Can I use anesthesia when filling a tooth?

If there is no pain due to tooth decay and the dental nerve is not damaged, there is no need for anesthesia. You only need to remove the caries and fill the tooth. If the nerve has been damaged and hot or cold pain begins, anesthesia is needed to treat the dental pulp. However, some patients are more sensitive and may request anesthesia when removing the caries.

Since it is a drug, there is a concept of drug resistance or immunity. In other words, some drugs may not work for some people, which means that this person may be immune to the drug.

Report this to the doctor in time so that he can adjust the dosage of anesthetics!

How long does a tooth filling take?

If it is just shallow caries or slight damage without damaging the pulp, the doctor will directly remove the caries, prepare the cavity, fill it with dental materials, restore the tooth shape, and then polish it to make you feel that there is no abnormality in the bite. It usually takes 30 minutes and the cost is about 100-300.

If the caries is too deep and has damaged the pulp, you will also feel obvious pain from hot and cold stimulation and spontaneous pain, especially at night. In this case, root canal treatment is needed. Root canal treatment usually requires 2-4 follow-up visits to complete, each time taking about 0.5-1 hour. The cost depends on the number of follow-up visits, the number of root canals and the filling materials, and is about 800-1600.
