This chamber is called the oral cavity. Actually the entire space that the tongue and teeth are in is the oral cavity.
It's because the oral cavity all the way to the anus is "open" to the external environment. Internal body cavities are those that are completely walled off from the external environment by well defined structures such as skin, mysentary, etc. In contrast the GI tract is specifically designed to periodically open to the external environment an allow food to enter and waste to leave.
