It's probably a canker sore. They usually go away on their own in about a week. I tend to get really big painful ones though. They don't get quite so big if I catch them early and rinse with mouthwash or a weak potassium permanganate (disinfectant) solution. </p> <p>My son also had a giant white sore on the inside of his lip at around 18 months. It looked horrible, I could see it without even pulling back his lip. Didn't seem to bother him though, and went away in a couple of days. I still don't know what it was, but am guessing he was worrying his lip because of teething and gave himself a blister. </p> https://boards.hellobee.com/topic/sore-in-childs-mouth#post-2920877 Mon, 16 Nov 2020 14:29:45 +0000 PurplePumps 2920877@https://boards.hellobee.com/ <p>I'd monitor it for a few days and then decide. If it's getting better, no problem. If it's the same, or worse, or more of them, then give them a call. I randomly get canker sores all the time, esp when my diet is bad, so it wouldn't be too alarming to me on its own if he weren't cranky or had a temp. </p> https://boards.hellobee.com/topic/sore-in-childs-mouth#post-2920876 Mon, 16 Nov 2020 14:29:17 +0000 Mrs. Carrot 2920876@https://boards.hellobee.com/ <p>If it's a canker sore and they don't have other symptoms, I wouldn't take them in. My daughter gets them and they typically resolve in a few days. If it's something different and/or there are other symptoms, it would be worth a call to a doc. </p> https://boards.hellobee.com/topic/sore-in-childs-mouth#post-2920872 Mon, 16 Nov 2020 14:07:40 +0000 lisa1783 2920872@https://boards.hellobee.com/ <p>Is it different than a cankersore? </p> https://boards.hellobee.com/topic/sore-in-childs-mouth#post-2920871 Mon, 16 Nov 2020 13:57:53 +0000 JJ2626 2920871@https://boards.hellobee.com/ <p>How old a child? I’d probably wait a few days to see if it goes away and then call. Wouldn’t take it without talking in covid times. </p> https://boards.hellobee.com/topic/sore-in-childs-mouth#post-2920870 Mon, 16 Nov 2020 13:56:34 +0000 CatchAFallingStar 2920870@https://boards.hellobee.com/ <p>Would you take your child to the doctor for a sore on their inner lip? Or just let it go away? </p>
