About William M Cohen, DMD, MS
My name is Dr. William Cohen and I am a board-certified Periodontist in the State of Missouri. I have devoted my professional career to all aspects of periodontics with special interests in the treatment of periodontal disease and implants.
I am 100% devoted to my patients and am always available. My interest in each patient’s course of treatment extends beyond the care received in my office. I coordinate closely with your general dentist and I always strive for the very best results.
My training began with a four-year degree in Biology from the University of Missouri – Columbia. After I received a Doctorate of Dental Surgery from Washington University I received a Masters of Science and a Certificate of Advanced Studies in Periodontics from the University of North Carolina – Chapel Hill. In 1990 I received the prestigious National Institute of Dental Research Fellowship to study the relationship of inflammation and blood coagulation.
My devotion to the profession extends beyond patients to teaching and mentoring. Since 2000 I have maintained an Associate Assistant Professorship in the School of Dentistry’s Periodontics Department at the University of North Carolina in Chapel Hill. I am an Attending Faculty Member and I teach clinical, surgical, and didactic training to periodontal residents.
To keep abreast of the latest developments in periodontics I regularly exceed the continuing education requirements for my profession as prescribed by the State of Missouri. I share my knowledge and insights throughout my profession by lecturing throughout the U.S. and inviting students, dentists, and fellow periodontists to visit my office to observe me perform the latest periodontal therapies and implant techniques.
I am a member of the American Dental Association, the American Academy of Periodontology, the Missouri Society of Periodontology, the St. Louis Dental Society and the St. Louis Study Club.
My accomplishments would not be possible without the support of my understanding wife and three wonderful children. As a native St. Louisan I enjoy golfing, fishing, cycling, running and of course the St. Louis Cardinals.

Dental Implants
A dental implant is a root-form titanium screw that is surgically placed in the jaw to create an anchor for teeth to be built upon. Dental implants are considered the best way to replace missing teeth.

Single Posterior Implant
The majority of dental implants involve the replacement of a back tooth. Referred to as a single posterior implant, this procedure is typically less complex and less costly than many people expect.

Front Tooth Implant
Dental implants are an excellent option for replacing a missing front tooth in most cases. Front tooth implants are not as common as dental implants replacing missing molars or back teeth.

Same Day Implants
With same day or immediate load implants, you can potentially receive both your implant surgery and your new teeth on the same day. However, there can be more associated risks and complications.

Mini Implants
Mini dental implants, sometimes referred to as MDI or narrow-diameter implants, can be an excellent option if you’re looking to replace lost teeth in areas with less bone volume or severely limited spacing.

Full Mouth Implants
Missing most or all of your teeth due to damage, periodontal disease, or tooth decay? Full mouth dental implants, which your dentist may call full mouth restoration or reconstruction, can be a great option.

Tooth Extractions
Sometimes referred to as “having a tooth pulled,” a tooth extraction is a very common oral surgical procedure in which a natural tooth is removed from the jaw. An implant may be placed after adequate healing time.

Bone Grafting
After teeth are extracted, bone can atrophy or shrink to the point that bone grafting is required. Bone grafting builds up bone foundations for sufficient implant stability and strength.

Socket Preservation
Socket preservations are simple bone grafting procedures done in conjunction with tooth extractions. The goal of socket preservation is to preserve bone for a future dental implant to be placed.

Dental Crowns
A dental crown is a cap or cover that protects the tooth and restores it to mimic natural shape, size, and function. Crowns are make of zirconia or porcelain and can be either cemented or screw-retained.

Screw Retained Crowns
A screw-retained implant crown is a single-tooth fixed restoration that is secured to a dental implant by means of a screw. Screw retained crowns are popular due to the proven long-term success they deliver.

Cemented Crowns
A cemented crown is a dental crown that is secured to a dental implant using a luting agent similar to dental crowns cemented onto natural teeth. Cemented crowns are beautiful, functional, and extremely durable.

Implant Cosmetics
The goal of implant cosmetic dentistry is to create tooth-like restorations that are strong, mimic natural beauty and completely restore natural function. Think of cosmetic dentistry as plastic surgery for teeth.

Thank god for Doctor Cohen. I can't even put into words how great he is. Dr. Cohen genuinely cares about his patients and really knows what he's talking about. He is a literal life saver. Everyone working in his office is great too, Barry always makes me feel welcome and the receptionist is on point! I'm so glad I found them to help with my blood clot resulting from a knee surgery. I would recommend this office to anyone having similar struggles.
