Hi. Thanks for the query. Bad breath also known as Halitosis can occur due to a number of causes like poor oral hygiene, oral and dental infections, post nasal Chat Doctor. . If you brush too much and for long duration then teeth can become sensitive, so it is advisable to brush your teeth twice a day only and that too not more that 2-3 minutes. You should consult an Oral Physician or an Otolaryngologies 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. As of now you should start gargling with a flavored mouthwash twice a day. You should chew flavored sugar free chewing gum. Do warm saline gargles twice a day. Limit the intake of high aroma foods like onion and garlic.
