Our Dental Services

From regular teeth cleanings, dental exams, and x-rays to installing beautiful, durable veneers and helping you achieve the smile of your dreams, Smile 312 is the Chicago Loop dentist you can trust.


When it comes to repairing chipped or cracked teeth, veneers are an amazing, minimally-invasive solution. By bonding ultra-thin pieces of porcelain or composite resin to your teeth, we can create a durable solution that looks just like a perfect, natural tooth. Veneers can help you have the smile of your dreams.

A set of custom-made aligners are used to gradually straighten your teeth. The process is more comfortable than traditional braces and the results are just astounding.
