Teeth grinding

I’m not sure weather this is something to worry about or just over teething so thought I’ll try and get peoples opinion. In the last 3-4 days Luna keeps making this grinding noise with her back teeth, it sounds kind of the same as when she’s chewing a bone. She’ll only do it once or twice then stop for few hours then do it again. She won’t really let me look that far back her mouth without starting to panic so I can’t really see if anything is going on there but her gums look healthy, she’s not in pain either coz she’s still chewing everything as usual. Is it just over teething or should I take her to the vet? She’s 7months old so could be a loose tooth in the back or something?

She should have finished teething by now, although it's not unheard if for a pup to lose its last teeth at 7 or 8 months.

If you're concerned that it isn't normal & you can't look yourself, I would see if a vet or vet nurse could have a look & see if all the molars have come out - it could be that one has stuck there & is rubbing on the new teeth. If that's the case your vet might want to pull it out.
