Secret To Not Getting A Root Canal For The Rest Of Your Life
Secret is to have a big margin of safety by filling cavity as early as possible. But here is the problem with that. In order to fill the cavity miles before it to become a root canal, it can't be rely on you. Rather, it has to be rely on your dentist. The tooth is very similar in shape like apple. That's why there are so many dental offices named after apple. I digress little. But the point is, in both apple and tooth, the hardest part is outside. Once the hardest part is broken, the inside is rather soft and takes few months to get bad. Therefore, you have to fix the cavity while it is only on the skin/outside.
Here is the problem. When the cavity is on the outside surface, it doesn't give you any sign/pain at all. So, it has to be the dentist who finds it. Here is more problem with that. You can NEVER tell whether the dentist is telling you the truth or the denist is to upgrade his shiny Infinity car. So, the trust of the dentist is the most imporant factor.
So, when the trust is not there, what the most people do is to wait. Then you will definitely know something is wrong with the tooth. But here is the problem. The filling is already inside like apple and it is often very close to the hollow inside, which is the source of root canal. At that point, you don't need the dentist's trust. You, the dentist, and whole world knows there is a problem. Then what you need is not the dentist's trust but need the dentist's tremendous skill, a.k.a, root canal skill.
In short, the smaller the filling, you need greater dentist's trust. The larger the filling, you need dentist's skill.
