9 month old baby injured his frenulum

Yesterday my 9 month old Baby fell over onto toy as he’s still trying to better at sitting up he sometimes falls over but not often. But he did into the toy and he started bleeding and i noticed his frenulum looks either swollen or red ... i called his dr office yesterday they told me even with a flap of skin there and it turning white it’s fine it’s healing and not much they can do unless it was constantly bleeding or bothering him... which it isn’t as this point and hasn’t since yesterday... I’m just worried because he doesn’t let me look and i can’t tell if it’s swelling a little bit or the flap

Of skin did actually Rip... and I’m in mass we have lots of cases of corona so i don’t want to go to a hospital for nothing and risk getting it over something that might be fine... :( any advice to anybody who went through this with their kids before??!
