We found the dentist. Before he started I said "Accident 7 years ago, some teeth fell out". He looked and said "Root" 3 times meaning that was all that was left. He said you can either leave them or if you want us to remove them...... but I have loadsa work to be done on the rest anyway. Ahhhh.
He also suggested I but another electric toothbrush to make brushing more effective....
