I have a gap between my 2 front teeth it's 1.5-2.0mm. Is it to big to get bonded? (photos)

Looking at your pic (although not completely clear) , most probably you can close it with bonding. to be more sure , an evaluation and a measurement needs to be done for the front teeth. If bonding didn't close the gap completely, a combination of bonding and  braces (just the two front teeth) will do the trick.

Yes, bonding is a great way to correct this space.  It is fast, easy, and much less expensive than porcelain veneers.  You just need to find a dentist that is experienced and can show you before and after photos of patients that they have done this procedure on.  The procedure, when done properly, should last from 3-7 years or longer.  With regular visits to the dentist, proper maintenance, and occasional touchups if a chip should occur, they can be made to last for 20 years or longer.  Go for it!!!!!!!!!!!!!Dr. Gary Braunstein

Absolutely you can close that gap with bonding, either completely or almost completely.You could also pull those teeth together with a simple elastic approach and do bonding between laterals and centrals where discoloration of bonding over time is less of an issue.If you were a patient in my practice I probably would be discussing widening your maxillar with a DNA Appliance.  I prefer a fuller wider smile and better airway.  That said, you are adorable and I love your dimpls.Do you always have the  dark circles under your eyes?  This may be due to your arch form.Ira L Shapira DDSDiplomate, American Academy of Pain ManagementDiplomate, American Board of Dental Sleep MedicineFellow & Regent, International College of CranioMandibular OrthopedicsChair, Alliance of TMD OrganizationsThinkBetterLife.com
