Oh, that's even worse. I can't imagine you would get such an uncomfortable result with all that money and time spent.
Dentures are tough I think some patients (that I have had) think they will be easier than bad teeth
but they are not. It is truly a learning curve to wear them with success.
Dentures have to me made with dimension that keeps your mouth open to a certain amount so that your jaw can work optimally and your tissues can be supported. Next, your bite has to be supported in a balanced way so that when you bite you do not tip them out in the front
, back or with side to side motions. Things like overbite are counter to the balance that a denture needs to have so it might not be possible to replicate that which you had before and had got used to over your lifetime. Consequently, this new way of biting must be adapted to in most cases.
I am afraid that the only thing I can advise is to see your dentist or get a second clinical opinion.
Alternatively, there are new soft and more pliable materials to make at least the upper one with which may make you feel a little more comfortable. They are usually thinner and more flexible.
I hope this helps.
