Why Your Child May Have More Cavities Than Usual

If you have noticed that your child has more cavities than usual, you may be wondering what is causing this problem and how to prevent it. Cavities are holes in the enamel of the teeth that are caused by oral acids. Bacteria feed on sugars and starches in the food and drinks that your child consumes and produce acids that dissolve the enamel. Over time, this can lead to tooth decay and infection.

In addition to poor oral hygiene, there are many factors that can increase the risk of cavities in children. Here are some of them.


Sugary and starchy foods and drinks can fuel the growth of bacteria and increase the acidity of the oral cavity. This can weaken the enamel and make it more prone to cavities.

Children should limit their intake of candy, cookies, cakes, soda, juice, and other sweetened beverages. They should also avoid snacking frequently between meals, as this can expose the teeth to more acid attacks. Instead, they should eat a balanced diet that includes fruits, vegetables, whole grains, dairy products, lean protein, and water.

Dry Mouth

Saliva plays an important role in protecting the teeth from cavities. It helps wash away food particles and bacteria, neutralize acids, and remineralize the enamel. Dry mouth occurs when there is not enough saliva in the mouth.

Some children may have dry mouth due to certain medications, medical conditions, or breathing through the mouth. Dry mouth can increase the risk of cavities. Children with dry mouth should drink plenty of water throughout the day, chew sugar-free gum, or candies to stimulate saliva production, and use a humidifier at night to moisten the air.


Some children may be more susceptible to cavities than others due to their genetic makeup. For example, some children may have softer or thinner tooth enamel, which can make it easier for bacteria to penetrate the tooth material.

In addition, some children may have deeper grooves or pits in their molars, which can trap food and bacteria more easily. Children with these characteristics should be extra careful with their oral hygiene and diet and may benefit from dental sealants or fluoride treatments to help protect their teeth.

Cavities can cause pain, sensitivity, infection, and tooth loss if left untreated. Therefore, it is important to treat them as soon as possible.

If you notice any signs of cavities in your child's teeth, such as white spots, brown spots, or holes, contact a general dentistry clinic.
