Dr. Raj Kumar uses clear aligners to straighten teeth without metal braces. The process involves taking impressions and scans of the teeth, which are used to create a series of custom plastic aligners through 3D modeling and thermoforming. The aligners are worn for two weeks each to gradually shift the teeth into the desired position. They are virtually invisible, comfortable to wear, and allow normal activities like eating. Dr. Kumar has treated over 400 cases with a wide variety of irregularities using this approach.
