Porcelain braces may appear to damage the enamel, corrosion, damage to the tooth tissue and other hazards. 1. Damage to tooth enamel: If a patient wants to have a porcelain tooth restoration, the enamel on the surface of the tooth needs to be ground off before the porcelain braces can be worn. The enamel is an important barrier to protect the health of the teeth, so the damage caused to the teeth is very large. 2. Corrosion: If the sealing of the porcelain braces is poor, bacteria will enter the porcelain braces through the gap, which will lead to tooth corrosion, and this corrosion is very serious, and will eventually affect the stability of the braces, and even tooth loss. 3. Damage: For more severely damaged teeth, root canal treatment is usually also required, which causes damage to the roots and makes the teeth very fragile. If the design of the porcelain braces is also bad, it is likely to lead to the fracture of the tooth and shorten the service life of the tooth. To summarize, if patients need to wear porcelain braces, it is recommended that they visit a regular hospital to avoid causing damage to their teeth.
