Do I need to go to the dentist?

The fact that your cracked tooth doesn’t bother you at all is not a good sign, it just means you have gotten used to it and it and the nerve has probably died. This means it is more susceptible to infections underneath the tooth in the gum area. The first stage of gum disease is gingivits (red, irritated, bleeding gums) but if it progresses to periodontitis, a lot of people wont feel irritation anymore. Periodontitis is when the bone starts to get eaten away by bacteria that is trapped in the gums (which is why flossing is a must). When the bone is gone, there is nothing you can do to get it back and that is when you see recession in your gum line.

There is a point at which a cavity cannot be reversed, even with brushing. At that point if you get to the dentist in time you may only need a filling, but if the cavity has reached the pulp of the tooth you will need a root canal.

Almost everyone has wisdom teeth. If you do not have enough room in your mouth for them, they need to be removed. If not, they can become impacted in the bone and cause infection and even damage the teeth next to it if it goes untreated for too long.

I know it must be scary if you have never been to a dentist to go for the first time, but really they are there to help you. There are all sorts of pain management now a days if you are anxious when you go in. They can give you nitrous to relax you while they work on you. I can’t tell you without looking at your mouth what kind of treatment you would need, but your dentist would be able to explain it all to you so you can understand how important it is to make your mouth as healthy as possible. It will benefit you greatly and I hope you decide to go.
