How do I get the right kind of dentures?

SEE THE RIGHT KIND. Of dental healthcare specialist. You get what you pay for...
Prosthodontist. Go to the specialist -- a prosthodontist. They are specially trained in this treatment. You will be glad you did. Good luck.
Patience . Properly-fitting dentures take on average 3-4 office visits for impressions, measurements, planning, etc. Avoid temptations of "dentures in a day" type advertisements. "immediate dentures" can be a great treatment option, if proper planning is done in the appointments leading up to the day of teeth extractions and denture delivery.
