For fast toothache relief, sufferers can apply a cold compress to the outside of the mouth or take over-the-counter pain relievers, such as ibuprofen or acetaminophen, according to WebMD. Sufferers can also apply small amounts of a benzocaine-containing antiseptic to the tooth and surrounding gum, as stated by Mayo Clinic.
While an individual is waiting for his dentist appointment, he can rinse his mouth out with warm water before removing any food particles from the affected tooth using dental floss, as recommended by Mayo Clinic. Food between the teeth can sometimes cause toothache, so flossing may provide immediate pain relief. Placing oil of cloves on a piece of cotton and pressing it to the tooth can also provide pain relief. As benzocaine has been linked to a rare but potentially deadly condition known as methemoglobinemia, individuals should consult a doctor before using benzocaine medications for pain relief. Individuals should never use more than the recommended dose or use the medication on children under 2 years of age.
Depending on the cause of the toothache, the dentist may treat the tooth by filling a cavity, extracting the tooth, performing a root canal or prescribing antibiotics, as listed by Boots WebMD. The dentist may also recommend phototherapy to reduce pain and inflammation. Regular brushing and flossing can help prevent future toothaches.
