If you feel itchy, it is likely that your gums are red, swollen and uncomfortable. In this case, you need to go to the dentist for a full mouth scaling or basic periodontal treatment to thoroughly clean the plaque and calculus, so that your gums will no longer be red, swollen and bleeding, and the itchy problem will be solved. In another case, localized itching of the gums is most likely due to food embedding, so you can use dental floss to remove the food hidden in the gaps and the gums will stop itching after a few days of recovery. The last case is the occurrence of pericoronitis in the wisdom tooth. In this case, oral anti-inflammatory medication and timely extraction of the wisdom tooth will solve the problem.
