to prevent feeling the minor prick of the needle. In essence, you shouldn't feel any pain or discomfort from beginning to end of your procedure.

Injectable anesthesia deadens pain at deeper levels of tissue. This makes it possible for us to perform more invasive procedures like tooth extraction or gum surgery without using general anesthesia. The latter form is a more intense undertaking: it renders you unconscious and may require assistance for lung and heart function.

Most important of all, subtracting pain sensation from the procedure helps relieve stress: first for you and ultimately for us. If we know you're comfortable, we can relax and concentrate on the work at hand. The procedure goes much more smoothly and efficiently.

Many people, though, have concerns about how long the numbness will linger after the procedure. This has been viewed in the past as an annoying inconvenience. But in recent years, dentists have become more adept at fine-tuning the agents they use as a way to reduce post-procedure numbness. There's also promising research on chemical agents that can quickly reverse the numbing effect after a procedure.

All in all, though, using local anesthesia broadens the range of dental work we can perform without putting you to sleep. More importantly, you'll be able to relax as we perform procedures that could improve your dental health for years to come.
