Any orthodontists around? Lost brace

[IslaValargeone]

Have just dropped bottom piece of twin block brace down a drain (Don't ask)
Practice is closed until Monday. Should dc continue with upper appliance still, or will that cause problems if lower brace isn't being worn?

If the top piece doesnt connect to the bottom piece when in the mouth and each brace doing their own job then it shouldnt matter if you wear the top one or not BUT if you notice dc grinding/doing something odd with their teeth etc then stop wearing the top one till Monday weekend break will not do them harm for long term health.
Hope this helps?X

Thanks Fizzy.
