Sayang, suhu 39.2 tu dah tinggi lah, please bring your child to the doctor atau klinik segera ya , especially kalau sakit gigi + fever macam ni. Better safe than sorry dengan baby kecil. Gigi memang boleh cause fever, tapi doc kena check proper nak confirm apa yang happening. A few of my mum friends' kids pun pernah, tapi semua depa brought them in just to be sure. Take care!
