I had a dental implant and crown placed. It's shorter than my other teeth. Can it be changed? Unhappy with my appearance (Photo)

I had an impacted canine tooth, oral surgery to attach a chain to it + orthodontia. After tugging for a year, decided to have the tooth removed and get an implant. I just had the crown placed and I'm not happy with how short the tooth is- it looks odd The dentist thinks I may have to compromise because the space left behind after removing the retained baby tooth was large. He thinks lengthening the implant crown would affect how I bite down. I've been through so much and just want it right
