A Street Dental

A Street Dental is at 713 A Street in downtown Hayward — within walking distance of the Hayward BART station and accessible from the surrounding Mission and downtown residential neighbourhoods. The practice is led by Dr. Quynh Tonnu and serves the diverse Hayward community from a transit-accessible downtown address that removes the car-dependency that limits access to many suburban dental offices.

NightLase is listed as a distinct service — a laser-based treatment for snoring and mild obstructive sleep apnea that is uncommon in general dental practices. NightLase uses an Nd:YAG laser delivered intraorally to tighten the soft palate and uvular tissue through photothermal collagen remodelling. The thermal effect contracts existing collagen fibres and stimulates new collagen formation, reducing the palatal laxity that causes vibratory snoring and, in mild OSA, contributes to airway collapse during sleep. The procedure is non-invasive, requires no anaesthesia, and is typically completed over three treatment sessions.

Sleep apnea treatment is also listed as a separate service — likely oral appliance therapy using mandibular advancement devices for patients with mild-to-moderate obstructive sleep apnea needing a positional airway intervention. Having both NightLase (for snoring and very mild OSA) and mandibular advancement devices (for mild-to-moderate OSA requiring more active airway management) at the same address gives Dr. Tonnu's practice a more complete non-CPAP sleep dentistry toolkit than is typical in general dental offices.

Oral cancer screening at downtown Hayward provides clinical value in a community context where tobacco use and other risk factors are statistically higher than in more affluent Bay Area cities. Integrating visual and tactile mucosal examination into the routine appointment — for patients who may not otherwise access head and neck cancer screenings — provides early detection value that is disproportionate to the time required for the examination.

General dentistry, root canal treatment, dentures, veneers, and mouth guards round out the service profile. Custom mouth guards for bruxism prevention or sports protection are a high-value preventive service at any general practice. For downtown Hayward patients who commute via BART or live in the surrounding Mission district and want a practice with laser sleep treatment, oral cancer surveillance, and core restorative services, A Street Dental's transit-adjacent address covers that clinical combination.
