Chewing gum is a habit we often do in daily life. However, it can create confusion about its effects on dental health. So, is chewing gum beneficial or harmful to our teeth?
In this week’s article, I will talk about 2 benefits and 2 possible harms of chewing gum.
- Increases Saliva Flow
Chewing sugar-free gum neutralises acids in the mouth by increasing salivation. This provides natural protection against tooth decay. In addition, saliva contains minerals that strengthen tooth enamel, helping to keep teeth healthier.
- Reduces Mouth Odour
Chewing gum is especially effective in eliminating bad breath after eating. Chewing gums containing mint or menthol provide a fresh breath by suppressing bad odours in the mouth. It also creates a healthier oral environment by reducing the accumulation of bacteria on the tongue.
- May Lead to Jaw Problems
Chewing gum for a long time and frequently can cause jaw joint (TMJ) problems. Especially in people with unilateral chewing habits, overload and pain may develop in the jaw muscles. It can cause jaw joint disorders, headache and facial pain.
- Gum containing sugar increases the risk of caries
Sugary chewing gums increase the risk of caries by triggering the formation of acids that damage tooth enamel. When chewing gum, the sugar stays on the teeth for a long time, creating a suitable environment for the growth of bacteria. For this reason, sugar-free chewing gum should be preferred.
As a result, chewing gum can be beneficial when done correctly, but excessive consumption or sugary gums can negatively affect dental health.
In addition, if you do not like sugar-free gum and do not want to chew sugary gum, you can choose gum with artificial sweeteners. Thanks to their 5-carbon sugar structure, these sweeteners make an extra contribution in preventing caries formation and reducing the activity of bacteria.
