Standard fluoride toothpaste is safe during pregnancy and is actively recommended by both the American Dental Association (ADA) and the American College of Obstetricians and Gynecologists (ACOG). You don’t need a special “pregnancy toothpaste,” but there are a few ingredients worth understanding and some that are worth avoiding.
Fluoride Toothpaste Is the Standard Recommendation
The ADA specifically recommends that pregnant people brush twice a day with fluoride-containing toothpaste and a soft-bristled brush. This isn’t a cautious compromise. The ADA’s official position is that preventive, diagnostic, and restorative dental care is safe throughout all stages of pregnancy. ACOG agrees.
The amount of fluoride in a standard toothpaste (typically 0.15% or about 1,000 to 1,500 parts per million) is far below the levels that have raised concerns in research. A 2023 review by the National Toxicology Program found that fluoride exposure above 1.5 milligrams per liter in drinking water was associated with lower IQ in children, but the program noted there was insufficient data to determine whether the much lower levels used in U.S. water fluoridation (0.7 mg/L) posed any risk. Since you spit toothpaste out rather than swallow it, the actual fluoride you absorb from brushing is minimal.
If morning sickness makes brushing difficult, fluoride varnish applied by your dentist is another option. Dental professionals sometimes prefer varnish over gel treatments for pregnant patients because it’s less likely to trigger nausea.
Ingredients Worth Avoiding
Triclosan
Triclosan is an antimicrobial agent that was once common in toothpaste and soaps. It acts as an endocrine disruptor, meaning it can interfere with hormones, particularly estrogen, androgen, and thyroid function. Research in humans has linked higher urinary triclosan levels to increased risk of spontaneous abortion, reduced birth weight, shorter birth length, and smaller head circumference. The FDA has been tightening restrictions on triclosan over the years. Most major toothpaste brands have already removed it, but it’s still worth checking labels, especially on store-brand or imported products.
Parabens
Methylparaben and propylparaben are preservatives found in some personal care products, including certain toothpastes. Like triclosan, parabens have estrogenic activity and are classified as endocrine-disrupting chemicals. Prenatal paraben exposure has been linked to changes in birth weight. While concentrations in toothpaste are small, choosing paraben-free products during pregnancy is a simple way to reduce one more source of exposure.
Hydrogen Peroxide and Whitening Agents
Professional-strength whitening treatments use hydrogen peroxide or carbamide peroxide, and few studies have evaluated their safety during pregnancy. Some product manufacturers explicitly caution against use during pregnancy, and the concern centers on the potential for swallowed chemicals to affect the fetus. Most dentists recommend postponing bleaching treatments until after delivery. If you want a brighter smile in the meantime, a standard whitening toothpaste (which uses mild abrasives rather than high concentrations of peroxide) is generally considered a safer middle ground.
SLS and Pregnancy Mouth Sensitivity
Sodium lauryl sulfate (SLS) is the foaming agent in most toothpastes. It’s not harmful to your baby, but it can make pregnancy-related mouth discomfort worse. SLS breaks down the protective barrier of your oral tissue, which can lead to peeling of the inner cheeks, swelling, and canker sores. Pregnancy already increases blood flow to your gums and makes oral tissue more sensitive, so if you’re dealing with sore gums or recurring mouth ulcers, switching to an SLS-free toothpaste may help. Studies on people prone to canker sores found that SLS-free formulas reduced the number of ulcers, how long they lasted, and how much they hurt.
Hydroxyapatite as a Fluoride Alternative
If you’d prefer to skip fluoride entirely, hydroxyapatite toothpaste is the most evidence-backed alternative. Hydroxyapatite is a form of calcium phosphate that makes up about 97% of your tooth enamel. When applied as a toothpaste, it fills in microscopic damage on the tooth surface and helps remineralize weakened areas, similar to what fluoride does but through a different mechanism. No adverse health events have been reported with hydroxyapatite toothpaste in clinical studies, and it carries no risk of fluorosis (the mottled discoloration that can happen with excessive fluoride in young children).
Hydroxyapatite toothpaste is widely used in Japan, where it has been an approved anti-cavity ingredient since the 1990s. It’s increasingly available in the U.S. and Europe, though it tends to cost more than standard fluoride toothpaste. For pregnant people who experience nausea from the taste of fluoride toothpaste or who simply want to minimize chemical exposure, it’s a reasonable choice with a strong safety profile.
What to Look for on the Label
- Use: Fluoride toothpaste (sodium fluoride or stannous fluoride) or hydroxyapatite toothpaste
- Avoid: Triclosan, listed as “triclosan” or sometimes “Irgasan”
- Avoid: Parabens, listed as methylparaben, propylparaben, or butylparaben
- Optional swap: SLS-free if you have mouth sores or gum sensitivity
- Postpone: High-peroxide whitening products until after delivery
Pregnancy changes your mouth in real ways. Higher hormone levels make gums more prone to inflammation, and frequent vomiting exposes teeth to stomach acid that erodes enamel. Consistent brushing with a safe toothpaste matters more during pregnancy than at almost any other time. The good news is that the vast majority of toothpastes on store shelves are perfectly fine to use. A quick scan of the ingredient list for the few problematic compounds listed above is all most people need to do.
