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.

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,

Being in a closed garage while a car is running can be dangerous because of carbon monoxide (CO), but in your specific situation the risk is 🛑very low.

You were exposed for about 30 seconds, which is a very short time.

The engine was not left running for minutes, and afterward you stayed in the garage for about 5 minutes with the car off.

Carbon monoxide poisoning typically requires longer exposure or higher concentrations, especially in a tightly sealed space with the engine running continuously.

The most reassuring point is that it’s been about an hour and you feel normal.

Symptoms of meaningful CO exposure—such as headache, dizziness, nausea, confusion, chest discomfort, or shortness of breath—usually appear during or shortly after exposure. If none of these have occurred, significant poisoning is extremely unlikely.

At your age (18) and assuming you’re otherwise healthy, your body would not be expected to have any delayed effects from such a brief exposure.

Carbon monoxide does not stay in the body once exposure stops and fresh air is breathed.

This brief, accidental exposure is very unlikely to have caused any harm. No action is needed unless you develop symptoms later, in which case you should seek medical care. Avoid running cars in closed garages in the future, even briefly, to stay safe.

I trust Its clear and helpful Thank you
