First tooth! Ouch!

My 5.5m old just cut his first tooth 4 days ago and boy that puppy is sharp! How long does it usually take for the tooth to flatten out/really grow out more? I feel like maybe the corner is sticking up furthest (maybe) because like I said that thing is SHARP

Nursing is... Different now lol I don't always feel the tooth when nursing but when I/he unlatches my nipple is sore and tender. I've been doing this a while (over 5 months) and they haven't been so sore since cluster feeding the first couple of weeks

So yeah, again, when can I expect this tooth to flatten out? 😅 My nipples really want the peace of mind lol
