Tooth discolouration for a variety of reasons can be categorized as internal or external depending on the cause of its occurrence. The reasons for internal or external color change are as follows:
Dental discoloration includes a change in color and damage to the enamel. This is affected by several factors such as consuming inappropriate foods and drinks. Alcohol, tobacco and colored drinks cause discoloration of the teeth and discoloration of the outer layer of the tooth. If this problem is treated promptly and the teeth are whitened, there will be no need for plastering. Besides, failure to treat the outer discoloration can lead to damage to the inner layer of the teeth.
Intrinsic discolouration and change in tooth color may be caused by intrinsic or acquired factors. Some people experience an unavoidable intrinsic discoloration as they age. However, in most people, internal discoloration is caused by acquired factors such as medications, trauma, or tooth decay. Taking tetracycline at some stages of life and excessive use of fluoride can lead to significant change in the teeth. Usually, this type of discoloration cannot be treated with bleaching and bleaching procedures. Therefore, it is recommended to carry out restorative procedures such as veneers and composites.
