If you have dentures and are in need of a repair, reline or a new set, it is a good idea to use a dentist with a lab on the premises. They don't send your denture anywhere and can fix it right on the spot. Also, you are there to try it in and confirm fit and look without having to send it back again. There are some denture labs that don't have a dentist on site. It isn't suggested to use these labs. There work isn't regulated, and is illegal.
