The goal of this clinical trial is to compare the effects of photobiomodulation with red laser on gingival graft donor areas of the palate in comparison to only protection with wound dressing. The main questions it aims to answer are: Does photobiomodulation on the palate promote faster somatosensory recovery? Does photobiomodulation reduce pain in palate donor sites, improving the quality of life? Participants who need gingival graft surgeries will receive laser irradiation on the palate donor area or just protection with wound dressing. Data will be collected up to 60 days. Researchers will compare protection on the palate and protection plus laser irradiation to see if laser therapy may reduce pain and accelerate somatosensory normalization. Moreover, they will measure changes in the quality of life after treatment.

Inclusion Criteria:

• Palate with normal and healthy mucosa
• Patient with indication of gingival graft surgery

Exclusion Criteria:

• Patients using prosthesis with palate coverage
• Former removal of gingival graft in the palate
• Smokers
• Pregnancy and breastfeeding mothers
• Use of anticonvulsants and immunosuppressors

Patients will be masked by using a sham laser. Outcomes assessor will not be able to identify the experimental groups
