Hello mam Welcom to practo    You need to go for a dental scaling and after that get a flavored tooth paste. Brush your teeth after having meals regularly. Hope it will help you Regards Dr Muzaffar

Getting a dental check up will help to rule out if your bad breath originates from mouth . Cleaning and polishing will reduce mouth odor. Early morning tongue cleaning and brushing at night can reduce this condition . If mouth odor doesn't come down even after eliminating dental causes then you have to check your digestive system for GERD etc .
