I’m a periodontist and academician with a strong clinical and teaching background. Over the last 4 years and 8 months, I’ve been actively involved in dental education, guiding students at multiple levels including dental hygienist, BDS, and MDS programs. Currently, I serve as a Reader at MMCDSR in Ambala, Haryana—a role that allows me to merge my academic passion with hands-on experience. Clinically, I’ve been practicing dentistry for the past 12 years. From routine procedures like scaling and root planing to more advanced cases involving grafts, biopsies, and implant surgeries. Honestly, I still find joy in doing a simple RCT when it’s needed. It’s not just about the procedure but making sure the patient feels comfortable and safe. Academically, I have 26 research publications to my credit. I’m on the editorial boards of the Archives of Dental Research and Journal of Dental Research and Oral Health, and I’ve spent a lot of time reviewing manuscripts—from case reports to meta-analyses and even book reviews. I was honored to receive the “Best Editor” award by Innovative Publications, and Athena Publications recognized me as an “excellent reviewer,” which honestly came as a bit of a surprise! In 2025, I had the opportunity to present a guest lecture in Italy on traumatic oral lesions. Sharing my work and learning from peers globally has been incredibly fulfilling. Outside academics and clinics, I’ve also worked in the pharmaceutical sector as a Drug Safety Associate for about 3 years, focusing on pharmacovigilance. That role really sharpened my attention to detail and deepened my understanding of drug interactions and adverse effects. My goal is to keep learning, and give every patient and student my absolute best.

Hello dear
See sensodyne has been successfully tested in human trial and no side-effects have been reported
Probably it is an allergic reaction to one of the components probably desensitised agent.
I suggest you to please stop and replace sensodyne with
Colagate or pepsodent
Do regular mouthrinsing with water
Take zincovit multivitamin therapy for b2 deficiency and lip irritation
Please follow fir atleast a week
In case of no improvement consult nearby dentist for better clarity

I am a general dentist with 3+ years of working in real-world setups, and lemme say—every single patient teaches me something diff. It’s not just teeth honestly, it’s people… and how they feel walking into the chair. I try really hard to not make it just a “procedure thing.” I explain stuff in plain words—no confusing dental jargon, just straight talk—coz I feel like when ppl *get* what's going on, they feel safer n that makes all the difference. Worked with all ages—like, little kids who need that gentle nudge about brushing, to older folks who come in with long histories and sometimes just need someone to really sit n listen. It’s weirdly rewarding to see someone walk out lighter, not just 'coz their toothache's gone but coz they felt seen during the whole thing. A lot of ppl come in scared or just unsure, and I honestly take that seriously. I keep the vibe calm. Try to read their mood, don’t rush. I always tell myself—every smile’s got a story, even the broken ones. My thing is: comfort first, then precision. I want the outcome to last, not just look good for a week. Not tryna claim perfection or magic solutions—just consistent, clear, hands-on care where patients feel heard. I think dentistry should *fit* the person, not push them into a box. That's kinda been my philosophy from day one. And yeah, maybe sometimes I overexplain or spend a bit too long checking alignment again but hey, if it means someone eats pain-free or finally smiles wide in pics again? Worth it. Every time.

Hello
Your symptoms are most likely due to chronic irritation of the lip border (irritant contact dermatitis) that began after using Sensodyne. Some people develop sensitivity to certain toothpaste ingredients, especially foaming agents or flavoring chemicals. Repeatedly cleaning or rubbing the white area when it gets wet can also thin the skin over time and cause the mild burning sensation you described. This condition is usually not dangerous and does not mean permanent damage, but it can persist if the irritation continues.
What you should do now is switch to a very gentle, non-foaming toothpaste and avoid rubbing or scrubbing the lip border frequently. Apply a simple protective layer like petroleum jelly to the area two to three times daily to help the skin heal. Try to gently pat the area dry after bathing or brushing instead of wiping repeatedly. If the burning continues, a doctor may prescribe a short course of a mild antifungal or anti-inflammatory cream to calm the irritation.
If the skin keeps thinning, develops cracks, bleeding, spreading redness, or does not improve after about two to three weeks of gentle care, you should see a doctor or dentist for an in-person examination.
Take care

