Your toothpaste is rinsed away within minutes. Then comes the longest, quietest stretch of the day, with nothing left in place. OXY Shield is designed for that window.
Modern days are harder on teeth than the routine we were taught.
Oat lattes, sparkling water, a squeeze of lemon, a glass of wine. Each one is small. Together they add up to a day of repeated acid moments, and an evening routine that rinses its own protection down the sink.
i.
That sharp wince.
Cold water, ice cream, a breath of winter air. Sensitivity is the moment most people first notice something has changed.
ii.
The acid-forward diet.
Healthier habits are often more acidic ones. Fruit, kombucha, sparkling water and coffee all lower pH in the mouth.
iii.
Rinse, and it’s gone.
We brush for two minutes, then wash nearly everything away. The care ends the moment the tap runs.
iv.
The quiet night.
Saliva, the mouth’s natural buffer, slows to its lowest point while you sleep.1

02The gap
The routine covers minutes. The night lasts hours.
Set your own night. The overnight window is the single longest stretch your oral-care routine was never designed for.
120× longer than the time a rinse-off paste spends being brushed on each day.
Brushing time assumes the recommended two minutes, twice daily. The overnight window is simply the time between the last brush and waking.
03The format
Meet OXY Shield. Brush it on. Leave it on.
An anhydrous (waterless) mineral paste, made to be left in place after the final brush of the day. Same two minutes. Two small changes. A very different night.
In one line OXY Shield is a leave-on, waterless mineral paste you brush on with a dry brush at night and don’t rinse off, so it stays in place while you sleep.

No water. A small amount on a dry brush.
02

03
Spit. Don’t rinse.
Leave the film in place. Lights out.

04The category
Skincare learned to work overnight. Oral care never did.
Night serums and leave-in conditioners turned the hours of sleep into part of the routine. The mouth is the one daily ritual still built entirely around rinsing off.

Contact
Designed for duration, not foam.
Foam is a sensory cue, not a mechanism. OXY Shield is built to stay where it is put.
Timing
Made for the hours you’re not watching.
Applied last thing at night, when the mouth is quiet and nothing washes it away.
Guidance
Introduced by your dentist.
Dispensed chairside with a professional’s context. Never pushed from a supermarket shelf.
05Daily life
What changes is small. That is the point.
No new gadget. No extra step. The same two minutes before bed, just without the glass of water at the end.

45-night cycle

06The model
Not a shelf product. A clinic-led category.
OXY Shield reaches people through their dentist, then continues through a prescribed reorder cycle. The structure is designed so clinics are rewarded for care and follow-up, never for pushing volume.

07The people
Shaped in clinics. Trained in India and the UK.
Two clinician-operators building a more considered daily ritual and documenting the evidence as it develops.
OXY Shield is a leave-on, waterless (anhydrous) mineral paste from OXY Oral Sciences. You brush it on with a dry toothbrush as the last step of the night, spit out the excess and do not rinse, so a thin film stays in place through the overnight hours.
What is overnight oral care?
Overnight oral care is a routine designed for the hours you sleep, not just the two minutes you brush. Like a night serum in skincare, it uses a leave-on format applied before bed and left in place until morning.
How do you use OXY Shield?
Three steps, as the final step before bed: put a small amount on a dry toothbrush, brush gently for two minutes, then spit out the excess without rinsing.
Who makes OXY Shield?
OXY Oral Sciences Pvt Ltd, founded by Dr. Mahima Rama and Dr. Naveen John, dental clinicians trained in India and at the University of Glasgow.
Why leave something on overnight?
Saliva flow naturally slows during sleep, and most pastes are rinsed away within minutes of brushing. OXY Shield is designed for that window: applied last thing at night and left in place.
What does “waterless” mean?
The formula is anhydrous, meaning it is made without water. That is what allows a leave-on format with a dry brush and no rinse.
What does the evidence actually show?
Laboratory FE-SEM imaging of acid-etched human dentin specimens, tested in vitro at an accredited lab. It is mechanism-level evidence, not a clinical outcome, and we present it that way.
Can I buy it where I live?
Not yet. OXY Shield is launching in stages, beginning with clinics in India, and is not offered for sale elsewhere. Join the early-access list to hear about the science and any future availability.
Why is there no price on this page?
Because OXY Shield is dispensed through dentists rather than sold off a shelf. Patients receive it, and its terms, from their clinic. For clinics, we share the full structure at onboarding.
Why launch in India first?
Our model is clinic-led. Kochi and Bengaluru let us build it with clinics we know, under one regulatory pathway, before anywhere else.
Does this replace my dentist?
No. OXY is built to work alongside professional care, not around it. If you have pain or sensitivity, see a dentist.
