Any dental experts around? Embarrassing bad breath question.

[MatthewWrightResearch]

Can old fillings/root canal cause bad breath?

I've had a scale and polish last month and I still have bad breath, dentist says my teeth and gums are healthy. I have a feeling the cause of the smell is at the back of my mouth where I have fillings as the floss smells when used on that area and my gums bleed (only at one wee bit). At my next check-up what would be the next step? Would a x-ray help?

I use Oral B toothpaste/floss/brush tongue/C12 mouthwash. I don't have any toothache either.

Ime yes,the dentist told me fillings break down slightly and can cause a weird taste. Anyway I eventually needed it replacing after having them cleaned, x rays etc and there isn't an issue now.

Are you flossing?

Sorry, just reread your post

Nope, I've checked for stones and I've none.

The dentist used a waterpik when he cleaned my teeth, the cost has always put me off. I'll keep my eye on prices of the on Amazon.

Are you lactose intolerant? My DS is, and eating any yoghurt or milk with cereal leaves his mouth smelling like a sewer.
