If you’re a breastfeeding first time mom, you may wonder if teeth whitening is safe.

After all, everything you put in your body has the potential to pass to your baby.

So, what do you do if you want a brighter smile?

Here’s everything new moms and pregnant women should know about teeth whitening, plus other helpful tips and resources!

What is teeth whitening?

Before we discuss teeth whitening and breastfeeding, it’s important to understand the process and products involved.

Teeth whitening is a simple treatment that uses chemical reactions to achieve whiter teeth. And there are two types of products that may be used: bleaching and non-bleaching.

Bleaching products include the active ingredient hydrogen peroxide and/or carbamide peroxide.

Peroxide-based ingredients have strong oxidizing properties that correct tooth discoloration.

These bleaching agents work well for surface-level stain removal. And they also remove deeper stains under the tooth enamel that cause our natural teeth to become discolored.

Other non-bleaching teeth whiteners simply remove food and debris from the teeth.

Common Teeth Whitening Products and Methods

You can get professional whitening services from your dentist or licensed estheticians. Or, you can purchases bleaching and whitening products over the counter.

However, the products dentists use have much higher concentrations of hydrogen peroxide. So, they’re more effective.

Here are some of the most common teeth whitening products and methods.

At the Dentist (or Esthetician)

The whitening process usually starts with a light cleaning. And then they’ll apply a whitening gel to the teeth.

They’ll then focus ultraviolet lights on your teeth to speed up the chemical reaction of the whitening gel ingredients.

Home Kits

Teeth whitening kits that you use at home, may include custom trays for your teeth and an assortment of whitening products.

These may include items like whitening strips, a teeth whitening pen, and whitening toothpaste.

Home kits usually come with instructions for a daily routine. And you should follow these steps until you achieve your desired results, or until you run out of supplies.

Other Methods and Products

Many regular toothpaste products in the supermarket advertise whitening properties that may help to brighten your smile. However, these are usually stain-reducing, rather than truly whitening.

There are also a few controversial home methods that many swear by. But, they may not yield results, and some can actually harm your teeth.

One of those methods is oil pulling. Believers claim that swishing coconut oil in the mouth for extended periods of time can pull bacteria and other contaminants from your teeth, which is likely true.

But, there isn’t scientific evidence to prove that coconut oil improves the color of teeth.

You may also be tempted to try activated charcoal products. But there isn’t much proof that these items whiten teeth either. They may actually cause permanent damage.

These abrasive products may expose the yellow dentin below the tooth enamel, and they may also increase the surface roughness of teeth.

This may also make it easier for bacteria to cling to teeth and cause cavities or tissue damage.

How long does it last?

Teeth naturally yellow over time, so teeth whitening isn’t permanent. However, proper maintenance will prevent premature yellowing.

For best results, practice good oral hygiene.

This includes regular dental appointments, brushing, and flossing. And you can also incorporate safe teeth whitening products into your daily routine.

Can I whiten my teeth while breastfeeding?

As most know, breast milk is produced in the mammary glands. Those glands take essential nutrients and chemicals from the mother’s body for her growing baby.

There are plenty of substances a lactating mother should avoid like nicotine and certain medications.

But, the chemicals used to whiten teeth are just fine!

Teeth whitening is completely safe for breastfeeding moms. The peroxide used for in-office whitening and take-home kits doesn’t absorb into the bloodstream and therefore doesn’t end up in breastmilk.

If you inevitably swallow a small amount of peroxide, it will quickly metabolize. So it won’t pose a risk to your breastmilk.

But, even though teeth whitening is considered safe for breastfeeding moms, you should always consult with your doctor before starting new procedures or medications.

Teeth Whitening While Pregnant

While it’s likely safe for pregnant women to get their teeth whitened, it’s not recommended.

The American Dental Association recommends that non-essential office procedures and dental work be differed until after pregnancy.

These procedures typically won’t harm an unborn baby but may hurt the mother’s oral health.

Many pregnant women experience changes to their teeth which may cause, tooth sensitivity (and sometimes unbearable tooth pain), gum irritation, and even pregnancy gingivitis.

Teeth whitening and other cosmetic procedures may worsen these conditions.

Because of that, most dental professionals hold off on teeth whitening to minimize these potential risks.
