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.
In general, girls hit puberty between the ages of 8-13, and boys hit puberty between the ages of 9-15. This means that, if you feel tall but you're only 11, you may just be developing faster than a lot of your girl friends, and may be taller than the boys around you, who will take a bit longer to catch up.
