I get what you mean about the milk thing. My kid can’t have dairy either, and honestly, keeping a carton of milk around “just in case” feels kind of unrealistic, especially if you’re out or it’s expired. I looked into those tooth saver kits too after my dentist mentioned them—some have a little vial with a special solution that’s supposed to keep the tooth alive for an hour or two. But then I read mixed reviews... Some parents swear by them, others say they just panicked and ended up using whatever was handy anyway.
About putting the tooth back in—yeah, that freaks me out too. I know dentists say it’s best if you can manage it, but in the middle of all that chaos? I’d probably do more harm than good. Wrapping it up and heading straight to the dentist sounds safer to me.
As for water vs saline, I’ve heard that plain water can actually damage the root cells if the tooth sits in it too long. Saline is better if you have it (like contact lens solution), but honestly, who has that on hand every time? I’m thinking a little kit in the car with gauze and a mini bottle of saline might be worth it—at least then I’d feel less helpless if something happens.
