I have been told by my dentist that it can permanently damage your tooth enamel. I did a quick search and found an NIH study on enamel softening. It looks at hardness, but that is all. I only read the object and the abstract, but that part didn’t mention enamel thickness. The study mentions that hardness is restored after about a week.
I would generally advise caution and just take your dentists advice about these things. I will admit I am generally biased about this and it definitely can be harmful if not done correctly.
I recently had new rain gutters installed on my house, had my trees trimmed, had my patio paved, and bought a power bank. I’m fucking adulting damnit.
