01

WaterLase

Advanced 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.

02

CEREC

Single visit crowns and veneers. We scan, design and mill the restoration here, so there is no temporary crown and no second appointment.

03

Invisalign

The clear way to straighten teeth. Dr. Perlin was one of the first Invisalign Premier Providers in the Chicago area.

04

Zoom WhiteSpeed

Philips Zoom in office whitening. One appointment, several shades, supervised start to finish so the gums stay comfortable.

05

AcceleDent Aura

A light, hands free device used alongside aligners to help teeth move on schedule.

06

NeoGen Plasma

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.

What our patients say.

I have been to dozens of dental offices across the country and Smiles by Design is simply the best. A friendly, knowledgeable staff and state of the art instruments in a comfortable atmosphere. But the best part is that Dr. Lina provides a pain free experience, whatever you are having done.
