Be sure to keep in mind that these remedies will not work permanently. You will have to see a dentist eventually.
In the meantime that you do not get to see the dentist, you can use some of the remedies below:
Oil of cloves is a great pain reliever for tooth aches. A drop or two of this oil on the affected area will ease the pain.
Gargling with salt water will ease up the pain a bit.
Using a mouth wash to gargle can also help relieve the pain of the tooth.
A dampened regular tea bag can also help in relieving a tooth ache. Tannin, a natural ingredient in tea, can help in subsiding the pain of the tooth.
Chewing leaves of a guava tree is another simple and effective home remedy for the tooth ache.
For immediate relief from the tooth ache caused by an exposed nerve, putting a garlic clove will help a lot.
Application of an ice pack on the cheek will also help in relieving the tooth ache.
A mixture of turmeric powder in mustard oil applied on the tooth is another remedy.
A few drops (3-4) of vanilla extract will also help in the relief of toothache.
A pinch of pepper powder mixed with clove oil is also said to relieve toothache.
A pain reliever like acetaminophen or aspirin will also relieve pain of the tooth for a while. You can also use Paracetamol.
Sometimes a food particle gets lodged in the chipped tooth, and when it comes in contact with the nerve ending, will cause a lot of pain. Brushing teeth and gargling with water after every meal will help in reducing the chances of this happening.
All the remedies here are for temporary relief and only the dentist will be able to restore the enamel, of the chipped tooth of which the nerve has been exposed, by filling it.
If the tooth's nerve has been damaged, the dentist will remove it and root canal will be done.
Brushing and regularly flossing teeth will prevent tooth aches and keep teeth healthy, so make sure that brushing and flossing are done on a regular basis.
