I went to my dentist today as I'm having new dentures after 15 years.
She took a top and bottom impression and then said to make a further appointment for the next impression.
Due to reading about Paddy's problem I asked her what the second impression was for. She said that these days, they take an impression with a general mouth piece which is large enough to fit anyone and then send the 1st impression to the dental mechanic who then makes a special mouth piece to fit my mouth and gums for the second impression.
Apparently, they get a better fitting denture this way by having a special mouth piece to suit my mouth.
The dentist ( a young female) was very good today so fingers crossed for next week.
I'd certainly kick Paddy's dentist into touch if he can't do it properly by now.
