Invisalign® (no more wires, no more braces) in Milpitas, CA

Dr. Alejandro Celis is a preferred provider of Invisalign®. Invisalign helps to create healthier gums, improve your oral hygiene (prevention of gum disease)  and decrease abnormal wear (notches, attrition) on posterior and anterior teeth preventing teeth sensitivity, plaque retention, decay, fracture and uneven smile.

Invisalign es la forma mas precisa de alinear los dientes, sin la necesidad de colocar alambres de metal ni tampoco brackets o bandas. Tener Dientes alineados no es solo Estetica es tambien evitar el dano irreversible producido por tener una mordida defectiva, como degaste prematuro de los dientes ( en el borde ) o de las muelas ( en la superficie de mordida ).Es tambien prevenir caries, fracturas de dientes, sensibilidad, retencion de placa y una sonrisa mal-alineada.

"We are Investing in Dental Technology to achieve Excellence in Dentistry " Drs. Celis



We love to do Dentistry, for us it is a passion, a blend of art and science, a symbiosis...and the addition of Digital technology helps us provide a better and more accurate diagnosis and treatment results. It makes our everyday Dentistry more precise, perfect and enjoyable. Thinking of enjoyable , we just incorporated the Intra-Oral Scanner into our practice in Milpitas. In other words no need to have an impression taken...no goop, no gag. The Oral-scanner records the tooth preparation and its surroundings and then sends the file electronically to our Dental Lab. The result is a Computer-designed Ceramic Crown, Veneer or Implant Crown that fits perfectly and restores the function just like a new tooth.
