For many patients, the idea of dental staining seems like an issue that affects only the exterior of the tooth, and is corrected through topical bleaching treatment. At the dental practice of Laura Randolph, DDS, we provide options to correct stains on the surface as well as from within the structure of the tooth.
This guide will help you to understand how discoloration occurs from within the tooth and how such stains can be corrected.
Causes of Intrinsic Staining
Dental Fluorosis: One of the primary causes of intrinsic staining is dental fluorosis, which occurs when excessive amounts of fluoride are ingested, causing the enamel to re-mineralize faster than it demineralizes, creating white spots. This can be avoided by checking whether your city water supply is fluoridated, and if so, consulting your dentist to determine whether fluoridated toothpaste and mouthwash would contribute to excessive mineralization of teeth.
Tetracycline: Another common cause for intrinsic discoloration is the use of the antibiotic tetracycline. While not as commonly prescribed in the current medical environment, some patients are still given tetracycline to combat acne. Other patients may have been given this medication years ago in childhood, which resulted in intrinsic stains. The antibiotic binds to the calcium of the teeth and oxidizes enamel as teeth emerge from the gums, causing deep brown or gray stains.
Genetic Traits: Certain genetic conditions such as dentinogenesis imperfecta, or DI, can cause amber, gray, and even purple teeth. This is caused by poor mineralization of the tooth and can damage the durability of a patient’s teeth, as well as their appearance.
Correcting Intrinsic Stains
Since teeth affected by internal staining cannot be completed treated by normal topical bleaching, our Ramsey dentist provides alternatives to correct the aesthetic issues caused by these conditions. For dental fluorosis and tetracycline staining, porcelain veneers and porcelain crowns are applied to teeth, covering teeth with aesthetic and durable material.
Patients with DI do not have the necessary healthy tooth structure to support veneers. Instead these patients are provided with crowns, overdentures, and dental implants as necessary. These restorations are recommended dependent on the age and individual needs of patients to restore full function and natural smile aesthetics.
