Ep. 6 | The Rising Threat of Colorectal Cancer and the Oral Microbiome Connection That Could Save Your Life
Colorectal cancer is the only cancer with rising mortality rates — and it's now the number one cancer killer for people under 50. Dr. Ellie Campbell and Dr. Kathleen Carson break down why it's happening, what warning signs to watch for, and the surprising role that mouth bacteria play in colon cancer development. Dr. Carson shares her own stage 3 colorectal cancer diagnosis at age 42 with no family history, and both doctors explain how diet, vitamin D, the oral microbiome, and early screening can save your life.

14. Ep. 14 | TMJ / TMD: The Real Drivers Behind Jaw Pain and Dysfunction
15:13||Season 1, Ep. 14You don't have "TMJ" — you have two of them, and everybody does. What you might have is TMD, and it's not one condition, it's dozens.In this episode, Dr. Ellie Campbell, DO and Dr. Kathleen Carson, DDS explore why jaw pain gets treated with a one-size-fits-all approach (stress! night guards! Botox!) when the real cause could be coming from your airway, your hormones, or a connective tissue condition you've never heard of. They break down how to figure out what's actually driving your symptoms.What you'll learn:Why "TMJ" just means the joint — and TMD is the actual disorder, with dozens of possible causesHow to spot the difference between a muscle problem and a joint problem in your own jawThe airway-jaw connection: why clenching and grinding can be a "check engine light" for sleep breathing issuesWhy women get TMD at much higher rates than men, and what hormones have to do with itHow PMOS (formerly PCOS) and hypermobility disorders like Ehlers-Danlos syndrome show up as jaw painWhy the wrong night guard or appliance can actually make your symptoms worsehttps://sleepsexandsenility.com#sleepsexandsenility #oralsystemichealth
13. Ep. 13 | Why Flossing Disappeared From Federal Health Guidelines
15:48||Season 1, Ep. 13Your dentist has told you to floss more your whole life — but the science behind that advice is shakier than you think, and in 2015 the government quietly agreed.In this episode, Dr. Ellie Campbell, DO and Dr. Kathleen Carson, DDS discuss why "just floss more" may be the wrong advice for most people, and what actually matters instead: reducing inflammation between your teeth. They break down what happened when journalists demanded evidence for flossing's inclusion in U.S. dietary guidelines, and why the real fix is often a different tool entirely.Topic highlights:Why flossing was removed from the federal dietary guidelines in 2015 — and what that does (and doesn't) meanThe real goal isn't flossing, it's reducing inflammation between your teethWhy "supervised flossing" works but flossing on your own often doesn'tWhen interdental brushes and water flossers outperform floss (tight vs. wide spaces, implants, gum recession, dry mouth)The mouth bacteria linked to Alzheimer's, and what actually reduces that riskWhy Teflon-coated "glide" floss may expose you to PFAS forever chemicalsLearn more: https://sleepsexandsenility.com
12. Ep. 12 | Preconception Health: How Sleep, Gum Disease & Hormones Affect Fertility
13:37||Season 1, Ep. 12Fertility doesn't begin with a positive test — it begins months, sometimes years earlier, in places nobody's looking. This episode reframes fertility as a whole-body health issue, not just a reproductive one.In this episode, Dr. Ellie Campbell, DO and Dr. Kathleen Carson, DDS discuss why inflammation — including inflammation in your mouth — plays a bigger role in fertility than most couples realize. They dig into the recent renaming of PCOS to PMOS (polyendocrine metabolic ovarian syndrome), why that name change matters, and why fertility planning needs to include both partners, not just the woman.You'll hear about:Why experts just renamed PCOS to PMOS, and what that reveals about the real root causesHow poor sleep worsens insulin resistance, which worsens hormone dysfunction, which affects ovulationWhy male fertility factors — including a 50% drop in global sperm counts over 40 years — are consistently left out of the conversationHow gum disease and oral inflammation connect to the same inflammatory pathways affecting fertilityWhat a comprehensive preconception health evaluation actually looks like for both partnersWhy vitamin D, magnesium, and progesterone levels matter as much as anything happening in the ovariesLearn more: https://sleepsexandsenility.comWatch on YouTube: https://youtu.be/fTicAMtqFMk
