I have an upper molar tooth that is slightly filled for now because it does not have enough tooth that can be crowned.One side is sore when I bite down and the upper pallet above it seems to be a hard knot as though it is part of tooth and is very sore.I can feel it with my tongue
Hello and welcome. Thanks for sharing your concern. The history posted here indicates towards infection. This requires antibiotics and analgesics for five days. Followed by root canal or extraction. An x a can show the underlying infection clearly.Therefore, for now do warm saline rinses and start with antibiotics upon consultation. Hope it helps. Thanks. Take care.
