When the fillings are small or not deep within the tooth,
fillings can be done without being numbed. In the event one
needs it, new dental materials (topical anesthesia) and technique
have tremendously reduced the pain of an injection to very minimal.
Many times patients don't even know that they already have
received the injections. So please do not let this common misconception
keeping you away from necessary dental treatments. Good luck!
size of the fillings needed.
pain threshold level. Older patients don't feel the pain as much because
the nerve in the tooth is far away from the surface of the tooth, and
therefore, you should not feel the pain as much. If your cavity extends to
the first part of dentin only, then you will only feel sensitivity when
your dentist is drilling your decay. But if extends beyond that, then local
anesthesia is recommended. Last, if you have a high pain threshold (the
point at which pain begins to be felt), then you should not feel the pain
as much. Hope that helps!
(not the topical anesthetic used by majority of dentists)
You should be very comfortable during the entire procidure, depending on the size of the filling and the amount of the work required to be done. You need an excellent job with minimal or no discomfort. If the filling is tiny and can be done without numbing, why not ? But if the filling can last for many more years, would still look like new, if both, you and the dentist are relaxed, by you being numb, you should be numb then. I hope this answered your question.
but proper procedure cannot be done without anesthesia
To answer your second question, it can hurt a lot to have a tooth worked on without anesthesia. Again, it will depend on the size of the decay, the skill of the doctor, and other factors like your pain threshold and age. Older patients have smaller nerves and don't feel nearly as much as a younger patient who typically have huge nerves. You can always tell your dentist to try and go slow and if you start to feel pain, get numbed up.
