As the name suggests, fixed braces cannot be removed. They are glued to the teeth by using the adhesive technique, and they consist of braces fixed to each individual tooth. Depending on the material, fixed braces can be metal or aesthetic (composite, ceramic or sapphire). One of the most frequent questions refers to the period of wearing fixed braces, and the period, naturally, depends on each specific case. They are usually worn from 12 to 18 months, sometimes even longer, with regular check-ups and hygiene maintenance according to the recommendations of the dentist and the orthodontics specialist.
