I am a 50 yo female with both partial upper and lower plates. I do not wear the uppers because they don't fit right. Over the past several years I have developed a huge overbite with a large space between my two front teeth. I also have been diagnosed with gingivitis. My question is, can the overbite and space be corrected if wearing dentures? If so, will I need to have a new plate made since the overbite developed before I was fitted? What type of dentist should I be looking for? I do not have access to my old dentist since I have moved out of state.
