The gums under the upper lip being more than 2-3 mm visible when talking or laughing (gummy smile), the upper lip becoming too thin when laughing or smiling, or the tip of the nose being pulled down are all situations that disrupt the smile aesthetics. The most important reason for this problem is that our speech or laughing muscles are stronger than normal and work more. This situation can be corrected by applying Botox to these muscles. The injections are painless and their effects last up to 4-6 months.
