A removable retainer, also known as a loose retainer, is a dental appliance that is custom-made to fit the shape of the patient's mouth and teeth. It is typically made of plastic or a combination of plastic and metal wires. The purpose of a removable retainer is to maintain the position of the teeth after orthodontic treatment, such as braces, and prevent them from shifting back to their original position. Patients can take the retainer out for eating, brushing, and flossing, but it should be worn as directed by their orthodontist to ensure the best results. **

To help the tongue heal after being injured by a rough retainer, it is important to first remove the source of irritation by adjusting or replacing the retainer. Keeping the area clean by gently rinsing with salt water can help prevent infection and promote healing. Avoiding spicy or acidic foods that can further irritate the tongue and opting for soft, cool foods can also aid in the healing process. If the injury is severe or does not improve, it is advisable to seek medical attention from a healthcare professional. **

Ultimately, the "better" system depends on the specific needs and values of a society, as well as the balance between individual freedom and social welfare that is desired. **

Both removable and fixed retainers have their own advantages. Removable retainers are convenient for cleaning and allow for easier maintenance of oral hygiene.
