Displaying an excessive amount of upper gum on smiling or laughing can cause incredible anxiety, distress and embarrassment to individuals. It can lead to social behaviours focused on concealing their smile such as covering their mouths or avoiding photographs.

In order to tackle this concern with botox, the upper lip levator muscles need to identified and injected with small doses of botox. The result should ‘gently relax’ but not ‘paralyse’ these muscles. This should limit the upward movement of the lip and reduce the amount of tooth and gum exposure when smiling. The upper lip may appear elongated with a flatter groove (philtrum).

Indication: Gummy smile, which may also present with prominent nose to mouth lines (nasolabial folds).

Muscle Targeted: The levator labii superioris alaeque nasi muscle.

Muscle Action: The vertical fibres of this muscle elevate the upper lip, particularly on smiling. It also contributes to the appearance of the nasolabial folds, the lines that appear from the sides of the nose to the mouth.

Gummy Smile treatment: A small dose of botulinum toxin injected into the muscle just above and lateral to the nostrils. This helps to relax the upper lip and it also appears lengthened, reducing the amount of gum showing when smiling. Nasolabial folds may also be softened.

Possible Side Effects:

  • Smile asymmetry
  • Lip droop
  • Very rare: Difficulty with certain oral functions â?? elocution, eating, drinking
