What do you recommend for gum disease relief?

See a periodontist. If you rely only on oral hygiene and not a definitive treatment, the periodontal infection and gum disease always will come back. Periodontist will treat gum disease by treating the cause and getting rid of the infection. A periodontist is a dentist specializing in the prevention, diagnosis and treatment of gum disease and alveolar bone resorption.
Good oral hygiene. Brush and floss and see your dentist regularly.
Good oral hygeine. Probably the best treatment for most gum disease is regular trips to the dentist for check-up, and good oral hygeine at home, like brushing regularly, and flossing. Poor oral health can lead to infections that can travel within the bloodstream.
Periodontist. Mild gum disease can be a simple fix from your general dentist. But, a lot of gum disease is under treated. It is a painless infection, so you are relying on someone's expertise to guide you. Seek a periodontist for an opinion.
