Dr Sean 4m dental implant doctor

Dr. Sean Mohtashami

The artist and authority behind the 4M Dental Implant solution and an expert in cosmetic dentistry, Dr. Sean knows how to design a beautiful, personalized smile. 

“The road to excellence is endless.” This is the motto which has inspired Dr. Sean throughout his entire dental career.

In 1998, Dr. Sean opened his first general practice in Las Vegas, Nevada – All Bright Dental. Successful, skilled, and now with several years of experience under his belt, Dr. Sean knew he wanted to do more than just general dentistry. Enrolling in continuing education courses he studied the art and science of cosmetic, reconstructive, and implant dentistry. 

It was then that Dr. Sean became among the first in the Las Vegas valley to take on the dental implant procedure of placing a set of teeth on as few as four implants.

Dr. Sean is not only a perfectionist, but truly an artist and raises smile design to a higher level by taking into account facial features, skin tone, eye color, and more. Dr. Sean has the background and training not just to place implants, but for restoration as well. All this coupled with a cosmetic background equals an aesthetically pleasing and functional outcome for you. Having been trained in all aspects of dentistry, Dr. Sean gives you all your options, so that you can make an informed decision.

As Dr. Sean’s name and reputation grew as a dental implant expert, he traveled around Southern California placing implants as an associate for other dentists. It was only a matter of time before he opened his own dental implant practices there. 4M Dental Implant Center was opened in Newport Beach, with 4M Dental Implant Center Long Beach opening soon thereafter. Both practices handle all aspects of dentistry with a focus on the life changing 4M Dental Implant solution.

Through lectures and seminars, Dr. Sean has been educating fellow dentists and patients about 4M. Recognizing the importance and the huge benefit of the 4M Dental Implant solution, Dr. Sean opened the 4M Institute in Long Beach where dentists world wide come to learn his 4M method. 

Dr. Sean is IV sedation certified.

Dr. Tyler Klein
