Crowns, Bridges & Veneers

Dentistry is an art as well as a science; dental crowns offer a perfect example of this. A dental crown or “cap” is a covering that fits over a damaged, decayed or unattractive tooth. It can even replace a tooth entirely as part of dental bridgework.

A crown completely covers a tooth above the gum line. This is in contrast to a dental veneer, which only covers a tooth’s front surface and needs natural tooth structure to support it. Therefore, if a tooth is missing a significant amount of structure above the gum line, a crown would be the restoration of choice.

Crowns strengthen damaged teeth, allowing them to function normally again. When crafted from today’s high-tech porcelains (dental ceramics), crowns are virtually indistinguishable from natural teeth. They can even be designed to improve upon a tooth’s original appearance.

There are other materials besides porcelain that we can use to make dental crowns, depending on what qualities are most important. For durability, cast gold can’t be beat. However, this is not always the most aesthetic choice — especially towards the front of the mouth. Other possibilities include porcelain-fused-to-metal crowns (PFM), which have a metal interior for strength and a porcelain exterior for a more natural appearance, and all-porcelain crowns with zirconia, representing the strongest ceramic. We would be happy to discuss the pros and cons of these various options with you.

Creating a Bridge

Dental Bridgework can also be used to create a lifelike replacement for a missing tooth. This is done with bridgework, which spans the space of the missing tooth and requires at least three crowns. Two of those crowns will be placed over healthy teeth on either side of the missing tooth; these healthy teeth are referred to as abutment teeth. The two crowned abutment teeth become supports for a third crown placed in between them; that third crown is referred to as a pontic. If more than one tooth is missing, more crowns will be needed to bridge the gap in between the abutment teeth.

The number of abutment teeth necessary to replace missing teeth is influenced by the number of missing teeth, the size and length of the abutment tooth roots, the amount of bone support each abutment tooth has, as well as where in the mouth the missing tooth is located. For example, if you have three missing teeth, four abutment teeth may be necessary, thereby creating a seven-tooth bridge. Engineering and designing of the bridge requires an understanding of how to replace teeth, as well as the biology of the supporting gum and bone tissue.

Caring for Your Crowns & Bridgework

Crowns and bridgework require the same conscientious care as your natural teeth. Be sure to brush and floss between all of your teeth — restored and natural — every day to reduce the buildup of dental plaque. When you have crowns, it is even more important to maintain your regular schedule of cleanings at the dental office. Avoid using your teeth as tools (to open packages, for example). If you have a grinding habit, wearing a nightguard would be a good idea to protect your teeth and your investment.

"I have been very fortunate to have been a patient of Dr. Edward Yates since 2004. He has taken exceptional care of me and my family, particularly providing my children with the most amazing smiles! His pain management is amazing, I have never experienced any discomfort during the root canals and crowns that he has performed for me. His technology is outstanding, crowns are completed in one visit. Dr. Yates and his staff are outstanding!"

"Best cleaning I have ever had was by Johanna. Very thorough. Would definitely recommend. I'm moving an hour away but will only use this office for my dental work from now on. Very clean and friendly."
