Wisdom Tooth Extraction
A common procedure performed by our doctors every day. Trust us for optimal recovery.
Permanent Implants
A tooth replacement that's stronger than the original tooth. A delicate procedure performed by an experienced doctor.
Oral and maxillofacial surgery is based on both dentistry and traditional medicine, as it treats various conditions of the mouth and face. The initial consultation allows us to target the pathology(s) and, if necessary, provide a medical and/or surgical solution.
Some procedures are performed in the clinic under local anesthesia with or without sedation, such as simple or complex dental extractions, implants, apicoectomies, dental exposures for orthodontic purposes, biopsies, treatment of minor infections, and finally, temporomandibular joint treatment.
Other procedures are performed in hospitals and involve bone reconstruction of the jaws and face, treatment of facial fractures, jaw surgery, and cosmetic surgery.

A dedicated clinical team
As highly qualified professionals who perform complex surgical procedures and administer anesthesia, our assistants and nurses are an integral part of our team.
They work alongside the surgeon to provide the best possible care and contribute to patient examinations and diagnoses. They provide a calming and supportive environment for our patients, comfort them during treatments, and advise them on what to expect and what to do in the post-operative days.
Our office staff is the frontline and equally important to our patients' care. They are friendly, courteous, and always ready to warmly welcome both returning and new patients.
They ensure that patients feel comfortable and relaxed during their stay, in addition to organizing and scheduling appointments and follow-up visits at the most convenient times.
Our team speaks several languages, including French, English, Greek, Russian, Romanian, Moldovan, and Spanish.

Wisdom Teeth
Third molars, or wisdom teeth, are the last teeth to appear in our mouths.
When space is insufficient or the eruption angle is unfavorable, the tooth may remain impacted or partially erupt through the gum.
They are then prone to complications such as infection, pain, damage to adjacent teeth, or the formation of cysts or tumors.

Implants
When a tooth is lost, it is recommended to replace it to maintain good teeth.
A dental implant is a type of artificial root made of titanium that is inserted into the jawbone. Once healed, the implant will be fused to the bone, allowing an artificial tooth to be inserted.
It is possible to replace one or more missing teeth, helping to improve the beauty of your smile and the efficiency of chewing.

Pre-prosthetic Surgery
With the loss of natural teeth, changes occur in the gums. When the gums are uneven or have loose tissue, these can affect the comfort and stability of dentures.
Pre-prosthetic surgery is a series of minor surgeries performed on the gums and/or the bone beneath the gums. Once completed, it will allow for the creation of new, more stable, and comfortable dentures.

Oral Pathology
The oral cavity may be the site of abnormal changes in the gums, lips, cheeks, tongue, palate, or throat. These lesions can be benign or malignant.
In such cases, it is advisable to consult an oral and maxillofacial surgeon who will evaluate, diagnose, and treat these lesions.

Sedation
Most surgical treatments offered at our clinic can be performed under local anesthesia. However, in more complex cases or when the patient wishes to remain unaware of the procedure, we can perform the procedure under general anesthesia or intravenous sedation.
Using medication injected into a vein, we can achieve a deep state of relaxation and drowsiness, and upon awakening, with no memory of the procedure.

3D Imaging
Computerized tomography (CT) is used for:
- Diagnosis and treatment of jawbone cysts and tumors
- Identifying the location of impacted teeth
- Assessing the proximity of the third molar to the inferior dental nerve
- Assessing whether there is adequate bone for dental implant insertion

Patient care
Preparation Before Oral Surgery
To facilitate the procedure and make the healing period more comfortable, the following will help:
- Wear comfortable, loose-fitting clothing.
- Prepare soft food before surgery (e.g., jello, applesauce, popsicles, pudding).
- If you are having surgery under IV sedation, you must fast for 6 hours beforehand (do not eat or drink anything).
- If you are having surgery under IV sedation, you must be accompanied by someone, as you will not be able to drive a car or take public transportation home.
- If your health has changed since your last visit, or if you are taking any new medication, please let us know before surgery.
- If you wish, you may bring a selection of music of your choice with you to surgery.
- Please plan a few days off work for your recovery. If you were instructed to take medication before your surgery, please remember to take it one hour before your appointment.
- Surgery fees can be paid by Visa or Mastercard, cash, or debit card.
