Abby McDermott, RDH, OMT, CLC


Abby graduated from Dalhousie University with a Diploma in Dental Hygiene in 2018 and enjoyed working in general dentistry and orthodontics for several years. After welcoming her son George and facing their own challenges with breastfeeding and a tongue tie, Abby witnessed firsthand how our health, development and overall well being are directly impacted by the tongue, sleep and breathing. Inspired by this, Abby chose to expand her dental education in the field orofacial myofunctional therapy and added lactation consulting to her skill set. 

Orofacial myofunctional therapy (OMT) is an exercise based treatment modality for symptoms and conditions related to orofacial myofunctional disorders (OMDs). Signs and symptoms related to OMDs include teeth clenching or grinding, TMJD or jaw/facial pain, orthodontic relapse, tongue thrusting, thumb sucking or other oral habits, sleep disordered breathing (snoring or sleep apnea), chronic mouth breathing, recurrent ear infections, bedwetting, night terrors and tethered oral tissues. 

Therapy involves the neuromuscular re-education of dysfunctional muscles of the head and neck. The four goals of therapy include nasal breathing, proper tongue posture, lip seal and correct chewing & swallowing patterns. By achieving these goals and eliminating muscle compensations, individuals see improvements in symptoms and guided craniofacial growth in the pediatric population. 

Abby has dedicated her career to healthy mouths, jaws and airways. When she isn’t taking continuing education courses in breastfeeding or myofunctional therapy, Abby enjoys spending time with her partner Alex, their son George & Labradoodle, Marvin, camping, checking out local restaurants & breweries, and indulging in all of the true crime.
