Dentists recommend brushing twice daily and flossing once. Each brushing session should last for 2 minutes so you can spend 30 seconds on the front and back of each of your top and bottom teeth surfaces. For fresher breath use mouthwash in between brushing.

Brushing once a day is better than not at all, but dentists recommend brushing twice a day for 2 minutes. Don’t forget to floss.

Signs of poor oral hygiene can include persistent bad breath and a buildup of plaque or tartar on the teeth. You might also notice red, swollen, or bleeding gums; tooth decay or cavities; and possible discoloration or discomfort when eating, all of which merit a visit to your dentist for further evaluation.

Mouthwash does not replace brushing or flossing. Instead, it serves as a supplementary step in your oral care routine by helping to freshen breath, reduce bacteria, and sometimes even fight plaque build-up. But mouthwash doesn't mechanically remove food particles and plaque from your teeth and gums like brushing and flossing do.

Brushing three times a day is generally not too much if done with proper technique and a soft-bristled toothbrush. However, it's important to use gentle strokes and avoid brushing too aggressively, as excessive force can lead to gum irritation or enamel wear over time. For most people, brushing twice daily—morning and before bed—is typically sufficient, but if you've been advised by your dentist or feel the need to brush after meals because of specific dietary habits, brushing three times is acceptable provided you maintain the right brushing technique.
