Are my horse teeth dentures fixable??

Once the denture is made you would likely need to have a new one to change the size of the teeth.  See what your dentist has to say in the morning.  Good luck.  

Your case reminds me of a patient who arrived to my office boasting how great his previous doctor was, but his new dentures looked like horse teeth.  He said the doctor tried adjusting them twice & was told he needed to adjust to the new dentures.  Now, he wanted me to adjust them.To reduce the length of the "horse" teeth, I would have to cut the teeth down close to the gum.  Also, grinding down the denture from the inside is not an option.  Pksummerfield, you need a new denture.

Sorry that happenedUnfortunately if the dentures have been processed they will need to be remade.When they are remade request a cosmetic try in so these types of problems do not occur againBest RegardsDr J
