The early stages of orthodontic treatment can be a little harder for adult patients than for teenagers.
Teenagers have the benefit of getting treatment while they are still growing and their mouth is more flexible.
In some cases, adults will need to have teeth removed or will require surgery to expand their jaw to make room for moving the teeth. This may not be fun but anaesthetics and painkillers make this a short-term concern compared to the long-term benefits.
When the orthodontist actually puts in your braces, your mouth may be tender for a few days though this should clear up quickly.
Beyond that, the only time you are likely to notice your braces is when you have them tightened.
Some adults say that they feel like their teeth have come loose at the beginning.
The reason is that when you are older your teeth are more firmly anchored into your jaw.
The orthodontist needs to loosen the little filaments that anchor your teeth before the teeth will move.
This can mean your teeth feel loose. However, the feeling is no reason for concern. They will tighten again after the orthodontic treatment.
Beyond that, the basics of orthodontic treatment are the same at any age. Your mouth will feel tender for a few days after you first get the braces and you will experience some discomfort when your braces are tightened.
