Do not bite hard objects】 After root canal treatment fillings are mostly transitional materials that can not withstand excessive biting force, but not otherwise easy to break or fall off. The filling material is small, but if you bite your own teeth off the consequences will be very troublesome. The actual fact is that you will be able to get a lot more than just a few of these. If the teeth are not well cleaned, a lot of dirt will accumulate on the teeth, and the tooth bed will become red and swollen and bleed easily, increasing the chance of infection and affecting the subsequent treatment. So be sure to brush your teeth well and flossing is highly recommended to clean the spaces between your teeth? Don’t be afraid of pain】 If pain occurs after treatment, don’t be nervous, most of it is a normal body resistance reaction and will be relieved in a few days. The degree of tooth performance varies from case to case. If the pain is unbearable, you can take effective anti-inflammatory drugs and painkillers first under the guidance of the doctor, or in the emergency dental clinic for emergency treatment. Consult with your doctor and contact him/her for a follow-up appointment. If you cannot make your follow-up appointment on time, please inform the doctor or change your appointment, and be informed of the precautions to take.
