So I just had my first dentist check up in probably over a decade. Unsurprisingly, there are issues, though I am reasonably happy that he did not tell me that all my teeth are decaying, and it's too late for anything.
On the other hand, after paying what I later found out to be a ridiculous cost for an X-Ray (60 quid), he suggested that I removed my wisdom teeth on the basis that the lower ones have started decaying and it may save me some issue later on. The alternative would be to fill them up, but he said that the decay may happen again in the future, and at some point it may need to be removed if they start causing problems. Plus, as I was thinking of having my teeth alignment corrected, it would free out some space.
At first he suggested that I had just the lower ones removed, but after a while, he suggested I removed both the upper and lower ones. Now to be honest, I do get attached possessions and even more so to part of my body. Plus, the quote I got for having my molars extracted was pretty shocking. If it is something that I should really do (I'll consult another dentist for a second opinion), then I will go ahead with me, but I would like to hear about people's experience/opinion over here.
