When a local anaesthetic is used to thoroughly numb the area being treated. This numbness in your lips, teeth or tongue might last for several hours after the procedure. You should avoid any chewing until the numbness has completely worn off.
Caring for your temporary crown or filling
A temporary filling is normally placed to protect your tooth. It is common for a small portion of a temporary filling to wear away or break off. This usually is not a problem. However, you should take these precautions to ensure that your temporary filling or temporary crown stays securely in place: Avoid chewing gum and eating sticky or hard foods. If possible, chew only on the opposite side of your mouth.
Continue to brush normally. Floss carefully each day, pulling the floss out from the side as you floss next to the temporary – lifting the floss out from the top can cause the temporary to come loose. We may advise you not to floss in some cases.
What if my tooth hurts? For the first few days after your root canal therapy, you may have some discomfort or sensitivity in the tooth that was treated, particularly if there was pain and infection prior to the treatment.
If antibiotics have been prescribed for the infection, it is important that you take them for the full length of time indicated on the prescription, even if all signs of infection are gone. To control discomfort, we recommend that you take an over-the-counter pain reliever (e.g. ibuprofen) following label directions. To further reduce pain and swelling, you can gently swish three times a day with warm salt water. Dissolve a teaspoon of salt in a cup of warm water, then gently swish the water around the tooth and spit.
Please be sure to call our Practice if: Your bite feels uneven. You have persistent pain. You have any questions or concerns. Note: It is important to complete the treatment for the tooth as soon as possible. The long term success depends on a good filling and/or crown to seal up the top of the tooth so that bacteria cannot get back into the roots.
