Here are some other options, depending on the context:
* मसूड़ी की गम (masoodi ki gum): This literally translates to "gum for the gums", emphasizing its use for chewing.
* चबाने वाली गम (chabane wali gum): This literally translates to "chewing gum" and is a more formal way to say it.
* गम (gum): This is the most basic and straightforward term, but it can be ambiguous as it can also refer to other types of gums.
The best choice depends on the specific situation and the desired level of formality.
