Many worry that closing tooth gaps will be painful, but this is not necessarily the case. Orthodontic treatment, such as braces, may cause some discomfort, but this is usually mild and temporary. Other treatment options, such as dental crowns, bonding and veneers, do not cause pain. If you are concerned about pain, discuss your concerns with your dentist. They will be able to explain the different treatment options and help you choose the one that is best for you.
