This post is definitely not going to help everybody. Possibly, it will help nobody! It's just my personal story, from which people are welcome to draw advice/methods should they wish to.
First off, I do not naturally have AWFUL breath. What I've found is that I seem to develop a breath odour quicker than others do, and a stronger breath odour than others' at that. I had little idea why this might be, until around two weeks ago when I started seriously investigating my mouth and all therein, because it was really starting to get on my nerves, and had been progressively growing worse for years.
I think my problem with my breath really started when I was around 16 years old (I'm 24 now). My breath odour has never been chronically strong (I can't fill rooms or smell myself when I talk), but I was always aware when it smelt, due to a bad taste in my mouth and various other factors.
I know that when it smelt, which was probably 95% of the time, it smelt quite unpleasant.
I have really good teeth and gums. I've never had a filling or any sort of dental procedure, and my teeth are straight and a nice colour. I see a dentist every six months who has never noted any problem with me - and never noticed the smell of my breath, because after brushing, I could usually stay fresh for about an hour. So I fooled him every time.

People who think that having good teeth naturally entitles you to good breath are both a. ignorant and b. annoying. The same applies to those who believe anyone whose breath smells must not follow a good oral hygiene routine. I looked after my mouth really well and STILL I kept developing this idiotic smell, no matter how much I brushed, scraped, flossed, gargled and scrubbed. So I embarked upon a mission to get to the root of my problem, and here's what I have discovered:
- I have a fairly dry mouth, and definitely need to drink my 8 glasses of water a day (I was previously drinking around 3 a day or even less - bad I know).
- I have long tongue papillae. Some people are lucky enough to have smooth tongues, but I'm a Yeti by comparison.
- I have a partially erupted wisdom tooth - as others have said on here, this is ABSOLUTELY something worth investigating.
The first two problems were easy enough to remedy. Drinking lots of water is only going to do you good (as long as you're not drowning yourself with the stuff) and it really helps with dryness-induced odour. As for the tongue, I just make sure I'm extra vigilant when cleaning it - Orabrush, followed by a good scrub with a manual toothbrush and toothpaste, followed again by the Orabrush, and finished up with a spot of Tung Gel on a Tung Brush (rinsing in between these steps of course).
I found very quickly that if I did this morning and evening, and gave my tongue a quick scrub after meals, I could keep it really clean. Previously, although I used an Orabrush, it would develop a fairly noticeable coating at the back and in two strips along the sides. And it stank. Even more so if I ate, and the food debris got stuck to the existing coating for all those stupid bacteria to enjoy further.
But what I really wanted to know was WHY my tongue stank. Obviously, there was an overgrowth of bacteria in my mouth for some reason, which was allowing these microbes to feast so indulgently on my poor tongue and make me pong. Enter my wisdom tooth.
As I said before, my problems started when I was about 16 - the exact same time my wisdom teeth began to erupt. First it was the upper ones, which took a couple of years to come through ... I hate to think of all the rubbish they were trapping until they finally erupted entirely. Around 2008, my left lower wisdom tooth began to appear. This is when I started to notice that if I touched the gum covering it, my finger would smell awful. I got by with the use of interdental brushes, inserting one into the space and moving it around a bit (bringing it out smelling like death) - with hindsight, this probably didn't help my breath much at all, but at the time I didn't realise that the bacteria feeding on the food trap of my wisdom tooth were causing all the other problems in my mouth. Eventually, that tooth came through too and I was acceptable ... for a while ...
This last one, on the right side of my jaw, is the worst. It's been sitting in the same position now for at least two years, with a piece of gum covering it. There are a couple of reasons why I can be sure it was definitely this tooth that was causing my bad breath. Firstly, the coating and bad taste on my tongue was far worse on this side. I also recently managed to pull almost 30 tiny tonsil stones, around poppy seed size, out of a crypt behind my right tonsil. I got two out of the left one. And I know this wisdom tooth seeping its sewage into my mouth and down my throat all the time is to blame!
Wisdom teeth are horrible. Even if yours are fully erupted, if you suspect they may be trapping food and other gunge, consider having them removed. I should be getting all of mine out sometime this year, and I can't wait. Until then, I'm using my Panasonic EW-DJ40 oral irrigator to flush out the space every day, sometimes two, three, even four times a day. I've been doing all this now for around two weeks, and it's really working. The smell that comes from that tooth when irrigating, however, is inhuman, but getting it out at least means other people won't have to smell it. I am so looking forward to having all four of my wisdom teeth pulled so I can finally relax.
