Tooth and Mouth Problems

I still get pain in the tooth which we did a filling in on Saturday. What can I take apart from the pain killer

My tooth is hurting since 2 days especially when I eat sweet food? What is the remedy ?

I always play with the small piece of skin behind my two front teeth but the weekend it was sore and inflamed and I noticed there is a gap forming between my two front teeth. Did I cause this. The swelling is going down now and is no longer sensitive. Will the gap close or do I need to see more dentist?

I have a painful boil on the top left side inside my mouth. It pains alot while Im eating or drinking.

Am a smoker.My lips are in black color.i want to change it.can you please give me a suggestion. Any lip balm could work or not?

What is the cost of implant a teeth? How is it feel after treatment? Is it painful?

I have tooth ache 3 days after Root Canal treatment. What may be driving it? Also, do I need to worry about it?

I have had my 11 tooth extracted, half broke(accident) The cortical plate is missing but the bone length is 5.6mm wide and 14.8mm long Would an implant without bone graft be recommended

I'm due for the root canal next month of my last molar tooth in the bottom jaw as it has formed a cavity. However it has never pained me. Recently I went for a trip where for 2 days I had a headache and I was told by a few friends that I may have a problem of Sinus as I was snoring too. (I may have sinusitis as I snore, easily get dust allergy and quickly catch cold) The problem is I have a pain in my ear and also in my tooth which is close to the ear and I'm not able to understand the reason.

I think I ate something hard and cracked either an old filling, or a part of my tooth. There are no sharp edges at all, and it doesnt hurt.
