The first line of drug treatment for periodontitis is a type of antibiotic called metronidazole. Metronidazole is an antibiotic that is specifically designed to target and kill the bacteria that cause periodontitis. This bacteria is known as Porphyromonas gingivalis, and it is the most common cause of periodontal disease. Metronidazole is usually prescribed in the form of a mouthwash, which is used to rinse the mouth. This helps to reduce the inflammation that is associated with periodontitis, and it can also help to reduce the amount of bacteria in the mouth.
In addition to metronidazole, other antibiotics may also be prescribed for periodontitis. These antibiotics can help to reduce the amount of bacteria in the mouth, and they can also help to reduce inflammation and promote healing. In some cases, surgeons may suggest a surgical procedure called scaling and root planing, which helps to remove plaque and tartar buildup from the teeth and gums. This procedure can help to reduce the amount of bacteria in the mouth, and it may also be necessary in order to restore the health of the gums and teeth.
It is important to note that while metronidazole is the first line of drug treatment for periodontitis, it is not a cure for the condition. Periodontitis is a chronic condition, and it requires ongoing care. This includes regular visits to the dentist for cleanings, and the use of special mouthwashes and antibiotics. In addition, it is important to practice good oral hygiene, such as brushing and flossing regularly.
