A dental crown is prostheses that replicates the features of a tooth that it is replacing, and will be fixed onto the tooth after the tooth it is replacing has been cut down. There are a few ways to classify a dental crown, and if it is classified according to its composition, there are three types: porcelain crown, porcelain fused metal (PFM) crown, and metal crown.

When a tooth or multiple teeth are missing, there are a few options for the patient to replace it/them. Two of the most common choices are either by fabricating a bridge, or a removable partial denture (RPD). These two are different in terms of aesthetic and functional aspects, and hence, they have their own indications, as well as advantages and disadvantages. Continue reading →
A dental filling is a dental restorative material used to restore the function, integrity and morphology of missing tooth structure. The structural loss typically results from caries or external trauma. It is also lost intentionally during tooth preparation to improve the aesthetics or the physical integrity of the intended restorative material.
A tooth consists of enamel,dentine, pulp and cementum. Enamel is the outermost layer which forms the crown of a tooth. Tooth surface is covered by a bacterial biofilm,known as plaque. The bacteria metabolizes sugar and releases acid which destroys the enamel. This process is called decay or dental caries. When oral hygiene is inadequate, dental decay progresses into the dentine layer and in later stage, into the pulp. Decayed tooth is weak and brittle, thus it becomes soft, forming what is called cavity. A tooth damaged by decay needs to be filled to restore its normal function, shape and strength.
