For the most part, braces do not hurt. The procedure of getting braces simply involves gluing the braces to your teeth. The day after you get braces, your teeth may start feeling sore and may stay sore for a few days. The soreness usually peaks during days 2-3, but should start getting better by days 4-5. Future adjustments may or may not cause you discomfort depending on what is being done to your teeth. To alleviate the discomfort, you can take whatever pain medications you would normally use for a headache.
Because your lips, cheeks and tongue are not accustomed to rubbing against the braces, you may experience sores. The sores may last for one to two weeks until your lips, cheeks, and tongue get used contacting your braces. If there is part of the braces that is irritating your mouth, you can place orthodontic wax to help smooth the rough area of the braces. After your lips, cheeks and tongue get used to the braces, you may even forget you have them on.
