Small chip in front tooth. Is it worth getting bonded or leave it alone? (Photo)

I’ve had a very small chip in my tooth for a while, all my friends and family say they don’t notice it at all but it’s something I notice a lot because I had braces forever and my smile is very important to me. I felt like over time it has gotten bigger but once I look back at photos from when it first started it hasn’t changed much. Should I get it bonded or leave it alone? How much would it approx. cost to bond a chip this small?Photos attached are zoomed in up close
