The dentist will make an exploration and diagnosis of the situation, to establish what is the cause of the problem and what to do to cure it. In general, the treatment consists of removing tartar and dental plaque by applying an ultrasound dental cleaning, if the problem is minor, or one or more dental scrapings will be done to remove the hidden tartar, which is what is under the the gum and is the most dangerous. If scaling does not solve the problem, your dentist may recommend periodontal surgery to access deeper areas of certain teeth that are not accessible from the outside.
