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.
The month of May has been designated “Better Speech & Hearing Month” by the American Speech-Language-Hearing Association. Why would this be of interest to dental professionals? Because teeth are vital for good speech, and missing teeth can make it very hard to speak properly.
Speech is all about sounds, and forming sounds correctly requires proper positioning of oral structures such as the lips, tongue and teeth. For example, there are some words that are almost impossible to pronounce correctly without touching your tongue to your teeth. In fact, one of the hardest words to say without teeth…is teeth!
Missing teeth can affect speech indirectly as well, by reducing self-confidence. People who are missing front teeth often develop the habit of talking behind their hand or mumbling to avoid revealing the gap in their smile. Not being able to speak clearly and confidently can affect not only your appearance, but also your job prospects and social life. So what can you do about missing teeth?
Dental implants are today’s preferred tooth-replacement method. Implants are small titanium posts that are inserted in the jaw bone beneath your gums. They serve as “roots” to hold realistic-looking prosthetic (artificial) teeth in place. Implants can be used to replace one tooth, a group of teeth, or an entire row of teeth (upper or lower). Sometimes a dental implant can be placed the same day a failing tooth is removed so that you won’t need a second surgical procedure.
The healthy natural teeth on either side of the gap can also be used to support one or more replacement teeth. This method, called bridgework, can be used to replace a single tooth or several teeth in a row. Another option is removable dentures, which do not stay in the mouth all the time.
Each of these options has its benefits and risks. We’d be happy to discuss all of them in detail and help you decide which would be best in your own situation.

Porcelain veneers are one of the best ways to transform your teeth’s appearance with only a small amount of tooth preparation. But even that small amount could leave a veneered tooth permanently altered.
As the name implies, veneers are thin layers of custom-designed porcelain bonded to the outside of a tooth to cover defects. They’re usually ideal for minor chipping, staining or even slight tooth misalignments. But although they’re thin—often just a millimeter or so in thickness—they can still make a tooth appear or feel bulky.
To reduce this extra width, we usually need to remove some of the tooth’s surface enamel. Since enamel doesn’t replenish itself, this alteration could mean the tooth will require a restoration from then on.
But now, you may be able to take advantage of new advances in this popular restoration: No-Prep or Minimal Prep veneers that involve little to no tooth alteration. In most cases they’re simply bonded to the teeth with only slight enamel reshaping.
Because of their ultra-thinness, No-Prep veneers (usually between 0.3 to 0.5 mm, as thin as a contact lens) are bonded directly to teeth that are practically untouched beforehand. A Minimal Prep veneer usually requires only enamel reshaping with an abrasive tool before it’s placed. And unlike traditional veneers, they can often be removed if needed to return the teeth to their original form without another restoration.
These new veneers are best for people with small teeth, often from wear due to teeth grinding, narrow smiles (the side teeth aren’t visible while smiling), or slightly misshapen teeth like underdeveloped teeth that can appear peg-shaped. But people with oversized teeth, some malocclusions (bad bites) or similar dental situations may still require enamel removal to avoid bulkiness even with ultra-thin veneers.
If you don’t have those kinds of issues and your teeth are reasonably healthy, we can apply No-Prep or Minimal Prep veneers in as few as two appointments. The result could be life-changing as you gain a new smile you’re more than happy to share.
