YouCanPutOnaGreatFacewithVeneersandCrowns

Smiling feels great and makes others feel good as well. But if you are self-conscious about exposing teeth that are showing imperfections or excessive wear, you may not be smiling as broadly as you should be. Fortunately, there are ways to correct the esthetic issues that might be holding you back. One involves covering the natural tooth partly or completely with a natural-looking but flawless “facade.”

Perhaps you've heard about dental veneers and crowns? Both can achieve similar, eye-pleasing results by changing the shape and color of your teeth and even helping to compensate for uneven spacing or alignment. And both are custom-designed for your teeth. So what's the difference and which is right for you?

One distinguishing feature is the amount of tooth each covers. A veneer is a wafer-thin layer of dental porcelain that bonds to the front of your tooth. A crown, also fashioned from dental porcelain, fits over and covers the entire existing tooth, like a hood, right down to the gum. With either approach, to ensure the best, most natural fit, some of the natural tooth structure must be reduced by a minimal amount. In the case of veneers, up to 1 mm of tooth enamel — about the thinness of a fingernail — is removed. Crowns are generally thicker than veneers, so in their case the removal of at least 2 mm of tooth is needed.

Another difference between veneers and crowns is the situations in which one might be more suitable than the other to achieve the desired results. For example, a crown may be necessary when too much tooth structure has been lost to decay or other problems, or for use on back teeth that have to withstand greater impact from biting and chewing. A dental professional can make a recommendation based on your goals, the condition of the tooth or teeth in question, and other factors.

Either way, both veneers and crowns are an excellent solution for a range of esthetic concerns — from poor tooth color/staining, chips and cracks, and excessive wear at the bottom of teeth (from bruxism, a term for teeth grinding) to making small teeth look larger, closing minor gaps between teeth, and making slight corrections in alignment.

ImplantOverdenturesaMarriageofOptionsforLowerJawToothReplacement

For well over a century, removable dentures have been the main treatment option for patients suffering from severe or total edentulism (loss of teeth). In recent years, however, the dental implant has been recognized as the best option because it can provide patients with permanent tooth replacement, and even more so as implant technology continues to advance.

But while permanent tooth replacement using implants offer more comfort and a better fit than dentures, they are more expensive, sometimes out of the financial reach of many patients. There is, however, one alternative for the lower jaw that blends the two options for tooth replacement into one. This alternative is known as an implant overdenture.

The implant overdenture begins just as a fixed dental implant would: we surgically implant two titanium posts into the lower jaw and allow them to fuse with the bone over time (thanks to the unique way that bone interacts with titanium). But rather than next affixing a porcelain crown to the post as we would with a dental implant, we would instead fashion a denture that fits over the two posts (hence the term overdenture). The overdenture has receiver sites that connect securely with the titanium posts to hold the overdenture in place. This ensures a snug fit with no slippage — resulting in better ability for the wearer to chew food and speak — and without the continuous need for dental adhesive. And just as with traditional dentures, you can remove the overdenture for cleaning.

It might also be an optimal solution for patients with severe issues involving bone loss or compromised teeth that make it difficult for them to support either a fixed prosthesis or a traditional removable denture.

This option does have some drawbacks: since it's still a removable denture, it can still move during meals and food can sometimes get underneath it, which can be annoying. Also, overdentures for the upper jaw require more than two implants because the upper bone is less dense; thus because of a greater number of implants, an upper overdenture is more costly than a lower one.

In the end, an implant overdenture to the lower jaw might be an optimal solution for you — financially and practically — to restore function from severe or total edentulism.
