Can hot weather hurt teeth? Summer survival tips.
Feeling the heat? With record May temperatures reported, our dental health may not be our first concern. Extreme hot weather can have a serious impact on some people’s health, and for many of us it’s uncomfortable.
Extreme weather is a warning we take seriously and we urge everyone to keep safe too. It’s easy to underestimate the impact a heatwave can have on the health of vulnerable people. High temperatures can be damaging, even deadly, exacerbating other symptoms and leading to accidents particularly beside water. There are precautions we can take to protect ourselves, and the people we care for, from heat-stress and related complications. We need to keep cool, go outdoors at sensible times, with sun-screen, protective clothing and water.
In addition, as far as our oral health is concerned, an extended spell of warm weather can have a negative impact on our teeth. It’s good to be aware too that there is also some risk to our dental health. It’s not that hot weather itself hurts teeth, but what we put our teeth through when the temperatures rise can cause damage.
Hot weather itself isn’t the problem
The problem for teeth is more to do with the drinks and food we enjoy during a heatwave. There are three main dangers:
Temperature changes can cause tooth enamel to crack. A sudden temperature change causes thermal shock. Even gradual temperature changes cause the dentine and the enamel to expand and contract at slightly different rates. Over time, teeth will feel more sensitive and look more stained.
Whether it’s in ice-cream or a cold latte, sugar hurts teeth. Bacteria love sugar, and the longer your mouth stays sweet, the more bacteria can flourish.
Acid found in fizzy drinks, fruit juices and wine, for example, weakens tooth enamel allowing bacteria easier access to underlying tooth structures. Saliva helps to neutralise acid.
Don’t let hot weather hurt teeth:
Allow very cold drinks to lose the brain-freeze factor.
Drink water regularly to encourage salivation.
Plain milk is a healthy option.
Make your own frozen yoghurts, sorbets or ices so you know the ingredients.
Avoid, or limit, acidic fruits and drinks that erode enamel.
Use a straw to keep damaging ingredients away from teeth.
Keep up the minimum twice-daily oral hygiene routine.
