Question:
Hi. I have two porcelain crowns on my front teeth. They have been on for close to two years and one of them has never really felt right. It was always sensitive to pressure, hot and cold, etc.... My dentist who appears to be highly qualified told me that it would fade.

Recently, I have been having interspersed periods of a throbbing dull pain directly under the crown. It gets quite uncomfortable at times and has me concerned that there may be a problem. My dentist used the best of everything including empress crowns and resin cements.

What do you think the problem could be? ...Visitor from VA

Answer:
Empress and most porcelain crowns have many benefits along with their ability to create a natural translucent beautiful restoration. They oftentimes need less tooth reduction and still are very strong.

The description of your concern has many possibilites. The teeth may have been traumatized due to old fillings, heat from the preperation, opening of the dental tubes (the inner hard material of the tooth which is found closest to the nerve) during the acid-etching bonding with the resin cement.

This type of truama is common and will lead to a hot and cold sensitive tooth which will often desensitize in a few days to two months.

You may also have had the tooth just a little big on the biting surface which would create a bruise by the teeth always hitting themselves. This would have been something which would have occurred quickly and would often be a dull throb to touch.

Another reason could be that the gingvae (gum) tissue could have been irritated due to a foreign body such as a popcorn husk or some of the cement from the crown.

It would seem that the tooth at this time has not been able to recover from this trauma and now the treatment may need to be a root canal. This could be done through the crowns and the access hole covered with a composite filling.
