Hello.
This is Blanche Dental Clinic, where your smile becomes a work of art.
Recently, “no-prep laminate veneers,” which do not require shaving down the teeth, have become very popular.
It makes sense that patients want to preserve their natural teeth.
However, experts say that instead of insisting on no-prep in every case, there is a different method that is “right for me.”
Today, we will explain the crucial differences between no-prep and minimal-prep treatment, and the standards for a procedure that avoids failure.
One of the most common requests during dental consultations is, “Please do not shave them down at all.”
It is only natural to be cautious, since once a tooth has been reduced, it cannot be restored.
But did you know that insisting on no-prep without considering the condition of the teeth can actually lead to greater discomfort later on,
or even unnatural results?
The idea that no-prep is always best may be a misconception.
If the teeth are irregularly aligned or already protruded, placing restorations without reduction
can make the teeth appear even more prominent by the thickness of the restoration.
It may also increase discomfort or cause gum inflammation, so for health reasons,
“proper adjustment” is often necessary.
The best candidates for no-prep laminate veneers are
genetically small teeth, called “peg laterals,” or teeth that are set inward.
This is because even when a restoration is placed on the outer surface of the tooth, the overall volume remains within a normal range.
Only when treatment is performed in this kind of space can a thin, beautiful smile that looks like your own teeth be achieved without shaving.
Minimal-prep is not about shaving the tooth down,
but rather about “refining” the surface where the restoration will sit.
Even a tiny adjustment of about 0.1 mm to 0.3 mm can remove the step between the restoration and
the tooth, making the gum line much smoother.
This helps prevent the restoration from coming off and keeps plaque from getting trapped between the gums, extending the life of the teeth.
The success of laminate veneers depends on “enamel,” the hardest outer layer of the tooth.
This is because restorations bond most strongly when they meet enamel.
Even with minimal-prep, if the work is done precisely without going through the enamel,
you can preserve the strength of the natural tooth while achieving beauty, without worrying about nerve damage.
If, when you look in the mirror, one or two teeth seem protruded or slightly misaligned,
you should consider micro-prep rather than no-prep.
Only by very lightly refining the protruding area to correct the angle can the restoration be placed in a way that
does not lift the lips and maintains a comfortable facial line.
This is a case that definitely requires an expert facial analysis diagnosis.
In cases of severe tooth discoloration, no-prep laminate veneers may have limitations.
Because the restorations are so thin, the dark color underneath may show through.
In such cases, micro-prep may be recommended to secure the minimum thickness needed to block the dull color.
It is important to first check the degree of discoloration.
Blanche Dental Clinic’s treatment philosophy is “optimal preservation.”
We believe that the answer is not to avoid shaving at all costs, but to find the “appropriate amount of reduction” so that patients can use their teeth comfortably even 10 years later.
Through 3D scan data, we transparently show the thickness changes before and after treatment,
and propose the most honest and scientific treatment plan.
Rather than thinking that “no-prep” is always better,
consider what method is most natural for your own dental condition.
We share the same desire to take good care of teeth.
