My front tooth was knocked out when I was a youngster. Last year, my cap (or whatever it's called) fell out and I went to the dentist. She diagnosed gum disease and said she would not put in a partial unless I received extensive cleaning treatments first. I need my partial as I work with the public. She has refused to give me a partial stating she would be liable if she didn't treat my gum disease first. Can she refuse to give me my partial? I think she feels I won't be back for the treatments. Can she do this?
