Have you ever been told you need a "crown" for your teeth? Are you confused why you may need a crown for your tooth? There are many reasons why a crown be necessary but the dentist is likely recommending a crown for one(or more) of the following reasons...

1. Crack in the tooth(may or may not cause sensitivity). Sensitivity can in the form of hot/cold and/or bite sensitivity.

2. Tooth decay(cavity) around a tooth. Large decay around an untouched tooth or decay around an existing filling can both be reasons. If the tooth has never been worked on..then it will depend on how and where the decay is.

3. Tooth has been root canal treated. More common in back teeth but also seen on front teeth. All back teeth that have needed a root canal ABSOLUTELY need a crown!

4. Severely malpositioned, misaligned or discolored tooth. These are obvious more "esthetic" reasons vs the reasons above which are more "functional reasons".

4. Tooth that has large filling on a patient that grinds their teeth at night or clenches their teeth during the day. Teeth with very large fillings are much more likely to fracture.

5. An existing crown that has fractured(such as the porcelain) or has new tooth decay around the crown.

While these are only a couple reasons why we recommend crowns, its important to ask your dentist what a crown is, why you need a crown, the benefits of a crown and certainly the consequences of NOT getting a crown.

 

Happy Crowning!

Question: Hi there, I am a 51 year old woman in pretty good health. In 2004 I had my 4 front teeth removed and porcelain crowns put in. It has become apparent that they were not sealed well enough, so over time decay has set in behind the crowns. They must now be removed and new ones inserted. My financial situation has changed considerably since then and the insurance I have now only covers porcelain infused over metal crowns. It would cost me another $600 per tooth if I want porcelain. I had never heard of these other ones so I would like your input on the aesthetics and longevity of the porcelain infused over metal.Thank you for your time and opinion

 

Answer: The porcelain fused to metal(PFM) crowns have been around much longer than all porcelain crowns. They are known for strength and I typically do these on back teeth. They do work well on front teeth but can be more challenging to make them look esthetic. I would talk with your dentist about doing the PFM crowns but it will be much more difficult to match the esthetics that you had with all porcelain crowns. I like the all porcelain better but if done correctly the PFM crown can be acceptable as well. My biggest concern is that if they are designed corrected or even if your gums even slightly recede, you can possibly see dark line or metal hue around where the gum has receded. If you have ever seen someone smile and you see a dark color or gray hue around the gum, it is likely it is PFM crown. With an all porcelain crown, even with recession it is not as visible. All porcelain is typically my choice, if and only if your bite will allow it.
