Is Kids Toothpaste Safe?

📅 Updated February 2026⏱️ 5 min readNEW

TL;DR

Most conventional kids' toothpaste is not safe to swallow due to high levels of fluoride, artificial dyes, and harsh foaming agents. The FDA requires a poison warning on fluoride formulas because ingestion can cause dental fluorosis or acute toxicity. If your child hasn't mastered spitting, switch to a non-toxic hydroxyapatite toothpaste and strictly limit the portion size.

🔑 Key Findings

1

38% of children aged 3-6 use half or full brush loads of toothpaste, far exceeding the recommended pea-sized amount.

2

Children under six years old have poor swallowing reflexes and ingest a large percentage of the toothpaste they use.

3

Most mainstream kids' toothpastes contain Sodium Lauryl Sulfate (SLS), a harsh detergent linked to mouth ulcers.

4

Hydroxyapatite offers a safe, non-toxic alternative that remineralizes teeth without the risk of fluoride toxicity.

The Short Answer

Mainstream kids' toothpaste is a caution at best. While formulated with fun flavors to encourage brushing, most conventional brands are packed with artificial dyes and harsh foaming agents that shouldn't be swallowed.

The biggest concern is portion control combined with fluoride. According to the CDC, 38% of children aged 3 to 6 use too much toothpaste. Because young kids haven't mastered their swallowing reflex, this leads to chronic ingestion of ingredients that literally carry an FDA poison warning.

Why This Matters

Children under six swallow a massive percentage of whatever you put on their toothbrush. This makes the ingredient list of kids' toothpaste more akin to food than a topical treatment. If you wouldn't let them eat it, they probably shouldn't be brushing with it. Is Swallowing Toothpaste Dangerous

The CDC specifically warns about the dangers of excessive toothpaste use in young children. Swallowing too much fluoride during early childhood development leads to dental fluorosis, a condition that permanently discolors and pits the enamel of their adult teeth. Should Kids Use Fluoride Toothpaste

Most parents are simply using too much paste to begin with. A child under three only needs a smear the size of a grain of rice, while kids aged three to six should use no more than a pea-sized amount. How Much Fluoride For Kids

What's Actually In Kids Toothpaste

  • Fluoride — The active cavity-fighting ingredient in most mainstream brands. Because it is highly toxic when ingested, the FDA requires a mandatory poison warning on the tube. Fluoride Vs Fluoride Free For Kids
  • Sodium Lauryl Sulfate (SLS) — A synthetic detergent that creates the foamy lather we associate with being "clean." SLS is a known irritant linked to severe canker sores and microscopic tissue peeling in the mouth. Is Sls In Toothpaste Bad
  • Artificial Dyes — Ingredients like Red 40 and Blue 1 are used to make the paste look like candy. Dyes serve no dental purpose and have been linked to behavioral issues and hyperactivity in sensitive children.
  • Artificial Sweeteners — Saccharin and sucralose are heavily used to mask the bitter taste of chemical detergents. These synthetic sweeteners disrupt the oral microbiome and encourage a preference for highly sweetened products.

What to Look For

Green Flags:

  • Hydroxyapatite (n-Ha) — A naturally occurring mineral that makes up 97% of our tooth enamel. It remineralizes teeth just as effectively as fluoride but is 100% safe to swallow. Is Hydroxyapatite As Good As Fluoride
  • Xylitol — A natural sweetener that actually starves cavity-causing bacteria. Look for formulas where xylitol is one of the first ingredients.

Red Flags:

  • FDA Poison Warnings — If the tube tells you to call Poison Control upon swallowing, it is not safe for a toddler who can't spit.
  • Neon Colors or Sparkles — Bright blue, red, or sparkly pastes are a dead giveaway for artificial dyes. These serve no purpose other than marketing and should be strictly avoided.

2. Control the portion size. Never let a toddler apply their own toothpaste. Stick to a rice-sized smear for babies and a pea-sized drop for preschoolers. How Much Fluoride For Kids
