Introduction: Bruxism is a parafunctional habit that affects the stomatognathic system and its support structures. Usually associated with stress and mostly occurring at night, bruxism leads to sleep disorders and daily tension headaches. Aiming to rebalance the emotional and physical state of patients, floral-essence therapy lacks side effects or drug interactions, and has been recognized by the World Health Organization. Aim and Methods: The investigators created a buccal-relaxant formula, combining 8 floral essences and testing it in a double-blind clinical assay conducted in bruxism patients. Results: An alcohol solution of the buccal relaxant containing Daughter of Gaia floral essences of Taraxacum officinale, Antirrhinum majus, Fuchsia × hybrida, Bidens bipinnata, Campanula carpatica, Achyrocline, Nymphaea caerulea, and Tetraoensis riparia significantly attenuated temporal headaches in the bruxism patients compared to the placebo group (69.46%±1.79 versus 3.55%±1.37, P=0.0001). Moreover, patients after 21 days using the buccal relaxant increased their quality of sleep and experienced attenuated jaw-muscle rigidity or morning mouth-opening difficulties. Less masseter hypertrophy and reduced sensitivity due to abfraction of enamel facets were noted as well. Conclusions: The buccal-relaxant formula may have sedative properties, preventing daily temporal headaches in sleep-bruxism patients, suggesting a muscle-relaxation effect. Although the results are promising, long-term studies are needed to clarify the pharmacological mechanism of each floral essence in the buccal-relaxant formula and their tolerance effects.
