This could cause injury to your teeth or throat.

In addition, when you chew an oyster, there is a higher risk of getting foodborne illnesses like norovirus or vibrio infection since chewing can allow more bacteria to enter your system.


In conclusion, there is no hard and fast rule when it comes to chewing or swallowing an oyster; it all depends on personal preference.
