I have a small crack in my tooth I am planning to go to dentist. I am wondering what they might do as treatment.

I noticed when I put my phones light over my front upper canine there is a dark line and a small abrasion this would be a crack right? You cannot see it without direct light so I wanted to get an idea of what type of operation might be done. Its a small little crack in the front middle piece of the tooth. I'm guessing at the moment a filling would be done. I'm not worried about the aesthetic I just dont want it to erode. Any suggestions. Cause craze lines dont reflect light right.