11. Ep. 11 | PCOS Is Now PMOS — And the Difference Could Save Your Life
25:58||Season 1, Ep. 11A medical diagnosis affecting millions of women just got a new name — and the change isn't just semantic. It could reshape how this condition is treated and how early the warning signs get caught.In this episode, Dr. Ellie Campbell, DO and Dr. Kathleen Carson, DDS discuss the landmark 2026 renaming of PCOS to PMOS — Polyendocrine Metabolic Ovarian Syndrome — and what this shift means for women, their doctors, and their dentists. Dr. Campbell shares the deeply personal story of her college friend Nancy, who died prematurely from liver failure caused by unmanaged PCOS complications. Dr. Carson explains how some of the earliest clues of this condition show up not in an endocrinologist's office, but in the mouth.In this episode, you'll hear about:Why the old name PCOS was misleading — and how many women with this condition don't even have ovarian cystsThe two-way connection between gum disease and insulin resistance, and why your dentist may catch it before your doctor doesHow sleep apnea and PMOS fuel each other in a vicious metabolic cycle — and how fixing your airway can help with weight loss without changing anything elseThe under-discussed liver disease risk in PMOS, and the story of one woman who paid the ultimate price for it going undetectedSimple strategies to reduce blood sugar spikes: the 10-minute post-meal walk, eating fiber first, and what your HbA1c is telling you before you're officially pre-diabeticWhat weight loss medications like tirzepatide (ZepBound) can — and can't — do for PMOS, and why oral health still needs to be part of the picturehttps://sleepsexandsenility.comWatch on YouTube: https://youtu.be/FcQgLYmGULs
10. Ep. 10 | Why You Can't Breathe Through Your Nose (And What to Actually Do About It)
20:49||Season 1, Ep. 10You've been told to breathe through your nose. But what if you genuinely can't? Drs. Campbell and Carson have an answer — and it's not "try harder."In this episode, Dr. Ellie Campbell, DO and Dr. Kathleen Carson, DDS discuss why so many people struggle with nasal breathing and why that struggle is a signal worth listening to, not a character flaw. They break down the three root causes of chronic mouth breathing (inflammation, structure, and function), explain the vicious cycle that makes congestion self-perpetuating, and share a practical roadmap for reclaiming your nose — at any age.Listeners will learn:Why chronic mouth breathing is almost always a compensation, not a bad habitHow congestion creates a feedback loop that makes nasal breathing progressively harder to restoreThe surprising mold connection behind recurring sinus infections — and what a Mayo Clinic study found inside patients' sinusesWhy the tissues inside your nose (turbinates) can actually decondition from years of disuse, just like musclesWhy mouth taping is later in the conversation, not the first step — and what needs to happen firstSimple starting points: saline rinses, allergy testing, sublingual immunotherapy, nasal strips, and breathing retraininghttps://sleepsexandsenility.comWatch on YouTube: https://youtu.be/viBFC6suyZc
9. Ep. 9 | Building a Healthier Baby Before Birth — Prenatal Nutrition, Oral Health, and the Microbiome Connection
27:15||Season 1, Ep. 9What you do before and during pregnancy can shape your baby's immune system, teeth, and health for the next 18 years.

8. Ep. 8 | Does Mouth Breathing Age You?
32:04||Season 1, Ep. 8Most people don't think twice about how they breathe — but mouth breathing may be silently accelerating your aging, disrupting your hormones, wrecking your microbiome, and even affecting fertility.

7. Ep. 7 | How Your Mouth Is Affecting Your Brain — Alzheimer's, Mercury, Sleep Apnea
35:27||Season 1, Ep. 7Could what's happening in your mouth right now be setting the stage for Alzheimer's disease? Dr. Ellie Campbell and Dr. Kathleen Carson explore five key ways your oral health directly impacts your brain: the mouth bacteria P. gingivalis and its link to Alzheimer's plaques, mercury in silver fillings as a neurotoxin, sleep apnea starving your brain of oxygen, the glymphatic system that cleans your brain at night, and the critical role of nitric oxide.
