During pregnancy, all elective procedures such as teeth whitening should be avoided. However, does that same rule still apply when you’re breastfeeding? A lot of nursing mothers with newborns often ask if it is safe for them to whiten their teeth.
Our purpose here today is to explore every possible angle on this subject of whitening your teeth while you’re nursing. We’ll take into account what the ADA and ACOG have to say. Then we’ll present some relevant research studies as well as what the product labels on the whitening products say.
Finally we’ll give you a verdict on whether or not it is say to partake in this elective procedure and what you should do.
Guidance from the ADA
The American Dental Association (ADA) does not specifically mention teeth whitening while you’re breastfeeding. On the mouthhealthy website, their recommendation was to hold off on cosmetic procedures such as teeth whitening until after the baby arrives.
Even though they don’t specifically reference it, based upon what they said it should be safe to whiten your teeth while you’re breastfeeding. After all, when you are nursing it is after the baby has arrived.
Therefore, we can take that as the green light or go ahead from the ADA themselves to get that cosmetic procedure done. You’ve been putting it off for the past nine months and now is the time for your teeth to sparkle.
Guidance from the ACOG
The American College of Obstetricians and Gynecologists (ACOG) does not specifically mention teeth whitening at all in their guidelines. They do however state that all elective procedures should be postponed until after giving birth. From that we can infer that it is probably okay to do whiten your teeth while breastfeeding.
Other recommendations from ACOG guidelines:
- They say to reassure patients that x-rays and local anesthesia ARE safe during pregnancy.
- They also recommend to NOT delay treatment for any conditions which may require immediate attention. This includes extractions, root canals, and tooth restorations.
Basically they say that putting off needed procedures only results in more complex problems down the road.
American pregnancy association
The american pregnancy association does specifically say to postpone all elective dental treatment until after delivery. Since the whitening falls under cosmetic and consequently elective, we’ll infer that it means you’re probably clear to do it since you have already delivered the baby.
What do the product labels say?
For the over the counter products such as the Crest 3D white strips and the Opalesence Go, both of the product labels don’t mention anything about using it while breastfeeding nor pregnant.
We dug a little deeper and did find that KoR Whitening says that all nursing mothers should consult with their pediatricians prior to using whitening gels. They also said that pregnant women should NOT use their product at all.
Based upon that we would say that it is probably a hard NO for teeth whitening while pregnant. Although if you’re nursing it may be okay but you should consult with your child’s pediatrician if you’re still breastfeeding and you’re interested in whitening.
Research studies
All of the teeth whitening products are made with varying concentrations of hydrogen peroxide. Typically the over the counter products are of a lower concentration while the in-office are higher. If your product doesn’t have it, it is still an ingredient which is a derivative of hydrogen peroxide.
Unfortunately, there aren’t many actual studies on pregnant women and women who are nursing since that is a safety hazard and no one wants to volunteer for such studies. However, we can extrapolate and draw inferences from other studies about hydrogen peroxide itself.
According to PubChem, hydrogen peroxide is a category risk C drug. That means the risk cannot be ruled out because no actual studies have been done on pregnant women. However, it may be used if the benefits outweigh the risks.
If you were looking for some good news, there was a study by the NIH, which was exploring various whitening products on pregnant women. The hydrogen peroxide was tested on skin bleaching only and not teeth bleaching but their conclusion was that it was safe. Basically in LOW concentrations, the hydrogen peroxide gets rapidly detoxified and metabolized once it reaches the blood. Only trace amounts remain in the blood.
We just want to emphasize that the study said LOW concentrations of hydrogen peroxide because we found a LabChem SDS with hydrogen peroxide in the 30% concentration, which agreed. It explicitly said to avoid contact while pregnant and nursing.

Should you or should you not whiten your teeth while breastfeeding?
Taking into account all of the guidelines and research studies, it is most likely safe to whiten your teeth while breastfeeding. None of the organizations nor whitening companies said that you can’t do it. Only KoR whitening said that you should consult with your pediatrician but it didn’t say that you couldn’t do it.
Also based on research studies on hydrogen peroxide, it seems to be relatively safe in low concentrations because it gets detoxified and metabolized very quickly once it reaches your blood stream. However, higher concentration products you may want to be wary about but the good news is that you usually can’t purchase those OTC.
All of the over the counter products are typically lower in concentration so they’re probably the safest route to whiten your teeth if you’re nursing. The in-office products generally do come in a much higher concentrations.
Basically you’re probably safe to whiten your teeth while you’re breastfeeding if you’re going with any of the OTC products such as whitening toothpaste. Although you should probably still ask your pediatrician about the in-office whitening just in case.
However if you’re still pregnant you shouldn’t whiten your teeth. You must wait until after delivering the baby!
