Hi @superburritov99! This is a common dyntopo artifact that most often happens when using the inflate brush with the Subdivide Edges mode of dyntopo. I get them often too.
To fix bubbles like this, I switch to Subdivide Collapse mode, increase my relative detail size (say from 7 to 10 px) and use my inflate brush to regenerate fresh topology over the artifact spot. Usually I will alternate between inflating out and in until the artifact cleans up. Once it does, I’ll use the smooth brush to finish the fix.
