Most people know that using weight loss medication can throw up all sorts of side effects – some more sinister than others – but the latest health expert to weigh in has some surprising news
Interest in weight-loss jabs has never been higher, with 64 per cent of adults in England classed by the NHS as either overweight or obese. Scarily, a recent Numan State of Obesity Report shows that 26 per cent of us have learned about medications like Mounjaro and Wegovy through social media with only 7 per cent sourcing accurate information via a qualified GP.
It’s little wonder users are suffering nasty – and unexpected – side effects.
Millions of Brits are now eligible for the appetite-suppressing jabs which many already know, can come with unpleasant side effects, but NHS rationing means only a tiny fraction will be prescribed them.
This has led to huge demand for expensive private purchases of the weekly injections which slow digestion by mimicking a hormone called glucagon-like peptide 1 (GLP-1) which regulates hunger and feelings of fullness. Many patients have complained of side effects such as vomiting and stomach cramps and now a dental expert has weighed in with a new one to watch out for.

Speaking exclusively to the Mirror, Dr Dalel Trabelsi, a dentist and clinical lead at Tooth Club (www.toothclub.co.uk) has revealed that weight loss drugs have given dentists like him plenty of cause for concern.
He said: “Popular medications like Ozempic and Mounjaro are helping people shed pounds, but they’re also giving dentists like me plenty to talk about. There are health risks involved, not just for your body, but also for your oral health.”
He continued to explain how these medications can impact your teeth and smile and why your pearly whites might need some extra TLC if you’re using them.
“Many people are surprised to learn that weight loss medications can impact your teeth and gums in several ways. These effects often arise from changes in saliva production, nutrient absorption, and increased acid exposure,” he said.
“One major factor is how these drugs affect the nervous system, which can lead to reduced saliva production. Think of saliva as nature’s mouthwash. Saliva plays a crucial role in neutralising acids, washing away food particles, and keeping bacterial growth low.
“Having a dry mouth increases the risk of cavities, as saliva helps remineralise enamel, and it can also raise the chances of gum disease due to bacterial build-up.”
And it’s not just how your mouth health looks, either, says Dr Dalel. “Less saliva can also lead to bad breath. Staying hydrated is so important, and chewing sugar-free gum can help stimulate saliva production. It’s also a good idea to avoid any alcohol-based mouthwashes where possible, as they can be drying.
“Another issue is digestion. Many weight loss medications slow down the digestive system, which can lead to acid reflux. Nausea can also be another side effect, and vomiting exposes teeth to stomach acid, which can weaken enamel, cause decay, and lead to yellowing over time.”
Dietary changes affect oral health and although it’s obvious that appetites for those on weight loss medication will be reduced, this can also affect your teeth.
“This can lead to a lower intake of essential nutrients needed for healthy teeth and gums. Calcium and vitamin D deficiency can weaken teeth, a lack of vitamin C can contribute to gum inflammation and bleeding and low iron levels can also increase the risk of oral infections.”
There are ways to combat this though. “Try to maintain a balanced diet, even in smaller portions, and consider supplements to increase your nutritional intake. Some weight loss medications can also change how you taste certain foods, making certain foods less appealing. This may lead to people choosing more acidic, sugary, or processed foods, which can also be harmful to oral health.
“By staying mindful of these potential effects and making small adjustments, you can help protect your smile while on your weight loss journey,” said Dr Dalel.
Top takeaways to remember if you take these medications
- If vomiting does happen, resist the urge to brush immediately. Rinse with water first and wait 30 minutes to avoid scrubbing acid into your enamel.
- Oral hygiene is key: Brush twice daily with fluoride toothpaste and floss regularly.
- Consult your dentist: Let them know about any medications you’re taking so they can tailor care to your needs.
- Stay hydrated: Staying hydrated isn’t just good for your body, it’s essential for your teeth too.
With a little extra care and regular dental check-ups, you can stay on top of both your health goals and oral hygiene.
