Tooth and Mouth Problems

I had braces when I was 13 years old for a year. After that I was given retainers to wear at night. But about 1.5 yrs back, I visited another dentist who said I can stop wearing retainers. But since I stopped, my upper jaw teeth are protruding again and the dentist said I have overbite and it cannot be corrected at my age as its too late. So now again I'm wearing retainers at night so that it doesnt worsen. Is there any treatment for overbite at my age? I have gaps between my teeth which looks bad, so is there anything we can do about that?

Does pacemaker implanted has influence on RCT? Does it have to be done in hospital environment and not in clinics?

I have to go for a RCT for my back tooth. What will be the cost? and the time?

I want to get the crowning done for one my molar teeths. I had done RCT couple of years back. As I was wearing braces that time I couldn’t get the crowing done. Also, I have pacemaker implanted. Is it anything to do with RCT? Recently, I consulted a dentist and I was told even the refilling need to be done before crowning. I could get it done only in the hospital environment as I have packemaker implanted. I checked with the nearby hospitals and there are no much experienced dentists. Pl advise.

I have severe tooth pain caused from wisdom tooth and the tooth immediately next to it. Today i have been taking paracetamol with codeine and ibuprofen, it is doing very little to ease the pain. I have a dentist appointment tomorrow. I'm wondering if i can take phenergan tonight with these other medications to try to get some sleep.
