When food gets stuck, it can dissolve to different kinds of sugar. Then the bacteria in your mouth eat those sugars and produce acid. This acid is what ruins the teeth. And because of this, you have different kinds of cavities. Proper hygiene also entails brushing your teeth twice a day, morning and evening, after you’ve eaten. There is no set length of time to brush your teeth for – it’s quality of the tooth brushing that matters rather than the amount of time taken. An electric toothbrush is a recommendation that most dentists promote since it allows for through tooth cleaning, especially in hard-to-reach places. Flossing at least once a day to remove all the residues or the food and plaque that you have in between the teeth is highly recommended.
