[@thirtyacres7504]

Some people grind their teeth when they're sleeping, or even when they're not sleeping, including clenching. All of these can lead to gum recession. Unfortunately, bruxism while sleeping can only be countered by wearing a mouthguard.

Thank you for sharing, J 🙂🙏 Miss you too. 😊 Seunghee is such a professional at explaining. 👏 J, you're like a proud boss/brother/friend 😆 For the gum recession, would you brush any differently? Could you share more about the specialized care and techniques? If you have any tips for people in my situation, that'd be awesome 🙂🌻 I also had an Oral-B electric toothbrush 2000 that was gifted to me a while back. I noticed slight canine gum recession then. I started to clench my teeth at night ever since my car accident in 2021. I have Invisalign retainers and my dentist suggested getting an NTI. There were times that I sensed the pressure of my clenching after removing my NTI with retainer in the morning. This also doesnt help that I have TMD/TMJ. I wear the NTI on and off just to check when I clench at night. I know I don't clench every night. Clenching might have increased my gum recession and noticed recession along molar areas as well with some bad habits you've mentioned in your videos. I'm doing better with my car accident injuries now just the jaw clenching remains. My dentists said I dont need surgery for TMD/J so I've been trying chiropractic adjustments, massage and acupuncture to relieve jaw pain. I am testing to see which traditional/modern approach works and what I could learn from each practitioner. I backed off from electric toothbrush out of fear that I'm making it worse🥲 Finding a soft toothbrush is like finding a life partner amidst a market of hard/medium toothbrushes.

Thank you for the video Dr. John, super informative! One follow up question - what is the correct way if we are not supposed to rinse with water after brushing? I feel like I need the water to get rid of the uncomfortable tiny debris in my mouth after brushing. Or should I be using mouthwash to rinse? Or not rinse at all and just spit?

[@dr.johnyoo]

yes, spit excess including residue. if uncomfortable with feeling, rinsing with a xylitol or fluoride mouthrinse helps. another option, which is more cumbersome but achieves same goal, is to brush, rinse, and then brush with a small amt of toothpaste again

Hey,Doc! Thank you so much for these educational videos. Not all of us were brought up with any of this, and it has helped me improve my dental health. I have shared these with my friends and they learned a lot too. A future suggestion topic for me would be the flossing. I have tried several kinds of products and I don’t like how it seems to shred or stick between some of my teeth. I understand the importance for sure. I definitely do after eating foods like celery 🦷😁

[@dr.johnyoo]

if floss is shredding , try one that's a bit thinner/waxed in texture , such as oral B's glide floss. i personally prefer the thicker ones with more texture (coco floss) to dislodge more effectively . but give those 2 a try and lmk !

People are getting mad about Dr. John not rinsing after brushing, but when I asked Kriss ai if that's okay, it turns out it's actually recommended by dentists so that the fluoride has more time to work and protect your teeth!

I don't think I'm comfortable with the idea of walking around with a strong taste of toothpaste in my mouth 😩 from where exactly did you confirm Dr. John's tip?

Can u do a video on growing back gum gum recession? Is it even possible?

[@qianjin88]

had to rewatch for educational purposes…. 1. what is canine recession and how do i know if i have it or not 2. how often should we change out our non-eco friendly plastic tongue scrapers; how to maintain a stainless steel one 3. laifen sounds a bit chinese… any plans to rebrand to something more korean? 😂😂😂i know it’s still early in the morning but my adhd brain just wants to know thaaaaangs lol

[@dr.johnyoo]

1. canine recession is the photo on the thumbnail. my canines looks like that lol.. normally if you see darker shade of tooth below the crown, that's the root being exposed (receding gums). easiest way to confirm is to ask your dentist if you have any signs of recession. sometimes they're localized (specific teeth, sometimes more generalized - throughout). more people get them on their canines 2. stainless steel lasts longer. i swap my plastic tongue scraper every time i swap brush head 3. ur right ! Laifen is a trusted Chinese tech/health devices company. i cant rebrand it , it's not mine lol 😂

Thanks Doc, Can gum recession be reversed at home with any lifestyle approach?

[@Star-Bright]

You have to change your diet to have low carb & no processed foods. That way your saliva is a mineralizing pH. It’s the food you eat that feed the cavity causing bacteria. Next is blood flow to your teeth by massaging your gums gently. Green juicing, minerals, Oil pulling & xylitol will help.

[@Ploy.Matthiya]

My problem is I don’t trust any dentists here easily so when I need to do the bite-wing I just need uncle to do it, which is so far away. Except this I m ok, family concerns about the teeth since I was young so it turn out good. To watch urs and listen to my uncle helps a lot, both r the best dentists in my mind 🎉😊🎀

[@andremulia92]

Thanks for the video, it really helps. Is there a way to treat gum recession? Or what would happen to the teeth?

