(1) Massage with Ice - Perhaps the most unusual toothache remedy is to rub an ice cube into the V-shaped area where the bones of the thumb and forefinger meet. Gently push the ice over the tooth ache area for 5 to 7 minutes. In a study, Ronald Melzack, Ph.D., a Canadian researcher and past president of the International Association for the Study of Pain, found ice massage eased toothache pain in 60% to 90% of the people who tried it. His research shows this procedure works by sending rubbing impulses along the nerve pathways that the toothache pain would normally travel on. Since the pathways can carry only one signal at a time, rubbing outweighs the pain.
(2) Rinse Your Toothache - Take a mouthful of water (at body temperature) and rinse vigorously, says Dr. Taintor. If your toothache is caused by trapped food, a thorough rinse may dislodge the problem.
(3) Floss Gently - If swishing doesn't work, you can try to pry the popcorn hulls or tiny bits of meat out from between your teeth by flossing, says Dr. Taintor. Be gentle! Your gums are likely to be sore.
(4) Rinse with Salty Water - After each meal and at bedtime, stir 1 teaspoon of salt into an 8-ounce glass of water (again, at body temperature), says Dr. Corn. Hold each mouthful, roll it around your mouth. Spit.
(5) Stay Cool - Keep heat away from your affected area even if it makes the toothache feel better, warns Dr. Corn. "If it is an infection, the heat will draw the infection to the outside of the jaw and make the infection worse."
(6) Use Oil of Cloves - People have been using this over-the-counter remedy for many years, says Richard Shepard, D.D.S., a retired dentist in Durango, Colorado. Most drugstores carry tiny bottles of the oil. Drop a little directly onto the tooth, or dab a little on a cotton ball and pack the elixir next to the tooth ache. If you have a whole clove, place a whole clove between the aching tooth and your cheek. It can be held in place by holding your finger on the outside of the cheek. Chew the cloves a little to release their juice, then leave them in place for half an hour or so or until the pain subsides.
(8) Use Lime Juice - Add some lime juice to asafetida (hing) powder. Soak a piece of cotton and hold it on the tooth and gum.
(9) Keep Your Mouth Shut - If cold air moving past the affected tooth is a problem, just shut off the flow, says Roger P. Levin, D.D.S., president of the Baltimore Academy of General Dentistry and a guest lecturer for the University of Maryland.
(10) Use Turmeric Sticks - Burn some turmeric (haldi) sticks; make a fine powder and use as toothpowder.
(11) Use Ginger - Chew a ginger piece slowly with the aching tooth/teeth to release its juice and leave there for half an hour. Repeat 2-3 times.
(12) Use Star Fruit - Drink the juice of 2-3 star fruits twice a day to get toothache pain relief.
(13) Use Peppermint and Salt - Boil 5 gram of peppermint and a pinch of salt in 1 cup of water. Drink it to relieve toothache.
(14) Use Vanilla Extra - Pour a few drops of Vanilla extract on the dental toothache in question.
(15) Use Oil Of Oregano - Pour a few drops oil of oregano on the toothache and/or adjoining gum.
(16) Avoid Biting Down - If the toothache is caused by a blow to the tooth, try not to use that area when you eat, says Dr. Corn. If nothing is damaged, rest for the tooth may restore its vitality.
(17) Suck On A Moist Teabag - Place it as close to the aching tooth as possible.
(18) Try Acupressure - Press gently but firmly on the sides of either index finger opposite the base of the fingernail.
(19) Be Aware of Pain - Always be alert when it comes to minor (a.k.a. transient) pain because it may be a sign of a problem that can be treated earlier. Sharp pain on biting may be a symptom of a cracked or fractured tooth and even cracked restoration.
(20) Use 2 Pillows @ Night - A toothache increases more at night because the blood goes to the head when you lie down. Elevating your head may help ease the pain.
(21) Good Dental Care - Take proper care of your teeth, by brushing, flossing and get regular check-ups done. It’s the best way to avoid dental pain and to keep your teeth for a lifetime.
