What causes tooth cavities in children?

How come my child had a cavity – when they brush every day?

If your pediatric dentist just told you that your child has a cavity, it can come as a bit of a shock! As parents, we like to think that we’ve educated ourselves on the importance of care during kids teething. However, cavities happen more often than you might think. Here are some tips to help avoid it.

Correct brushing

Cavities are caused by tooth decay. Tooth decay can have a few different causes, but it’s most often due to a build-up of bacteria and plaque that hasn’t been removed with proper tooth brushing. Brushing teeth is a routine that all children should have. Brush for two minutes, morning and evening, with a toothbrush and fluoride toothpaste. Ask your pediatric dentist for advice on the best children’s toothpaste. Use a very small amount at first, increasing to a pea-sized amount when they reach three years of age. If your child doesn’t like brushing their teeth, you can use music and dance to make it into a fun routine. Let your child see you brush your own teeth also, so they want to do the same.

Meals and snacks

It’s also important to consider how that troublesome bacteria and plaque might have built up in your child’s mouth in the first place. The usual culprit here is sticky foods and sugary snacks! Sweets, chocolate and fizzy drinks are the obvious ones to avoid. However, you might not know that fruit juices and milk can also cause problems. That’s because these still contains sugars that turn to acid in the mouth, and damage the enamel on the teeth – even if the milk or juice is diluted. The best drink is always water. Bread and cereals are also problematic, this time because they contain starches that then get converted to sugars in the mouth. It’s best to make sure your child has a varied diet, and make it rich in vegetables in particular, as these are naturally low in starches and also help actually clean teeth.

How to avoid problems

One important and often-overlooked factor in good dental health is saliva. Saliva performs magic – not only does it help rinse detritus from the mouth, it also contains enzymes that help neutralize problem-causing acid. Make sure your child drinks enough water during the day, and if they are young enough to want a bottle at night, make it water rather than milk. Brush regularly, and you can also encourage your child to floss once they are old enough to manage it themselves. Kids teething should also be managed by making an appointment to see the best pediatric dentist in Dubai – such as Drs. Nicolas & Asp – as soon as the first tooth emerges!

Treatment options

If you think your child has a cavity, you might notice a light brown patch on the tooth. If it’s a deeper cavity, it could be a darker shade or even black. Very early decay can appear as white spots on the tooth, as enamel is breaking down. Whether you can see any colour change or not, if your child has any tooth sensitivity to hot or cold, discomfort, or pain, you should see your pediatric dentist such as Drs. Nicolas & Asp, in case immediate tooth decay treatment is needed. All children are different, and not all cavities act in the same way. The pediatric dentist will perform an exam of your child’s mouth and may need to check their dental history also. They may also need to take X-rays to check the extent of the decay.

Tooth decay treatment will usually involve removing the decay and replacing the part of the tooth with a filling. It will be done under anesthesia so your child doesn’t feel anything. Fillings can usually be done in one single visit.
