Indeed, few adults wear braces just to make their teeth look attractive. They often have much more serious reason. Some people have too much space between their teeth. This does not look good, but the major problem for such people is that they constantly bite on their gums costing their teeth to loosen.
Very protruding teeth prevent the mouth from closing properly, in which case, people breathe through their mouth and develop plaque and gum problem. The teeth also do not fit together well because of jaw problems. And there are gaps between teeth because certain teeth do not appear when they should. These gaps can be closed using braces, thus obviating the need for an expensive bridge later on. In such cases, braces save money.
Whether braces work or not does not depend widely on your orthodontist. Good hygiene is essential and the patient must also have the self-discipline to continue the treatment that can sometimes take years. Healthy teeth are very important to young and old alike. Most adult patients with braces are extremely pleased with the results of their treatment. Adults who feel they are too old for orthodontic treatment should have a talk with their dentist. Things are not as they used to be, there is a good chance that they will be able to get the right help.
