Microleakage of porcelain veneers causing bluish tint at gum line? (photo)

Question

I had 10 porcelain veneers placed 1 month ago. 7 of them look great but 2 of the teeth are showing a bluish tint under the veneers close to the gum line and 1 tooth is showing a bluish border around the side edge of the tooth. Some of my gums were bleeding quite a bit during the prep appointment. Will the 3 veneers that seem affected need to be replaced? Was this poor technique or can this happen to any dentist? Is it fixable? Thank you!

This is from leakage that occurred due to the gums bleeding during the bonding process.  I would schedule an appointment with your dentist to evaluate and give possible solutions.  It is likely that the ones affected will need to be replaced.  Good luck.

It is very important during the cementation for  your gums to be  healthy and have zero bleeding.  However, sometimes during removal of temporaries, gums bleed.  Also if you didn't have the proper hygiene during your temps, your gums can bleed and make cementation very hard.  At this point the only way to get rid of the blue and dark lines, is to change those veneers.  Good luck.

It is likely to actually be the condition of your gums around the time of cementation. That most of the veneers were without problems means that the overall technique was fine, but where there is a lot of bleeding, the is a lot of fluid pressure trying to displace the adhesive and take its place. Wherever there is missing adhesive which is replaced by blood you will get this effect. On the positive, if the level at which the adhesive is displaced is outside the bond surface, the damaged glue can be chipped (or more commonly grinded) off. Speak to your dentist, and maybe start with a hygiene appointment so your gum health is imp[roved before the treatment is done.Good luckThomas Dey, BDS, MSc

I am thinking Two possibilities:1) Failed/Contaminated bond with micro-leakage2) Discolored root/tooth (sometimes associated with a endodontically treated tooth or previous metal filling)You can re-seal the edges of a veneer if the color can be bleached/cleaned off but if it re-occurs, usually have to be replaced.  Contact your dentist and let them examine and suggest options soon.

Hi:If the bluish tint is under the veneer, most likely the veneer has to be replaced due to blood seeping under the veneer at the time of cementation.  I suggest you go back to your dentist to have him/her evaluate the discoloration.  Sometime the discoloration can be superficaial, in which case it can be polished off.Best,Dr. Maddahi
