I've got my dentist appointment booked for wednsday to have my mouth guard fitted cause I clench but I want to ask him about a hard small pea sized lump at the back of my cheek and a swollen salivary gland ,when ever I eat I can feel my cheek filling with saliva and it aches for ages after I think it may be a stone but I'm so scared its a tumour has anyone ever had one ?? I've also got my hypnotherapy booked for the 7th fingers crossed it helps xx
