The DNA Appliance and Epigenetic Orthodontics is and excellent method to correct your issue. You have a narrow maxilla and narrow upper arch. You may also have a slight shift of your mandible to your right side (hard to be sure from photo without eyes).Ideally your dentist would have expanded your mouth prior to eight years of age. As an adult the DNA Appliance gradually grows the maxilla and is only worn 12-14 hours/day. As the maxilla grows it supports your lips and gives you a full wide smile hat is physiologically healthy. The lower jaw can reposition properly when there is sufficient room for proper positioning. This will improve your relaxed lip posture, profile and even out your smile.Do You have and headaches or TMJ problems?As to being embarrassed to laugh or smile, you have nothing to be embarrassed about . You have a nice pleasant smile and will look far better just smiling naturally and not covering your mouth. You are far more aware of this issue than anyone else and it is easy to develop habits that are hard to break. It is possible to do veneers or bonding on the upper right bicuspid, lateral and canine to improve the smile overnight but expansion is the best long term solution. I have had patients that we do bonding on and then gradually remove it as expansion occurs to give immediate resultsIra L Shapira DDS, D,ABDSM, D,AAPM, FICCMOChair, Alliance of TMD OrganizationsDiplomat, American Academy of Pain ManagementDiplomat, American Board of Dental Sleep MedicineRegent & Fellow, International College of CranioMandibular OrthopedicsBoard Eligible, American Academy of CranioFacial PainDental Section Editor, Sleep & Health JournalMember, American Equilibration SocietyMember, Academy of Applied Myofunctional SciencesThinkBetterLife.comDelanyDentalCare.comIHateCPAP.comiHateHeadaches.org
