Oral Health During HG

Repeated vomiting bathes teeth in stomach acid, and enamel does not grow back. Protecting your teeth is simple once you know how — keep this by the bathroom sink.

The one rule that surprises everyone

Do not brush your teeth right after vomiting. Acid softens enamel, and brushing immediately can scrub it away. Rinse first, wait, then brush.

After vomiting — in this order

Rinse with plain water, or water with a small amount of baking soda (about 1 teaspoon per cup) to neutralize the acid

Wait at least 30 minutes so enamel can re-harden

Then brush with a soft toothbrush and fluoride toothpaste

Every day

At night, smear a little fluoride toothpaste on your teeth and leave it (do not rinse) for extra protection

Stay as hydrated as you can — saliva protects teeth

If mint toothpaste triggers nausea, try unflavored or child-flavored fluoride toothpaste

Keep rinse water and a cup wherever you tend to be sick

Tell your dentist

That you are pregnant and have Hyperemesis Gravidarum

Ask: "What can we do now to protect my enamel?"

Ask: "Should I use a prescription fluoride rinse or varnish?"

Why it matters

Enamel erosion from HG can cause sensitivity, cavities, and lasting damage — but it is largely preventable with these steps. Your teeth are part of your health, and protecting them is part of HG care.
