Clear aligner treatment is an orthodontic treatment used to straighten and align teeth. This treatment is performed using clear, removable aligners and is preferred over traditional metal brackets and wires. The aligners are specially designed to fit the teeth and are replaced at regular intervals. Throughout the treatment process, they gently change the position of the teeth and keep them aligned. Clear aligner treatment makes the process of straightening teeth more aesthetic and comfortable. The duration of the treatment can vary depending on the patient's needs and usually lasts between 6 months and 1.5 years. This treatment is an effective option for people with mild to moderate teeth straightening needs. However, a dentist's assessment is important to determine an appropriate treatment plan.
