1. Place Ice On It
Place a small ice cube in a plastic bag, wrap a thin cloth around the bag, and apply it to the aching tooth for about 15 minutes to numb the nerves. You can also place the ice pack on your cheek, over the painful tooth.
Some school of thoughts also believe that if you massage your hand with an ice cube, you can help relieve a toothache. When nerves in your fingers send “cold” signals to your brain, they may override the pain signals coming from your tooth.
All you need to do is wrap up an ice cube in a thin cloth and massage it in the fleshy area between your thumb and forefinger.
Mix equal parts of ginger and cayenne pepper with enough water to make a paste. Proceed to roll a small ball of cotton into the spicy paste to saturate it, then place it on your tooth while avoiding your gums and tongue.
Leave it until the pain fades—or as long as you can stand it. Note that the concoction will likely burn. Also, you can try the spices separately, as both are potent painkillers. The main chemical component of cayenne is capsaicin, and it has been found to help block pain messages from reaching the brain.
3.Swish some salt water
Dissolve a teaspoon of salt in a cup of boiling water to make a pain-killing mouthwash (it can also relieve a sore throat as well). The salt water will clean away irritating debris and help reduce swelling.
Swish it around for about 30 seconds in your mouth before spitting it out. Salt water cleanses the area around the tooth and draws out some of the fluid that is responsible for the swelling. Repeat this treatment as often as needed.
4.Soothe with tea
Peppermint tea does not only have a nice flavour, but it also has some numbing power. Put 1 teaspoon dried peppermint leaves in 1 cup boiling water and steep for 20 minutes. After the tea cools, swish it around in your mouth, then spit it out or swallow.
Furthermore, the astringent tannins in strong black tea may help quell pain by reducing swelling. Another way to use it is to place a warm, wet tea bag against the affected tooth for temporary relief.
5.Rinse Your Mouth With Hydrogen Peroxide
Swishing three percent hydrogen peroxide solution in your mouth can help kill bacteria and relieve some discomfort. This can provide temporary relief if a toothache is accompanied by fever and a foul taste in the mouth.
It is however important to note that this remedy like other toothache remedies is only a stopgap measure until you see your dentist and get the source of infection cleared up. A hydrogen peroxide solution is only for rinsing. Spit it out, then rinse several times with plain water.
