Specialist doctors explain the effect of chewing gum on dental health and cognitive functions and define the rules for its use.
Dentist Natalia Akhrimushkina noted that sugar-free gum is only beneficial as a supplement to basic dental hygiene, as it increases saliva production, which helps neutralize acids and remove food debris. She advised chewing it for only 10 to 15 minutes after meals, warning that prolonged chewing can strain the jaw muscles and joints.
She emphasized that chewing gum cannot replace brushing and flossing, as it does not remove plaque. Furthermore, sweetened gum can be harmful and increase the risk of tooth decay. She stressed the importance of brushing twice daily and using gum only as a temporary solution when proper oral hygiene is unavailable.
For her part, neurologist Ekaterina Demyanovskaya explained that chewing gum activates sensorimotor networks in the brain and increases blood flow to the prefrontal cortex, which may temporarily improve attention and planning. She noted that neurological studies have shown an increase in brain oxygen levels, but these effects are short-lived and disappear after chewing stops.
She added that chewing gum may help with concentration on routine tasks or resist drowsiness during repetitive work, but it is not a substitute for rest and sleep, and may be distracting during tasks that require high concentration and short-term memory.
Experts warn against excessive gum chewing, as it can cause side effects such as tension headaches due to jaw muscle strain, or temporomandibular joint disorders that manifest as pain or clicking when opening the mouth. It is also not recommended for those suffering from teeth grinding, tooth erosion, or digestive problems.
They also pointed out that some gum ingredients, such as sorbitol or xylitol, may cause bloating or diarrhea if consumed in excess, and children who wear braces are advised to avoid them to prevent damage to the braces.
