What Are the Choices for Replacing Old CERAC?

Question

I had multiple fillings replaced with CERAC 8 to 10 years ago and now have gaps and decay. My current dentist (who does not do chair side ceramic) recommends 8 crowns. I do not wish to compromise this significant amount of natural tooth material. Are there alternatives? Can ceramics be replaced and are newer CERAC type processes more precise? Can veneers be utilized? Thank you!

This mostly depends on how large the restorations/cavities are at this point. If there is compromised weakened tooth structure that may fracture, then crowns are recommended.

	Why did you get cavities under the old ones? Poor fit? Poor cementing/bonding? material failure?

	I don't like Cerec because it limits the materials that can be used and the dentist feels obligated to used it because they have it. You may be better served with the good old trusty porcelain fused to metal crowns which Cerec cannot do. Or maybe you can even get just a normal resin filling.

	Good luck

The new omnicam by CEREC is now out which I have been using for 3 months very nice, new lava crowns are another options. In most cases from your description don't be worried about loosing tooth structure remove the tooth decay and restore the tooth with composite filling, crown, or CEREC good luck

WIthout an exam and xrays I cannot tell you anything definitve. Yes cerecs can be replaced and there are stronger materials available today (EMAX) than 8 years ago. But the material used 8 years ago should still be holding up in most cases. This sounds more like a case of poor fitting restorations or inadequate home care or a combination leading to recurrent decay. Whether teeth need crowns now depends on how much solid tooth structure remains on a tooth by tooth basis.

This question cannot be properly answered without seeing photos and X-rays. Why did the original Cerec storations fail?
