It is easier to chew a small piece of gum discreetly rather than a big piece of gum. If you can, choose a thin stick of gum over a block or cube.
Choose a non-colored gum; one that is preferably white or pink and looks similar to the features in your mouth.
If you lift up your upper lip to your nose you will see your gums. Hide your chewing gum there and suck back to flatten it. This can be painful if done for too long.
Try to think like a teacher. Consider what tactics a gum chewing student might use to avoid getting into trouble.
The longer you chew the same piece of gum, the harder it gets to chew. Note that this may lead to more noise when chewing. Chewing can also help the scent of the gum to dissipate more quickly.
When answering yes or no questions, feel free to nod instead of answering.
Place the gum under your tongue, behind your lip, or inside your cheek. This will help keep it hidden.
Remember, you don’t have to blow bubbles in order to enjoy gum.
If you have braces, and the teacher sees you move your mouth in a chewing motion you can always say that it was wax. If you think your teacher is suspicious of you having gum, ask to go to the bathroom to fix the wax/bracket/etc. It makes them think it was an orthodontic issue, not chewing gum! If the teacher smells your gum and asks about it, hide the gum in your mouth or simply say you had some candy earlier. If they ask what candy, answer with something that smells like your gum.
You can also pretend to blow your nose while discarding the gum. Remember, some teachers know this trick, so avoid doing it too often. After all, they were at school once too!
Avoid doing this with large globs of gum, as it may become a choking hazard.
When asked if you are chewing gum, reply, “Sorry, I’m very nervous” and state that you were chewing on your tongue. If they don’t believe you, open your mouth while hiding the gum and stick out your tongue. Keep in mind that your gum may fall out or fall down your throat while doing this. If you get caught, bite a little bit off and spit some of your gum in the bin. When walking back to your seat, you’ll still have a bit of the gum. Start chewing discreetly when your teacher’s back is turned.
