Botox for Gummy Smile Treatment

This section describes the types of gummy smiles for which Botox injections are indicated and their treatment.
What is a Gummy Smile?
Gummy smile is a dental term derived from "Gum (gums) + Smile",A condition in which the gums of the upper jaw stand out when smiling.In general, when we laugh, we are laughing. Generally, when you smile.Gums more than 3 mm見えることがガミースマイルの基準だといわれています。
ガミースマイルは、見た目のコンプレックスになりやすいのが特徴。歯茎が気になって、笑うときに口元を隠したり、思い切り笑えなくなったりと仕草や表情がぎこちなくなってしまうことも。
そのほか、ガミースマイルの方は通常よりも口腔内が乾燥しやすいことから、細菌が繁殖しやすい傾向があります。放置していると、虫歯・歯周病のリスクが高くなるでしょう。
What types of gummy smiles can be eliminated with Botox?
ガミースマイルの原因は主に3つあり、複数の原因が絡んでいるケースもみられます。ご自身でガミースマイルの原因を見極めるのは難しいため、クリニックで診断を受けると良いでしょう。
ここでは、主な原因と効果的な治療法をご紹介します。
Front teeth are forward.
When the front teeth are forward, the upper lip tends to rise, causing a gummy smile. In this case, dental braces may reduce gum exposure.
The maxillary bone is protruding forward.
If the maxilla, the upper jaw bone, is protruding forward or if the maxilla is long at the top and bottom, the upper lip will be relatively short, causing a gummy smile. Treatment options include surgery to suture the mucosa of the gums and the mucosa of the upper lip together.
Strong muscle contraction
When the upper lip is pulled up, two muscles in the face are at work. The first is the superior lip elevator muscle, which attaches to the upper lip from the maxillary bone, and the second is the superior lip nasopharyngeal muscle, which attaches to the upper lip and nasal wings from the maxillary bone. If these muscles are highly contractile, the upper lip is pulled up significantly when smiling, exposing the gums. In this case, Botox injections are effective in reducing the movement of the upper lip muscles.
Where to inject Botox for a gummy smile?
Botulinum toxin is "botulinum toxin type A" extracted from botulinum bacteria, which is diluted in saline solution and injected to suppress muscle movement. In the case of gummy smile treatment, it is used to suppress the movement of the upper lip elevator muscle and the upper lip caudalis elevator muscle, which pull up the upper lip,Injections in the area of the left and right laugh linesを打ちます。
施術時間の目安は5~10分程度で、ダウンタイムはほとんどありません。施術後はメイクをして帰ることが可能です。注射の痛みが不安な方には、麻酔を使用して痛みに配慮するクリニックが多くみられます。
What is the effect of Botox for gummy smile treatment?

When do the effects of Botox for gummy smile treatment begin to appear and how long do they last? We will also explain the effects that can be expected in addition to the elimination of the gummy smile.
Duration of Botox Effects
ボトックス注入後、ガミースマイルの改善効果が現れるまでには数日~1週間程度かかり、一般的には2週間経過後に効果のピークを迎えます。
効果の持続期間はAbout 3 to 6 monthsand after that time, the effect will gradually fade and return to normal. To make the effect last longer, it is recommended to inject Botox again before the effect wears off. With regular injections, you can expect the effect to last longer and the symptoms of a gummy smile to become less severe after the effect wears off.
Can be effective in preventing laugh lines.
Botox treatment for a gummy smile can also be used to reduce the appearance of lines. This is due to the proximity of the upper lip ridge elevator muscle, where Botox is injected, to the laugh lines. In addition, the upper lip is no longer raised too high when smiling, which reduces the bite of the laugh lines.
What happens if Botox injections for a gummy smile fail?

Some people may not be willing to undergo Botox treatment because they are concerned about what will happen if it fails. Here we will discuss the disadvantages of Botox injections for eliminating a gummy smile.

Does Botox shortening in the middle of the person lead to a worsening of the gummy smile?
