Many things can cause bad breath. The most common cause is food residue and plaque left in the mouth after a meal. Chewing gum can be a quick way to reduce mouth odor after eating, but the effect will not last long.
To ensure that there is no halitosis after a meal, it is important to brush the floss to remove any plaque that may be present between the teeth and between the teeth and the plaque on the teeth. Brushing your tongue is also important because a lot of food debris will accumulate there and produce a terrible odor in your mouth.
If you follow all these hygiene measures and still have bad breath, you can ask the dentist to talk about it. You may have gum disease or dry mouth and often cause bad breath. In addition, if there is tartar around your teeth, only tooth cleaning can eliminate it.
