Ds who is 8 unfortunately had to have a filling on a baby tooth a few weeks ago. Complained about a week ago of pain in the area but by the next mornings no it had settled down and has not mentioned since. Last night at bedtime I was brushing his teeth and some blood came out. He didn't complain of pain but when I pulled his cheek back there was a large swelling on his gum near the site of his filling. It looks like an abscess. I made him rinse his mouth out with salt water and this morning it looks less swollen but it more yellowy. Should I try and get to an emergency dentist today? He is not in any pain and happily eating breakfast this morning.
