Do you need a blood test for tooth decay?

Generally speaking, we recommend blood tests. Blood tests can mainly check whether there are problems with coagulation, platelets, and other problems. That is to say, after blood tests, we can find some diseases that can affect tooth extraction. If there are, then it is best not to extract teeth, but to control these diseases first, and then extract teeth after the disease is stable. Relatively speaking, it will be safer. In addition to blood tests, we can actually take x-rays, especially CT images. If the wisdom tooth is extracted, it is very necessary to take CT images, firstly to better determine the extraction plan, and secondly to ensure that there are no special problems with the extraction, such as whether there are other lesions around it.