I am a 2023 batch passout and working as a general physician right now, based in Hanumangarh, Rajasthan. Still kinda new in the bigger picture maybe, but honestly—every single day in this line teaches you more than textbooks ever could. I’ve had the chance to work under some pretty respected doctors during and after my graduation, not just for the clinical part but also to see how they handle people, real people, in pain, in panic, and sometimes just confused about their own health. General medicine covers a lot, right? Like from the smallest complaints to those random, vague symptoms that no one really understands at first—those are kinda my zone now. I don’t really rush to label things, I try to spend time actually listening. Feels weird to say it but ya, I do take that part seriously. Some patients just need someone to hear the whole story instead of jumping to prescription pads after 30 seconds. Right now, my practice includes everything from managing common infections, blood pressure issues, sugar problems to more layered cases where symptoms overlap and you gotta just... piece things together. It's not glamorous all the time, but it's real. I’ve handled a bunch of seasonal disease waves too, like dengue surges and viral fevers that hit rural belts hard—Hanumangarh doesn’t get much spotlight but there’s plenty happening out here. Also, I do rely on basics—thorough history, solid clinical exam and yeah when needed, investigations. But not over-prescribing things just cz they’re there. One thing I picked up from the senior consultants I worked with—they used to say “don’t chase labs, chase the patient’s story”... stuck with me till now. Anyway, still learning every single day tbh. But I like that. Keeps me grounded and kind of obsessed with trying to get better.

Hello
It sounds like your lip border has been affected by prolonged dryness and irritation, leading to changes in its appearance. Here’s how you can help it heal and return to a more normal state:
### Steps to Heal Your Lip Border
1. Gentle Cleansing:
- Use a mild, fragrance-free cleanser to wash your face and lip area. Avoid scrubbing or using harsh soaps that can further irritate the skin.
2. Moisturize Regularly:
- Apply a thick, emollient lip balm or ointment (like petroleum jelly) to the lip border several times a day, especially after washing your face or eating. This will help lock in moisture and protect the skin.
3. Avoid Irritants:
- Stay away from flavored or medicated lip products, as they can cause further irritation. Also, avoid spicy or acidic foods that might aggravate the area.
4. Hydration:
- Drink plenty of water throughout the day to keep your body and skin hydrated. This can help improve the overall condition of your skin.
5. Sun Protection:
- If you’re going outside, use a lip balm with SPF to protect your lips from sun damage, which can worsen dryness and irritation.
6. Limit Cleaning:
- Instead of cleaning the area aggressively, gently pat it dry after washing. Over-cleaning can strip the skin of its natural oils and worsen dryness.
7. Consider a Humidifier:
- If you’re in a dry environment, using a humidifier can help add moisture to the air, which can benefit your skin and lips.
### When to See a Doctor
- If the area doesn’t improve in a few weeks, or if you notice any new symptoms (like increased pain, swelling, or bleeding), it’s a good idea to consult a dermatologist. They can assess the condition and may prescribe a topical treatment to help with healing.
### Patience is Key
Healing can take time, especially if the skin has been irritated for a while. Be gentle with the area and give it time to recover. With consistent care, you should start to see improvement!
Thank you

I completed my medical degree in 2023, but honestly, my journey in healthcare started way before that. Since 2018, I’ve been actively involved in clinical practice—getting hands-on exposure across multiple departments like ENT, pediatrics, dermatology, ophthalmology, medicine, and emergency care. One of the most intense and defining phases of my training was working at a District Government Hospital for a full year during the COVID pandemic. It was chaotic, unpredictable, and exhausting—but it also grounded me in real-world medicine like no textbook ever could. Over time, I’ve worked in both OPD and IPD setups, handling everything from mild viral fevers to more stubborn, long-term conditions. These day-to-day experiences really built my base and taught me how to stay calm when things get hectic—and how to adjust fast when plans don’t go as expected. What I’ve learned most is that care isn't only about writing the right medicine. It’s about being fully there, listening properly, and making sure the person feels seen—not just treated. Alongside clinical work, I’ve also been exposed to preventive health, health education, and community outreach. These areas really matter to me because I believe real impact begins outside the hospital, with awareness and early intervention. My approach is always centered around clarity, empathy, and clinical logic—I like to make sure every patient knows exactly what’s going on and why we’re doing what we’re doing. I’ve always felt a pull towards general medicine and internal care, and honestly, I’m still learning every single day—each patient brings a new lesson. Medicine never really sits still, it keeps shifting, and I try to shift with it. Not just in terms of what I know, but also in how I listen and respond. For me, it’s always been about giving real care. Genuine, respectful, and the kind that actually helps a person heal—inside and out.

