Dr. Andre Hashem performed a full smile restoration for me using veneers, and I could not be happier with the results. He is not just a dentist—he is an artist. From the very beginning, Dr. Hashem and his entire team supported me through every step of the process, making what could have been an intimidating experience feel comfortable and exciting. My goal was to achieve a more youthful, fuller smile and correct the uneven wear that years of grinding had caused. Dr. Hashem listened carefully to what I wanted and delivered results that exceeded my expectations. The attention to detail, craftsmanship, and genuine care he brings to his work are truly exceptional. I now have a smile that looks natural, healthy, and exactly how I hoped it would. I would highly recommend Dr. Hashem to anyone considering cosmetic dentistry. The experience and results were outstanding. CLICK ON THE PHOTO FOR BEFORE AND AFTER.

I have been going to Smile Design Boston for both general dentistry and orthodontics. They are absolutely top notch. The staff is professional and courteous, the office is modern and very high-end without sacrificing comfort. Dr. Misci is wonderful; she has taken my smile and improved it better than I could have imagined. Dr’s Hashem and Lo are a great team who put their patients first. Their talent is evident in all they do. If you are need of dentistry services in Boston, you cannot make a better choice than Smile Design!!!

I had both crowns and veneers done by Dr. Hashem, and I’m very happy with the results. He is skilled, detail-oriented, and took the time to explain every step of the process, which made me feel comfortable and confident throughout my treatment. Cosmetic dentistry is a big decision, so I appreciated how much care he put into balancing aesthetics with function. My new smile looks natural and balanced while still feeling like me, which was exactly what I was hoping for. The entire team was professional, welcoming, and attentive. I’m grateful for the care I received and would recommend Dr. Hashem to anyone considering cosmetic dentistry.

I’ve had good dentists in the past, but Dr. Lo is truly exceptional. She brings a thoughtful, thorough, & skilled approach to dental care—taking the time to explain options & recommend solutions. I recently had decade-old crowns replaced, a procedure that required precision & the cosmetic artistry to color-match the new enamel to my existing teeth. From removing my old crowns & fitting the temporaries, to cementing the final crowns, the entire process went smoothly. I’m very happy with the final result! Beyond the excellent clinical care, the office setting is calm, pristine, pleasant, & made even better by a welcoming receptionist, Claire. I’d be remiss if I didn’t also mention my dental hygienist, Alessandra, for her excellent work.
