I went to see a dentist at a public hospital today because I had my teeth cleaned at a private dental clinic about two months ago and I was told I had 7 decayed teeth. The dentist/staff there persuaded me to fill all the decayed teeth. However, since I was busy with my study(studies) and the cost of filling teeth was expensive, I decided not to fill the teeth until I finished my exam. But the thought that I may have to spend a lot of money on my teeth frequently entered my mind(bothered me) and made me anxious. Besides, I saw a lot of content online which said that filling decayed teeth was not something you do once and forget. Apparently the life of filling material was generally only 5-10 years, and it may even speed up the decay. That means I may have to deal with my decayed teeth for the rest of my life. That made me even more worried(anxious). After I finished my exam, I spent more time searching for information about filling teeth. I saw many people sharing their experience of being treated at a private dental clinic and they suggested seeing dentist at public hospitals instead. Hence, I went to a public hospital today, the dentist told me that all the decay in my teeth are still very shallow and there was no need to fill them just yet. He/She advised me to just brush my teeth carefully. There was only one tooth that was a bit serious, but even then, the decay was also shallow and he advised me to take care of this tooth and observe its condition. If the black area were to expand, I would have to fill it . I felt relieved and I definitely won't do anything at a private dental clinic anymore except routine teeth cleaning.
