Tooth and Mouth Problems

I had my 4 premolars removed for orthodontic treatment,but now after braces are removed all my teeth from canines to back are slanted inward making my smile hollow and face sunken. I asked my doctor for it,but they said we're technically sound and know what we're doing.I really want to have a broader smile.could this be fixed with the help of retainer? I mean the angle of teeth's to be more outward?

My son had cavities in the lower teeth and the neighbourhood doctor suggested RCT. I went through the many websites as I wanted to avoid RCT. I asked him to cap the cavity and started re-mineralisation by giving Vitamin D - clarified butter - ghee and cod liver oil etc. He doesn't complain of pain , but I just want to be sure all is ok inside his teeth. I am still not in favour of getting the RCT done and want to treat him with natural methods - no surgery.

I am having pain in one of my molar teeth second last teeth on upper left side). Generally its when I drink cold water and also if I chew something (food etc) in that side. However the pain goes away in a couple of minutes. I consulted a doctor and he said the teeth is fine (without any infections). He did and X-ray and said it was fine as well.However he gave me a toothapaste but still I am facing the issue. What can be the cause for it?

I have been smoking since 3 years. Noticed blackness in my gums two days ago and quit smoking since then. Do you think I have cancer? Can there be any easy remedy to treat my blackened gums?
