Dentures are generally worn during the day and taken out at night to give the oral tissues time to relax. During the first few days after receiving the denture, however, it needs to remain in the mouth even when sleeping to best identify areas that need to be adjusted. This is especially important after receiving an immediate denture, for the gum tissues will swell after the teeth are extracted or lost and then may not permit the denture to be reinserted if taken out.
It was our impression from viewing the video that this technique is very dependent on the dentist's skill in performing the needed steps (more so than with conventional construction, primarily due to time constraints needed to accomplish certain steps, and accomplish them the first time, properly, before the denture materials set). So in that regard, likely the dentist who fabricated your mother's denture is due as much credit as the system itself.
Later that afternoon I came back to have 16 teeth extracted. I got to the office and waited about 30 minutes before I was seen. I got to the back and began injections. After this I went to a full blown panic attack and came close to passing out. The one positive is the dentist who was working on me took it in stride. I wasn't treated disrespectfully and after about 30 minutes the panic subsided and she was able to finish my injections and begin pulling teeth.
Removable complete denture. This denture sits on top of the gums where the missing teeth were. It can be uncomfortable, affect your ability to experience the full taste of food, cause sore gums, and shift and click in your mouth when you speak, eat, smile, yawn or cough. While the initial costs are low, they only last an average of 7 to 15 years, and the replacement costs can be significant over the long term. They need to be removed regularly for cleaning, which can be a time-consuming hassle. Also, as with a partial denture, the natural bone underneath a complete denture may deteriorate over time, permanently changing the appearance of your smile and face.
