Hi there I understand your concern....Oral malodor is primarily the result of microbial metabolism. The mouth is home to hundreds of bacterial species with various nutritional preferences. These organisms digest proteins, and several fetid substances arise, leading to bad breath...Oral malodor from the overgrowth of proteolytic, anaerobic gram-negative bacteria on the crevices of the tongue dorsum can be successfully diagnosed and treated.To reduce bad breath, help avoid cavities and lower your risk of gum disease, consistently practice good oral hygiene. Further treatment for bad breath can vary, depending on the cause. If your bad breath is thought to be caused by an underlying health condition,as we can't prescribe medication online as per law consult dentist or physician they will help you
First of all a dental check up would determine how good your oral hygiene status is,and how much plaque or tartar build up is present in your mouth.
Apart from that if you have any cavities where food is getting lodged and leading to the bad odour will also be diagnosed.Or any spaces or broken fillings which act as a food trap.
So once you have had a cleaning and all the above are taken care of it will rule out dental sources of Bad odour.
Other reasons could be of ENT origin or sometimes Gastric too. Thanks
Most common reasons for the bad breath is improper oral hygiene maintenance, leading to infection of gums and surrounding tissue ie. gingivitis and periodontitis..
The only way to treat that would be to remove the causative agents thus all the deposits (plaque and tartar) on the teeth needs to be removed, which is not always possible by brushing alone. Thorough professional prophylaxis needs to be done by an efficient dentist..
