My gums feel swollen and irritated how do i treat it?

Cleaning: You can start with doing a good cleaning at home. It is essential that you brush and floss your teeth daily to prevent cavities and for healthy gums. You should also schedule an appointment with a dentist for a cleaning because there can be areas that you are not able to clean effectively. Finally, it is possible that you may have some type of systemic medical condition causing your gum issue.

Hygiene: Usually inflamed and swollen gums are the result of a condition called periodontitis, which literally means "swelling of the tissues around the teeth", which is almost always caused by bacteria growth on the teeth and gums. Regular and quality brushing and flossing go a long way, but a professional cleaning (maybe even a deep cleaning/scaling) by a hygienist is recommended.

Good oral hygiene: Good brushing and flossing even if gum is bleeding. Brush with soft bristle brush parallel to the gum. Schedule with your dentist for a good cleaning then follow up at home with good oral hygiene regimen to maintain it.

Determine the cause: Usually irritated and inflamed gums are a result of bacteria building up on your teeth at and below the gumline. If the bacterial colonies have hardened into calculus, they need to be scraped off at a dentist's office. If it has been more than six months since your last professional cleaning, now is the time to call for an appointment.
