Trick or Teeth? How to Keep the Sweet Stuff from Turning Scary

Halloween night can leave children with a bucket full of sweets and a lot of sugar to work through. With a few simple swaps and some good habits, parents and carers can let little ones enjoy the fun while keeping their teeth protected.

Pumpkins are glowing on doorsteps up and down the street, and before long a crowd of pint sized witches, ghosts and skeletons will be knocking on doors in search of the one thing every child is after: sweets. It is all part of the fun, but it is also easy to lose sight of just how much sugar can disappear in a single evening. Some of the worst culprits pack in as much as 17g of sugar in one handful.

So when the treats start piling up, which ones are worth keeping and which are best left out of the bucket?

The treats to think twice about

Hard boiled and sticky sweets sit near the top of the list for causing trouble. They are high in sugar and linger in the mouth for longer, which means teeth are exposed to more acid that can gradually wear away enamel. Biting down on a hard sweet can also chip a tooth, which is the last thing anyone wants on a night out.

Sour sweets are another one to watch. Their high acid content can lead to sensitivity and raise the chance of cavities, and they can even affect taste buds.

Better choices for the bucket

Hygienist Emma Nelson suggests reaching for lower sugar alternatives such as jelly sweets and yoghurt coated fruit. Popcorn with a drizzle of chocolate is another option that still feels like a treat while being a little kinder to teeth.

She says: “Children can still enjoy their treats but it’s vitally important to be aware of how much sugar they are consuming and the potential impact on their teeth. My advice is to limit extra sugar intake from sweets to no more than 19g a day for children aged four to six, which is roughly the equivalent of 5 sugar cubes. For children aged seven to 10, the daily limit is 24g, or around 6 sugar cubes.”

Emma’s five tips for Halloween and beyond

Make sure children brush twice a day using a fluoride toothpaste.

Wait at least 30 minutes after eating anything acidic before brushing, so the enamel is not worn down while it is softened.

Cut back on sugary snacks and drinks, and offer healthier alternatives such as a colourful fruit skewer or a bowl of popcorn.

Start cleaning between the teeth once two teeth are touching, usually somewhere between the ages of two and six, and encourage children to do this once a day.

If sweets are on the menu, it is better to enjoy them in one go rather than grazing throughout the day, as this limits how often teeth come into contact with acid.

Don’t forget the gaps

Most tooth decay actually begins between the teeth, yet a toothbrush on its own only reaches around 60% of the tooth’s surface. That leaves plenty of space for food and plaque to build up, which is why cleaning between the teeth matters so much. Dentists advise starting this habit as soon as two teeth are touching. Because standard floss can be tricky for small hands, products made specifically for children tend to work better, and child friendly options such as DenTek’s Kids Fun Flossers can be brought into the routine from an early age.

With a little planning, there is no need to let sugar have the final scare this Halloween. Children can enjoy their haul, and their smiles can come out the other side just as bright.
