I have suffered from gum disease for years. What treatment would you recommend, as my dentists says I should keep my teeth?

Q. Hi, I have for about 10 years had a gum disease problem, I am told it\’s heredity. My gums are very sore and with regular cleaning by my dentist I find my teeth are getting more sensitive to cold and generally are quite sore to brush and floss. I hate the look of them and feel I should get a fixed restoration to put a final stop to the problems I am having. What would you recomend I do? where should I go to get the treatment I need?. My dentist tells me to hold on to the teeth, but I feel am fighting a loosing battle.,
