I take your meaning to be "will another dental school open in Norman?" This is anot a decision for OSU, but for the state. It is highly unlikely that Oklahoma will open a second dental school in Norman. Almost all medical and dental schools centralize the basic science years on the home campus, but the clinical training may be decentralized.
It seems to me you are going to have to make the adjustment and sacrifice if a dental education is important to you, not the dental school nor the state. It is not uncommon for one marriage partner to remain at home and the other partner attend a professional school elsewhere, but the marriage has to be solid for that to work.
