According to Dr. Matthew Messina, dentist and lecturer at Ohio State University (USA), Chewing sugar-free gum after meals can support oral hygiene, by stimulating the active saliva gland to work more strongly. Saliva helps neutralize acids in the mouth and wash away bacteria - the main factor causing tooth decay".
In addition to oral benefits, gum is also said to help improve concentration and alertness. A study published in the journal Appetite (UK) showed that people who chew gum at work tend to be more alert and reduce stress slightly. Chewing at regular rates can create a feeling of relaxation, helping the brain turn the channel from immediate anxiety.
However, chewing too much gum, especially sugary ones, can be counterproductive. sugary candy contributes to increased the risk of tooth decay and digestive disorders. Meanwhile, sugar-free foods often use artificial sweeteners such as sorbitol or xylitol - if used too much, it can cause bloating and diarrhea.
In addition, chewing too often also leads to the risk of jawline disorders. Consistent chewing can strain the jaw muscles, leading to headaches, neck pain, and joint problems. I have met many patients coming to the clinic just because they are addicted to rubber candy, Dr. Messina shared.
Experts recommend chewing unsweetened gum for 10-15 minutes at a time or 1-2 times a day as a safe bet. Prioritize choosing foods containing xylitol - a substance that has been shown to fight bacteria that cause tooth decay.
Chewing gum is not necessarily harmful, but like any other habit, you need to be moderate and understand the purpose. Using candy as a health support tool, not a replacement for toothbrushing or oral care.
