Patient: Hello, Dr. Tan! After periodontal treatment, the doctor said that the teeth on my adjacent side were in bad condition, so a fixed denture was not recommended. So I had an invisible denture restored on October 15. This summer, I will have periodontal treatment and 3 invisible denture restorations for my lower front teeth. Dr. Tan, will the invisible denture cause gum recession on my missing teeth? If I want to have a fixed denture in the future, will I be unable to have a fixed denture if there is gum recession? TANJING: Hello: Some patients are prone to gum recession after using an invisible denture. Therefore I do not recommend the use of an invisible denture when the patient has periodontitis. If the gum recession is severe a fixed denture restoration may not be appropriate. If you have any questions, please continue to ask. Thank you.
