Your dental habits could be making you gain weight, claims oral surgeon
January is often the month where people try to change their lifestyle. Between Dry January, Veganuary, and 75 Hard, there are various initiatives designed to help people feel happier and confident in themselves and their bodies.
Many factors inform weight gain. The most important thing is that you're healthy, but for those who do care about the number on the scales, fast food, fizzy drinks, and a lack of exercise can hinder your ability to shed the pounds.
However, it turns out oral hygiene has a part to play, too, according to experts. They claim looking after your teeth can improve gut health, overall wellbeing, and even help with weight loss for those struggling to shift a few pounds.

"The mouth is the gateway to the body," Dr Andrej Bozic of Dentum explained. "What happens here can influence the rest of your system, including the delicate balance of bacteria in your gut."
The dental expert explains the oral-gut health connection and how to get on top of it in great detail. He says that poor oral hygiene can lead to an overgrowth of harmful bacteria in the mouth.
These bacteria can be swallowed, travelling to the gut, where they disrupt the microbiome - the collection of microorganisms essential for digestion, nutrient absorption, and immunity.
"When oral bacteria like Fusobacterium nucleatum migrate to the gut, they can create an imbalance, leading to inflammation and poor digestion," Dr Bozic warned.
This can manifest in various ways, from bloating and fatigue to skin breakouts and difficulty managing weight. In terms of gut health, improved oral hygiene reduces harmful bacteria and supports a healthy gut microbiome.
Dr Bozic shares how you can step up your oral care routine:
Brush twice daily: Use fluoride toothpaste and brush for two minutes to remove plaque and bacteria.
Floss daily: Flossing clears food particles and bacteria from hard-to-reach spaces between teeth.
Use antibacterial mouthwash: A quality antibacterial rinse helps reduce harmful microbes and freshens your mouth.
Stay hydrated: Water boosts saliva production, neutralising bacteria and aiding digestive health.
Eat a balanced diet: Include probiotics (yoghurt, fermented foods) and prebiotics (fibre-rich veggies) to nourish both oral and gut microbiomes.
By enhancing your oral hygiene, you reduce systemic inflammation, promote better digestion, and improve nutrient absorption - all of which can contribute to glowing skin and healthier weight management.
"The mouth often reflects what’s happening in the body," the oral surgeon added. "If you pay attention to it and maintain excellent oral hygiene, you’re setting the stage for improved gut health and overall vitality.
"So, the next time you’re brushing your teeth, remember: You're not just protecting your smile - you're investing in your whole-body health."
