How do I care for my dentures? When you receive your new denture your prosthodontist will make sure that it fits properly. However, your treatment is not quite finished as there is always a period of adjustment to become accustomed to your new denture. Your prosthodontist is committed to making you comfortable and is happy to adjust the fit of your dentures. Over time, the gums and bone supporting the denture will shrink causing the denture to become loose. Periodic visits to your prosthodontist are necessary to check the fit of your denture. It may be necessary to adjust and refit your denture. It is also important to check the overall oral health of your mouth to help ensure optimal results from your treatment.
