It is usually possible to brush your teeth after medication has been placed in the tooth. Drugs placed inside the tooth may be the result of pulp and root tip lesions caused by pulpitis or periapical periodontitis, etc., which require root canal treatment. Root canal treatment requires opening the pulp cavity of the tooth, removing the decayed pulp tissue, and then releasing the medication. Generally, the tooth is sealed with a crown after the medication is placed inside the tooth, and you can brush your teeth. After the medication is placed in the tooth, it is important to control the brushing force and time. Try not to brush the tooth with too much force, and avoid biting hard things with the tooth, so as not to damage the tooth and cause the medicine to fall out. Patients with medication in their teeth also need to maintain proper oral hygiene, and it is recommended that you rinse your mouth in a timely manner after eating, so as not to cause infection and prolong the duration of treatment.
