Before You Get Braces From Your Dentist, Here Is What You Need To Know In the recent years, the installation of dental braces has changed significantly. Though the fixing is not painful, after the procedure you will feel some pinch due to the new pressure on your teeth and having new elements in the mouth. You might feel the pain on your lips and gums, but that is because your mouth is not used to the plastic or metal tissues. If everything goes as premeditated; you should have the pain going away after some weeks. If this is not the case, you should inform your dentist.
