I couldn’t sleep for a few nights recently because I had toothache. But there was no pain some days ago. So I didn’t go dentistry for a long time. I have a dislike of dentistry especially dentistry sound. But my back teeth’s filling was lack. I went to the dentistry reluctantly. The filling took it. I had bad teeth cavity I got a cavity in my back tooth. I had got a hole in my back tooth. I feel at ease at last. I thought I have to go there again and again.
