Hello thanks for consulting at hcm..
I understand your agony,, since constant hitting of tongue to retainers could be very painful,,
The solution for this problem can be--as follows:
The permanent retainers-wire could be covered with composites or if any rough edges are present,, request your
dentist to round off the rough edges..
Also try keeping the tongue in
palate position when you u close your mouth,,that way you could avoid tongue hitting on retainer wire..
Keep your
oral hygiene good.. brush twice daily,,
Hope it helps,,take care..
