How does tooth decay hurt?

If the tooth exhibits this decay, it normally causes food impaction pain, or irritation pain caused by heat and cold sensitivity. The only way to treat this pain is to fill the teeth. After repairing, these places will be filled without stimulation. This is a relatively quick method. If there is no time, we can also take some oral painkillers to treat it. For example, oral ibuprofen, diclofenac sodium, loxoprofen sodium, etc. can effectively relieve this pain temporarily, but it is not lasting. Therefore, if the tooth shows continuous damage and shows this pain caused by nerve leakage, root canal treatment of the tooth is needed, or some timely treatment of nerve capping, so that the tooth nerve is not disturbed to some extent and alleviate the occurrence of this pain. Therefore, the most fundamental thing is to find out the cause, symptomatic treatment can be done, medicine can only play a role in alleviating, so it cannot solve the root.
