What causes tooth decay in children?

The risk of tooth decay in the case of children is more if compared to that in the case of adults. The reason behind this is pretty simple. The enamel layer is pretty soft on baby teeth which accentuates the chances of kids suffering tooth decay or cavities. But, adoption of a few measures, and gathering detailed knowledge about the topic can help you to prevent tooth loss of your child. Therefore, if you have any query related to tooth decay in children, do give the sections below a diligent read. 

Causes of Tooth Decay


Kids generally consume food products that have high sugar content. The bacteria present in the mouth thrive on the sugar from drinks and foods and produce an acid that damages the outer layer of their teeth which is termed as the enamel. If left ignored, the continuation of this process can lead to the creation of holes in your kid’s teeth and initiate the process of cavities. Saliva plays a vital role in fighting against the bacteria causing tooth decay. But if the amount of damage done is beyond repair, your child is bound to suffer from dental problems. 

It is to be noted that the process of tooth decay is also called “caries”. You might be able to spot white chalky areas on the kid’s teeth in the earlier stages of tooth decay. Later, these areas turn into black or brown spots on their teeth. Experts say that chances of suffering from caries are more in infants as they are often settled to sleep with a bottle of milk in their mouth. The milk can get accumulated in the kid’s mouth overnight while the bacteria and germs feed on the lactose sugar present in it. This leads to the growth of the bacteria and in turn paves the path for tooth decay. Children are also pretty much attracted towards sugary drinks, candies, soft drinks, and fruit juices that contribute to the cause. As a parent, you are advised to make your kid avoid consumption of such drinks, especially between having their meals.
