Hi! There could be various reasons for bad smell or odor. Firstly, while brushing make sure you are cleaning your tongue with a tongue cleaner, which could be harbouring bacteria responsible for bad odor. It could be related to a gum infection (gingivitis), you can get professional cleaning also called scaling from a trained dentist or hygienist. Also many atimes due to food lodgement in a cavity or between your teeth can cause dental infection resulting in bad odor. I would suggest you to visit a dental clinic and check for any oral infections. Staying hydrated helps, you can use mouthwash or sugar-free gums to feel fresh.
If the odor doesn’t go, then get a thorough checkup done to evaluate any systemic issues causing bad breath- like diabetes.
