The most common cause of bleeding when you brush is gingivitis, and infection of the gums. Untreated, gingivitis can lead to more serious forms of gum disease that will cause bone and tooth loss. When you see that your gums are bleeding when you brush, you should brush and floss more, not less.
When does puberty happen? There is no set age for puberty so try not to worry if your body changes earlier or later than your friendsâ. For girls, puberty often happens between 10 and 16,1 and for boys between 10 and 18.2. Remember that changes will happen over time.
Most boys start puberty somewhere between the ages of 9 and 16 years. There is a wide age range when puberty starts. That is why some kids in 7th grade still look like young children and others look really grown up. Know that girls usually start puberty earlier than boys.
