Bridges (also known as fixed partial dentures) are used to replace a missing tooth by joining permanently to adjacent teeth or dental implants. In essence, we are bridging the gap.

The teeth on either side of the gap will essentially be crowned, with a fake tooth (pontic) in between them. The bridge will be a solid unit with the appearance of three separate teeth.

An implant supported bridge can be used when several teeth in a row are missing. Typically one or more implants will be placed and crowned and pontics will fill in the remaining gaps.


A crown is a type of dental restoration which completely caps or encircles a tooth or dental implant. Similar to onlays, crowns are often needed when a large cavity or fracture threatens the ongoing health of a tooth. Crowns may also be necessary following a root canal.

Crowns are fabricated outside of the mouth and typically made of porcelain. Usually two appointments are associated with crowns. A temporary crown is placed at the first visit while the permanent prosthesis is custom-made. A second visit is required in order to fit the permanent crown.

While crowns may be costlier than direct restorations, they are superior in terms of resistance to occlusal forces, protection against recurrent decay, precision of fabrication, marginal integrity and ease of cleansing.

Dental Implants

A dental implant is a "root" device used in dentistry to support restorations that resemble a tooth (or group of teeth) to replace missing teeth.

Virtually all dental implants today are placed within the jaw bone. The bone of the jaw accepts and fuses with the titanium post. Once the post has attained this fusion, we will expose it and place the rest of the post, onto which we can then attach the prosthetic tooth or teeth.

Dental implants can only be used to support a number of dental prosthesis, including crowns, bridges and dentures. They can also be used as anchorage for orthodontic tooth movement.

Dental implants can be costly, however they are the most natural replacement for missing teeth and are often superior in comfort.

Dr. Gauthier holds a fellowship in the International Congress of Oral Implantologists (ICOI).  Please see for more information.


Dentures (also known as false teeth) are prosthetic devices constructed to replace missing teeth which are supported by surrounding soft and hard tissues of the oral cavity. Conventional dentures are removable, however there are many different denture designs, some of which rely on bonding or clasping onto teeth or dental implants. There are are two main categories of dentures, depending on whether they are used to replace missing teeth or the mandibular arch or the maxillary arch.


Dentures can help patients in a number of ways.

  1. Mastication - chewing ability is improved
  2. Aesthetics - the presence of teeth provides a natural facial appearance and wearing a denture to replace missing teeth provides support for the lips and cheeks and corrects the collapsed appearance that occurs after losing teeth.
  3. Phonetics - by replacing missing teeth, especially the front teeth, patients are better able to speak
  4. Self-Esteem - Patients feel better about themselves.

Types of Dentures

Removable partial dentures are for patients who are missing some of their teeth on a particular arch.

Conversely, complete or full dentures are worn by patients who are missing all of the teeth in a single arch (upper or lower).


A dental extraction is the removal of a tooth from the mouth. Extractions are performed for a wide variety of reasons, including both decay that has destroyed enough tooth structure to render the tooth non-restorable. Extractions of impacted or problematic wisdom teeth are routinely performed as are extractions of some permanent teeth to make space for orthodontic treatment.

Extractions are often categorized as 'simple' or 'surgical'.

Simple extractions are performed on teeth that are visible in the mouth, usually under local anesthetic and require only the use of instruments to elevate and / or grasp the visible portion of the tooth.

Surgical extractions involve the removal of teeth that cannot be easily accessed either because they have broken under the gum line or because they have not erupted fully. Surgical extractions almost always require an incision. Frequently the tooth may be split into multiple pieces to facilitate it's removal.


A dental restoration (filling) is used to restore the function and integrity of missing tooth structure. The structural loss is typically caused by decay or trauma.

Dental restorations can be divided into two broad types: direct restorations and indirect restorations.

Direct restorations involve removing the damaged or decayed tooth structure and then building up the tooth with a malleable material. The advantage of direct restorations is that they usually set quickly and can be placed in a single procedure. Since the material is required to set while in contact with the tooth, limited energy can be passed to the tooth from the setting process without damaging it. Where strength is required, especially as the fillings become larger, indirect restoration such as crowns, inlays or onlays may be the best choice.

Inlays and Onlays

In dentistry, an inlay is an indirect restoration consisting of a solid substance (as gold or porcelain) fitted to a cavity in a tooth and cemented into place. An onlay is the same as an inlay, except that it extends to replace one or more cusps. Crowns are onlays which completely cover all surfaces of a tooth.

