Most cases of bad breath after tooth extraction are caused by food particles trapped in the gums. If not cleaned regularly, this can easily lead to bad breath. If pain occurs, appropriate treatment with pain-relieving medication is necessary to effectively improve symptoms. Brush your teeth morning and night to maintain good oral hygiene, which helps alleviate bad breath. Drinking plenty of water and consuming more light-colored fruits and vegetables can also be very effective in reducing bad breath. When necessary, brushing your teeth further contributes to maintaining oral cleanliness.
