Veneers Appear to Protrude Outwards and Look Bulky?

If you got the "no prep" veneers (Lumineers is most common) then they WILL be bulkier.  Normally, impressions are taken before treatment and a wax "blue print" is made.  From this you can tell if the veneers will appear bulkier.

 

6 veneers is the magic number.  The number to avoid.  Doing six is a compromise and often leads to aesthetic disappointment, as a full smile is 8 to 10 teeth.  6 is incomplete.

 

With what you have, you MIGHT be able to reshape them and thin them out.  If too aggressive, you will have very smooth teeth, not the normal wavy surface, so you may need to consider a new set of veneers.

Bulky veneers are usuallty caused by inadequate reduction of the tooth surface. Also you could have chosen a non prep veneer like lumineers which look bulky no matter what. You mentioned you had 6 done and your teeth are small. Your smile is not asethically pleasing from the side.  If you do not want more veneers, you are not going to be happy, because it sounds to me like you see large veneers in contrast to your original teeth which are small. Am not sure the veneers can be reduced further to have them balance your other teeth. If too much is taken from the veneers they lose the color and light. Your other option would be to try a mock up of veneers on the bottom to see if more of a balance is created. You might like what you see!

Bulky and protruding veneers could be due to a poor preparation and inadequate tooth reduction. While your original teeth may have had some protrusive angulation, generally, inadequate reduction of tooth structure and poor shaping of the underlying tooth can result in overcontouring. This is reflected in the appearance of bulkiness and/or protruding veneers.
