Should I be embarrassed about getting a filling at 16?
No, most people have a filling by that age. I had 2
People get fillings at all different ages - there is nothing to be embarrassed about. If you need a filling, you want to go ahead and get it to prevent future pain. It's okay to ask your dentist for tips on how to prevent more cavities in the future and that you are brushing twice a day, flossing every day, etc. and wondering what went wrong. It may even have to do with the natural composition of your saliva and you may be more prone to making cavities than other people. Dentists do not (and should not) embarrass patients about their teeth.
no you shouldn't as their is nothing wrong with getting a filling at that age
Seriously, as a Nurse Epidemiologist we don't even think about the "e" word. Its not like you're going in for a pelvic exam. Health care professionals focus on whats going on with your teeth and to fix them. Some people are very susceptible to cavities even with good oral care. From here on out and forever more, there is nothing to be embarrassed over.
