  • Replacement of absent teeth with dental implants and bone graphing in the Brits Surgery.
  • Safe replacement of old silver fillings with tooth coloured composite restorations. Porcelain veneers/inlays (Hollywood Smile).
  • Crown and bridge work (porcelain and zirconium’s).
  • Manufacturing Flexi dentures (replacing Acrylic and chrome dentures).
  • Conscious sedation available for children over the age of 4 years as well as for adults for surgical procedures at 25% of theatre costs.
  • Part of the International Team for Dental Implants.
  • Fillings, Root canals, extractions, wisdom extraction, surgical removal of teeth and scale and polishing is also offered.

Cleanliness is our top priority, all dental instruments are sterilized after every patient and electrical equipment has sterile plastic covers to ensure no contamination.

Our practice is a “Mercury free” practice. All filling materials do not contain any harmful materials such as mercury. If old metal or amalgam fillings need to be removed then this is done using specialised techniques to avoid the ingestion of harmful metals. Once these types of fillings have been removed, the teeth are restored with either a composite filling (white filling) or a crown, depending how severe the tooth decay is.



Bridges are done in cases where a tooth has been lost. It is less ideal than an implant, but much better than a removal / partial denture. In simple terms, a bridge consists of teeth crowned on either side of the missing tooth, with a false tooth crown is attached to these crowns.

The advantages of this include
  • Aesthetics,
  • the fact that it is a fixed prosthesis,
  • no surgery is required,
  • and requires limited time to complete.

The disadvantages include more bone loss in the area of a missing tooth than with an implant and that rigorous oral hygiene habits are required.

In cases of missing teeth with inadequate bone available for an implant, a bridge is a good option. The procedure is very similar to that of crowns.


Indications for crowns:

  • Severe tooth destruction, either by fracture or decay.
  • Root canal treatment on a tooth.
  • Cosmetic – in order to correct misaligned teeth, discoloured teeth, or shortened teeth.

The procedure is completed in two appointments. On the first appointment, the tooth is prepared by reducing about 1-1.5 mm circumferentially and 1.5-2mm from the biting surface. Impressions are taken of both jaws using different materials, and a bite registration is performed. Colour selection is also done during this appointment. A temporary crown will be cemented with temporary cement.

On the second appointment, the temporary crown is removed, and the final crown is fitted. If both the dentist and the patient are satisfied with the crown, the crown is cemented with permanent cement.

Different types of crowns exist, including metal crowns with porcelain veneered over it or completely metal free.

Porcelain Veneers

Porcelain veneers are an excellent aesthetic option. A veneer is the replacement of the enamel on the front surface of a tooth with porcelain. This can be done to change the colour of your smile to a more desirable shade, to correct misaligned teeth, or in cases of a chipped tooth where a filling cannot correctly restore the tooth.

The procedure is similar to that of a crown preparation, only it is just the front (buccal) enamel and enamel on the incisor edge of the teeth, which are replaced.

Dental Implants

When a tooth is lost, there are several negative results. The chewing forces transmitted through the tooth to the bone stimulate new bone formation. In the absence of a tooth, the stimulus for new bone formation is missing, resulting in bone loss. The adjacent teeth to a missing tooth will also tilt and move into the gap left by the missing tooth, resulting in disturbances in the bite. Opposing teeth will also over erupt into the space, causing problems with the bite, as well as root exposure and higher risk for caries.

The natural tooth consists of the crown, the visible part above the gum, and the root, found below the gum. An implant is a titanium screw that replaces the root portion of the tooth. A dentist will then place a crown on top of that to complete the procedure.

Implants can also be placed in toothless jaws to help improve stability and retention of full dentures.

During the consultation prior to the procedure, the surgeon will look in the mouth to estimate the width of bone available, and take an x-ray photo to determine the bone height. If there is not enough bone available for the placement of an implant, bone augmentation procedures must first be completed, such as sinus lifts and alveolar ridge augmentation. This will also often determine whether an implant can be placed under local anaesthesia, or whether it needs to be done under general anaesthesia in theatre.

  • Although a punch is sometimes used to open just a small area, most often an incision is made in the gum to expose the bone.
  • A sequence of drills are used to prepare the implant site.
  • The correct size implant is then manually screwed into the prepared site
  • A cover screw is placed on top of the implant
  • Restorable sutures are placed
  • Six months are allowed for the bone to attach to the implant, a process called osseointegration
  • After the six months a second surgical procedure is performed to open the implant and place a healing abutment, which allows the soft tissue to heal in the correct way
  • Ten days after the procedure, the patient can go to the dentist for the crown.
Risk factors for implant failure:
  • Smokers
  • Diabetics
  • People on long term immunosuppressive medication, such as corticosteroids
  • Alcohol abuse
  • Although these are the common risk factors, a very small percentage of implants can fail for no apparent reason. Most of the implant companies will then replace the implant fixture at no extra cost. In the event of implant failure, the implant is removed, the site is left for three months to heal and form new bone, and a new implant can be placed.

NOTE: Titanium is a biologically inert material, and it is not associated with allergies or toxicity.


  • Old metal or amalgam fillings replaced with composite fillings (white fillings).
  • Crowns are usually required when a large cavity threatens the future health of a tooth and are typically bonded to the tooth using a dental cement. A crown is a type of dental restoration which either caps or encircles a tooth or a dental implant.
  • A veneer is a thin layer of material placed over a tooth which either improves the aesthetics of a tooth or to protect any further damage to a tooth’s surface.
  • A dental implant is a “root” device, usually made of titanium and is used to support restorations that resemble a tooth or group of teeth which serves to replace missing teeth.
