If your child is always on top of their oral hygiene routine every day but is then diagnose with cavities, it could be from acid reflux. Gastroesophageal Reflux (GER) in infants, young children, and teenagers is more common than most parents think. Read on to learn more about how acid reflux can impact your child’s oral health and what you can do to help.

What is Acid Reflux?

Acid reflux is when food and acid from your child’s stomach rises back into their esophagus, causing an uncomfortable and burning sensation in the chest and throat. Some symptoms of acid reflux in children include:

  • Heartburn
  • Frequent burping and hiccups
  • Discomfort while swallowing
  • Nausea, especially after meals
  • An acidic, bad taste in the mouth
  • Not wanting to eat

Chronic acid reflux is something that babies, kids, and teenagers can experience, and while some may outgrow it over time, what many parents do not know is that it can have an impact on their child’s oral health as well as their daily comfort.

Connecting Acid Reflux & Oral Health in Kids

Enamel erosion, which is when the outer layer of the tooth is gradually deteriorated by acid, is often a consequence of acid reflux. When this happens, the subsequent underlying layer of the teeth, called the dentin, becomes exposed. This can lead to tooth sensitivity, discoloration, and an increased risk of cavities.

How to Take Care of Your Child’s Smile if They Have Acid Reflux

The key to helping maintain good oral health in children with acid reflux is being proactive to prevent enamel erosion and manage their symptoms. This includes collaborating with their pediatric dentist and pediatrician to make some changes to their diet, incorporating medications into their life, and helping them maintain a good oral hygiene habit at home.

Regular dental checkups and cleanings will allow their pediatric dentist to spot the signs of acid reflux early on. This way, they can recommend additional preventive dental treatments such as protective sealants and fluoride to help fortify enamel and counteract the raised risk of decay.

While many parents may not be aware of the impact that acid reflux can have on children and their oral health, it could be the reason why your child may be getting cavities despite having a good oral hygiene regimen. With guidance from your pediatric dentist and a plan in place to protect your child’s growing smile, you can rest easy.
