What is a dental crown?

A crown is a porcelain restoration which completely covers and supports a compromised tooth. It faithfully mimics natural tooth shape, size and color and preserves a failing tooth from further damage or extraction.

Crowns used to take weeks to get. How can one be made in a day?

Actually, the dentists at TLC Dentistry in Lexington, KY, make and place porcelain crowns in about two hours. They do the required imaging, enamel shaping, and design, manufacture and placement of your restoration all in the same treatment room.

Is the process uncomfortable?

No, it's actually more comfortable than traditional methods. Your dentist will shape your tooth to receive the crown, removing the decay and other damaged portions. This may require some local anesthetic to numb the tooth.

Beyond that, you'll barely notice the procedure. Oral impressions are taken with a digital instrument which is about the size and shape of a pen. That means no sticky putty and uncomfortable impression trays--just accurate and quick three-dimensional imaging delivered right to the dentist.

Also, because your crown will be ready quickly, you won't wear an awkward temporary crown. Instead, you'll wait in your dental chair as your the milling machine carves your crown from a solid block of porcelain. You can even watch it being made!

How does the milling machine know what to do?

That's where your dentist's expertise comes in. He'll use computer-aided design software to instruct the machine on the details of your restoration. Then, the fabrication takes only 15 to 20 minutes. When it's finished, the dentist does a final shading and polishing and then bonds your crown over your tooth. Typically, same-day crowns are a perfect fit will little to no adjustment.

Will my new crown last?

If you take care of it, you should enjoy it for at least ten years. Floss and brush it as you do your other teeth, and come to the office twice a year for your usual check-ups and professional cleanings. Crowns don't decay, but they can chip and loosen. So, don't chomp down on ice or use your teeth to open packages or bottles. Also, it's important to keep the margins of your crown free of toxic plaque and tartar, the causes of periodontal disease.

A “crown” or a “cap” is the term used to restore a decayed or broken tooth that needs to be completely encased to protect the tooth beneath it. A crown's dual purpose is to restore the tooth's form and function. Decades ago gold was the material of choice for a crown. What we ultimately choose depends on a particular crown's requirements with regard to the tooth's appearance and function, and to some extent what you want.

Gold: Gold crowns last the longest and wear the best (at about the same rate as natural teeth), but they are not used as frequently today, especially if they are visible in a person's smile. Gold crowns are made of cast gold, a technique that has been in use for over a hundred years. They can last for decades, and have been known to last 50 years or more. They tend to cost less per tooth than porcelain or other materials.

All-Porcelain: “All porcelain” crowns have a natural appearance and as technology improves they are gaining popularity. Dental porcelains are composed of ceramic substances that are variations of glass. This gives them their translucent, lifelike appearance — but it makes them brittle and subject to fracture. Therefore all-porcelain crowns may not be a good choice for back teeth because they frequently fail under the biting forces applied during chewing and especially adverse habits like tooth clenching or grinding. Porcelain crowns are made of material that doesn't wear. Consequently, it can cause excessive wear to the teeth they bite against.

Porcelain-Fused-to-Metal (PFM): PFM crowns have been in use for more than 40 years. They combine a substructure of gold or platinum for strength and have porcelain “facings” for the visible surfaces. In some ways they combine the best of both worlds, but they do have some problems; the metal can show through the porcelain, detracting from its life-like appearance. These crowns can have a functional lifespan of about 20 years or more.

New and Future Materials: Newer “pressed-ceramic” restorations and computer-milled ceramics have received good reviews for aesthetics and service. These new materials are being intensively researched. Initial results look good, but we'll have to see how they last over time.
