Can this clinic help me with my bad breath or is it fake?

I have had bad breath for close to 2 years now, and have tried various remedies.
I have become fed up of trying self treatment, so now considering a clinic called "The Breath Institute" (based in Spain/UK)
Its run by a person named 'Doctor Jonas Nunes'

My concern is I don't know if this will help me and its also expensive, so would be a big burden if it doesn't work.

Can anyone tell me if this is a genuine option for treatment and if this clinic is legit, or if I should avoid it?
