Chipped tooth! Help!

Hey y’all my little guy (almost 20 months old) has repeatedly chipped his front tooth.

Once when he was learning how to pill himself up and again after that, on the same spot twice. Ugh! It’s unfortunately turning black and the enamel is worn off.

What do you do for something like that? I’m guessing get it capped at the dentist but I’m sure he’s too young for that. Anyone been through this experience or have any advice? TIA!
