hi..there are different ways to improve buttocks shape..but unfortunatly except exercise there is no other way to do this..
there are surgical and non-surgical alternatives to give fuller, more rounded buttocks:
Exercises like squats will build the gluteus muscle and tone the buttocks.
Surgical butt enhancement treatments include fat transfer, butt implants, and the Brazilian Butt Lift treatment.
Implants have the advantage of adding permanent volume to the buttocks, but has higher risks for infection, seromas and malpositioning.
The fat transfer procedures (including Brazilian Butt Lift) is less invasive than implant augmentation, and the required liposculpture helps contour the gluteal area. A disadvantage is that the amount of volume that remains after a year varies from person to person.hope you got your answer,,,thanks

HI,

I'm answering your question just going according to what you have said in your query. I haven't examined you so its difficult to be sure.

Im also assuming you are female. The side dents as you call them are called "trochanteric hollows" and are present in everyone more in males though. If you have smaller hips then they are more pronounced.

They become more prominent after maturity. Since you need to fill it up with fat, there is nothing much you can do non surgically. Just maintain a healthy diet.

Surgically you might require a fat transfer to the area to make it smooth and even and uniform once you are old enough i.e

Medically I do not think you should be too worried about it. It should not cause any issues to you from a medical standpoint.

All the best