[@dr.johnyoo]

yes there are ways to treat recession, including gum grafting and pinhole surgery. teeth associated with gum recession may become more sensitive due to root exposure and gaps/pockets may form between teeth. elongated teeth (due to exposure of root) are considered less esthetic due to its increased prevalence with aging

[@nirsommer]

I make sure my toothbrush is clean and then shake it to partially dry it. Then I put my toothbrush in a ventilated travel case and put it next to my bedrooms window to air dry. This way it doesn't get contaminated from toilet usage.

[@DimitriLyon]

If we are not supposed to rinse right after brushing, how long do you recommend we delay rinsing? Also, do I follow up with a mouthwash after, or before brushing? Since some mouthwashes contain fluoride is it okay to rinse with water and then do the mouthwash to maintain the benefits of the fluoride? I find it hard to not rinse after brushing. The taste of the toothpaste just sitting there just feels unnatural.

[@wolfferoni]

If you're using a mouthwash with fluoride after brushing then yes, it's fine to rinse with water after brushing. Don't rinse after you use mouthwash though. I found it difficult to avoid rinsing after brushing too, felt a bit gross to me, but you get used to it over time. You could change the flavour of your toothpaste if you don't like the taste

[@lizb8843]

Hi👋🏽 it’s my first time on the channel. Great video! I have questions 🤷🏽‍♀️ Sooo, I already have some gum recession. I use the Nimbus extra soft toothbrush and you’re saying I shouldn’t use an electric incl. the one you mention? I don’t scrap my tongue because I have Sjogrens and my mouth is really dry, I use my brush and scrap forward, is that enough? We should brush at a 45 degree angle in a circular motion and not touch the gums??? A really detailed demonstration would be soooo awesome! And can I just say, do other people not close the toilet lid? What? I grew up doing that and not doing it is just gross😮. What did you think the lid was for if you’re out closing it? Do you know how far those particles travel if you flush without shutting the lid? Srsly 6 feet. Ok TMI…

[@LyssieLysse]

I didn’t even know half of these things, especially about the using electric toothbrushes on receding gums. All of the dentists I’ve had always told me to use the Sonicare toothbrush, but it was too abrasive and now I have a few places where my gums are receding. I switched to Oral-B and use an extra soft toothbrush head, but I might go back to manual brushing. I never had an issue with it. I just have an issue with dental hygienists not wanting to clean my teeth properly.

[@wryed]

what are your thoughts on interdental brushes instead of flossing? if I don't rinse my mouth right after brushing do I just spit out all the tooth paste and eventually swallow what I couldn't fully spit out? I rinse after brushing because I'm uncomfortable with the toothpaste still in my mouth 😭

[@dr.johnyoo]

interdental brushes are efficient in cleaning larger spaces, braces, and bridges, however the dental floss "breaks" through contacts between teeth and can effectively clean between tight spaces. both have their use cases. dont replace your flossing with interdental though, use as adjunct and yes spit excess. if uncomfortable with residue feeling, rinsing with a xylitol or fluoride mouthrinse helps

[@dr.johnyoo]

the idea behind that is that you need a certain level of vit C to maintain healthy gingiva (gums). vitamin C deficiency can lead to gum problems . so it's not the apple uniquely , but rather the vitamins in it . if that's what youre wondering !

@@dr.johnyoo thanks for the answer!

[@iu2]

2:50 "Brushing right after eating...wait 30 minutes" Why wait? I understand that pH levels may be too low after eating, but why not just rinse your mouth with water? This is basic chemistry: a cup full of water will IMMEDIATELY raise the pH in your mouth to at least 6.5. There's no reason to wait if you rinse your mouth. Also, once the toothpaste hits your teeth, the pH will also immediateley rise.

[@whoisalken]

I think that's exactly it. I'm not sure but maybe it is to raise the pH level, SLOWLY. if you rinse it with water it just instantaneously raises your mouth's pH level. im not sure tho.

[@dr.johnyoo]

great point!! love that you brought this up you're absolutely right in that the oral cavity pH will quickly restore with water/alkaline rinse, and is an effective hygiene habit. the reasons we wait, even after swishing, is that 1. the ENAMEL itself is still compromised temporarily and 2. certain microbia present in plaque can quickly produce acids after carbohyrate feeding. more details below: reason #1, the enamel becomes porous or "etched" with each acid exposure, depending on contact time and pH (i.e. sipping on lemon juice does more damage to enamel than drinking coffee) . habitually brushing the compromised enamel surface immediately after, even if the rest of the mouth has normal pH, abrades the enamel's surface. reason #2, certain carbs/sugars enable plaque bacteria to produce acids on enamel during and after feeding the guideline of waiting 30 min is a parameter to allow safer condition of enamel to be brushed, though there are ways to speed up the pH restoration in the meantime, as you mentioned. if it seems unrealistic to wait that long to brush however, as mentioned in the pro tip, we still do advise brushing. hope this clarifies, and thanks for bringing it up!
