If you think protecting your teeth is all about brushing twice a day with daily flossing, you might be missing a bigger piece of the puzzle. According to one dentist, what you eat could play a crucial role in keeping your teeth strong - and some of the most effective options cost less than £2.
Bone Health and Teeth: The Hidden Connection
While many people are familiar with conditions like osteoporosis, fewer realise that a similar weakening process can affect their teeth and jaw over time. Years of daily wear, combined with poor nutrition, can leave teeth more vulnerable - but small changes to your diet could help protect them. Dr Andrej Bozic, an oral surgeon at Dentum, said: “Your teeth and jawbone rely on the same minerals as the rest of your skeleton. If your bone health declines, it can affect everything from tooth stability to long-term oral health.”
He added that while calcium is essential, it is not the only nutrient that matters. Other vitamins and minerals also support bone density, meaning a more varied diet can make a real difference over time.
Sardines: A Cheap Superfood for Teeth
Often overlooked, sardines are one of the cheapest and most nutrient-rich options available. Tins can cost under £1 in many supermarkets, making them an accessible choice. Dr Bozic said: “They provide calcium, vitamin D and omega-3 fatty acids, all of which support bone density. These nutrients also help reduce inflammation, which can impact both bone and gum health.”
Prunes: An Unexpected Ally for Bone Density
Prunes may not be the first thing that comes to mind for dental health, but research suggests they can play an important role in maintaining bone strength. Eating around five to six prunes a day has been linked to preserving bone density, particularly in older adults. However, their natural sugar content means they should be eaten in moderation. “Prunes contain compounds that appear to support bone metabolism,” Dr Bozic said. “They’re a simple addition that many people wouldn’t immediately think of.”
Tofu: A Plant-Based Calcium Powerhouse
Tofu is widely known as a staple in plant-based diets, but it is also a valuable source of calcium and protein. “It’s an excellent option for those who don’t consume dairy,” Dr Bozic explained. “It delivers calcium alongside protein, both of which are important for strong bones and teeth.”
Beyond Diet: Other Factors in Oral Health
Experts stress that while these foods can support dental and bone health, they are only part of the picture. Lifestyle factors such as exercise, smoking, alcohol intake and underlying health conditions - including diabetes - can all influence long-term outcomes. Other issues, such as teeth grinding and dry mouth, can also contribute to weakening over time. In short, while there is no single fix, adding a few affordable, nutrient-rich foods to your diet could be a simple step towards stronger teeth and better overall health.
