My teeth keep chipping and I I don't know what to do! (photo)

Okay so, around summer this year the bottom of my canine tooth and the tooth under it chipped and the dentist said it would be fine so I didn't bother about it but since the the the side of my front tooth chipped when I accidentally hit my tooth brush against it, the it also a small chip on the bottom, they is not a larger gap at the bottom of my two front teeth and it is just upsetting me so much because I had really good, healthy teeth and now they are chipping away, I am only 16.
