What Is The White Discharge In My Mouth After Brushing?


“Dear DentaLux, Every time I brush, I notice a white, slimy discharge that covers my teeth and sometimes gobs up on my gums and the inside of my cheeks. What is this? What can I do to stop it?”

Like many people, this reader is troubled by a white, mucousy substance that can form on the teeth after brushing. A lot of people will ignore the cause of this problem and simply continue to rinse their mouth out with water, or even result to scraping the mucous off their teeth after each brushing. However, knowing about the cause behind this problem can help you get rid of that white, slimy discharge for good.

The mucous that you’re experiencing on your teeth, gums and inner cheeks is a direct result of the toothpaste that you are using. Some ingredients in toothpastes are too harsh for many mouths, and can actually burn the outer tissue of the oral cavity. This burned, dead tissue then forms into the globs and film of white discharge you find in your mouth anywhere from 10 minutes to an hour after brushing.

To stop this from happening, switch to a toothpaste that does not contain harsh whitening ingredients or peroxide. Silica-based whitening toothpaste should not cause this problem. It may also result from toothpastes with a high concentration of baking soda.

Your best bet is to switch to a toothpaste for people with sensitive teeth, at least for a little while. Mentadent and Sensodyne toothpastes are good recommendations for toothpastes that shouldn’t damage your mouth tissue. Toothpastes that have been known to cause the burning effect are Colgate and Crest Pro Health.

  1. Decided to give Crest Pro Health a try and NEVER AGAIN! Never had so many gobs of this slimy white film gather inside my mouth before… thanks for the post!!

      I have only noticed this after using Crest Pro Health and Listerine in tandem.

      • Laura says:

        I thought it was the Listerine that was doing this and then I brushed my teeth with Crest Pro Health alone and still had the same problem. That’s what sent me searching on Google and is how I found this page. Won’t ever be using that toothpaste again – how disgusting!

        • gwen says:

          I suffer from gum disease and i was advised to use corsodyl toothpaste and mouthwash by my dentist. This helped reduce the bleeding a little bit. Then i discovered Listerine for gums, it actually hepled me a lot within the first 2 weeks i saw a huge improvement compared to my 3months use of corsodyl. However, the listerine is so strong that it peels the skin on the inside of my cheeks and creates this sticky substance. it’s a win/lose situation because its doing great for my gum problem but the sticky aftermath is quite irritating.

    • KT says:

      I’m using Crest Complete that has Scope in it, along with Listerine. GOOD LORD. So much of that slime. It’s all on my gums, cheeks, and it gets on the back of my lips too. I had no idea what it was until just now. I really love Crest toothpaste though.

  2. Lee says:

    Can gum issues be caused by hormonal problems? I exercise great oral hygiene but started suffering from gum recession and swollen gums. The only thing besides hormones that I can think of is being too hard while brushing and flossing too deep.

    • Allison Arceneaux says:

      Your brushing technique may be incorrect. The proper way to brush is in a circular motion, following the gum line. You should use a soft bristle brush and hold it at a 45 degree angle. Do not brush hard, it can cause you to literally brush away your gums.
      As for the swollen gums, this may be a sign of gingivitis. Areas that are inflamed are in need of the most attention. Gingivitis can be reversed with proper brushing and flossing. Even if the gums bleed after flossing, don’t be alarmed are stop. Do it every day to get the bacteria out.
      Remember: brushing only cleans 65% of your teeth. Proper Flossing cleans the remaining 35%.
      Look up proper ways to floss.
      Hope this helped.

  3. Jane says:

    Do certain mouthwash(s) do this also? If so, are there any that don’t do this that also work well? Thanks for the info… so good to know, I had been wondering about this… Now I know to change my toothpaste… :) )

  4. KAY SCHROEDER says:

    Changed from AquaFresh to Sensodydne and it was the Sensodyne that caused mouth slime. Am going back to AquaFresh.

  5. Wow… I never knew that whitening toothpaste could irritate the inside of a mouth like that. Great unique information, thank you for the good read.

  6. glad says:

    Even the sensodyne is worse dan colgate because its doing same thing to me. I dnt know which paste to use again.

  7. AmiNa says:

    Thank u for your explanation I was worried, I really have a sentive teeth and sensodyne was prescribed for me, but I sometimes use the other paste. I also noticed that some sensodyne has the whitening ingredient u spoke about, I think that type should also be avoided.

  8. Levetrea Atkins says:

    I have been experiencing this mucous in my mouth after brushing and I decided to try biotene moisture rinse and to no avail I still have the problem. I do however use toothpaste with whitening ingredients and I will try the toothpaste for sensitive teeth.

  9. jamie says:

    I searched for this answer bc I had been getting a slimy glob of stuff in my mouth every time I brushed. Thank you for the article. I use crest prohealth. Never again… it is burning out the lining of my mouth. Crazy!

  10. Lisa says:

    I am so glad to know this informations because I get the same thing an I thought it was some form of bacteria!! I am going to switch to pronamal or sensodyne .

  11. Susan says:

    I really appreciate this post. I was really worried about this. Will switch right away! Many thanks! SZ

  12. Terry says:

    Thank you so much! I bought Crest Pro-Health for the first time a few weeks ago and have recently been experiencing this white mucous, and I didn’t connect the two.

  13. Tima Jiddou says:

    seeing that you recommended sensodyne was surprising for me since i had this problem for the first time because of it. At first i bought the whitening sensodyne thinking that it won’t be as harsh on my teeth as the other toothpastes out there but i kept having this weird white mucous like substance in my inner cheeks and on my gums it acctualy made me hate brushing my teeth as i was worried it’ll be on my teeth when i smile until i switched to another one and everything went back to normal so i really don’t recommened it and if you insist just try it you’ mouth might not react the same as mine

  14. Sydney says:

    I do use sensodyne and I still experience this white gunk that you described. Is there something else that could cause it?

    • dentaluxpa says:

      Hi Sydney!

      Another good option is Flouridex. It’s a gentle toothpaste (that also comes in a whitening variation) that is known to be more gentle on gums than other brands.

      Hope this helps!

  17. laron says:

    Wow I just tried the Crest Pro Health and within 15 minutes I had this! I was freaking out becauseI had it all over my gums! I will never use that junk again thats for sure!

  18. Jim says:

    There is an additive in some toothpastes “sodium laurel sulfate” which was used to clean garage floors, chemicals are harsh enough to chemical burn some of the skin inside your mouth when brushing teeth. Look at the ingredients listed if it has “SLS” or “sodium laurel sulfate” expect the white film / dead skin.

  19. Metrica says:

    I have had this a lot for the last year or so, it’s becoming impossible to find a good toothpaste that does not do this! But I am glad to see nothing terrifying is happening!

  20. Jess says:

    I’ve got it after switching to Oral B, from Colgate Whitening Toothpaste. The Oral B has grains in it, and now after brushing I get the strings. It’s disgusting. Also ‘dentist-recommended’. I’m never using it again.

  21. Tutorials says:

    Sensodyne is the cause in my case. Affeing my gums too, my gums are refraining from my teeth, so sensitive. Am quitting cold turkey right away. #bringbackmycloseup

  22. Curtis says:

    Awesome , didnt know this and i am using crest pro health but have other toothpaste i can use.
