Your gums can tell when you’ve been “too busy” to floss. Flossing removes plaque from places your toothbrush can’t reach, helping reduce the risk of cavities and gum disease. Just one minute of flossing daily can help remove plaque in hard-to-reach spots and support long-term oral health. Consistency in flossing makes a difference. Call us +1 717-243-8888 to schedule a checkup and keep your smile healthy.
