How to whiten teeth affected by tetracycline staining
The whitening issue of tetracycline-stained teeth mainly relates to internal pigment deposition, typically caused by the use of tetracycline antibiotics during childhood. Whitening methods may include scaling, cold light whitening, resin veneers, porcelain veneers, and porcelain crown restoration, with results varying from person to person. A detailed analysis is as follows:
1. Scaling
Removing dental calculus and plaque from the tooth surface through ultrasonic scaling, making teeth appear cleaner and whiter. This method is suitable for mild cases of tetracycline staining where pigmentation is primarily on the tooth surface. However, scaling has limited effectiveness on pigment deposited in the dentin.
2. Cold Light Whitening
Using high-intensity blue light to activate bleaching agents that oxidize and reduce tetracycline stains, removing surface and deep pigmentation. Cold light whitening is suitable for mild to moderate tetracycline staining and can improve tooth color, making teeth appear whiter. This method is quick and does not harm the enamel surface.
3. Resin Veneers
Applying a layer of resin material close in color to natural teeth onto the tooth surface to mask the original tooth color. Resin veneers are suitable for moderate to severe tetracycline staining when the tooth surface has no significant defects. The short-term effect is relatively good, but resin material can be stained by food pigments and requires periodic replacement.
4. Porcelain Veneers
Bonding customized porcelain veneers to the tooth surface to cover color and shape imperfections. Porcelain veneers offer aesthetic appeal, strong stability, realistic color, and relatively minimal damage to teeth. They are suitable for moderate to severe tetracycline staining, especially when the tooth surface has defects or abnormal shape.
5. Porcelain Crown Restoration
Using porcelain crowns to restore tooth color, shape, and chewing function. Porcelain crown restoration provides significant results but requires substantial removal of dental tissue, causing considerable damage to the tooth. It is suitable for severe tetracycline staining accompanied by tooth defects or abnormal shape.
Patients should choose the appropriate method based on their individual conditions, following the recommendations of dentists at正规 hospitals. Additionally, regardless of the chosen method, maintaining good oral hygiene and dental care habits is essential.
