Restore Broken or Cracked Teeth – Without the Unsightly Black Lines – with Metal-Free Porcelain Crowns from Columbus Dental Care, Serving Greater Nashua with Offices in Hudson NH.

Crowns, or caps, are used to restore broken or cracked teeth. For many decades, the standard in dentistry for crown and bridge restoration materials was PFM (Porcelain-Fused-to-Metal). The framework for the dental crown was produced in metal and then covered with a porcelain layer.

Unfortunately, the PFM method results in a “ring” of metal at the edges of the porcelain material that is nearly always visible.

With the evolution of all ceramic materials and their higher aesthetic qualities, dental patients have options. A metal-free framework beneath the porcelain makes the final restoration extremely natural looking, and eliminates the ugly black lines you may have seen at the gum line on older crowns.

E4D Single-Appointment Cosmetic Dental Care

Most dental restorations require more than one visit to the dentist. On the first visit, you get an injection of anesthesia, your tooth is prepared, an impression taken, and a temporary restoration put on your tooth. During a second visit a couple of weeks later, you get another injection, have the temporary taken off (if it hasn't fallen off already), and have a permanent crown put on.

Now, instead of going through all that hassle, you can get natural-looking metal-free all-ceramic crowns in just one visit to Columbus Dental Care.

The most advanced technology for the fabrication of all ceramic dental restorations is the E4D chairside laser-enhanced CAD/CAM system at Columbus Dental Care. Using the E4D system, Dr. Joe Columbus can give you permanent, all-ceramic crowns with fewer injections, less drilling, less hassle, and less time for dental care taken from your already hectic schedule. With E4D, the procedure is done in a single appointment, start to finish.

Safer, Healthier, Better-Looking Dental Materials

Years ago, dentists had few options to repair decayed and damaged teeth, other than to use amalgam, gold, and other metals. Now, Dr. Joe uses strong, tooth-colored ceramic materials to restore your teeth to their natural strength, beauty, and function, perfectly fit using the E4D system.


The new porcelain materials closely match the composition of your natural tooth structure. This means that when you eat hot food and then drink something cold, the restoration and tooth expand and contract at almost equal rates - your tooth does not crack, and you can go on enjoying your evening. The materials are also chemically bonded to your tooth, so Dr. Joe can save as much healthy tooth tissue as possible while providing you with a dental restoration that strengthens your tooth.
