I am the Queen of not going to dentists, I hate them, even the smell of their gloves. However, I am horribly vain and do manage to show up when I need my veneers fixed or my whitening trays redone
I make my husband buy my whitening gel from them
Then I don't even have to go through the door.
I managed 8 years with a broken molar, until the infections were coming too quickly. Didn't have a single cavity either once they pulled the tooth - take that 6 month check-ups LOL The infections were annoying, but I chipped a permanent veneer, that was my main reason for going.
Having said that, oragel makes an adult gel - it tastes horrible, but it works. For a more natural approach, a warm, steeped tea bag for an hour on the spot will help, also if there is infection, tea draws it out. Find an Indian (India the country), masseuse, they can massage any pain away, barring that, go get a conditioning treatment done on your hair, it comes with a great head massage that will take the headache away.
Other than that, advil or tylenol, they have anti-inflammatory properties, salt water gargle, I think licorice root or anise both will take pain away.
