Please choose the correct ending to complete the given sentence: Health: [header] How to get good breath [title] Brush and floss every day. [step] You should try to stick to a regular brushing schedule so your mouth stays clean and free of bad-breath-causing bacteria. Brush your teeth twice a day, once in the morning and once at night.

Ending1: [substeps] Bacteria build up in your mouth and needs to be loosened up so that you can breath properly. Try to brush your teeth each day and floss only one time a day to prevent bacteria from building up. Ending2: This will make flossing fresh, sensitive and rough. It will also help to remove the plaque and bad-breath odor from your teeth. Ending3: Brush your tongue after brushing to avoid the risk of them sticking to your tongue. [substeps] Be careful with the usage of breath-stopping mouthwashes! The fungus that's causing bad breath is located in the throat opening. Ending4: Brush after meals (though you should wait 30 minutes to brush if you consumed something acidic, as this softens tooth enamel). Use toothpaste that contains baking soda and brush in small circles in the front and back area of your teeth for two to three minutes.
