I got two crowns for my front teeth a few years ago. Over the past few months, I noticed a small hole developing between my two front teeth. The other day, while I was flossing, a very small part of one of the teeth chipped off. Now, it's making me paranoid. It looks awful when I smile or even just talk. What's causing the hole? How can this be fixed? I do not want to lose these teeth especially that they are my front teeth.
Thank you for your help!
