What type of crown is the best?

I have had a silver filling on a back molar for over 30 years. Just recently the left, bottom section has cracked. My dentist says that I need a crown. I’m trying to decide between, CEREC, all-porcelain, gold, or porcelain-fused-to-gold. I don’t know much about the pros or cons or which is best for my situation. I’ve heard that CEREC crowns are very unlikely to break. I did seek another opinion and that dentist recommended a gold crown.

What concerns me most is the amount of healthy tooth that will need to be removed. Will that damage the other teeth around the molar? Also, do you know how long the crown will last? The dentist that I went to for a second opinion said that a gold crown will last for over 20 years, while porcelain is between 10 and 15 years or so. I guess I’m leaning toward the CEREC since it only takes one day. Also, if I choose CEREC I won’t need a temporary crown.

When a crown is being placed on a molar that is not visible when you’re talking or laughing, then appearance may not be an issue. This means that the gold crown will hold up the best over time and requires the least amount of tooth reduction. It is also the least obtrusive on the surrounding teeth and it is the strongest of all the crowns you have mentioned.

If appearance is a priority to you, than all-porcelain crowns are the most natural-looking. They may be the least strong but if the tooth is visible, it looks the best. Porcelain-fused-to-gold looks nice too but does require more removal of your tooth. This is due to the fit of the porcelain which doesn’t fit like all gold does. Any crown that contains porcelain may be abrasive to other teeth and may cause them to wear down.

I hope this information is helpful in your decision making process.

Can a tooth be saved from root resorption?


It has been a long time since I visited the dentist. In fact, it has probably been five years now or so. Although, two years ago I had some x-rays done and the dentist made a treatment plan. I just didn’t trust his recommendations and frankly couldn’t afford it. So when I went back to the dentist this month I anticipated there to be a lot of problems. The dentist filled a couple of cavities and then while trying to do a root canal treatment on one of my upper molars, he said I had root resorption. Apparently this wasn’t visible from the x-ray. He had originally thought that I just had a cavity located very close to the root. He says the tooth cannot be saved. Then, he is recommending a tooth extraction and having a dental implant placed.

Do you know if it was absolutely necessary to have the tooth pulled? Or was the endodontist forced to pull it because the root canal treatment was already in progress?

With root resorption, it all depends on where it is located. If it was at the end of the root, then it may have been caused from an infection. In this case it may have still been possible to salvage the tooth. Although, from what you have described it sounds like the resorption was located on the side of the root. If this was indeed the case, then the tooth would need to be extracted because there really is not a way to treat it effectively.
