Breath Smell

For the first time, my girlfriend tells me that my breath smells like cigarettes. I do not smoke, I have good hygiene and I see my dentist regularly. But I do drink about 3-4 cups of coffee per day. Is that why my breath smells like cigarette smoke, or could there be another reason? She also said that my breath does not smell of cigarette smoke, even when we are face to face, but only when we kiss Does the smell of cigarettes.

Your question contains the answer!
3_4 cups of coffee every day ... one likes or dislikes ... change your breath ..
Coffee has a particular pattern of worsening breathing and damage the enamel.
Therefore I suggest you rinse your mouth thoroughly after you drink coffee and have a bit of mint ... might help ..
