Weight-loss medications such as Ozempic and Mounjaro may be helping millions shed pounds, but a dental expert has warned they could be wreaking havoc on oral health. With 64 per cent of adults in England classed as overweight or obese by the NHS, demand for appetite-suppressing jabs has soared, despite a recent report showing most people learn about them through social media rather than medical advice.
Dr Dalel Trabelsi, a dentist and clinical lead at Tooth Club, said the drugs can impact teeth and gums in several ways. One major concern is reduced saliva production, which acts as the mouth's natural defence against acids and bacteria. A dry mouth increases the risk of cavities and gum disease, and can also lead to bad breath, she explained.
The medications, which slow digestion by mimicking the hormone GLP-1, can also cause acid reflux and nausea. Vomiting exposes teeth to stomach acid, which can weaken enamel and lead to decay and yellowing over time. Changes in diet, including lower intake of essential nutrients like calcium, vitamin D, and vitamin C, may further harm oral health.
Dr Trabelsi advised those using weight-loss jabs to stay hydrated, chew sugar-free gum to stimulate saliva, and avoid alcohol-based mouthwashes. She also recommended maintaining a balanced diet, considering supplements, and keeping up with regular dental check-ups to protect their smile.
