Hi I Have An All On 4 Implant. I Am

Hi I have an all on 4 implant. I am spitting and drooling and can't talk very plainly. You can hear the air rushing out when i say any s or sh and can't say ch very well. The bottom snaps in but it made my gums sore. I am very depressed by all of this especially after the amount of money I have paid. Is there a problem or is this normal? It doesn't feel normal.
