Tooth colored filling or composite filling


It is useful for smaller to mid-size filling on the area when chewing force is moderate. Advantage of tooth colored filling is its natural appearance and required less tooth structure removal as it is bonded to the tooth. Cost is more than silver filling since it required longer time to place. It will stain, discolored and wear over time.
