Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain
bad breath also known as
Halitosis can occur due to a number of causes like poor
oral hygiene, oral and dental infections, tonsil stones or tonsilloliths,
post nasal drip, sinusitis,
acid reflux,respiratory infections, diabetes etc..
Smoking is a common culprit and smokers tend to have a bad smell and if you have not smoked at that recent moment it is not necessary that you will not breath bad as your lungs are continuously rottening and accumulation bad smell..
You should consult an Oral Physician or an Otolaryngologist and get evaluated and a thorough clinical evaluation and investigations depending upon suspected cause can help in diagnosis..
Treatment of underlying cause will relieve the symptoms..
First and foremost thing that you need to do is to "STOP SMOKING"
As of now you should start gargling with a flavoured mouthwash twice a day..
You should chew flavored sugarfree chewing gum..
Do warm saline gargles twice a day..
Limit the intake of high aroma foods like onion and garlic..
Drink plenty of water and maintain a good oral hygiene..
Hope this information helps..
Thanks and regards.
