Why do people with bad teeth often get stomach problems?

The stomach and intestines are the organs that mainly digest food. They do this with the help of enzymes, so it is extremely important for them to get food carefully chopped so that every particle of food is covered with enzymes. For this, the digestive system begins with the oral cavity with the teeth with their tongue. If a person has bad teeth, some of them are missing, then he chews food very badly, swallowing large pieces. They are very poorly digested, remaining in the stomach for a long time. It damages our digestion.
