Yes, you can smell your own breath, but it's often hard to detect because your brain filters familiar smells (nose blindness), so you need specific tests like licking your wrist or smelling floss after using it to get an accurate idea. If you have a bad taste in your mouth or notice a white film on your tongue, you likely have bad breath, and asking a trusted friend or dentist is the most reliable way to confirm.
Bad breath odors vary, depending on the cause. Some people worry too much about their breath even though they have little or no mouth odor. Others have bad breath and don't know it. Because it's hard to know how your breath smells, ask a close friend or relative to confirm if you have bad breath.
