Bristles way too soft
These are billed as 'medium' toothbrushes, they are super soft, like little kid toothbrushes.  I don't even feel like they are cleaning my teeth.  No bristle shedding observed (tried two of the pack so far).  The head and handle are a little rough, but I didn't not experience any splinters.  But if your mouth is so sensitive you need this level of softness in a bristle, the wood might be too much for you.
