Hi, Welcome to icliniq.com. As you said, you are 18 years old, and at this age, it is very common to have bleeding gums. There could be two reasons as you are getting new teeth and another one you are attaining puberty. When you attain puberty, there will be a hormonal imbalance inside the body, leading to swelling in the gums and further bleeding whenever you touch it. If it is painful, you can take a Paracetamol tablet whenever it pains; otherwise, just use mouthwash and keep ice on the area where there is swelling.
