About 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.

It was all good , professional service and nice attention from the personnel.
Great office, always a good experience. My whole family goes there since 2006 and we all love their services.
I felt the hygienist was very thorough in cleaning my teeth. She also closely inspected them for problem spots. I waS happy to be told my teeth looked good.
I’ve been with Dr. Tonnu my whole life, and I genuinely couldn’t ask for a better dentist! She is seriously the sweetest and most wonderful doctor ever. You can tell she really knows what she’s talking about, and she always takes the time to make sure everything goes smoothly and that you’re comfortable throughout the entire experience. She’s extremely professional, but at the same time SO funny and personable, which makes going to the dentist actually enjoyable!! She always makes you feel comfortable and confident, especially once she’s done fixing up your teeth. Her office also has such a warm, homey feeling and is always decorated so nicely for every season, which I’ve always loved. You can tell she genuinely cares about her patients and the experience they have in her office. I ❤️ my dentist so much and honestly couldn’t imagine going anywhere else. Choosing Dr. Tonnu as your dentist would probably be one of the best decisions of your life!! 🦷💕
