3 Conditions for No-Prep Veneers — Shown Through Real Cases
Hello. I'm Park Jonguk, head of Dream Dental Clinic in Apgujeong.
Today I'm talking about no-prep veneers.
"Can I get veneers without having my teeth ground down?"
Yes, you can — as long as the conditions are right.
What are no-prep veneers?
Exactly what the name says: veneers done without reducing the tooth at all.
A thin piece of ceramic is bonded onto the front surface of the tooth.
There's no damage to the tooth structure.
The natural tooth is 100% preserved.
But it's not for everyone
No-prep veneers come with conditions.
They're not possible for everyone.
Three conditions have to be met.
The 3 conditions for no-prep veneers
Condition 1: The teeth must be small
This means peg-shaped or otherwise small teeth.
Bonding ceramic onto the front of a tooth makes it larger.
If the tooth was originally small, it becomes a normal size.
But what if the tooth is already large?
It gets even bigger and becomes an oversized tooth.
That looks awkward and unnatural.
Condition 2: The alignment must be even
The teeth can't be crooked.
No-prep veneers can't significantly change a tooth's position.
If the alignment is already even, the veneer just needs to sit on top of it.
What if the alignment isn't even?
Then orthodontics is needed first, or some reduction is required.
Condition 3: The teeth must not protrude
The teeth can't stick out forward.
If ceramic is bonded on the front with no reduction?
It sticks out even more.
The mouth ends up looking like it protrudes.
A slightly retruded tooth is actually a better fit.
Summing up the three conditions
Condition 1: The teeth must be small
Condition 2: The alignment must be even
Condition 3: The teeth must not protrude
All three have to be met for no-prep veneers to be possible.
Real case 1
Before treatment
This fits the conditions perfectly.
The teeth are small.
The alignment is even.
They don't protrude.
This is a perfect candidate for no-prep veneers.
After treatment
Natural and beautiful.
The tooth size has become appropriate.
The shape is harmonious.
They look bright and healthy.
The teeth weren't reduced at all.
Real case 2
Before treatment
This patient also meets all three conditions.
The teeth are small.
The alignment is even.
They don't protrude.
After treatment
Natural and beautiful.
The once-small teeth are now a normal size.
The color has brightened as well.
The shape has become more attractive too.
This too was completed without any tooth reduction.
Real case 3
Before treatment
This also fits the conditions perfectly.
The tooth size is small.
The arrangement is even.
They don't stick out forward.
After treatment
Natural and beautiful.
A radiant, bright smile.
Each individual tooth is in harmony.
The translucency looks just as alive as a natural tooth.
All of this was achieved with no tooth reduction.
Advantages of no-prep veneers
100% preservation of the tooth
This is the biggest advantage.
The healthy tooth isn't damaged at all.
It stays a natural tooth for life.
No pain
Since the tooth isn't reduced, anesthesia isn't even needed.
There's no pain at all.
It's a comfortable treatment.
Reversible treatment
It can be removed later if needed.
You can return to your original tooth.
It's not an irreversible treatment.
Fast treatment
Since there's no tooth-reduction step, it's faster.
The number of clinic visits is reduced too.
What if the conditions aren't met?
Minimal-reduction veneers
What if even one of the three conditions isn't met?
No-prep becomes difficult.
But it can still be done with minimal reduction (0.3-0.5mm).
Only a very small amount of the tooth is reduced.
It's still a minimally invasive treatment.
A precision diagnosis is needed
Whether no-prep is possible or not —
this can only be determined through a precision diagnosis.
It's checked in advance with a wax-up diagnosis.
Forcing no-prep when it isn't suitable results in oversized teeth.
An accurate judgment matters.
Are you a candidate for no-prep?
Self-check
Are your teeth small? Check ✓ if they're peg-shaped or smaller than average
Is your alignment even? Check ✓ if they're not crooked and sit in a neat row
Do they not protrude? Check ✓ if they don't stick out forward
Did you check all three?
You're highly likely to be a candidate for no-prep veneers!
An accurate judgment comes from diagnosis
The self-check is for reference only.
An accurate judgment requires a precision diagnosis.
The result is previewed in advance with a wax-up.
This tells you for certain whether no-prep is possible.

Frequently Asked Questions (Q&A)
Q1. Can anyone get no-prep veneers?
A. No, three conditions have to be met. First, the teeth must be small; second, the alignment must be even; third, the teeth must not protrude. If even one of these isn't met, no-prep becomes difficult, and I recommend minimal-reduction (0.3-0.5mm) veneers instead. An accurate judgment can be made through a wax-up diagnosis.
Q2. Do no-prep veneers look natural too?
A. Yes, for a case that fits the conditions, they look very natural. When someone with small teeth gets no-prep veneers, the teeth become a normal size, which actually ends up looking even more natural. The key is precisely reproducing the translucency and color using the buildup method. Dream Dental Clinic in Apgujeong has done a great deal of natural-looking no-prep veneer treatment over 20 years.
Q3. Since it's no-prep, won't it come off later?
A. There's no need to worry. Modern adhesive technology has advanced a great deal. Bonding directly to enamel actually gives better adhesion. When a tooth is reduced, the enamel is lost and the bond has to be made to dentin instead, which can reduce adhesion. Since no-prep preserves 100% of the enamel, it's actually advantageous in terms of bond strength.
