Can drones fly with small dents in the blades?

Hello,

When i was installing my blades in my helicopter, i got some small dents because one blade fell to the ground.
There is no clear crack or fissure, just a small dent missing in the end of the blade.

Will that develop into something more serious or dangerous if i continue using them ?

I suggest you offer us a picture of the damage with a ruler alongside. I can't see how simply dropping a blade can cause much damage.

here it is. sry forgot the ruler, but you can see the extent of damage (2 blades have small damage, first 2 images have the biggest one). Can i still use this ? i plan to use them for activities under air authority regulation. Are they still air worthy ? because it is ridiculous to spend 250 euros because of this crap ...
thanks

As far as flight goes, I don't think this is something that will make much difference as far as it's airfoil/wing function. My only concern would be possible balancing issues and if the blade will worsen over time. Most composite polymer props structural integrity wouldn't be compromised. However if it's wood or fiberglass, I'd keep a close eye on it.

it is carbon fiber
 
As long as you aren't having any balance issues you should be fine with the small imperfection in the rotor. I've seen quads with badly niched rotor blades fly just fine.
