Can Activated Charcoal Really Whiten Your Smile?

If you’ve recently typed “how to whiten my teeth” into your favorite internet search bar, you may have discovered some strange results. For instance, pictures of people smiling while smearing a dark colored substance all over their teeth. Lately, using activated charcoal as a teeth whitening treatment has become very popular on social media. But does using this black mineral to brighten your smile really work?

How Does Activated Charcoal Work?

Activated charcoal has been heated up by a gas, which created large pores on its surface. When placed on your teeth, these pores latch onto rough spots, which are usually caused by plaque, tartar, or surface stains. After the activated charcoal has stayed in contact with your teeth for a few minutes, removing it will also clear away the yellowing agents it has bonded to. While it hasn’t earned a Seal of Approval from the American Dental Association, many people rave about how well this mineral works as a teeth whitening treatment.

Is Activated Charcoal Safe to Use?

This odorless and tasteless mineral can be purchased at local health food stores and pharmacies. Traditionally, activated charcoal is used to treat intestinal gas, cholestasis during pregnancy, and to lower cholesterol levels. So yes, even if you accidentally ingest this black substance, it is safe to use.

However, it can damage your teeth if used incorrectly. To work properly, it only needs to sit on the surface of your teeth for several minutes before being rinsed away.  Scrubbing it will scratch away the protective shell of enamel. Over time, this can cause your teeth to become grayish, sensitive, and susceptible to breaking.

Why You Should Visit Your Dentist First

No matter what product you’re planning on using, you should always see your dentist first. Your dentist can:

  • Help you pick the right product. Activated charcoal won’t work on deep stains or teeth that are yellowed from age. Your dentist can evaluate your personal situation and help you make the best choice for fixing the discoloration in your smile.
  • Ensure you’re healthy enough for teeth whitening. Hidden issues like thin enamel, tooth decay, or gum disease can cause discomfort during teeth whitening. Not only can your dentist spot these problems in advance, but they can also help you quickly and effectively treat them.
  • Give you professional results. If you’re nervous or unsure about using activated charcoal, a professional teeth whitening service from your dentist is a great alternative. These quick and affordable treatments are safe, comfortable, and can offer dazzling results in the same day.

I've been coming to this practice for years now since moving to the Raleigh area. The office is always clean and organized and the staff have always been friendly and communicative. Also, the TV's mounted to the ceiling are a nice touch! I've been seeing Dr. Laster for several years before our insurance changed causing me to change to Dr. Rensch. Both are so easy to talk to and always made me feel at ease.

From beginning to end 5/5! I thought I was experiencing a dental 911. I submitted an inquiry at 11:30pm and by 8am the next morning, Deidra (front office staff) was already leaving me a message. She was so sweet and patient at 8am lol. After our initial conversation, I informed all follow up dentists “I found my dentist office” but thank you so much! Today I was welcomed with the same energy from Diedre to Britany then finally Dr.Wrench. The music playing throughout the office was fantastic; ie music selection and volume. The TV’s on the ceiling and wall made my procedure so painless and enjoyable! I watched an entire Christmas movie lol! Dr. Wrench (apologies for spelling) made my teeth absolutely perfect! I left telling my friends and family I have a million dollar smile! 😊 I can tell he wanted them perfect and he did! Thank you all so much for being amazing! Sincerely, Your next patient.

Dr. Laster and Dr. Rensch go above and beyond for their patients. I have seen both for various treatments and I always feel comfortable and heard. They take time to listen and to talk with you. They explain your options and work with you to develop the best plan for your care. They are always upbeat and positive and you can tell they truly love what they do. The front desk staff is exceptional as well. Deidre is so caring and very sweet. She’s efficient, understanding and conscientious of your time. I highly recommend.

Connections Dentistry was great! The staff is so friendly and truly cares about their patients. My appointment was quick, and honestly the best dental experience I’ve had. They are great about offering helpful solutions without making you feel like you are being reprimanded… which was the reason I was putting off the dentist. 100% recommend!
