I noticed these black and red spots inside of cheeks today. Is this something serious or something to worry about?

I just under went through root canal treatment for first moral teeth of left lower side and doctor did the POC ( permanant filling of cement ) today  and she told me that try to eat chewable things like roti n all slowly from that side .. I tried it today but whenever I  chew from that side I feel pressure pain ( like something is tipping on it ) kind ...doctor told me that it will take 3 - 4 days to recover it , once its get settled we will proceed with mountation of ceramic cap over it .. i feel pain only while eating rest time I dont feel pain... I am not taking any medicin for it and doctor also suggested me to not take it . I guess doctor has digged my teeth upto 17 mm and put those things till 17mm . Please confirm is that the common acceptable pain and will last long till next 3-4 days I have taken Ibugesic and moxikind tablets during root canal

My filling have a gap or not ? Because my dentist say its have a gap and need a root canal treatment ?

I had my upper 2nd molar tooth extraction in the end of may in 2020. I want to have dental implant done but according to CBCT reports i don't have enough length to perform surgery. Is short dental implant can be done in my case? Does it have high successful rate? If there is chance of higher risk, won't dental bridges affect other surrounding teeth and damage them in future? I've started to feel depressed 😞
