Non-subsidised Dental Treatments

Find out more about non-subsidised dental treatments, from dental crowns to dentures and wisdom tooth extractions, and which dental clinics to visit for these unsubsidised dental services.

The National Healthcare Group (NHG) provides unsubsidised intermediate dental services, such as dental crowns and bridges, wisdom tooth extractions, root canal therapy, dentures, teeth whitening and other aesthetic services. These services include: 

Routine Dental Care

Check-ups enable you and your dentist to remain up-to-date with your oral health status. During consultation and treatment planning, your dentist will evaluate the health of your gums, check for cavities, check the margins of previous fillings and restorations, screen for oral cancer and other oral diseases, and evaluate your jaw alignment. 

He may also take X-rays, carry out professional cleaning to remove plaque and stain build-up, and apply fluoride. Regular dental visits allow problems to be identified early. Your dentist will also guide you on steps to take to maintain healthy teeth and gums. 

Scaling and Polishing

Scaling and polishing can be done by dental surgeons at NHG’s non-subsidised dental clinics.

Scaling is a treatment which gently removes plaque and calculus deposits without harming your teeth. The hardened tartar that sticks to the teeth can be removed by using a specialised ultrasonic scaler.

Polishing is carried out after scaling to remove stains. Polishing is done using a special toothpaste-like material with a soft rubber cup that spins around the teeth. Scaling and polishing is important as they:
Remove tartar, helping to prevent gum recession and gum diseases — the main causes of shaky teeth and tooth loss
Remove stains caused by food such as coffee/tea or tobacco
Facilitate the screening of oral diseases such as cavities and tooth decay

Teeth Whitening

Tooth discolouration and staining are a relatively common problem. Teeth are porous and are therefore not stain-resistant. Red wine, soda, coffee and tea, among other food and drink, contribute to the discolouration of teeth over time. Medication such as the antibiotic tetracycline can cause significant staining, resulting in yellowish or greyish teeth. Smokers’ teeth can become permanently stained if the discolouration is not treated in a timely manner. Discolouration can also occur due to conditions such as fluorosis, abnormal development of the teeth and dental caries.

A consultation with your dentist before you begin any teeth whitening treatment is important in order to determine the best method for you.

There are a few options to choose from when considering teeth whitening.

Dentist supervised at-home whitening — a daily bleaching process that can be continued until the patient is happy with the appearance of their teeth. The dentist prepares a custom-made mouth-guard bleaching tray. The whitening gel is added to the inside of the tray and applied to the teeth for several hours each day. Good results occur in one to three weeks.

In-office light-activated (laser) whitening — a system whereby a light source activates the bleaching gel which is applied to the teeth by the dentist. The treatment takes one to two hours and can whiten up to eight shades in one treatment.  

Bonded Fillings

These are composite (white) fillings that can be used in place of amalgam (silver) fillings in many cases. It is a more attractive alternative to amalgam fillings as it actually bonds to the tooth for a tight seal. These fillings are strong, stain-resistant and can be colour-matched to the natural tooth, making them unnoticeable. Composite fillings are especially suited for smaller cavities and for patients who may be allergic to metal fillings.


A tooth extraction is the removal of a tooth from its socket in the bone. If a tooth has been damaged by decay or a fracture, your dentist will try to repair and restore it with a filling, crown or other treatment. Sometimes though, the damage is too extensive for the tooth to be repaired. This is the most common reason for extracting a tooth.

Wisdom Teeth Extraction

Wisdom teeth or third molars are the final teeth to develop. Wisdom teeth that are healthy and properly positioned can be a valuable asset to the mouth. Unfortunately, this is often not the case and problems develop that require their removal. For example, when the jaw is not large enough to accommodate these teeth, they can become impacted — unable to come in or move into their proper place. Impacted wisdom teeth can cause crowding, displacement, decay, infection or gum disease. After examining your mouth and taking X-rays, your dentist will discuss whether your wisdom teeth should be removed.

Extractions of wisdom teeth may be performed by a general dentist. If your dentist anticipates any problems he may refer you to an oral and maxillofacial surgeon; a dentist who specialises in surgery and the removal of wisdom teeth.

Root Canal Therapy

Root canal therapy treats disorders or infection of the nerve (also called the pulp) inside the tooth. Root canal treatment involves the partial or total removal of the tooth’s pulp, a small thread-like tissue that was important for tooth development. Once totally removed, it is replaced with materials that seal off the root canal from bone supporting the tooth’s root; a fully developed tooth can function normally without a pulp.


These are thin, tooth-coloured porcelain or composite shells which are carefully crafted to bond to and cover the front surface of unsightly teeth. A small amount of tooth must be removed during preparation for veneers.


Crowns strengthen and protect the tooth structure and can improve the appearance of your smile. A crown is a dental restoration that entirely covers or "caps" a tooth. Your dentist may recommend a crown to:
Replace a large filling when there isn’t enough tooth remaining
Protect a weak tooth from fracturing
Restore a fractured tooth
Attach a bridge
Cover a dental implant
Cover a poorly shaped tooth or
Cover a tooth that has had root canal treatment

Types of Crowns

Full porcelain crown
Porcelain-fused to-metal crown
All-metal crown

Fitting a crown requires at least two visits to the dentist’s office. In some cases, an additional visit may be needed for adjustments. Initially, the dentist shapes the outer portion of the tooth, takes an impression and makes and fits a temporary crown. In a subsequent visit, the dentist will remove the temporary crown and fit and make any adjustments to the final crown. Once the patient and dentist approve of the final crown, it will be cemented permanently into place.

Dental Bridge

Dental bridges are used to replace missing teeth. There are several types of fixed dental bridges; conventional fixed bridges, cantilever bridges and resin-bonded bridges. A resin-bonded bridge requires less preparation of adjacent teeth. It is often used to replace front teeth, provided that the gums are healthy and the surrounding teeth do not have extensive dental fillings.


A denture is a removable prosthesis used to replace missing teeth. Commonly referred to as “false teeth”, it is usually made of acrylic or a combination of acrylic and metal. A partial denture is fitted to replace some missing teeth whilst a complete denture is indicated when all natural teeth are missing. A good set of dentures helps you to eat, speak and function, and often makes the person looks better. Like natural teeth, dentures can accumulate plaque and food debris, particularly in areas where the denture is in contact with the remaining teeth and gum. In addition to the usual oral hygiene measures like tooth brushing, dentures should be cleaned regularly. Poor denture hygiene can result in stains on the denture, bad odour, and sometimes infection of the gum areas.

CEREC (CEramic REconstruction)

CEREC® from Ceramic Systems is an acronym for CEramic REConstruction and an exciting new technology in dentistry — the application of industrial CAD/CAM techniques to the restoration of individual teeth. CEREC is an in-surgery computer system that allows us to replace damaged tooth structure with a ceramic material that is as close to natural teeth as possible. This is all done while you are in the surgery. With CEREC there are no temporary restorations, no impressions, no two-week wait while the laboratory fabricates the restoration and no second appointment.

All-ceramic inlays (fillings), veneers and crowns that look and feel like natural teeth, can be made and fitted in a single appointment, usually in about an hour.

No temporary restorations
