Our body and throat along with oesophagus can only take in small particles and pieces of food which can help in easy ingestion .

Teeth help in tearing and grinding the food particles into small components or pieces which can easily pass through the oesophagus and reach the stomach for proper digestion .

Swallowing food to quickly or without chewing properly can cause indigestion which is again due to the large particles .
