How long dental veneers last cannot be generalized, but is closely related to the choice of materials, post-care and other factors. Veneers are a special material placed on the surface of the teeth to whiten the teeth and protect the surface of the teeth from damage. Currently, veneers can be broadly categorized into two types: resin veneers and ceramic veneers. Resin veneers are convenient and inexpensive, but the resin material ages relatively quickly, and discoloration and chipping will generally occur in 2-3 years. Although the cost of ceramic veneer treatment is more expensive, compared to the former, its service life will be more advantageous, can be maintained for more than 5 years, or even longer. Then there are good post-care measures, can also play a role in extending the life of veneers. In daily life, you should maintain the habit of brushing your teeth regularly and carefully, and reduce the consumption of hard texture, heavy pigmented and other types of food. After veneer treatment, the patient’s mouth may experience a short period of discomfort. During this period, it is necessary to prohibit eating too cold, too hot, too acidic and other types of food, so as not to aggravate the symptoms of tooth allergies.
