A clinic that stands out from the rest: professional and efficient, with a patient experience always very pleasant. Dr. Declercq, who took care of me for 18 months for an Invisalign treatment, is an exceptional practitioner: not only extremely competent, with real attention to detail, but also very human. The confidence that I wear him lives up to my warm recommendation from the Brussels Smile Clinic.

A magical dental practice! Thanks to Dr. Declercq and his team, I have a new dazzling smile and I no longer have any complexes. Following a disastrous experience in another office, the Brussels Smile Clinic team offered me veneers/crowns for all the upper teeth, the result is just incredible (natural and radiant)!!! I felt listened to, I was able to obtain a provisional project in the mouth in order to make modifications and obtain the smile I dreamed of down to the smallest detail. Regarding the firm, all its members were "very caring" with me, with professionalism but above all a rare gentleness (they "whisper" even to each other during the interventions in order to keep a zen atmosphere, I loved !). I was even systematically called the days following the interventions to check that everything was going well, including on Sundays. For having had unfortunate experiences in Brussels, I strongly recommend this firm at reasonable prices and with formidable efficiency in order to have a star's smile ;-)
