My dentist says a zirconium crown is as good as a gold crown. What is the difference?

My dentist says a zirconium crown is as good as a gold crown. What is the difference?

Gold lasts longer: Gold requires less tooth removal, is soft and forgiving on the opposing teeth, and the margins are less likely to decay. I regularly see nice gold crowns that are older than i am; a zirconia crown will simply not last that long. Zirconia is a fantastic super hard material, but requires a lot of tooth removal. It also is very abrasive once the glaze rubs off; it will wear down your opposing teeth. ...Read more

What are the benefits (and not) of having a zirconium dental crown as compared to a high noble porcelin fused to metal crown?

3 Main Advantages: Strength, Aesthetics and Retention of the existing tooth. These are strong crowns have an attractive translucent color which blends in well with the other teeth. Minimal preparation is required which means more of the original tooth is preserved. Porcelain to High Noble Metal is also strong when the tooth is reduced enough (more than zirconia). ...Read more

Hello docs. I was wondering can xrays show decay in teeth with zirconium or porcelain crowns?

X-rays can't: Agree with Dr. Bruce Pope 100%. X-rays can't detect decay under a crown so until the crown comes off it is impossible to know how extensive the damage is. ...Read more

Zirconium dental implants. How common is it used now. Is there any advantages or benefits over titanium implants. Cons & pros please. Thanks.

Zirconium dental implants. How common is it used now. Is there any advantages or benefits over titanium implants.  Cons & pros please. Thanks.

Dental implants: A majority of the dental implants placed are titanium. They are highly successful with many years use ; many studies, much lower in cost ; have many restorative options. Zirconia implants are newer, fewer studies on success, lesser restorative options. However they can be more aesthetic in certain anterior(front) situations. Let your dentist/oral surgeon chose what they feel will be best for you. ...Read more

Thoughts about dental bridge made of Zirconium. Any issues cons /pros please. My 4 unit bridge (#11 -14) made of Porcelain/PFM broke off 2 times. ?

Thoughts about  dental bridge made of  Zirconium. Any issues  cons /pros please. My 4 unit bridge (#11 -14) made of Porcelain/PFM broke off 2 times. ?

Etiology: Must determine reason for failure. Did ceramic break or did bridge come off teeth ? #11 - 14 is a long span if only supported by those 2 teeth. #11 does double duty as it is a corner transition tooth and gets loaded in many directions. Overloading the bite and insufficient tooth to support this are most common causes. See a Prosthodontist for opinion. Consider 2 implants #12,13. Good Luck. ...Read more

2 Four unit bridges (#11 -14) Porcelain & PFM, the  porcelain on false tooth broke off 2 times. Any thoughts about  using 100%  Zirconium made bridge?

Implant consultation: If possible speak to the dentist about implants and single crowns, which may be easier to maintain. Have the dentist check the bite to make sure there is adequate room, A zirconia bridge may be stronger but if the room is inadequate there still may be a problem. ...Read more

All solid zirconium that support span of 4 unit bridge covering teeth 11 to 14 broke after 10 weeks. Previous porc bridge also broken. Causes/options?

All solid zirconium that support span of 4 unit bridge covering teeth 11 to 14 broke after 10 weeks. Previous porc bridge also broken. Causes/options?

Dynamic forces: Many factors can lead to this, but most important are the support base and the bite. This is a long span to cover when starting with the canine, but do not expect the zirconium to fx. Likely clenching/grinding without occlusal guard/compliance . See the expert in reconstruction - Prosthodontist. Consider 2 crowns and 2 implants (12,13) with crowns and bite correction (lower arch). good luck. ...Read more

Feedback or cons/ bros on using all solid zirconium to support the length/span of 4 unit bridge covering teeth 11to14. Prevosiue porc bridge broken?

Feedback or cons/ bros on using all solid zirconium to support the length/span of 4 unit  bridge covering teeth 11to14. Prevosiue porc bridge broken?

Very strong: An all zirconium bridge contains no metal and is very strong. Another bridge option is a porcelain over metal bridge, which you may already have that has broken. Other options for replacing missing teeth would be implant(s) to replace the missing teeth or a partial denture. However, we are big proponents for all-zirconium bridges that are more biocompatible with the tissue than metal based bridges ...Read more

What could cause an alignment problem after crowning?

Size: Crowns are made for the most part in freehand, so during the cementation process, adjustments are normal. Additionally the marking paper is not necessarily more accurate than what you feel. I suggest you tell your dentist your concerns and maybe more adjustment is needed on your crown. It's common for a crown to need an additional adjustment after cementation. ...Read more

How long does he have to wait before he can eat again after a crowning?

How long does he have to wait before he can eat again after a crowning?

A few hours: If it's the first step of getting a crown, then don't eat any food until all of the numbness is gone. In addition, some temporary cements take a few hours to set completely. If it;s the second step where the permanent crown is fitted, sometimes you are numb, sometimes not. Again, don't chew if there is any numbness. Otherwise the final cement hardens very quickly. ...Read more

Is there pain relief for crowning in birth?

Is there pain relief for crowning in birth?

Sure: Delivery is the ultimate pain relief but prior to delivery, an epidural is useful for pain relief. If labor is too quick and/or an epidural is not available; a pudendal block (injection) can be placed by your OB and this helps tremendously, especially with first time moms who are experiencing lots of pain. Discuss your options with your OB before labor. Take care. ...Read more
