When dentures no longer fit well, the correct action is to seek follow-up care. Denture adhesive is recommended for dentures, even well fitting ones. Adhesives improve retention, seal the borders to prevent food from slipping under, and cusion the soft tissues from the rigid acrylic. Using denture adhesive may improve the fit, but it tends to work best when only a small amount is used. Covering the entire denture fitting surface in adhesive makes it stay in less well. Adhesives may compensate for gradual loosening of a denture, but it is only a temporary solution; it does not solve the problem. Fortunately, dentures can often be relined with relining materials to improve the fit, and this process costs less than creation of new dentures. Overall, a well-made denture could last about 5 years (or more), but this is different for every patient.

Dentures are just one option for replacing missing teeth; some of the others include fixed bridgework and dental implants. Each method has its particular pluses and minuses, which should be carefully considered. There are also several varieties of dentures available to address specific issues, from partial dentures to implant-supported overdentures. The best option for you will depend on your individual situation.

My teeth are never secure and have to reapply adhesive several times a day. Is this normal?? Think I'll find somewhere else for my lowers... get what you pay for. I was having severe pain in some of my lower teeth on that last visit, also. I asked for a Rx for antibiotics but Renee told me I did not need them. I now have an abscess and look like a squirrel. Thanks, Renee!! By the way, Renee, the mouth does NOT exaggerate!! Thanks for your great patient care!!!
No consensus has been reached regarding the best occlusal scheme for making complete dentures. Thus, the purpose of this systematic review was to compare bilateral balanced occlusion (BBO) with other occlusal schemes (canine guidance, lingualised occlusion and zero degree) in complete dentures. The schemes were compared in terms of quality of life/satisfaction and masticatory performance. Two independent reviewers performed a comprehensive search of studies published in or before October 2017 using the PubMed/MEDLINE, Scopus and Cochrane Library databases. The search was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The focused question was: "In conventional complete denture, is BBO better than lingualised occlusion, canine guidance and zero degree in terms of quality of life, patient satisfaction and masticatory performance/muscle activity?" Seventeen studies were selected for analysis. In total, there were 492 patients with a mean age of 64.78 years and a mean follow-up duration of 2.96 months (range: 1-6 months). All studies compared BBO with the other occlusal schemes. Eleven studies evaluated the influence of the occlusal scheme designs on quality of life and satisfaction, and 8 studies evaluated masticatory performance and muscle activity between BBO and the other occlusion schemes. The present systematic review indicated that BBO does not confer better quality of life/satisfaction or masticatory performance and muscle activity. Thus, lingualised occlusion can be considered a predictable occlusal scheme for complete dentures in terms of quality of life/satisfaction and masticatory performance, while canine guidance can be used to reduce muscular activity.
^{Tooth extraction and restoration: If tooth decay or gum disease is so severe that a tooth can't be saved, it will need to be extracted. Your dentist will examine the remaining teeth in your mouth and determine if they should be removed or restored with tooth-colored fillings, inlays, onlays, or dental crowns. After the teeth have been extracted, the gums need at least two to three months to heal before an implant can be placed or an impression taken.}

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.
