I agree, it does look like your teeth are too small for your face. The laterals are mainly causing this problem.  The health of your teeth and bite are first priority. In general, before you do any restorative treatment (veneers or bonding) you should get an orthodontic consult and treatment if needed.  After orthodontic treatment, I suspect your laterals will still look set in and short, and you may be a good cantidate for a type of veneer that requires no drilling.My best to you!

I would definitely recommend Orthodontics to close the gap. Any type of veneer you get should be minimally invasive and should not involve cutting on your tooth. You are too young for that. You don't want to sacrifice your tooth structure for cosmetic gain when there are alternativesOptions1. Preparation less veneers for the teeth either side of the center teeth. These are veneers that are bonded directly to the teeth without preparation. Orthodontics is required first to position the teeth appropriately . A very very good technician is required to make the veneers2. Bonding - this is tooth colored material that is bonded to the tooth. This is also very conservatioveBest of luck on your journey