An inlay may be indicated if decay or fracture is so extensive that a direct restoration (filling) would compromise the structural integrity of the restored tooth. When an inlay is used, the tooth to restoration margin may be finished and polished to such a super fine line of contact that recurrent decay will be all but impossible.

An onlay may be indicated when the fracture or decay affects one or more cusps, compromising the perimeter walls of the tooth. An onlay allows for conservation of tooth structure and may be an alternative to restoration with a crown.

Inlays and onlays are fabricated outside of the mouth and typically made of porcelain. Usually two appointments are necessary. A temporary inlay or onlay is placed at the first visit while the permanent prosthesis is custom-made. A second visit is required in order to cement the permanent inlay or onlay.

Root Canals

Endodontic therapy is a treatment for the pulp of a tooth which results from the elimination of infection and protection of the decontaminated tooth from future microbial invasion. This set of procedures is commonly referred to as a "root canal".

Root canals and their associated pulp chambers are the physical hollows within a tooth that are naturally inhabited by nerve tissue, blood vessels and other cellular entities. Endodontic therapy involved the removal of these structures, the subsequent cleaning, shaping and decontamination of the hollows with tiny files and irrigating solutions and the filling of the decontaminated canals with an inert product.

After endodontic surgery the tooth will be "dead" and since the structural integrity of the tooth may now be compromised, an onlay or crown may be necessary to improve the strength of the remaining tooth structure and prevent future fractures.


What are dental sealants?

Dental sealants are thin plastic coatings that are applied to the grooves on the chewing surfaces of the back teeth to protect them from tooth decay. Most tooth decay in children and teens occurs on these surfaces. Sealants protect the chewing surfaces from tooth decay by keeping germs and food particles out of these grooves.

How are sealants applied?

Applying sealants does not require drilling or removing tooth structure. The process is short and easy. After the tooth is cleaned, a special gel is placed on the chewing surface for a few seconds. The tooth is then washed off and dried. Then the sealant is placed on the tooth. The dentist or dental hygienist also may shine a light on the tooth to help harden the sealant. It takes about a minute for the sealant to form a protective shield.

How long will sealants last?

A sealant can last as long as 5 to 10 years. Sealants should be checked at your regular dental appointments and can be re-applied if they are no longer in place.

Which teeth are suitable for sealants?

Permanent molars are the most likely to benefit from sealants. The first molars usually come into the mouth when a child is about 6 years old. Second molars appear at about age 12. It is best if the sealant is applied soon after the teeth have erupted, before they have a chance to decay.

As with anything new that is placed in the mouth, a child may feel the sealant with the tongue. Sealants, however, are very thin and only fill the pits and grooves of molar teeth.

Why is sealing a tooth better than waiting for decay and filling the cavity?

Decay damages teeth permanently. Sealants protect them. Sealants can save time, money and the discomfort sometimes associated with dental fillings. Fillings are not permanent. Each time a tooth is filled, more drilling is done and the tooth becomes a little weaker.

Will sealants make the teeth feel different?

As with anything new that is placed in the mouth, a child may feel the sealant with the tongue. Sealants, however, are very thin and only fill the pits and grooves of molar teeth.

Teeth Whitening

Dental bleaching, also known as tooth whitening, is a common procedure in general dentistry. A child's deciduous teeth are generally whiter that the adult teeth that follow. As a person ages, the adult teeth often become darker due to changes in the mineral structure of the tooth as the enamel becomes more porous. Teeth can also become stained by bacterial pigments, foodstuffs and tobacco. Certain antibiotic medications (like tetracycline) can also cause teeth stains or a reduction in the brilliance of the enamel.

Traditionally, at home whitening involves applying bleaching gel to the teeth using thin guard trays. Impressions will be taken so that bleaching trays can be custom made. Custom made trays are preferable to standard trays as they will help keep the bleaching gel away from the gums.

The effects of bleaching can last for several months, but may vary depending on the lifestyle of the patient. Factors that decrease whitening include smoking and the ingestion of dark coloured liquids like coffee, tea and red wine.


In dentistry, a veneer is a thin layer of restorative material placed over a tooth surface, either to improve the aesthetics of a tooth or to protect a damaged tooth surface. There are two main types of material used to fabricate a veneer: composite and dental porcelain. A composite veneer may be directly placed (built up in the mouth) or indirectly fabricated by a dental technician in a dental laboratory and later bonded to the tooth, typically using a cement. In contrast , a porcelain veneer may only be indirectly fabricated.
