Combined with proper home care and regular dental visits, sealants are extremely effective in preventing tooth decay. They will also potentially save you a lot of time in a dental chair later on, if your teeth start to require fillings, crowns, or even root canals.
The average age is 12, but this does not mean that all girls start at the same age. A girl can start her period anytime between the ages of eight and 15. Usually, the first period starts about two years after breasts first start to grow. If a girl has not had her first period by age 15, or if it has been more than two to three years since breast growth started, she should see a doctor.
Girls develop breasts and start their periods, and boys develop a deeper voice and start to look like men. The average age for girls to begin puberty is 11, while for boys the average age is 12. But thereâs no set timetable, so donât worry if your child reaches puberty before or after their friends. Itâs completely normal for puberty to begin at any point from the ages of 8 to 14. The process takes about four years overall.
