Teeth

So my naturally perfect straight teeth have been ruined!!! Long story short I fainted and knocked myself out which caused me to bite completely though my lip and  has cracked like more than half of my front tooth off
Are caps/ crowns realistic??? Do they look like natural teeth?? I look so weird. At the hospital they said the dentist may say that I need the front two removed as they're so wobbly but could be bruising in my gums. :( 
Are implantation teeth good? Do they stay in?? I'm worried pls comfort me someone. I realise how sad I sound but like if u saw my face you'd understand
