Go to the dentist. Don't regret it like I did. I neglected to go to the dentist for 7 years and when I did, the dentist told me I had 4 cavities. It was painful because I got them done, they were too sensitive to cold/hot so I had them taken out, got temporaries, got those temporaries taken out, and now finally have the real fillings back in my mouth. I don't know how many times I got that thick needle injected into my mouth. 🙁
