Where to Put Teeth Whitening Strips (So They Actually Work)
Written by Sheikh Ismail Zabi, Founder and CEO of PureSmile, Dubai's halal-certified, cruelty-free, PAP+ teeth whitening brand.
When people buy teeth whitening strips, they usually get two things in the box: a dream of whiter teeth, and a tiny instruction card nobody really reads.
And the main confusion is always the same:
- Do I put them on all my teeth?
- Do they go on the gums?
- Front only or also back?
- Top only or bottom too?
Let me clear this up once and for all with real, practical guidance.
Short Answer: Where Do You Put Teeth Whitening Strips?
You put teeth whitening strips on the front (outer) surface of your upper and lower front teeth, aligned with the gum line, touching your teeth only, not your gums.
Target area: The part of your teeth that shows when you smile.
Avoid area: Gums and soft tissue.
You are targeting the aesthetic zone, the teeth people actually see when you smile. No need to wrap them around every tooth in your mouth.
Step-by-Step: How to Place Whitening Strips Correctly
Step 1: Start With Clean, Dry Teeth
- Brush your teeth gently, preferably 30 minutes before applying, not immediately before, to avoid extra sensitivity
- Dry the front of your teeth with a tissue before applying
Strips stick better to dry enamel. If your teeth are too wet, the strip can slide or lift, which means uneven whitening.
Step 2: Upper Strip - Place on the Front Surface of Your Top Teeth
- Hold the strip in front of a mirror
- Line the straight edge of the strip with your gum line, but do not let it sit on the gums
- Press the strip onto the front of your upper teeth, the part facing your lips
- Smooth it down with your finger to remove air bubbles
- If there is extra length, fold the remaining strip behind your teeth, but only if it feels comfortable and does not cut into your gums
The goal is full contact with the front surface of the teeth you show when you smile, usually from canine to canine or premolar.
Step 3: Lower Strip - Repeat for the Bottom Teeth
- Align with the gum line on the lower front teeth
- Press gently and smooth it across
- Fold any extra behind the teeth if the strip is long enough and it feels comfortable
Most people only need to cover the front 6 to 8 lower teeth because that is what shows when you talk or smile.
Step 4: Where Not to Put the Strips
- Not on your gums, this can cause irritation and discomfort
- Not on broken, decayed, or heavily chipped teeth without a dentist's advice
- Not on fillings, crowns, or veneers expecting them to whiten, they will not change shade like natural enamel
- Not on the backside of your teeth unless the product specifically says so
Whitening strips are designed for front, visible enamel, not as a full-mouth wrap.
Where to Put Them in Your Daily Routine (Timing Matters Too)
Where is not just about location on your teeth. It is also about where in your day you place the habit. Most people get the best results when they use strips once a day, consistently, at a time when they will not be eating, drinking, or talking too much. Good options are in the evening after dinner or at night before bed.
For PureSmile PAP+ Whitening Strips, apply once a day, leave on for the recommended 30 minutes, and avoid eating or drinking during that period.
How Your Placement Affects Your Results
From my experience building PureSmile and from what UAE dentists have shared with me:
- People who place strips too low or too high, partly on gums, often experience mild burning, redness along the gum line, and want to remove the strip early
- People who place strips only on the middle four teeth and ignore the sides often end up with whiter front teeth but slightly darker canines, creating an uneven smile
The fix is simple: align with the gum line but do not cover it, and cover all visible teeth when you smile, not just the two in the center. That is where good whitening turns into good-looking whitening.
Common Placement Mistakes and How to Fix Them
Mistake 1: Strips accidentally placed on the gums
If the strip touches your gums a little it is not the end of the world, but if it sits on your gums you may feel irritation or burning. Fix: gently peel back the strip and reposition it so it only touches enamel.
Mistake 2: Strips keep sliding or lifting at the edges
This usually means teeth were not dry enough when you applied, or you are talking or moving your lips too much. Fix: dry your teeth properly before application, press firmly with a finger after placing, and smooth along each tooth especially at the corners.
Mistake 3: Only the front two teeth are white
This is a placement and coverage issue. If you only placed the strip over the very center, the edges of your smile stay darker. Fix: make sure the strip covers all the teeth you show when you smile, not just the middle. If your strip is wide enough, gently stretch and smooth it sideways.
Why Placement Matters More With Safe Formulas
With harsh whitening systems, you can sometimes apply them carelessly and still see dramatic but risky results. With safer, enamel-friendly formulas like PAP+, which is what we use in PureSmile, you are playing a long, smart game: no burning, no sensitivity, gradual and comfortable whitening.
But for that to work, contact needs to be consistent: full contact with the enamel, even distribution across the visible teeth, and proper time on teeth as recommended. So where you put the strips is what turns a safe formula into visible, even results.
Frequently Asked Questions
Do I put strips on both top and bottom teeth?
Yes, if your kit includes both. Most whitening systems come with one strip for the upper teeth and one for the lower teeth. Use both in each session unless your instructions say differently.
Should I put them on the inside (tongue side) of my teeth?
No. You do not need to whiten the back surface of your teeth. It does not affect how your smile looks. Focus on the front, outward-facing side of your teeth.
How close to the gums should I place them?
As close as you can without touching the gums. Think borderline, not overlapping.
Can I cut the strips and only use them on a few teeth?
You can, but you risk uneven whitening if you only do a few teeth long-term. For most people, applying to all visible teeth is best.
Where should I store the strips between uses?
Keep them in a cool, dry place away from direct heat and sunlight. A closed drawer or bathroom cabinet away from steam is fine. Do not leave them in a hot car or near a window.
Are PureSmile strips halal and safe for UAE and GCC consumers?
Yes. PureSmile PAP+ Whitening Strips are independently halal-certified, peroxide-free, alcohol-free, and vegan. They are trusted by customers and dental professionals across the UAE, Saudi Arabia, Kuwait, Qatar, and the wider GCC.
Final Word: Put Them Where the Smile Lives
If you remember nothing else from this article, remember this: put whitening strips on the teeth people see when you smile, close to the gum line, but never on the gums.
That is the difference between strips that feel weird and do nothing, and strips that give you even, comfortable results with enamel that still loves you afterward.
Now you know exactly where to put whitening strips for the best results. The next step is choosing strips that are actually worth placing correctly.
