Always remove your dentures before sleeping to avoid damaging them, dislodging them, and to give your gums some time to relax. Submerge your dentures fully in warm, but not hot, water to keep them from drying out and becoming misshapen. Only use denture soaking solution if your dentures do not have metal components as the solution can tarnish the metal.
The office people and assistants must be low wage workers. They have the typical low paid, high stress lack of concern for the patient. The person who did my form did not do it well. That was evidenced in the quality of the temporary denture. The Dentist who did the extractions was the absolute best dentist I have ever seen in my 55+ years. They give you a pill to take an hour before you get there and if needed, one when you arrive. It relaxes you and one was enough for me. I was ready to go to sleep. They took me straight in and the dentist took 20 minutes numbing every tooth with a local anesthetic. <<<<
