Swallowing a small amount of TheraBreath mouthwash, like the amount you’d use during a normal rinse, is unlikely to cause serious harm. You might experience mild nausea or a brief upset stomach, but most people who accidentally swallow a mouthful recover without any problems. The risk increases with larger amounts, and the concern is greater for young children due to their smaller body weight.
A Sip vs. a Large Amount
TheraBreath products contain sodium chlorite and chlorine dioxide at very low concentrations. Because these ingredients are so dilute in commercial mouthwash, an accidental swallow typically causes nothing beyond mild irritation, nausea, and short-term vomiting. Most adults who swallow a single mouthful during rinsing won’t notice any symptoms at all.
Larger amounts are a different story. In significant quantities, sodium chlorite can damage red blood cells, making them unable to carry oxygen properly. This can lead to two serious conditions: one where red blood cells break apart faster than your body can replace them, and another where your blood loses its ability to deliver oxygen to tissues. These outcomes require drinking far more than a mouthful, but they illustrate why the product label says “do not swallow.”
What Symptoms to Watch For
After swallowing a small amount, you might notice mild stomach discomfort or nausea that passes within an hour or so. If a larger quantity was swallowed, symptoms can escalate to abdominal pain, diarrhea, vomiting, dizziness, drowsiness, or a headache. In rare cases involving very large ingestions, more serious signs include slurred speech, rapid heart rate, shallow breathing, low blood pressure, and uncoordinated movement.
Some TheraBreath formulas also contain fluoride. The Healthy Gums toothpaste, for instance, includes stannous fluoride at 0.454%. Swallowing fluoride in amounts beyond what’s used for normal brushing or rinsing can cause nausea, vomiting, diarrhea, and in more extreme cases, problems with electrolyte balance in the blood. Again, the amount matters: a small accidental swallow is very different from drinking the bottle.
Why Children Are at Higher Risk
The American Dental Association recommends that children under 6 should not use mouthwash at all, partly because young kids tend to swallow rather than spit. A volume that barely registers for an adult can be significant relative to a small child’s body weight. If a child drinks TheraBreath mouthwash, rinse their mouth out with water and make sure they’re not coughing or choking. Note the exact product name and try to estimate how much was swallowed, then contact Poison Control.
What to Do After Swallowing It
For a single accidental mouthful, rinse your mouth with water and wait. If you feel fine after 30 to 60 minutes, you’re almost certainly in the clear. Don’t try to make yourself vomit, as this can cause additional irritation to your throat and esophagus.
If you or your child swallowed more than a normal rinse amount, or if symptoms like persistent vomiting, dizziness, or drowsiness develop, contact Poison Control at 1-800-222-1222 or use their online tool. Have the product bottle nearby so you can read off the exact ingredients and concentration. TheraBreath’s own label directs users to get medical help or contact Poison Control if more than the amount used for rinsing is accidentally swallowed.
TheraBreath vs. Alcohol-Based Mouthwashes
One factor working in your favor is that TheraBreath is alcohol-free. Many conventional mouthwashes contain ethanol at concentrations that can cause intoxication if swallowed in large amounts, with symptoms ranging from nausea and vomiting to drowsiness, coma, and dangerously slow breathing. Because TheraBreath skips the alcohol, you don’t face that particular risk. The primary concern with TheraBreath is the chlorine dioxide and sodium chlorite, which at the diluted levels in the product pose minimal danger in small, accidental amounts.
