I'm 52 and want to widen my smile w/ veneers b/c of narrow arches and deficient Buccal C.Should I first get the DNA Appliance?

remember , veneers are for aesthetic improvement and not for widen arch. best option for you is arch expansion by DNA appliance or  damon braces or  invisalign. as u have narrow arch + large buccal corridors . after arch expansion , u can go for porcelain veneers for aesthetic improvement.

I strongly suggest you do the DNA Appliance first followed by ceramic veneers as the best approach.SARP can give rapid expansion but is not as good as the DNA 3 dimensional Expansion.It is possible to do 10 teeth of composite veneers to creeate a full wide smile and then do the DNA Appliance to correct underlying problem.  It will be more expensive in the long run but give you the finest treatment of orthopedic correction and cosmetics during treatment.  Ceramic veneers can be place after expansion is complete.Ideally 8-10 veneers.Ira L Shapira DDS, D,ABDSM, D,AAPM, FICCMOPast Chair, Alliance of TMD OrganizationsDiplomat,  Academy of Integrative Pain ManagementDiplomate, American Board of Dental Sleep MedicineDiplomate, American Board Sleep and BreathingRegent, Master & Fellow, International College of CranioMandibular OrthopedicsBoard Eligible, American Academy of CranioFacial PainDental Section Editor, Sleep & Health JournalMember CRANIO Editorial Board, Journal of Craniomandibular and Sleep PracticeMember, American Equilibration SocietyMember, Academy of Applied Myofunctional SciencesMember, Academy of Cosmetic DentistryLife Member, American Dental Association

Hello,
I think that the 20 veneers, 10 above and 10 inferiors can be made, however the overbite is worrisome because this can generate a risk in the durability of the veneers since they can fracture due to the pressure that will be applied to the teeth.I believe that it is the first thing that you should perform and in the best possible way an orthodontic treatment.If you want to make veneers in porcelain you must take into account these risks.
