Botox and fillers can soften fine lines and wrinkles. We will tell you honestly what suits your face.
Better equipment is the shortest route to a shorter, calmer appointment. Everything below sits in our own operatories, so most treatments finish in a single visit.
Ask about a treatmentAdvanced laser dentistry. Many procedures can be done without the drill, and often without a needle, which is why patients tell us the visit felt like nothing at all.
Single visit crowns and veneers. We scan, design and mill the restoration here, so there is no temporary crown and no second appointment.
The clear way to straighten teeth. Dr. Perlin was one of the first Invisalign Premier Providers in the Chicago area.
Philips Zoom in office whitening. One appointment, several shades, supervised start to finish so the gums stay comfortable.
A light, hands free device used alongside aligners to help teeth move on schedule.
For patients who want to avoid fillers. NeoGen supports elastin and the production of collagen, which produces a real change in the volume of the tissue.
Actual patients of Smiles by Design. Results vary from person to person.
Both cases were treated here at 203 N LaSalle. Photography is unretouched, which is why the lighting is not identical between shots.
