The Conclusion

In the end there is no right answer because everybody has their preferences. I prefer mints while a majority of people prefer gum. If both contain sugar than they are bad for your teeth, but the sugar free variations are not harmful. Gum helps clean out the mouth by absorbing stuck particles and possibly whitens the teeth. But, it is considered rude to chew, loses taste quickly, and is difficult to get rid of. Mints, on the other hand, are more socially acceptable and do not require cleanup. So, given this information I urge you to pick whatever you think is best.
