Best breath (halitosis remedy) ?

[JungleRaisin]

I find I can perceive my breath to be not great once it’s the afternoon (dry mouth causes it which makes me feel on edge and unable to interact closely with others. I do the following already:

Brush teeth twice a day for 2 mins with electric toothbrush
Scrape and clean my tongue twice a day
Drink a lot of water during the day (but it all never hydrates my dry mouth)
I don’t take any medication that would cause dry mouth.
I think my breath is fine in the morning but gets very dry from 2pm onwards, everyday.

Any tips/products? Tried mouthwashes, brushing again etc but these dry out my mouth further and are only temporary fixes

Salivix pastilles may help or an artificial saliva spray? Both can be bought from pharmacies

How much are you drinking and what is it?

Thanks for the responses so far.
I’m drinking water - don’t like fruit juice etc. And around 1.8-2litres a day

Raspberry ketones. I took them because they were supposed to help you lose weight. They didn't but I had lovely raspberry smelling breath.

Floss floss floss

Thanks for the replies so far.

More replies appreciated - particularly for dry mouth which is more the issue I think that's causing it.

Do you floss or use inter dental brushes?