I am currently working as a urologist and kidney transplant surgeon at Graphic Era Medical College & Hospital, Dehradun. It's a role that keeps me on my toes, honestly. I handle a pretty wide range of urology cases—stones, prostate issues, urinary tract obstructions, infections, you name it. Some are straightforward, others way more complex than you expect at first glance. Every patient walks in with a different story and that’s what keeps the work real for me. Kidney transplant surgery, though, that’s a whole different zone. You’re not just working on anatomy—you’re dealing with timelines, matching, medications, family dynamics, emotional pressure... and yeah, very precise coordination. I’m part of a team that manages the entire transplant process—from evaluation to surgery to post-op care. Not gonna lie, it’s intense. But seeing someone who’s been on dialysis for years finally get a new shot at life—there’s nothing really like that feeling. In the OR, I’m detail-focused. Outside of it, I try to stay accessible—patients don’t always need answers right away, sometimes they just need to feel heard. I believe in walking them through what’s going on rather than just giving reports and instructions. Especially in transplant cases, trust matters. And clear, honest conversation helps build that. Urology itself is such a misunderstood field sometimes. People ignore symptoms for years because it feels “awkward” or they think it’s not serious until it becomes unmanageable. I’ve had patients who came in late just because they were embarassed to talk about urine flow or testicular pain. That’s why I also try to make the space judgment-free—like whatever it is, we’ll figure it out. At the end of the day, whether I’m scrubbing in for surgery or doing OPD rounds, I just want to make sure what I do *actually* helps. That the effort’s not wasted. And yeah, some days are frustrating—some procedures don’t go clean, some recoveries take longer than they should—but I keep showing up, cause the work’s worth doing. Always is.

Hi there 👋
This is Dr. Nikhil Chauhan. I understand your concern – a thinning, burning lip border is frustrating. Let me explain what’s likely happening.
🔍 What’s causing this?
1. Allergic contact dermatitis to Sensodyne
· Common culprits: stannous fluoride, sodium fluoride, or cocamidopropyl betaine (a foaming agent).
· Burning, peeling, white film when wet → classic signs of irritation.
2. Repeated mechanical trauma
· You’ve been cleaning that white residue daily for a year – that’s scrubbing away your delicate lip border skin.
· Result: thinning, flattening, and “moving backward” (scar-like retraction).
3. Loss of natural barrier
· Damaged vermilion border → moisture escapes → more white maceration when wet → more cleaning → vicious cycle.
✅ What to do right now:
· Stop Sensodyne completely – never use it again.
· Use a hypoallergenic, fluoride-free toothpaste (e.g., Squigle, Orawellness, or simple baking soda + water).
· Stop scrubbing/cleaning the white residue – let it be. Gently pat dry, don’t rub.
· Apply a thick barrier – petroleum jelly (Vaseline) or lanolin (if no wool allergy) 3-4x daily and before bed.
· Avoid licking lips, spicy foods, and mint-flavored products.
📅 When to see a doctor:
If no improvement in 2-3 weeks → see a dermatologist. They may prescribe a mild steroid ointment (hydrocortisone) to calm inflammation.
💡 Good news:
This is not dangerous and usually reversible if you stop the irritant and protect the skin. Your lip border can slowly regenerate.
Stop scrubbing, switch toothpaste, and be patient. You’ll heal. 🌟
– Dr. Nikhil Chauhan
