Root canal therapy is a common dental treatment method, which can relieve pain and restore the health of teeth by eliminating infection and inflammation inside teeth. After treatment, in order to protect teeth and make them more beautiful, braces are usually recommended.

As for the service life of braces, it will be affected by many factors, including the condition of teeth, the material and quality of braces, the quality of operation process, the oral hygiene habits of patients and so on. Generally speaking, if the fit between braces and teeth is good, the operation process is smooth, and patients can maintain good oral hygiene habits, then the service life of braces can usually reach several decades.

However, if the teeth are in poor condition, or the material and quality of braces are problematic, the service life of braces may be shortened. In addition, if patients do not pay attention to oral hygiene after treatment, or often eat some hard food, it will also have an impact on the service life of braces.

In order to ensure the service life of braces as much as possible, patients are advised to have regular oral examination and cleaning, maintain good oral hygiene habits, avoid eating hard food, and review and repair regularly according to the doctor's advice.

In a word, after root canal therapy and braces, patients need to have regular oral examination and cleaning, and maintain good oral hygiene habits to prolong the service life of braces as much as possible.
