Porcelain crown keeps falling out

I’ve had a porcelain crown for about a year and it has fallen out several times already. My dentist re-cements them in for free, but I’m wondering if they should be doing this. It is very inconvenient having to keep going back for appointments, even when they are free.

No, porcelain crowns should not be falling out, especially as much as yours has. It sounds to me like your dentist does not know how to do the bonding, and is just cementing them in.  There is also some trick to the parallelism of preparing the tooth, but if they are bonded properly, there doesn’t need to be a lot of retention in the design.

Your dentist may not be familiar with the bonding procedure. If he’s not, don’t pressure him to do it. It would be in your best interest to pay another dentist with a lot of experience with bonding than to either keep wasting your time having him re-cement it, or  force him into doing a procedure he isn’t qualified to do and having bigger problems result from it.

Cavities and Lumineers

Can you get Lumineers if you have a cavity on your front tooth?

You’ll need to get your cavities taken care of, but after that you can have veneers placed directly on top of the fillings. I don’t know if you’re mind is settled on Lumineers. I want you to be aware that they are just a brand of porcelain veneers and not unique onto themselves. In fact, many cosmetic dentists aren’t pleased with their quality.

However, if you are set on getting Lumineers, just be sure you go to an expert cosmetic dentist, like someone who is AACD accredited. Then you can be sure you’ll get a great smile no matter what brand you use.
