Hello.

Blanche Dental is where your smile becomes a work of art.

A smile is an important factor in determining first impressions.

However, many people lose confidence in their smiles because of so-called

'Gummy Smile,' where the gums are excessively exposed when smiling.

If you have been worried, thinking, "Do I have to cut away all the gums?" or "Wouldn’t surgery be too extensive?"

please find a healthy and natural solution through today’s article.

People with a gummy smile commonly feel that "their lips can’t be controlled when they smile."

This is when the lips unintentionally lift, exposing the gums.

This occurs when the muscles that lift the lips are strong, regardless of one’s intention, or

when the gums cover too much of the teeth, so identifying the exact cause comes first.

Many people mistakenly think that solving gum exposure requires a major surgery that involves shaving bone.

However, if there is no severe protrusion of the skeletal structure itself, there is a conservative method called

oral vestibuloplasty (lip repositioning surgery) that limits how far the lips can rise.

If you have only been worrying because of a vague fear of surgery, you can now feel at ease.

Oral vestibuloplasty is a procedure that newly rearranges the space (the vestibule) between the inner lining of the lips and the gums.

The principle is to create a support point so the lips are not pulled upward too much when smiling.

Because it does not excessively remove gum tissue or involve the bone, it places less physical burden on the body and

has the advantage of showing immediate improvement in the smile line after the procedure.

One of the main causes of a gummy smile is when the philtrum muscles pull the lips too strongly.

There are temporary methods such as Botox, but oral vestibuloplasty

physically resets the path of lip elevation, creating a more fundamental change.

With a micro-adjustment of 0.1 mm, it is a precise procedure that preserves your usual facial expression while reducing gum exposure only when smiling broadly.

It is not just about changing the position of the lips; the amount of gum covering the teeth must also be checked.

If the teeth look unusually short, it is good to combine the procedure with minor gum contouring

to balance the width-to-height ratio of the teeth.

Only when the position of the lips and the amount of tooth exposure are in harmony is the most ideal 'smile line' completed.

The most aesthetically pleasing smile is when the upper lip

just slightly rests on the boundary of the teeth, or when 1–2 mm of the gums are visible.

If 3 mm or more of the gums are broadly exposed and causing concern, you may consider gummy smile correction.

This may be related not only to an unattractive appearance but also to

issues with mouth breathing, which can cause dryness in the mouth, so please check for that as well.

For people whose upper lip curls inward when smiling

and whose philtrum looks short, oral vestibuloplasty can be a very good alternative.

However, because the amount of tissue around the lips and the degree of elasticity differ from person to person,

a one-size-fits-all procedure should be avoided.

A customized treatment plan that matches the shape of your lips and muscle movement is the key to successful results.

Blanche Dental does not focus only on covering the gums.

We perform 'dynamic smile analysis' to see how a patient’s impression changes when speaking or smiling broadly.

When repositioning the lips, we use conservative surgical techniques to support recovery, and even after the procedure,

we maintain a one-on-one customized treatment system so that you can smile naturally without awkwardness.

There is a way to brighten your appearance while preserving as much of your teeth and gums as possible.
