The enamel of your tooth may get lost due to cavities or may have to be removed during the Root Canal Treatment. Unfortunately, the enamel doesn’t grow back, and so once a hole is created, then the only thing to do is tooth restoration i.e. to fill it in with something that imitates enamel.
Composite dental fillings are created from plastic and resin material. It is placed inside the tooth while it is soft and hardened with a bright curing light. It is a common option because it can be customised to match the colour of the patient’s existing teeth.
Ceramic fillings, usually made up of porcelain, are also used to cover up cavities. Ceramic fillings are tough and tend to last long. They come in the form of Inlays and Onlays. The drawback of using ceramic filling over composite is that it is more brittle and, therefore, has to be used on large cavities to prevent breakage.
However, in case of major fillings, where the healthy tooth is not much left, it is highly advisable to complement these with dental crown which have higher strength and life.
