Cavities develop from many reasons, however the biggest cause is usually due to a high sugar diet and a lack of proper oral hygiene. Early signs appear as sensitivity to sweet or cold and dark discolouration.
Types of restorations:
White fillings are adhesive fillings that are used to repair teeth affected by decay, crack or fractures.
Porcelain fillings otherwise known as inlays or onlays are an alternative restoration to composite fillings.
Ideal candidates for inlay or onlay work typically have too much damage or decay in the tooth structure to be successfully treated using a composite filling, but have sufficient healthy tooth remaining to avoid the need for a crown.
Crowns are used to protect and strengthen heavily filled teeth and restore damaged, decayed or broken teeth. They are placed over the tooth restoring it to its original shape, size and colour.
