Need Advice - Impacted lower second molar
I am a patient and appreciate if I can get some advice from the professionals here. I am a 30-year-old woman. I have impacted lower second molars that grow sideways on both left and right side. The second molar is pushing the tooth in the front (I believe that's the first molar). I had bad cavities on both of the impacted lower second molars and first molars because food easily got trapped. I remember my dentist mentioned that the cavities were deep near the nerves. My dentist managed to fill the cavities around 3-4 years ago. However, when I eat / drink cold, the tooth reacts to cold and it gave me like a throbbing sensation on the lower second molars area.
My left hand side is even more complicated. The situation is worse because I lost my lower second premolar 12 years ago and I haven't done any bridge to fill the gap. The upper second premolar starts drifting down which I believe is called super eruption.
I did some researches online, many articles suggested to upright the second molar at young age. I wish I would have gotten a chance to do brace when I was still a teenager. At my age of 30, Is it too late to do the brace?
I am also planning to have a baby in this year or two. I am not sure if doing the brace works well with pregnancy plan.
Instead of upright the second molar, the study mentioned to extract the second molar as a least effective approach. If I choose to extract the lower second molar(s), I wonder if the wisdom tooth is going to come out? Any other alternatives besides these two?
I would like to get the problems as soon as possible but right now I am so dreaded at the same time. Any advice is truly appreciated.
