The fastest way to stop a toothache is to see a dentist as soon as possible. Until you can get to the dentist, there are several things you can do to manage the pain and reduce the discomfort.
First, it is important to determine the cause of the toothache. If it is due to a cavity, then the dentist can fill the cavity and the pain should stop. If the pain is due to infection, then the dentist may need to prescribe antibiotics or perform a root canal.
If the pain is due to a short-term issue such as a dislodged filling, then you can try to put the filling back in place. In some cases, this can provide immediate relief.
Over-the-counter pain medications can also help to reduce the pain and discomfort. Ibuprofen and acetaminophen can provide temporary relief until you can visit the dentist.
You can also try applying a cold compress to the affected area. This can help to reduce swelling and provide some relief.
Finally, try to avoid eating or drinking anything that is very hot or cold. This can aggravate the pain and make it worse.
In summary, the fastest way to stop a toothache is to visit a dentist. In the meantime, you can try over-the-counter pain medications, a cold compress, and avoiding hot or cold foods or drinks.
