With effect from 1 January 2008 tax relief is allowable for expenditure on core preparation for crowns and temporary conditioning crowns.


Etched Fillings

These are a type of crown.

Tip replacing

This is regarded as a crown where a large part of the tooth needs to be be replaced and the replacement is made outside the mouth.

Post & Core

These are inserts in the nerve canal of a tooth, to hold a crown. With effect from 1 January 2008 tax relief is allowable for post and core build-ups made from materials other than gold.


An inlay is a smaller version of a crown. However, tax relief is only allowed if the inlay is fabricated outside the mouth. With effect from 1 January 2008 tax relief is allowable for inlays made from materials other than gold.

Endodontic - Root Canal Treatement

This involves the filling of the nerve canal and not the filling of teeth.

Peridontal  Treatement

The following treatments qualify for tax relief:

- Root Planting, which is a treatment of periodontal (gum) disease

- Currettage and Debridement, which are part of root planing
- Gum Flaps, which is a gum treatment

- Chrome Cobalt Splints, if used in connection with periodontal treatment (if the splint contains teeth, relief is not allowable)

- Implants following treatments of periodontal (gum) disease which included bone grafting and bone augmentation.

Orthodontic Treatement

This involves the provision of braces and similar treatments. With effect from 1 January 2008 tax relief is allowable for the cost of temporary implants in circumstances where they form part of the overall orthodontic treatment.

Surgical Extraction of Impacted Wisdom Teeth  

Relief is allowable when undertaken in a hospital or by a dentist in a dental surgery.



Dental Treatment consisting of an enamel-retained bridge or a tooth-supported bridge is allowable.

Note: Tax legislation specifically excludes relief for expenditure incurred on the extraction, scaling and filling of teeth and the provision and repairing of artificial teeth or dentures. These items are excluded from relief even if there is an underyling medical condition that gives rise to the dental treatment or if the treatment in a particular case is considered to be of a non-routine nature.
