Temporary veneers throwing off my bite. Is it normal to have to go back a few times before they feel right? (Photo)

Often times, veneer temporaries can take several visits to
obtain the correct bite. The veneer temporaries are made of an
“epoxy-like” acrylic material that can expand and shrink when they absorb
moisture or encounter hot or cold liquids or foods. Also, usually the
dentist with “numb” the area of your mouth that you now have the temporary
veneers and when you were still in the dental chair, your actual, correct bite
may have become altered due to the numbness. Typically the temporary veneers
fit very similarly as the definitive porcelain veneers but you may notice some
small spacing between the actual tooth and the temporary veneer, especially if
cement was not used. My advice is call your dentist and make an appointment to
go in and see him to evaluate and make sure there is not a problem. If
the bite is off now, you develop some sensitivity or discomfort from hitting
too hard on one or more of the temporaries?

Temporary veneers are just that...temporary.  They are usually not glued so that cement does not interfere with the final fitting of the actual porcelain ones.  However it is not unusual, especially if you were numb at the preparation visit to need a slight  adjustment to your bite.  Your dentist may also need to polish the adjusted area so it does not feel rough, and perhaps recontour the area around your gums.  But remember these are only temporary until the real ones are ready.

Yes, have your dentist adjust them.  Many times in our practice we correct the bite utilizing the porcelain veneers.  We call it a mouth approach to your smile.  If you bite needs improving, it can make for a prettier smile in the outcome.  Good luck.  Dr. David Frey
