Summer is the season of iced coffees, sizzling barbecues and frozen treats – but these warm-weather favourites can have hidden consequences for your teeth and gums. Miranda Pascucci, Head of Clinical Education and Dental Therapist at TePe, shares the biggest seasonal culprits and how to enjoy summer without putting your smile at risk.
“Some of the most popular summer treats are high in sugar, acid, or both – the perfect recipe for dental trouble if consumed too often,” explains Miranda. “Sugary cocktails, sticky BBQ sauces and acidic fruit can all weaken enamel and feed harmful bacteria.
Sugary drinks
“Fizzy drinks, sweet cocktails, fruity ciders… all of these are summer staples, but can contain high amounts of sugar. After drinking sugary drinks, the molecules combine with saliva and bacteria present in the mouth. This combination leads to plaque build-up on the teeth. When left on the teeth, plaque can weaken the tooth’s enamel, which can lead to cavities and also, gum disease.
“It’s not about cutting sugary drinks out entirely, but being aware of how they interact with your mouth. The frequency and the length of time that sugary drinks are in contact with your teeth makes a big difference to your oral health. If possible, consume in moderation and try to drink with meals. You can also rinse the mouth with water afterwards to neutralise the acid and stimulate saliva production.”
Cold drinks and ice cream
“Frozen drinks, iced coffees and ice cream sound appealing on a hot day, but for those with worn enamel or exposed dentine, they can trigger sensitivity and cause pain. The sudden temperature change from very cold foods or drinks can trigger sharp, shooting sensations in the teeth – a sign that the protective enamel layer has thinned and the dentine underneath is exposed.
“Over time, repeated exposure can make sensitivity worse, as weakened enamel is less able to protect the tooth’s inner structure. This is why it’s important to manage the underlying cause of sensitivity with the help of your dental professional, and to take steps to protect your enamel – such as avoiding overly aggressive brushing, reducing acidic food and drink intake, and maintaining a thorough daily oral hygiene routine including interdental cleaning.”
Sweet marinades and acidic dressings
“Many of us love a refreshing salad on a hot summer’s day, and of course, the Great British Summer isn’t complete without a barbecue! However, the acidity of salad dressings and hidden sugar in marinades can wreak havoc on our oral health if not consumed mindfully. Acidic dressings – especially those made with vinegar or citrus – can gradually soften the enamel surface, making it more vulnerable to staining, wear and decay.
“Marinades often contain syrups, honey or other sugars that caramelise during cooking. This sticky layer can cling to tooth surfaces and between the teeth, providing a food source for bacteria long after you’ve finished eating. If particles remain trapped in hard-to-reach areas, they can contribute to plaque build-up and increase the risk of gum inflammation. Enjoying these in moderation, rinsing with water afterwards, and removing debris with an interdental brush can help keep your teeth fresh and protected, even during the most flavour-packed summer feasts.
“No matter what you eat, it’s vital maintain a thorough oral health routine to minimise the impact on the teeth. Brushing with a toothbrush alone only cleans 60% of the tooth’s surface – leaving 40% unbrushed, causing plaque build-up which can lead to gum disease. For optimal oral health, you must brush the teeth twice a day with a toothbrush and toothpaste containing 1350 -1500 PPM, and clean between the teeth at least once a day using floss or a TePe interdental brush.”
