Best Practices for Oral Hygiene

Maintaining proper oral hygiene is essential for overall health and well-being. By following these best practices, you can ensure that your mouth stays healthy and free from potential issues.

Regular Brushing and Flossing

Brushing Twice a Day Brush your teeth with a soft-bristle toothbrush at least twice a day, preferably in the morning and before bedtime. 

This helps remove food particles and plaque buildup that can lead to cavities and gum disease.

Using Fluoride Toothpaste Choose a toothpaste with fluoride, as it strengthens tooth enamel and helps prevent decay. Use a pea-sized amount of toothpaste on your brush.

Proper Brushing Technique Hold your toothbrush at a slight angle and use gentle circular motions. Brush the front, back, and chewing surfaces of your teeth, as well as your tongue.

Flossing Daily Flossing removes plaque and food particles from between your teeth and along the gumline. Floss at least once a day using a gentle back-and-forth motion.
