About Brentwood Dental Group
Dr. Seth Wasson and colleagues draw adults seeking Invisalign, with reviews describing gap closures, overbite correction, and cases finished in as little as three months.
Brentwood Dental Group is a general dental practice that also offers Invisalign for patients seeking straighter teeth. Adults account for a notable share of the feedback, including several who transferred mid-treatment from other practices and continued care smoothly here. Dr. Seth Wasson and other current dentists are frequently credited with calm, gentle handling of anxious or long-hesitant patients, and the office describes step-by-step explanations of diagnosis and cost before work begins. A handful of reviews raise billing discrepancies and inconsistent price quotes, which is worth keeping in mind alongside the largely positive feedback.

10/10, everyone was super welcoming and the office was very clean. Jillian , my hygienist explained everything very well and answered all of my questions !
I don’t like going to the dentist. It’s a childhood fear that follows me. But the team at Brentwood Dental is so kind and supportive. I really appreciate them!
I was able to get in with an appointment for a time slot that opened up in short notice and they were great making everything work. Such as looking up my Delta info, to making it happen with the X-rays and being flexible with everything . All in the morning before my early morning appointment. I now have a follow up I badly needed and I have my teeth cleaning scheduled I so often never totally utilize. I am happy it worked out
Seth is amazing at what he does. I’ve been going here for 7yrs. No disappointment. Love the staff, friendly and supportive. I would’ve never thought I'll get Invisalign one day. Choosing Brentwood Dental Group was the perfect option. I grew up with a gap and overbite. I decided to close my gap to see another pov of myself and fell in love ever since. Highly recommend!
My go-to teeth shiners! They're friendly, knowledgeable and accommodating. Sometimes I have to reschedule and they're amazing! My teeth have never felt better!
