Why does my child have bad breath?

Dr. Tahir Shahnawaz2 Oct 2023

Moms and Dads, let's talk about something some of us may have encountered: bad breath in our children. Bad breath is not unusual, but as parents, we understand the concern. In most cases, bad breath in children can be attributed to the following factors:

Transitioning teeth

Children often get bad breath when their teeth are “changing”. During the period where they gain and lose teeth, usually between the ages 2 and 12, their gums are loose and small food particles often get lodged in those loose gums. When their teeth and gums are not kept clean, these trapped food debris will rot and give off unpleasant odors. Regular brushing and flossing are important ways to prevent bad breath in our little ones.

Cavities and tooth decay

Cavities in a child's teeth also contribute to bad breath. Food particles can become trapped in these “holes”, leading to bacterial growth and an unpleasant smell. It's crucial to address decayed teeth promptly by cleaning and restoring them.

Sulphur-producing bacteria

Certain types of bacteria in the mouth are capable of producing sulfur compounds, which can result in foul-smelling breath. Maintaining good oral hygiene practices is the key to controlling these bacteria and preventing bad breath.

What causes cavities in babies and children?

Frequent breastfeeding and night-time feeding can lead to decalcification or cavities in babies' teeth.
High sugar intake of sugary drinks including juices and milk, and treats such as candies, toffees, and other refined carbohydrates are the main foods that cause tooth decay.
Poor oral hygiene habits encourages the growth bacteria which produce acids that attack the teeth.
Lack of regular dental visits. Routine check-ups allow your child’s dentist to put preventive measures into place.

How can we prevent cavities and bad breath in children?

Be mindful of your child’s diet and frequency of snacking. Limit sugar-rich foods and drinks. It is safer to consume sugary or starchy foods with main meals when saliva production is at its highest.
Take charge of your child’s oral hygiene. Brush your child’s teeth with a fluoride toothpaste twice a day and start flossing as soon as two teeth touch.
Avoid nighttime feeding. Do not put your baby to sleep with a bottle filled with breastmilk, formula, or juice.
Take them to the dentist regularly. Like adults, our little ones need regular dental care. Routine check-ups and cleans are a proactive step in preventing dental problems and ensuring their smiles remain bright and healthy.
