1The Cotton Test
Wipe the top surface of your tongue with a piece of cotton gauze and smell it. This is probably the most honest way. Also, if you notice a yellowish stain on the cotton, it’s likely that you have an elevated sulphide production level.
2The Lick Test
Lick the back of your hand. Let that dry for about 10 seconds and then smell it. If you notice an odor, you may have a breath disorder because the sulphur salts from your tongue have been transferred to your hand after the liquid has evaporated.
3The Dental Floss Test
Run a piece of dental floss between your back teeth (this is the mostly likely place where you may get food caught) and then smell the floss. This may be an indication of the level of odours others detect.
4The Mirror Test
Stand in front of the mirror and stick your tongue out as far as possible. If you notice that the very back of your tongue is whiteish, it may be a sign that you have bad breath.
The Observation Test: Judge the reaction of others when you interact with them. If people are visibly stepping away then it may be time to do something about it.
5The Ask Test
Ask the opinion of someone you can trust (a good friend, a spouse, even your kids). Ask them to check your breath several times daily because breath changes throughout the day.
