why dont more dentists offer Laser bondings?

Outside of dr Sam Lavi my dentist's office I just had 6 lower theeth bonded at once by his Waterlase.
Quick and pain free and no drill, no needles, thats why I like it!
What do you think?
I asked for a lighter shade of tooth bonding color.
Thinking ahead in case of coffee and tea stain. Smart me!
