Here we can give you several advices:
For moderate persistent pain, dietary changes can help reduce symptoms. Eat soft foods like soup, eggs, pasta, mashed potatoes, and yogurt.
If you develop mouth sores, do not touch them with your tongue or fingers. Use orthodontic wax to cover braces or archwires that irritate your mouth.
Gargling with warm salt water can relieve pain.
Anesthetic gels and mouth sprays can be especially helpful at night when you cannot sleep. For example “Orasept” or “Lidocaine”.
Take over-the-counter pain relievers according to the dosage in their description. Usually, for pain in the teeth, preparations containing ketoprofen are taken (Ketanov, Ketorol, Ketorolac).
In case of severe pain, as well as in cases of detachment or breakage of parts of the structure, make an appointment with your dentist as soon as possible. If necessary, take Nimesulide (“Nimesil”, “Nise”).
