People chew gum for a variety of reasons, spanning oral health benefits, stress relief, and even habit.
Oral Health Benefits
One primary reason is its positive impact on oral health. The act of chewing gum, especially sugar-free gum, increases saliva production. As noted by the American Dental Association and Mulgrave Dental Group, increased saliva flow helps wash away food particles and harmful sugars, reducing the risk of cavities. The increased salivary flow and volume is a direct result of mechanical action and the stimulation of oral taste receptors. Therefore, chewing sugar-free gum, as part of a regular oral hygiene routine, can contribute to better dental health.
Stress Relief and Improved Concentration
Research, as cited in studies like "Effect of Regular Gum Chewing on Levels of Anxiety, Mood, and...", suggests that chewing gum can be a simple and effective method for stress reduction and improved concentration. The rhythmic act of chewing may have a calming effect, helping to alleviate anxiety and improve focus.
Other Reasons
Beyond oral health and stress relief, people chew gum for other reasons:
- Habit: For many, chewing gum is a simple habit, often linked to boredom, nervous energy, or simply a sensory experience.
- Fresh Breath: Chewing gum can temporarily mask bad breath by stimulating saliva production and cleansing the mouth.
- Altitude Changes: As noted on Quora, chewing gum can help to equalize pressure in the ears during altitude changes, alleviating discomfort.
- Nicotine Replacement: Nicotine gum is a medically approved aid for quitting smoking, providing a controlled nicotine dose while satisfying the oral fixation associated with smoking.
It's crucial to note that while chewing gum offers certain benefits, it is not a replacement for proper brushing and flossing. Furthermore, sugar-containing gum can contribute to tooth decay.
