Do you lazy or do not have time to brush his teeth? Better not because of the remnants of food on the teeth will eventually develop into bacteria that cause tooth decay.
However, if you really do not have time to brush your teeth, say the middle of a journey, do not worry, just chewing crunchy foods follows:
1. Apple
2. Raw carrots
3. Celery
4. Popcorn (unsweetened of course)
For best results, chew the food on top as a dessert can you feel did not have time to brush your teeth after eating.
